## What's in the Box?
*My Bloody Jenkins* is a re-distribution of the [Official LTS Jenkins Docker image](https://hub.docker.com/r/jenkins/jenkins/) bundled with most popular plugins and
ability to configure most aspects of Jenkins from a **simple** and **single source of truth** represented as YAML.

The image can get the configuration from several data sources such as: File, S3, Environment Variable, HTTP, Kubernetes ConfigMap and Kubernetes Secret.

The image supports "Watching" configuration changes and applying them immediately without restarting jenkins.

The image is "Battle Proven" and serves as the base ground for several Jenkins deployments in production.

## Features
* Configuration Coverage:
* Security Realm (LDAP/AD/Simple Jenkins database)
* Global Security Options
* Authorization
* Jenkins Clouds (Amazon ECS, Kubernetes, Docker)
* Global Pipeline Libraries
* Seed Jobs
* JobDSL Scripts
* Script approvals
* Notifiers (Hipchat, Slack, Email, Email-Ext)
* Credentials (aws, userpass, sshkeys, certs, kubernetes, gitlab, simple secrets)
* Tools and installers (JDK, Ant, Maven, Gradle, SonarQube, Xvfb,Golang)
* Misc. Plugins configuration such as Jira, SonarQube, Checkmarx, Artifactory
* Misc. Configuration options such as Environment variables, Proxy
* Support additional plugins installation during startup without the need to build your own image
* Supports quiet startup period to enable docker restarts with a graceful time which Jenkins is in *Quiet Mode*
* Automated Re-Configure based on configuration data change without restarts
* Supports Dynamic Host IP configuration passed to clouds when Jenkins is running in a cluster
* Supports dynamic envrionment variables from [consul](https://www.consul.io/) and [vault](https://www.vaultproject.io/) using [envconsul](https://github.com/hashicorp/envconsul)
* Supports [configuration-as-code-plugin](https://github.com/jenkinsci/configuration-as-code-plugin) as an alternative configuration syntax

## Why Use the term "Bloody"?
The term "My Bloody Jenkins" came from the fact that I tried to put all my "battle" experience, (i.e. blood, sweat and tears) within the image.
I just thought it is a "catchy" name for this kind of a repository.

## Demo
A [step by step demo](demo) can be found [here](demo)

## k8s Helm Chart
In order to deploy in k8s, A corresponding [Helm Chart](https://github.com/odavid/k8s-helm-charts/tree/master/charts/my-bloody-jenkins) can be found [Here](https://github.com/odavid/k8s-helm-charts/tree/master/charts/my-bloody-jenkins)

```shell
helm repo add odavid https://odavid.github.io/k8s-helm-charts
helm install odavid/my-bloody-jenkins [-f values.yml]
```

## Some Usage Examples
* [docker-plugin cloud](examples/docker/) cloud using Docker Plugin cloud with seed job. See [examples/docker](examples/docker/)
* [kubernetes](examples/kubernetes/) cloud using Minikube with seed job. See [examples/kubernetes](examples/kubernetes/)

## Releases
Docker Images are pushed to [Docker Hub](https://hub.docker.com/r/odavid/my-bloody-jenkins/)

Each release is a git tag v$LTS_VERSION-$INCREMENT where:

* LTS_VERSION is the Jenkins LTS version
* INCREMENT is a number representing that representing the release contents (i.e additional configuration options, bugs in configuration, plugins, etc...)

For each git tag, there following tags will be created:
* $LTS_VERSION-$INCREMENT - one to one releationship with git tag
* $LTS_VERSION - latest release for that LTS version
* lts - represents the latest release

Each master commit, will be tagged as latest

```bash
# get the latest release, alpine
docker pull odavid/my-bloody-jenkins:lts
# get the latest debian release
docker pull odavid/my-bloody-jenkins:lts-debian
# get the latest jdk11 release
docker pull odavid/my-bloody-jenkins:lts-jdk11

# get the latest 2.164.1 LTS
docker pull odavid/my-bloody-jenkins:2.164.1
# get the latest 2.164.1 debian LTS
docker pull odavid/my-bloody-jenkins:2.164.1-debian
# get the latest 2.164.1 jdk11 LTS
docker pull odavid/my-bloody-jenkins:2.164.1-jdk

# get a concrete 2.164.1 release
docker pull odavid/my-bloody-jenkins:v2.164.1-109

# get the latest unstable image (alpine)
docker pull odavid/my-bloody-jenkins
# get the latest unstable debian image
docker pull odavid/my-bloody-jenkins:debian
# get the latest unstable jdk1 image
docker pull odavid/my-bloody-jenkins:jdk11
```

### Alternate docker registry

The docker image is also published to `ghcr.io`
So you can also pull it from `ghcr.io/odavid/my-bloody-jenkins:`

## Environment Variables
The following Environment variables are supported

* `JENKINS_ENV_ADMIN_USER` - (***mandatory***) Represents the name of the admin user. If LDAP is your choice of authentication, then this should be a valid LDAP user id. If Using Jenkins Database, then you also need to pass the password of this user within the [configuration](#configuration-reference).

* __JAVA_OPTS\_*__ - All JAVA_OPTS_ variables will be appended to the JAVA_OPTS during startup. Use them to control options (system properties) or memory/gc options. I am using few of them by default to tweak some known issues:
* JAVA_OPTS_DISABLE_WIZARD - disables the Jenkins 2 startup wizard
* JAVA_OPTS_CSP - Default content security policy for HTML Publisher/Gatling plugins - See [Configuring Content Security Policy](https://wiki.jenkins.io/display/JENKINS/Configuring+Content+Security+Policy)
* JAVA_OPTS_LOAD_STATS_CLOCK - This one is sweet (: - Reducing the load stats clock enables ephemeral slaves to start immediately without waiting for suspended slaves to be reaped

* `JENKINS_ENV_CONFIG_YAML` - The [configuration](#configuration-reference) as yaml. When this variable is set, the contents of this variable can be fetched from Consul and also be watched so jenkins can update its configuration everytime this variable is being changed. Since the contents of this variable contains secrets, it is wise to store and pass it from Consul/S3 bucket. In any case, before Jenkins starts, this variable is being unset, so it won't appear in Jenkins 'System Information' page (As I said, blood...)

* `JENKINS_ENV_CONFIG_YML_URL` - A comma separated URLs that will be used to fetch the configuration and updated jenkins everytime the change. This is an alternative to __JENKINS_ENV_CONFIG_YAML__ setup.
Supported URLs:
* `s3://` - s3 path
* `file://` - a file path (should be mapped as volume) - can be a file, folder or glob expression (e.g. `file:///dir/filename` or `file:///dir` or `file:///dir/*.yml`)
* `http[s]://` - an http endpoint

> Note: If multiple URLs are passed or the file url contains a dir name or a glob expression, all yaml files are being deep merged top to bottom. This behavior enables to separate the configuration into different files or override default configuration.

* `JENKINS_ENV_CONFIG_YML_URL_DISABLE_WATCH` - If equals to 'true', then the configuration file will be fetched only at startup, but won't be watched. Default 'false'

* `JENKINS_ENV_CONFIG_YML_URL_POLLING` - polling interval in seconds to check if file changed in s3. Default (30)

* `JENKINS_ENV_HOST_IP` - When Jenkins is running behind an ELB or a reverse proxy, JNLP slaves must know about the real IP of Jenkins, so they can access the 50000 port. Usually they are using the Jenkins URL to try to get to it, so it is very important to let them know what is the original Jenkins IP Address. If the master has a static IP address, then this variable should be set with the static IP address of the host.

* `JENKINS_ENV_HOST_IP_CMD` - Same as ___JENKINS_ENV_HOST_IP___, but this time a shell command expression to fetch the IP Address. In AWS, it is useful to use the EC2 Magic IP: ```JENKINS_ENV_HOST_IP_CMD='curl http://169.254.169.254/latest/meta-data/local-ipv4'```

* `JENKINS_HTTP_PORT_FOR_SLAVES` - (Default: 8080) Used together with JENKINS_ENV_HOST_IP to construct the real jenkinsUrl for jnlp slaves.

* `JENKINS_ENV_JENKINS_URL` - Define the Jenkins root URL in configuration. This can be useful when you cannot run the Jenkins master docker container with host network and you need it to be available to slaves

* `JENKINS_ENV_ADMIN_ADDRESS` - Define the Jenkins admin email address

* `JENKINS_ENV_PLUGINS` - Ability to define comma separated list of additional plugins to install before starting up. See [plugin-version-format](https://github.com/jenkinsci/docker#plugin-version-format).
> This is option is not recommended, but sometimes it is useful to run the container without creating an inherited image.

* `JENKINS_ENV_QUIET_STARTUP_PERIOD` - Time in seconds. If speficied, jenkins will start in quiet mode and disable all running jobs. Useful for major upgrade.

* `JENKINS_ENV_CONFIG_MODE` - If set to `jcasc`, then [Configuration as Code Plugin](https://github.com/jenkinsci/configuration-as-code-plugin) will be used instead of [Built-in Configuration Handlers](#configuration-reference). See [JCasC Demo](./demo/jcasc-plugin).
> This option will disable all configuration handlers used by the image! If you still want to use builtin configuration handlers, together with dynamic JCasC snippets, please see [Configuration as Code Section](#configuration-as-code-section).

## Configuration Reference
The configuration is divided into main configuration sections. Each section is responsible for a specific aspect of jenkins configuration.

### Environment Variables Section
Responsible for adding global environment variables to jenkins config.
Keys are environment variable names and values are their corresponding values. Note that variables names should be a valid environment variable name.

```yaml
environment:
ENV_KEY_NAME1: ENV_VALUE1
ENV_KEY_NAME2: ENV_VALUE1

```

### Environment variable Substitution and Remove Master Env Vars
You can use ```${ENV_VAR_NAME}``` within the config.yml in order to use environment variables substitution for sensitive data (e.g k8s secrets).
When you pass secrets environment variables to the container, Jenkins will display them in the 'System Info' page. In order to disable that beheviour, you can use
```remove_master_envvars``` section and add regular expressions for variables you don't want to show on the SystemInfo page.

> Escaping `${VAR}` to be used as is without substitution, is done by using `\${VAR}` within the yaml file

```yaml
security:
realm: ldap
managerDN: cn=search-user,ou=users,dc=mydomain,dc=com
managerPassword: '${LDAP_PASSWORD}' # Use LDAP_PASSWORD environment variable
...

remove_master_envvars:
- '.*PASS.*'
- '.*SECRET.*'
- 'MY_SPECIAL_VARIABLE'
```

### Environment Variables Data Sources
The image supports the following data sources for environment variables:
* Native - Environment variables that are passed to the container at startup
* [Files](#environment-variables-values-from-files) - By passing `ENVVARS_DIRS` variable to the container, selected directories can be treated as environment variable source
* [Consul](#using-envconsul-to-fetch-dynamic-environment-variables-from-consul-and-vault) - using [envconsul](https://github.com/hashicorp/envconsul)
* [Vault](#using-envconsul-to-fetch-dynamic-environment-variables-from-consul-and-vault) - using [envconsul](https://github.com/hashicorp/envconsul)

### Environment Variables Values From Files
When using [Environment Variable Substitution](#environment-variable-substitution) within the config.yml file, you can consume environment variables values directly from files contents within folders. This is useful especially when using [k8s secrets volume mappings](https://kubernetes.io/docs/concepts/storage/volumes/#secret)

In order to activate this feature, you need to pass `ENVVARS_DIRS` variable to the container with a comma separated list of directories.

__Example__

Assuming you have the following files within the container:
* /var/secret/username
* /var/secret/password
* /var/other-secret/ssh-key
* /var/other-secret/api-token

Setting the following `ENVVARS_DIRS` environment variable as follows:
```shell
ENVVARS_DIRS=/var/secret/,/var/other-secret
```
Will produce the following environment variables:
* `SECRET_USERNAME` - contents of `/var/secret/username`
* `SECRET_PASSWORD` - contents of `/var/secret/password`
* `OTHER_SECRET` - contents of `/var/other-secret/ssh-key`
* `OTHER_SECRET_API_TOKEN` - contents of `/var/other-secret/api-token`

> Note that variable names are the `_` sanitized and uppercased

### Using envconsul to Fetch Dynamic Environment Variables from Consul and Vault
When using [Environment Variable Substitution](#environment-variable-substitution) within the config.yml file, you can direct the container to automatically fetch them from from [consul](https://www.consul.io/) and [vault](https://www.vaultproject.io/) using [envconsul](https://github.com/hashicorp/envconsul)

The following environment variables need to be provided in order to support it:

* `ENVCONSUL_CONSUL_PREFIX` - Comma separated values of consul key prefixes - Mandatory if using consul to fetch information
* `CONSUL_ADDR` - Consul address (host:port) - Mandatory if using consul to fetch information
* `CONSUL_TOKEN` - Consul ACL Token - The token that used to be authorize the container to fetch the keys from consul - Mandatory if consul ACLs are in use
* `ENVCONSUL_VAULT_PREFIX` - Comma separated values of vault key prefixes - Mandatory if using vault to fetch information
* `VAULT_ADDR` - Vault address \(http\[s]://host:port) - Mandatory if using vault to fetch information
* `VAULT_TOKEN` - Vault ACL Token - The token that used to be authorize the container to fetch the keys from vault - Mandatory
* `ENVCONSUL_UNWRAP_TOKEN` - true/false (default = false), see - tells Envconsul that the provided token is actually a wrapped token that should be unwrapped using Vault's [cubbyhole response wrapping](https://www.vaultproject.io/guides/secret-mgmt/cubbyhole.html)
* `ENVCONSUL_MAX_RETRIES` - (default = 5), How many time the envconsul will retry to fetch data
* `ENVCONSUL_ADDITIONAL_ARGS` - A list of command line arguments to append to the [envconsul](https://github.com/hashicorp/envconsul) CLI. For more details, please read the [envconsul READM](https://github.com/hashicorp/envconsul/blob/master/README.md)

The following parameters are being added to the envconsul CLI:
* -sanitize - replaces all invalid characters to underscore
* -upcase - All keys will become Uppercase

> Due to [An open Issue with envconsul and vault > 0.9.6](https://github.com/hashicorp/envconsul/issues/175), Only Vault versions <= 0.9.6 can be used

### Configuration as Code Section
The `configuration_as_code` yaml section enables *"Mixed-Mode"* configuration style. It enables embedding [configuration as code snippets](https://github.com/jenkinsci/configuration-as-code-plugin/tree/master/demos) within the configuration yaml. This enables out of the box support for plugins configuration that do not have a builtin configuration handler.

```yaml
configuration_as_code:
## https://github.com/jenkinsci/simple-theme-plugin/blob/main/src/test/resources/org/jenkinsci/plugins/simpletheme/ConfigurationAsCode.yml
appearance:
simpleTheme:
elements:
- cssUrl:
url: "https://example.bogus/test.css"
- cssText:
text: ".testcss { color: red }"
- jsUrl:
url: "https://example.bogus/test.js"
- faviconUrl:
url: "https://vignette.wikia.nocookie.net/deadpool/images/6/64/Favicon.ico"

```

### Tools Section
Responsible for:
* Setting up tools locations and auto installers

The following tools are currently supported:
* JDK - (type: jdk)
* Apache Ant (type: ant)
* Apache Maven (type: maven)
* Gradle (type: gradle)
* Xvfb (type: xvfb)

* Shell command installers (type: command)
* Remote Zip/Tar files installers (type: zip)

The tools section is a dict of tools. Each key represents a tool location/installer ID.
Each tools should have either home property or a list of installers property.

Note: For Oracle JDK Downloaders to work, the oracle download user/password should be provided as well.

```yaml

- type: command
label: centos6 # nodes labels that will use this installer
command: /opt/install-ant-xyz
toolHome: # the directoy on the node where the tool exists after running the command
GOLANG-1.8:
type: golang
installers:
- id: '1.8'
```

### Credentials Section
Responsible for:
* Setting up [credentials](https://wiki.jenkins.io/display/JENKINS/Credentials+Plugin) to be used later on by pipelines/tools
* Each credential has an id, type, description and arbitary attributes according to its type
* The following types are supported:
* type: text - [simple secret](https://wiki.jenkins.io/display/JENKINS/Plain+Credentials+Plugin). Mandatory attributes:
* text - the text to encrypt
* type: file - [file secret](https://wiki.jenkins.io/display/JENKINS/Plain+Credentials+Plugin). Mandatory attributes:
* fileName - the fileName
* secretBytes - a base64 encoded string of the file contents.
* type: aws - an [aws secret](https://wiki.jenkins.io/display/JENKINS/CloudBees+AWS+Credentials+Plugin). Mandatory attributes:
* access_key - AWS access key
* secret_access_key - AWS secret access key
* type: userpass - a [user/password](https://github.com/jenkinsci/credentials-plugin/blob/master/src/main/java/com/cloudbees/plugins/credentials/impl/UsernamePasswordCredentialsImpl.java) pair. Mandatory attributes:
* username
* password
* type: sshkey - an [ssh private key](https://wiki.jenkins.io/display/JENKINS/SSH+Credentials+Plugin) in PEM format. Mandatory attributes:
* username
* privatekey - PEM format text
* base64 - PEM format text base64 encoded. Mandatory if privatekey is not provided
* fileOnMaster - A path that is accessible within the docker container. This option is required if privateKey or base64 are not provided. Also, this option is optimal when using _Kubernetes Secrets_
* passphrase - not mandatory, but encouraged

* type: cert - a [Certificate](https://wiki.jenkins.io/display/JENKINS/Credentials+Plugin). Mandatory attributes:
* base64 - the PKCS12 certificate bytes base64 encoded
* fileOnMaster - A path that is accessible within the docker container. This option is required if base64 is not provided. Also, this option is optimal when using _Kubernetes Secrets_
* password - not mandatory, but encouraged
* type: gitlab-api-token - a [Gitlab API token](https://wiki.jenkins.io/display/JENKINS/GitLab+Plugin) to be used with the gitlab plugin
* text - the api token as text

> `Note: Currently the configuration supports only the global credentials domain.`

#### Dynamic Credentials

When the type attribute is not one of the above types, the configuration will try to find the right credential type and configure it using [org.jenkinsci.plugins.structs.describable.DescribableModel](https://github.com/jenkinsci/structs-plugin/blob/master/plugin/src/main/java/org/jenkinsci/plugins/structs/describable/DescribableModel.java)

The logic for dealing with unknown types is as follows:
* If the type: ```fully.qualified.credentials.class.name```, then we will try to use that class name
* ```type: org.jenkinsci.plugins.p4.credentials.P4TicketImpl``` will try to instantiate a [org.jenkinsci.plugins.p4.credentials.P4TicketImpl](https://github.com/jenkinsci/p4-plugin/blob/master/src/main/java/org/jenkinsci/plugins/p4/credentials/P4TicketImpl.java) credentials
* If the type: ```simpleNameWithoutDots```, then we will search all the available __Credentials Descriptors__ and we will try to find the one that starts with the same name ignoring case
* ```type: usernamePassword``` will match [com.cloudbees.plugins.credentials.impl.UsernamePasswordCredentialsImpl](https://github.com/jenkinsci/credentials-plugin/blob/master/src/main/java/com/cloudbees/plugins/credentials/impl/UsernamePasswordCredentialsImpl.java)
* ```type: usernamePasswordImpl``` will match the same above
* ```type: usernamepassword``` will match the same above

> `Note: When dealing with dynamic credentials, you will have to follow the @DataBoundConstructor and @DataBoundSetter rules`

### Notifiers Section
Responsible for Configuration of the following notifiers:
* Mail - [Default Mailer](https://wiki.jenkins.io/display/JENKINS/Mailer) and [Email-ext](https://wiki.jenkins.io/display/JENKINS/Email-ext+plugin) plugin
* [Slack plugin](https://wiki.jenkins.io/display/JENKINS/Slack+Plugin)

```yaml
notifiers:
mail:
host: xxx.mydomain.com
port: 25
authUser: test
autPassword: test
replyToAddress: [email protected]
defaultSuffix: '@mydomain.com'
useSsl: true

baseUrl: http://localhost:8080/
sendAs: JenkinsSlack
credentialId: slack # should be defined in credentials section
```

### Pipeline Libraries Section
Responsible for setting up [Global Pipeline Libraries](https://wiki.jenkins.io/display/JENKINS/Pipeline+Shared+Groovy+Libraries+Plugin)

Configuration is composed of dicts where each top level key is the name of the library and its value contains the library configuration (source, default version)
In case the SCM Source is not git, you can use dynamic configuration based on the SCMSource class.

```yaml
pipeline_libraries:
my-library: # the library name
source:
remote: [email protected]:odavid/jenkins-docker.git
credentialsId: gitsshkey # should be defined in credentials section
defaultVersion: master
implicit: false # Default false - if true the library will be available within all pipeline jobs with declaring it with @Library
allowVersionOverride: true # Default true, better to leave it as is
includeInChangesets: true # see https://issues.jenkins-ci.org/browse/JENKINS-41497

library-from-p4:
## retriever.scm.$class can be symbol or full class name
## Other properties of retriever.scm should match the class properties.
retriever:
scm:
$class: org.jenkinsci.plugins.p4.scm.GlobalLibraryScmSource
path: //xxx/yyy
credential: p4-creds

my-other-lib:
source:
remote:
...

```

### Script Approval Section
Responsible for configuration list of white-listed methods to be used within your pipeline groovy scripts. See [Script Security](https://wiki.jenkins.io/display/JENKINS/Script+Security+Plugin)

```yaml
script_approval:
approvals:
- field hudson.model.Queue$Item task
- method groovy.lang.Binding getVariable java.lang.String
- method groovy.lang.Binding getVariables
- method groovy.lang.Binding hasVariable java.lang.String

```

### Clouds Section
Responsible for configuration of the following docker cloud providers:
* Docker - [type: docker](https://wiki.jenkins.io/display/JENKINS/Docker+Plugin)
* Amazon ECS - [type: ecs](https://wiki.jenkins.io/display/JENKINS/Amazon+EC2+Container+Service+Plugin)
* Kubernetes - [type: kubernetes](https://wiki.jenkins.io/display/JENKINS/Kubernetes+Plugin)

You can define multiple clouds. Each cloud is configured as a dict. For top level key represents the cloud name. Each dict has a mandatory type attritube, and a section of templates representing slave docker templates that correspond to list of labels.

#### Amazon ECS
```yaml
clouds:
# Top level key -> name of the cloud
ecs-cloud:
# type is mandatory
type: ecs
# If your jenkins master is running on EC2 and is using IAM Role, then you can
# discard this credential, otherwise, you need to have an
# aws credential declared in the credentials secion
credentialsId: 'my-aws-key'
# IAM Role to be assumed
assumedRoleArn: 'arn-of-role-to'
# AWS region where your ECS Cluster reside
region: eu-west-1
# ARN of the ECS Cluster
cluster: 'arn:ssss'
# Timeout (in second) for ECS task to be created, usefull if you use large docker
# slave image, because the host will take more time to pull the docker image
# If empty or <= 0, then 900 is the default.
slaveTimeoutInSeconds: 0
# List of templates
templates:
- name: ecsSlave
# Only JNLP slaves are supported
image: jenkinsci/jnlp-slave:latest
# Labels are mandatory!

platformVersion: LATEST
# JVM arguments to pass to the jnlp jar
jvmArgs: -Xmx1g
# ECS memory reservation
memoryReservation: 2048
# ECS cpu reservation
cpu: 1024
# Volume mappings
# If your slave need to build docker images, then map the host docker socket
# to the container docker socket. Also make sure the user within the container
# has privileges to that socket within the entrypoint
volumes:

```

### Seed Jobs Section
Responsible for seed job creation and execution. Each seed job would be a pipeline script that can use [jobDsl pipeline step](https://github.com/jenkinsci/job-dsl-plugin/wiki/User-Power-Moves#use-job-dsl-in-pipeline-scripts)

```yaml
seed_jobs:
# Each top level key is the seed job name
SeedJob:
source:
# git repo where of the seed job
remote: [email protected]:odavid/my-bloody-jenkins.git
credentialsId: gitsshkey
branch: 'master'
triggers:
# scm polling trigger
pollScm: '* * * * *'
# period trigger
periodic: '* * * * *'
# Artifactory trigger
# To use this trigger, Artifactory should be created also by using 'Artifactory' section.
artifactory:
serverId: serverId #Name of Artifactory, same as created Artifactory
path: my-repo/path/to/listen
schedule: 'H/5 * * * *'
# Location of the pipeline script within the repository
pipeline: example/SeedJobPipeline.groovy
# always - will be executed everytime the config loader will run
# firstTimeOnly - will be executed only if the job was not exist
# never - don't execute the job, let the triggers do their job
executeWhen: always #firstTimeOnly always never
# Allow concurrent builds. default - false
concurrentBuild: false

# Define parameters with default values to the seed job
parameters:
a_boolean_param: # the name of the param
type: boolean
value: true
a_string_param:
type: string
value: The String default value
a_password_param:
type: password
value: ThePasswordValue
a_choice_param:
type: choice
choices:
- choice1 ## The first choice is the default one
- choice2
- choice3
a_text_param:
type: text
value: |
A text with
new lines

```

### JobDSL Scripts Section
A "lighter" version of [Seed Jobs Section](#seed-jobs-section). Contains a list of [jobdsl scriptlets](https://github.com/jenkinsci/job-dsl-plugin/wiki). Each script will be executed on startup without creating a dedicated job.

```yaml
# Each list item will be running at startup and during update
job_dsl_scripts:
- |
// Creates a folder
folder('foo')
- |
// Creates a free style project
job('foo/bar'){
scm {
git('git://github.com/foo/bar.git')
}
triggers {
scm('H/15 * * * *')
}
steps {
maven('-e clean test')
}
}
```

### Artifactory Section
Responsible for configuration of [Artifactory Plugin](https://www.jfrog.com/confluence/display/RTF/Jenkins+Artifactory+Plug-in)

```yaml
artifactory:
## Should be true
useCredentialsPlugin: true
## List of artifactory servers
jfrogInstances:
- instanceId: instanceId
platformUrl: https://artifactory1
artifactoryUrl: https://artifactory1
# default false
bypassProxy: true
# default 3
connectionRetry: 10
# default 300
timeout: 200
# use credentialsId
deployerCredentialsConfig:
credentialsId: 'cred1'
# if omitted same as deployerCredentialsConfig
resolverCredentialsConfig:
credentialsId: 'cred2'
```

### SonarQube Section
Responsible for setting up [sonar](https://plugins.jenkins.io/sonar/) plugin

```yaml
# sonar_qube_servers - map of sonar server
sonar_qube_servers:
buildWrapperEnabled: true
installations:
sonar-server-5.6:
serverUrl: https://sonar.domain.com
credentialsId: token
webhookSecretId: webhook
mojoVersion: 5.6
additionalProperties: abc=abc
additionalAnalysisProperties: x=y
triggers:
skipScmCause: true
skipUpstreamCause: true
envVar: ENV_VAR
```

### Running Jenkins behind proxy
When running Jenkins behind a proxy server, add the following to your config yaml file:

```yaml

proxy:
proxyHost:
port:
username: # leave empty if not required
password: # leave empty if not required
noProxyHost:

```

Also, you should pass the following environment variables to the container:
* http_proxy
* https_proxy
* no_proxy

### Custom Config Handler
Sometimes, there is a need to have additional configuration that is not supported by this image.
For that purpose, we have a __custom configuration hook__

In order to use this hook, you will need to create your own docker image and add the following:

* Have ```/usr/share/jenkins/config-handlers/CustomConfig.groovy``` within your image with a single method as an entrypoint:

```groovy
def setup(config){

}
return this
```

* In the configuration yaml file, have a ```customConfig``` top level key that will be passed to the above groovy script.
