# Slack Bot
This Slack bot improves the workflow of development teams. Especially with focus on Jenkins, GitHub, GitLab and Jira, as the integration is working out of the box.
But also custom commands, macros, crons and other project specific commands can be implemented in a simple and flexible way.

# Installation
## 1st) Create+prepare the Slack App:
### Use Manifest file as App template
1. Create a [Slack App](https://api.slack.com/apps?new_app=1) (press "Press "Create New App"")
2. Select "From an app manifest"
3. Select your Workspace
4. Paste this Yaml code:
Click to expand!
```yaml
_metadata:
major_version: 1
minor_version: 1
display_information:
name: slack_bot
background_color: "#382e38"
features:
app_home:
messages_tab_enabled: true
messages_tab_read_only_enabled: false
bot_user:
display_name: bot
always_online: true
oauth_config:
scopes:
bot:
- app_mentions:read
- channels:read
- channels:history
- groups:history
- chat:write
- im:history
- im:write
- mpim:history
- reactions:read
- reactions:write
- users:read
- files:read
- pins:write
settings:
event_subscriptions:
bot_events:
- app_mention
- message.im
interactivity:
is_enabled: true
org_deploy_enabled: false
socket_mode_enabled: true
token_rotation_enabled: false
```
5. Create the App!
6. "Basic information" → "Display Information" → Upload Image (512px+!) + Set a proper name
7. "App Home" → "Show Tabs" → Check "Allow users to send Slash commands and messages from the messages tab"
8. "Basic Information" → "App-Level Tokens" -> "Generate Token and scopes" -> use "bot token" as token name and "connections:write" as scope
8. You will see an App-Level Token (beginning with xapp-). Set it in the config.yaml as "slack.socket_token".
9. Basic Information → "Request to install" + "Install to Workspace" continue there
10. Then you will get another token (displayed in "Install App" tab), starting with "xoxb-". Use it as "slack.token" in the config.yaml
11. In your slack client you can add the bot now in any channel or start a private conversation.
## 2nd) Prepare the config
First prepare the `config.yaml`, just take a look at [config-example.yaml](./config.example.yaml)
- at least the Slack token+socket-token are required) or take a look in config-example.yaml
## 3rd) Run the bot
### Option 1: run via go
1. [install go (at least 1.18)](https://go.dev/doc/install)
2. create a config.yaml (at least the Slack token+socket-token are required) or take a look in config-example.yaml
3. `go run github.com/innogames/slack-bot/v2/cmd/bot`
### Option 2: via Docker
1. [install Docker incl. docker-compose](https://docs.docker.com/get-docker/)
2. clone this repo or at least fetch the docker-compose.yaml
3. add your Slack user id or user name in the "allowed_users:" section of the config.yaml
4. `docker-compose up`
### Option 3: Advanced: when planning working on the bot core
1. [install go](https://go.dev/doc/install)
2. clone/fork this repo
3. run `go run cmd/bot/main.go` or `make run` to run the go application
# Usage
As Slack user, you just have to send a private message to the bot user/app containing the command to execute.
Additionally, you can add the Bot to any channel and execute bot commands in it by prefixing your command with @bot_name, e.g. `@slack-bot start job DailyDeployment`
**Note:** You have to invite the bot into the channel to be able to handle commands.
# Bot Commands
## Help
The `help` command just prints a list of all available commands of this bot.
With `help *command*` you'll get a short description and some examples for a single command.
## Jenkins
The bot is able to start and monitor Jenkins job in a simple but powerful way.
By default, the commands are not available and not visible in the "help", till the "jenkins.host" is defined in the config file.
### Start Jenkins jobs
The `start job` command starts a Jenkins job and shows the current progress. **Attention:** only whitelisted jobs in the config are startable!
In additions, each job can have a configurable `trigger` which make it possible to create custom commands to start jobs. (it's a regexp which takes parameter names into account).
E.g. "start daily deployment" could be the trigger for one Jenkins job. Sending this text to the bot would start the job.
After starting a job, the bot will show the estimated build time and some action buttons. There you can open the logs or abort the build directly.
The bot is also able to parse parameters and lookup branch names using a fuzzy branch search.
**Examples:**
- `trigger job DeployBeta`
- `start job BackendTests TEST-123` (search for a full branch name, containing TEST-123. e.g. feature/TEST-123-added-feature-456)
### Jenkins build notifications
The bot also has the possibility to create one time notifications for Jenkins builds. This might be useful for long-running jobs where the devs are waiting for the result.
**Example:**
- `inform me about build NightlyTests` (watches the most recent running build)
- `inform me about build MyJobName #423` (specify a build number)
- `inform job MyJobName` (alternative syntax)
### Jenkins job notifications
Receive Slack messages for all process builds for the given job:
**Example:**
- `watch JenkinsSelfCheck` notifies about any build of Job `JenkinsSelfCheck`
- `unwatch JenkinsSelfCheck`
### Jenkins status
Small command to disable/enable job execution on Jenkins side.
**Example:**
- `disable job NightlyTests` (disable job on Jenkins)
- `enable job NightlyTests`
### Jenkins retry
When a build failed you are able to retry any build by:
**Example:**
- `retry build NightlyTests` (retries the last build of a job)
- `retry build NightlyTests #100` (retries given build)
### Nodes
`jenkins nodes` lists all available Jenkins nodes. The online/offline status and number of executors are visible.
## Pull Requests
If you just paste a link to a GitHub/GitLab/Bitbucket/Stash Pull request, the bot will track the state of the ticket!
- When a developer was added as reviewer, it will add an "eyes" reaction to show other devs that someone is already taking a look
- When the reviewer approved the ticket, a checkmark is added
- After merging the pull request, it will add a "merge" reaction
You're also able to set custom "approved" reactions. E.g to see directly who or which component/department approved a pull request you can use the name of the reaction or the Unicode character directory
Expand example!
```yaml
pullrequest:
reactions:
merged: custom_merge_arrow
review: 👀
custom_approve_reaction:
nerdydev: "approved_backend"
iamamobiledev: "approved_mobile"
iamamobiledev2: "approved_mobile"
```
**Extra Features:**
For Bitbucket, the bot is able to extract the current build status (e.g. from Jenkins/Bamboo etc) and show failed and running builds (fire reaction) as a reaction (circle arrow reaction). When the build is stable, the build reactions disappear.
## Command Queue
The `queue` command (with the alias `then`) is able to queue the given command, until the currently running command finished.
Example following scenario: you have a build job (which might take some minutes) and a deploy job which relies on the build artifacts. Now you can do:
- `trigger job Build feature1234` to start the Build job with given branch
- `queue trigger job DeployBranch feature1234`
- `queue reply Deployment is done!`
**Other example:**
- `delay 1h`
- `then send message #backend coffee time?`
To see all running background commands (like Jenkins jobs or PR watcher) use this command:
- `list queue`
## Jira
The bot is able to query information from Jira, either from a single ticket, or a whole list of tickets.
By default, the commands are not available and not visible in the "help", till the "jira.host" is defined in the config file.
**Examples**
- `jira TEST-1234`
- `jira 1242` (opens the ticket, using the configured default jira project)
- `jql type=bug and status=open` (use default project by default)
- `jira "Second city"` (text search of tickets in default project)
It's also possible to get a notification when there is a state change in a certain Jira ticket.
**Example**
- `watch ticket PROJ-12234`
## Interactions
It's possible to create buttons which are performing any bot action when pressing the button.
[Slack interactions](https://api.slack.com/interactivity/actions)
**Examples:**
- `add button "Start Deployment" "trigger job LiveDeployment"`
**Note**
- only whitelisted users can click the button
- each button is only active once
## Custom variables
Configure user specific variables to customize bot behavior. E.g. each developer has his own server environment.
**Example:** Having this global config:
```yaml
commands:
- name: Deploy
trigger: "deploy (?P.*)"
commands:
- deploy {{.branch}} to {{ customVariable "defaultServer" }}
```
Each developer can now call ONCE this commands like: `set variable defaultSerer foobarX.local` to register the custom "defaultServer".
When now calling `deploy mater`, it will deploy the `master` branch to `foobarX.local` server.
**Another example**
Here an advanced version which uses [Go templates](https://golang.org/pkg/text/template/).
In the end, the command will generate one subcommand, like:
`reply demo for ` which will post the link to the Slack channel.
```yaml
- name: demo
trigger: "demo (?P\\w+-\\d+)"
commands:
- |
{{ $ticket := jiraTicket .ticketId }}
{{ if $ticket }}
reply demo for <{{ jiraTicketUrl $ticket.Key }}|{{ $ticket.Key }}: {{ $ticket.Fields.Summary }}>
{{ else }}
reply Ticket {{ .ticketId }} not found :white_frowning_face:
{{ end }}
description: Informs the current channel about a demo of a Jira ticket. It directly posts a link to the ticket
examples:
- demo XYZ-1232
```
User can define his default environment once by using `set variable serverEnvironment aws-02`.
Then the `deploy feature-123` will deploy the branch to the defined `aws-02` environment.
Each user can define his own variables.
## Openai/ChatGPT/Dall-e integration
It's also possible to have a [ChatGPT](https://chat.openai.com) like conversation with the official OpenAI integration (GPT3.5)!
Just type "openai" or "chatgpt" before your question to create a new thread which behaves like the well-known ChatGPT page. The content of the last 10 messages is used as context.
To make it work, a valid "openai.api_key" must be provided in the configuration.
**Extended config:**
```yaml
openai:
api_key: "sk-123....789"
initial_system_message: "You are a Slack bot for Project XYZ, please answer shortly."
update_interval: '3s' # fewer Slack messages update during generation
model: gpt-3.5-turbo
temperature: 0.8
log_texts: true # opt in: log all input/output text to the log
```
When using the "openai XXX" command within a existing thread, the previous messages are used as context for further calls.
It also possible to use the function in the templates (like in custom commands or crons).
`{{ openai "Say some short welcome words to @Jon_Doe"}}` would print something like `Hello Jon, welcome! How can I assist you today?`
### DALL-E integration
The bot is also able to generate images with the help of [DALL-E](https://openai.com/blog/dall-e/).
Just prefix you prompt with "dalle" and the bot will generate an image based on your text.
## Quiz command
If you need a small break and want to play a little quiz game, you can do so by calling this command.
No more than 50 questions are allowed.
The questions are from different categories and difficult levels and are either multiple choice or true/false questions.
**Commands**
- `quiz 10` to start a quiz with 10 questions
- `answer 1` to answer a question with the first answer
## Weather command
It's possible to setup [OpenWeatherMap](https://openweathermap.org/) to get information about the current weather at your location.
**Example config:**
```yaml
open_weather:
apikey: "612325WD623562376678"
location: "Hamburg, DE"
units: "metric"
```
## Custom command
Every user is able to define own command aliases.
This is a handy feature to avoid typing the same command every day.
**Example usage**
- `list commands` to just list the defined commands for the current user
- `add command 'myCommand' 'trigger job RestoreWorld 7` -> then just call `myCommand` later
- `add command 'build master' 'trigger job Deploy master ; then trigger job DeployClient master'`
- `delete command 'build master'`
- -> then you can execute `myCommand` to trigger this Jenkins job
## Commands
Defined "Commands" (former called "Macros") are very magical and can be defined in the yaml configuration files.
They have a trigger (a regular expression) and have a list of sub commands which will be executed.
They take parameter groups from regexp into account - so they can be very flexible!
One simple example to start two Jenkins jobs with a given branch name at the same time:
```yaml
commands:
- name: build clients
trigger: "build clients (?P.*)"
commands:
- "reply I'll build {{ .branch }} for you"
- "trigger job BuildFrontendClient {{ .branch }}"
- "trigger job BuildMobileClient {{ .branch }}"
- "then reply done! :checkmark:"
```
**Note**: In the commands, you can use the full set of [template features of go](https://golang.org/pkg/text/template/) -> loops/conditions are possible!
### Template functions
Beside the usual [template features of go](https://golang.org/pkg/text/template/) a bunch of bot specific commands are available in the template scope.
A list of all available functions (with arguments and return types) can be generated by using the `list template functions` command.
**Note:** This template functions can be used in different commands/features:
- [Crons](#cron)
- [Defined commands](#commands) (via .yaml)
- [Custom commands](#custom-command) (defined per user)
- [Jenkins hooks](#jenkins) (like sending custom message when a Job fails)
## Retry
With `retry` or `repeat` your last executed command will be re-executed. -> Useful when a failed Jenkins job got fixed.
## Delay
A small command which might be useful in combination with `command` command or as hook for Jenkins jobs.
Example command: `delay 10m trigger job DeployWorldwide`
As reply you'll get a command to stop the queued job (like `stop timer 123456`). As everyone can send the command, the command can be used to announce a deployment and in doubt, the execution can still be stopped by everyone.
## Reply / send message
`reply` and `send message` are also small commands which are useful in combination with `command` or Jenkins hooks.
**Examples:**
- `send message to #backend The job failed :panic:`
- `delay 10m send message to @peter_pan I should notify you to...`
## Random
Simple command if you are not able to decide between different options
**Examples**
- `random Pizza Pasta` -> produce either "Pizza" or "Pasta"
- `random Peter Paul Tom Jan` -> who has to take about organizing food today?
# Installation
1. Make sure Go version 1.12+ is installed
2. clone the project
3. create config file called `config.yaml` (you can take a look at `config.example.yaml`)
## Run without docker
This command will start the bot, using the `config.yaml` file by default. Use the `-config` argument to use the config file(s) from another location.
```
go run cmd/bot/main.go
```
## Run via docker-compose
**Attention**: Create a config.yaml file first
```
docker-compose up
```
# Configuration
The configuration is managed via simple .yaml files which are storing the credentials for the external services and the custom commands etc.
The easiest way is to just have one `config.yaml` file with all needed options included, the `config.yaml` is loaded by default. It's also possible to split up the configuration into multiple files.
**Example structure with multiple config files:**
- `secret.yaml` containing the credentials for the external services (Slack, Jenkins) - can be managed by puppet/ansible etc.
- `jenkins.yaml` configuration of Jenkins job and their parameters etc
- `project-X.yaml` custom commands for a specific team
- `project-Y.yaml`
To load the multiple config files, use `go run cmd/bot/main.go -config /path/to/config/*.yaml` which merged all configs together.
## Slack
To run this bot, you need a "bot token" for your Slack application. See the [installation](#installation) section on how to create a proper app with the needed tokens.
## Jenkins config
To be able to start or monitor Jenkins jobs, you have to setup the host and the credentials first. The user needs read access to the jobs and the right to trigger jobs for your whitelisted jobs.
```yaml
jenkins:
host: https://jenkins.example.de
username: jenkinsuser
password: secret
```
### Jenkins jobs
To be able to start a job, the job and its parameters have to be defined in the config.
A job without any parameter looks very simple:
```yaml
jenkins:
jobs:
CleanupJob:
```
Then you can use `trigger job CleanupJob` or `start job CleanupJob` to start the job. It will also notify you when the job succeeded or failed (incl. error log).
Next, a job with two parameters:
```yaml
jenkins:
jobs:
RunTests:
parameters:
- name: BRANCH
default: master
type: branch
- name: GROUP
default: all
```
This job can handle two parameters:
- BRANCH: VCS branch name, "master" as default
- GROUP: optional parameter, using "all" as default
If you setup the VSC in the config, you don't have to pass the full branch name, but can use the fuzzy search.
**Example:**
- `start job RunTests` would start "all" groups on master branch
- `start job JIRA-1224 unit` would try to find a matching branch for the ticket number. (Error message if there is no unique search result!)
Now a more complex example with more magic:
```yaml
jenkins:
jobs:
DeployBranch:
trigger: "deploy (?P[\\w\\-_\\.\\/]*) to (?Pprod|test|dev)"
parameters:
- name: BRANCH
default: master
type: branch
- name: ENVIRONMENT
onsuccess:
- reply Tadaa: Take a look on http://{{ .ENVIRONMENT }}.example.com
```
**Step by step:**
The `trigger` is a regular expression to start the job, which may contain named groups. The regexp groups will be matched to the job parameters automatically.
Then you can use `deploy bugfix-1234 to test` to start the Jenkins job.
**Note:** You can always start this job also via `start job DeployBranch master`. The `trigger` is just an alternative.
The `onsuccess` is a hook which will be executed when a job is started via this bot.
In addition, `onsuccess` and `onerror` is also available...e.g. to send custom error messages.
## Cron
It's possible to define periodical commands via crons, using the [robfig/cron library](github.com/robfig/cron).
**Example config**
```yaml
crons:
- schedule: "0 8 * * *"
commands:
- trigger job BuildClients
- then deploy master to staging
channel: "#backend"
```
## VCS / Stash / Bitbucket
To be able to resolve branch names in Jenkins trigger, a VCS system can be configured (at the moment it's just Stash/Bitbucket).
```yaml
vcs:
type: bitbucket
host: https://bitbucket.example.com
username: readonlyuser
password: secret
project: MyProjectKey
repository: repo_name
```
If no config is provided, there is no automated branch lookup and the "branch" parameters are passed 1:1 to the Jenkins job.
## Disable commands/features
Some features might not be needed in your environment. Most ones are not active if the credentials are not provided, like for Jira or Bitbucket.
Some other ones can be disable via config:
```yaml
games:
enabled: false
custom_commands:
enabled: false
custom_variables:
enabled: false
```
# Development
## File structure
- `bot/` contains the code classes of the bot: connection to Slack, user management, command matching...
- `cmd/bot/` entry points aka main.go for the bot and the CLI test tool
- `command/` real command implementing the bot.Command interface
## Create a new (native) command
If you need a new command, which is not implementable with a "command" command, you have to write go code.
- create a new file within the "commands/" directory or one submodule of it
- create a new struct which fulfills the bot.Command interface. The service.SlackClient might be needed as dependency
- GetMatcher() needs to provide the information which command text is matching our command
- register the command in command/commands.go
- restart the bot application
- it's recommended to fulfill the bot.HelpProvider (your command will show up in `help)
- it's also recommended to create an integration test for your command
## CLI tool
There is a handy CLI application which emulates the Slack application...just chat with your local console without any Slack connection!
```
make run-cli
```
## Auto live reload
`make air` to use the ["air auto reload tool"](https://github.com/cosmtrek/air).
## Testing
There are a bunch of tests which can be executed via:
```
make test
```
Test coverage is generated to build/coverage.html
```
make test-coverage
```
