# Dpl [![Build Status](https://travis-ci.com/travis-ci/dpl.svg?branch=master)](https://travis-ci.com/travis-ci/dpl) [![Code Climate](https://codeclimate.com/github/travis-ci/dpl.svg)](https://codeclimate.com/github/travis-ci/dpl) [![Coverage Status](https://coveralls.io/repos/travis-ci/dpl/badge.svg?branch=master&service=github&cache=2019-08-09_17:00)](https://coveralls.io/github/travis-ci/dpl?branch=master) [![Gem Version](https://img.shields.io/gem/v/dpl)](http://rubygems.org/gems/dpl) [![Yard Docs](http://img.shields.io/badge/yard-docs-blue.svg)](http://rubydoc.info/github/travis-ci/dpl)

This version of the README documents dpl v2, the next major version of dpl.
The README for dpl v1, the version that is currently used in production on
Travis CI can be found [here](https://github.com/travis-ci/dpl/blob/v1/README.md).

Dpl is command line tool for deploying code, html, packages, or build artifacts
to various service providers.

It is tightly integrated into Travis CI's [deployment integration](https://docs.travis-ci.com/user/deployment),
but also used, and recommended by others, such as [GitLab](https://docs.gitlab.com/ee/ci/examples/deployment/).

It is maintained by Travis CI, largely community driven, and it has existed
since 2013. If you find support your preferred deployment target missing,
please do not hesitate to get in touch, and we'll help you [add it](#contributing-to-dpl).

## Requirements

Dpl requires Ruby 2.3 or later.

Depending on the deployment target dpl might require additional runtimes (e.g.
Go, Node.js, or Python) to be installed. It also might require sudo access in
order to install a Debian package.

Dpl is generally optimized for usage on Linux systems.

## Installation

This version of dpl is currently released as an `alpha` preview release. In
order to install it, add the `--pre` flag:

```
gem install dpl --pre
```

## Usage

Dpl is meant and optimized for usage in ephemeral build environments, such
as Travis CI, or any other CI/CD pipeline.

Dpl is integrated to Travis CI's build configuration and build script compilation
tooling, so all you need to do is add the proper configuration to your `.travis.yml`
file. Please refer to [the documentation](https://docs.travis-ci.com/user/deployment)
for details.

For usage outside of Travis CI dpl can be executed as follows. Please refer to
the respective [providers](#supported-providers) for details.

```
dpl [provider] [options]
```

Dpl can be used locally, e.g. on your development machine, but it might leave
artifacts that may alter the behaviour of your system. If you encounter this
behaviour and it presents a serious issue to you then please open an
[issue](https://github.com/travis-ci/dpl/issues/new).

### Cleaning up the Git working directory

Dpl v1 has cleaned up the Git working directory by default, using `git stash
--all`. The default for this option has been changed in dpl v2, and users now
need to opt in to cleaning up any left over artifacts from the build process
by passing the option `--cleanup`.

The status of the working directory is relevant only to providers that package
and push it to the respective remote service (e.g. `heroku` when using the
`api` strategy, package registry providers, etc.). Most providers will either
push the latest Git commit, or pull code from a remote repository.

## Maturity Levels

In order to communicate the current development status and maturity of dpl's
support for a particular service the respective provider is marked with one of
the following maturity levels, according to the given criteria:

* `dev` - the provider is in development (initial level)
* `alpha` - the provider is fully tested
* `beta` - the provider has been in alpha for at least a month, and successful real-world production deployments have been observed
* `stable` - the provider has been in beta for at least a month, and there are no open issues that qualify as critical (such as deployments failing, documented functionality broken, etc)

deployment is run on the `master` branch, you would have to ensure that the
`gh-pages` would be updated accordingly during the build.

Dpl is a central component in Travis CI, and has been around for a long time.

This library always has been a community effort first. There probably is not a
single person in the world who is very familiar with all deployment providers
supported by Dpl.

*Thank you all for this!*

This document is for you if you are looking to contribute to dpl, be it by
adding a new deployment provider, fixing a bug, or adding a new feature.

Dpl has a [code of conduct](CODE_OF_CONDUCT.md), please follow it in all
interactions with the project.

Dpl is written in Ruby, and we assume that you familiarize yourself with our
documentation as much as needed.

### Resources

Hopefully helpful resources are:

* This [document](CONTRIBUTING.md)
* The [dpl README](README.md)
* The [dpl API docs](https://www.rubydoc.info/github/travis-ci/dpl) on rubydocs.info
* The [cl README](https://github.com/svenfuchs/cl/blob/master/README.md)

### Navigating the Codebase

All provider specific classes live in [dpl/providers](lib/dpl/providers).
These represent the CLI commands that are executed when the command line
executable `dpl` is run with a given provider name as the first argument.

Each provider is a subclass of `Dpl::Provider`, which is defined in
[dpl/provider.rb](lib/dpl/provider.rb). The provider base class itself
subclasses from `Cl::Cmd`, so it represents an executable sub command of the
main command `dpl`.

For instance, the command `dpl s3 --bucket bucket` instantiates and runs the
provider class [S3](lib/dpl/providers/s3.rb).

The class `Cl::Cmd` contributes the command line options parser, and its
class level DSL. Please see the [cl README](https://github.com/svenfuchs/cl/blob/master/README.md)
for this DSL, and the [S3 provider](/lib/dpl/provider/s3.rb)
for an example how dpl uses it.

The class `Dpl::Provider` adds, amongst other things, the order of stages
(methods) that make up the deployment process:

* `init`
* `install`
* `login`
* `setup`
* `validate`
* `prepare`
* `deploy`
* `finish`

Implementors of concrete provider classes may or may not choose to implement
any of these instance methods according to their needs, and semantics of their
tooling and service providers. Please refer to [Dpl::Provider](/lib/dpl/provider.rb)
for details.

The DSL that is used to declare features, dependencies, environment integration
etc. on the concrete provider classes is defined in the module
`Dpl::Provider::DSL`, in [dpl/provider/dsl](/lib/dpl/provider/dsl.rb).

Also of interest is [Dpl::Ctx::Bash](/lib/dpl/ctx/bash.rb),
the Bash execution context, that runs shell commands, installs dependencies
etc. (while the `Test` context class is used for testing in order to keep your
development machine clean and safe when you run tests locally).

### Lifecycle of the Deployment Process

When a provider class is instantiated and run it will go through a number
of stages that make up the deployment process.

These are documented in [dpl/provider.rb](/lib/dpl/provider.rb).
If you are adding a new deployment provider please familiarize yourself with
this lifecycle.

Feel free to pick and interpret these stages according to the needs and
semantics of the service provider you are adding. By no means do all of these
stages have to be filled in or implmented. The `Provider` base class checks for
these methods, and runs them, if present, so that implementors can choose
semantically fitting names for their providers.

### Deployment Tooling

If you are adding a new deployment provider please choose the tooling you are
going to use carefully.

Dpl is a long lived library, and it has outlived many tools that once were
supported, and no longer are. Thus tooling stability is a major concern for
this project.

Ideally use official CLI tooling supported by the company who's service
provider you are about to add. Often, such CLI tools can be installed via
standard package managers, or manually downloaded using `curl` and installed
with a few simple Bash commands.

Such CLI tooling is preferrable over Ruby gem runtime dependencies as they can
be executed in a child process, and won't introduce any dependency resolution
problems later on.

If no such CLI is available, or it does not look well supported, and your
provider implementation needs to talk to an external HTTP API then please consider
using [Net::HTTP](https://ruby-doc.org/stdlib-2.6.3/libdoc/net/http/rdoc/Net/HTTP.html)
from Ruby's standard library.

If you absolutely have to rely on a runtime Ruby gem dependency, such as a
provider client implementation, please only do so if the gem is supported by
the respective company officially. We may choose to reject including runtime
dependencies that do not look stable or widely supported.

### Runtime Dependencies

Runtime dependencies can be declared on the provider class using the
[DSL](lib/dpl/provider/dsl.rb).

In the case of APT, NPM, and Pip dependencies these will be installed via
shell commands at the beginning of the deployment process.

Ruby gem dependencies will be installed using Bundler's [inline API](https://github.com/bundler/bundler/blob/master/lib/bundler/inline.rb),
at the beginning of the deployment process, so they are available in the same
Ruby process from then on.

### Unit Tests

`Dpl` uses [RSpec](https://github.com/rspec) for tests. The specs reside in
`spec`, and each provider class has a corresponding file
`spec/dpl/providers/*_spec.rb` to hold tests.

Provider tests should be implemented on an input/output acceptance level, as
much as possible.

They use a [Ctx::Test](blob/masterlib/dpl/ctx/test.rb) execution context in
order to avoid running actual shell commands, or actually installing
dependencies at test time. There are custom [RSpec matchers](spec/support/matchers)
in place that help with making assertions against this execution context.

If your provider has to talk to an external HTTP API then ideally use
[Webmock](https://github.com/bblimke/webmock) to stub external requests. If by
any means possible try to avoid mocking or stubbing Ruby client classes (this
is not always possible, but should be considered).

#### Running Unit Tests Locally

You can run the unit test suite locally as follows:

```
bundle install
bundle exec rspec
```

In order to execute tests only for a certain provider you can run:

```
bundle exec rspec spec/dpl/providers/[provider]_spec.rb
```

In order to execute a single test or group of tests add a line number like so:

```
bundle exec rspec spec/dpl/providers/[provider]_spec.rb:25
```

These tests can be run safely on any development machine, anywhere.

### Runtime Dependency Installation Tests

We additionally run tests that exercise runtime dependency installation on
Travis CI.

These live in [.travis/test_install](.travis/test_install). It is not
advisable to run these tests outside of an ephemeral VM or container that can
be safely discarded, as they are going to leave various artifacts around.

### Integration Tests

In order to ensure proper integration with the service providers supported
we also periodically run a test suite that exercises actual deployments to
these providers.

These tests live in [.travis/providers](/.travis/providers), and the are
triggered using the script [trigger](/.travis/trigger).

An integration test consists of:

* A setup script that creates an application (or artifact) to deploy (or
upload).
* A YAML config snippet that configures and triggers the deployment as part of
a build on Travis CI.
* A test script that tests if the deployment was successful.

For example:

* [github-pages/prepare](/.travis/providers/github-pages/prepare)
creates a minimal Git repository that serves an `index.html` on GitHub Pages in a temporary directory.
* [github-pages/travis.yml](/.travis/providers/github-pages/travis.yml)
configures the build to use Dpl 2.0 to deploy this repository to GitHub Pages.
* [github-pages/test](/.travis/providers/github-pages/test)
tests if the deployment was successful.

The tests can be run on Travis CI individually, or combined, by triggering a
build via our API, using the script [.travis/trigger](/.travis/trigger).
This takes a provider name as an argument, and requires a Travis CI API token.

For example, this triggers a build that executes the GitHub Pages test on
Travis CI:

```
.travis/trigger github-pages --token [token]
```

The token can also be set as an environment variable:

```
export TRAVIS_API_TOKEN=[token]
.travis/trigger github-pages
```

The `trigger` script accepts multiple provider names as arguments. If no
arguments are given then tests for all providers will be run.

#### Integration Test Configuration

In the build config YAML snippet make sure to use the branch of your fork for the
deployment tooling, and allow the deployment to run on your branch:

```yaml
deploy:
- provider: [name]
edge:
source: [your-login]/dpl
branch: [your-branch]
on:
branch: [your-branch]
```

Ideally use credentials for an isolated account on the service you are deploying to.
This is generally good practice, and way you can hand things off to someone else.

In order to get things working encrypt the credentials against your fork, and
add them to the build config YAML snippet. If you are in the root directory
of your fork then this command should do the trick:

```
travis encrypt password=[password]
```

If you do not have the `travis` CLI installed you can install it using:

```
gem install travis
```

When you add encrypted credentials to the build config YAML snippet also add a comment
that allows others to identify the account used. E.g:

```yaml
deploy:
- provider: pages
github_token:
# personal access token with repo scope on the account [name]
secure: "[encrypted token]"
```

Open a pull request. In order for us to merge your test, and get it working on
our repository you will need to re-encrypt the credentials against
`travis-ci/dpl`, like so:

```

Whatever minimal deployment you can get working is be a great contribution.
Even if for some reason it proves hard to test the deployment in an automated
fashion, but you have a successful deployment that can be verified manually,
please still open a pull request, and talk to us. Any test is better than no
test.

### Testing Dpl Branches or Forks on Travis CI

It is possible to test a new deployment provider or new functionality of dpl on
Travis CI. In order to do so, add proper configuration on the `edge` key to
your `.travis.yml` like so:

```yaml
deploy:
provider: [name]
edge:
source: [github-handle]/dpl
branch: [branch]
on:
branch: TEST_BRANCH # or all_branches: true
⋮ # rest of your provider's configuration
```

This builds the `dpl` gem on the Travis CI build environment from your
repository, on the given branch. Then it installs the gem built from this code
base, and uses it to run your deployment.

When submitting a pull request, please be sure to run at least one deployment
with the new configuration, and provide a link to the build in your pull
request.

### Code Conventions

Dpl does not follow any strict code styleguide.

Please take a look around other providers, and try to follow a similar code
style to what you find.

Try to use the [DSL](/lib/dpl/provider/dsl.rb) as much
as possible. It keeps the code declarative and readable, so that people not
familiar with Ruby or programming in general can still follow it, and make
sense of it.

If you find yourself trying to achieve something that should be, but is not
supported by the DSL please [open an issue](https://github.com/travis-ci/dpl/issues/new)
about it.

If you are rather unfamiliar with Ruby, and have trouble following our code
style then please submit your pull request anyway, or get in touch, so we can
help.

### Naming Conventions

Dpl uses constant names following Ruby naming conventions. I.e. constant
names use `CamelCase`, and they live in files named in `snake_case.rb`.

If you pick such names for a new provider please try to follow these
conventions.

Real world service provider or company names do not always translate to such
conventional Ruby names one-to-one. That is ok, they don't have to. These Ruby
constant names are representations of real world service and company names in
Ruby code.

Other Ruby libraries often (not always) follow a similar thinking. E.g.
even though Amazon Web Services brand name is `AWS` the module name
they chose in their [aws-sdk](https://github.com/aws/aws-sdk-ruby) is
`Aws`, not `AWS`.

### Updating the README

The [README](/README.md) is generated from a
[template](/lib/dpl/assets/dpl/README.erb.md).

In order to update the README please edit the template, and run:

```
gem install ffi-icu
bin/readme > README.md
```

## Old Issues

If an issue has been left open and untouched for 90 days or more, we
automatically close them. We do this to ensure that new issues are more easily
noticeable, and that old issues that have been resolved or are no longer
relevant are closed. You can read more about this [here](https://blog.travis-ci.com/2018-03-09-closing-old-issues).
