About

Job's Done is a tool heavily inspired by Travis, and works in the same way in that configuring a .jobs_done.yaml file in your repository's root to create and trigger Continuous Integration jobs.

Example of a .jobs_done.yaml file:

matrix:
  platform:
  - "win64"
  - "redhat64"

platform-win64:build_batch_commands:
- | 
  python -m venv .env3   || goto eof
  call .env3\Scripts\activate   || goto eof
  pytest --junitxml=tests-{platform}.xml  

platform-redhat64:build_shell_commands:
- |
  python3 -m venv .env3
  source .env3/bin/activate
  pytest --junitxml=tests-{platform}.xml  

junit_patterns:
- "tests.*.xml"

Considering this file is in the root of repository myproject and was pushed to branch feat-71, this will generate two Jenkins jobs:

  • myproject-feat-71-win64
  • myproject-feat-71-linux64

Command-line

Jobs done can be executed in the command-line. Execute from the repository's folder:

$ jobs_done jenkins --username USER https://example.com/jenkins 

This will create/update existing jobs.

Server

jobs done includes a flask end point in jobs_done10.server which can be deployed using Docker.

This end point is tailored to receive the push event from a Webhook of a BitBucket Server instance. A post without any json data will return the installed version, useful to check the installed version and that the end point is correct.

Configuration

Configuration is done by having a .env file (cortesy of python-dotenv) in the root of this repository with the following variables:

JD_JENKINS_URL=https://example.com/jenkins
JD_JENKINS_USERNAME=jenkins-user
JD_JENKINS_PASSWORD=some password

JD_STASH_URL=https://example.com/stash
JD_STASH_USERNAME=stash-user
JD_STASH_PASSWORD=some password

JD_EMAIL_USER=mail-sender@example.com
JD_EMAIL_FROM=JobsDone Bot <mail-sender@example.com>
JD_EMAIL_PASSWORD=email password
JD_EMAIL_SERVER=smtp.example.com
JD_EMAIL_PORT=587

Build

Clone the repository and checkout the tag:

$ git clone https://github.com/ESSS/jobs_done10.git
$ cd jobs_done10
$ git checkout <VERSION> 

Build a docker image:

$ docker build . --tag jobsdone:<VERSION> --build-arg SETUPTOOLS_SCM_PRETEND_VERSION=<VERSION>

Run server

$ docker run --publish 5000:5000 jobsdone:<VERSION>

Hello World

This is an example of a Job's Done file, and what you might expect of its contents.

build_batch_commands:
- "echo MESSAGE: Hello, world!"

description_regex: "MESSAGE\\:(.*)"

Adding this file to a repository hooked into our CI system will create a single job that when executed run a Windows batch command, and later on catches the message echoed and sets that as the build description.

Tests

This is an example of a simple application with tests:

build_batch_commands:
- "pytest --junitxml=pytest_results.xml"

junit_patterns:
- "pytest_results.xml"

This jobs runs pytest in the repository and outputs test results to a file. We also configure the job to look for that file, and present test results to us at then end of the build.

Multiple platforms

The same application as above, but now running on multiple platforms.

platform-win64:build_batch_commands:
- "pytest --junitxml=pytest_results-{platform}.xml"

platform-redhat64:build_shell_commands:
- "pytest --junitxml=pytest_results-{platform}.xml"

junit_patterns:
- "pytest_results.*.xml"

matrix:
  platform:
  - "win64"
  - "redhat64"

Here we add a matrix section to define variations of this job. In this case, we have the platform variable, with two possible values, win64 and redhat64.

One job will be created for each possible combination in the matrix (only two jobs in this case).

Since we can't run batch commands in linux, we add another builder section, build_shell_commands. Using some flags before defining sections we can choose which one will be available in each job.

Values from the matrix can also be used as variables, in this case, {platform} will be replaced by the platform used in that job (win64 or redhat64).

Branch patterns

Branch patterns are used to filter which branches will produce jobs. This list of regular expressions (using Python syntax), ensures that a branch will only produce jobs if at least one of the regular expressions matches the name of the branch.

Here's an example that filter only master and feature branches:

branch_patterns:
- "master"
- "fb-*"

If this section is not defined in the file, all branches will produce jobs.

Job Matrix

As shown in the examples above, the job matrix can be used to create multiple variations of a job. One job for each combination of entries in this matrix is created.

matrix:
  mode:
  - "app"
  - "cases"
  platform:
  - "win64"
  - "linux64"

In this case 4 jobs will be generated:

  • app-win64
  • app-linux64
  • cases-win64
  • cases-linux64

Note that you can use any variables you need, Job's done has no idea what mode or platform means.

There's an exclude clause which can be used to remove particular entries from the matrix:

matrix:
  mode:
  - "app"
  - "cases"
  platform:
  - "win64"
  - "linux64"

mode-cases:platform-win.*:exclude: "yes"  

This will exclude all cases jobs from windows.

String replacement

Variables defined in the job matrix can be used to replace strings in the job file.

On top of matrix variables, there are a few special string templates that can be used in any job:

  • name - Name of the repository
  • branch - Branch being built
matrix:
  platform:
  - "win64"
  - "linux64"

platform-win.*:build_batch_commands:
- "echo Building project {name} in branch {branch} on platform {platform}"  

Note that we use Python's format syntax, so if you need an actual { or } use double braces: {{, }}.

Condition Flags

Variables defined in your job matrix can also be used to control some of the contents in your job file. A common example here is using different builder for windows (bash) and linux (shell).

This is done by adding a prefix to sections of the YAML file, with the variable name and value necessary to use it:

platform-win.*:build_batch_commands:
- "dir ."

platform-linux.*:build_shell_commands:
- "ls -la ."

matrix:
  platform:
  - "win32"
  - "linux64"

Matrix variables can also define aliases, useful to reduce duplication when using such flags. To add aliases, simply use commas to separate additional names for matrix values:

platform-windows:build_batch_commands:
- "dir ."

platform-linux:build_shell_commands:
- "ls -la ."

matrix:
  platform:
  - "win32,windows"
  - "win64,windows"
  - "linux64,linux"

On top of that you can use a special variable branch that's always available, and points to your branch:

branch-master:build_batch_commands:
- "echo Build"

branch-deploy:build_batch_commands:
- "echo Build + Deploy"

Condition values can use Python regex syntax for extra flexibility:

branch-master:build_batch_commands:
- "echo Build"

branch-fb.*:build_batch_commands:
- "echo Feature branch!"

branch-rb.*:build_batch_commands:
- "echo Release branch!"

Development

Create a virtual environment and install it in development mode:

$ python -m virtualenv .env36
$ source .env36/bin/activate
$ pip install -e .[testing]

Run tests:

$ pytest src
