Chamberlain

Automated Jenkins configuration for your GitHub repos.

Libs Used:

Installation

git clone git@github.com:behance/chamberlain.git
cd chamberlain
sudo python setup.py install

Configuration

lives in ~/.chamberlain/config.json, automatically created if DNE

Example:

{
    "github": {
        "auth": {
            "token": "your_oauth_token"
        },
        "orgs": [
            "behanceops"
        ]
    },
    "jenkins": {
        "instances": {
            "bejankins": {
                "jenkins": {
                    "url": "http://bejankins.net:8080",
                    "user": "behance-qe",
                    "password": "password"
                },
                "job_builder": {
                    "ignore_cache": "true"
                }
            }
        },
        "template_params": {
            "bejankins": {
                "gitauth": "aaaaaaaa-0000-aaaa-0000-aaaaaaaaaaaa",
                "ghprauth": "00000000-aaaa-0000-aaaa-000000000000"
            }
        },
        "jobs": [
            {
                "instance": "ci-jenkins",
                "owner": "behanceops",
                "repo": "bephp",
                "templates": [
                    "{repo}-integrations"
                ]
            },
            {
                "instance": "bejankins",
                "owner": "behanceops",
                "templates": [
                    "branch-cookbook-{repo}",
                    "master-cookbook-{repo}"
                ],
                "exclude": [
                    "misc"
                ]
            }
        ]
    }
}

NOTE: all values in the instances config should be strings. Also, the config values mirror the configuration file for jenkins job builder.

i.e.:

  ...

            "bejankins": {
                "jenkins": {
                    "url": "http://bejankins.net:8080",
                    "user": "behance-qe",
                    "password": "password"
                },
                "job_builder": {
                    "ignore_cache": "true"
                }
            }

  ...

is the equivalent of this in Jenkins Job Builder:

[job_builder]
ignore_cache=True

[jenkins]
user=behance-qe
password=password
url=http://bejankins.net:8080

Default values for these configs can be found in the chamberlain.jenkins.configuration module.

Usage

Universal Flags
  • --force-sync, -f : pull repo data from github instead of referencing the cached list of repositories in ~/.chamberlain/github_repos.json.
Universal Args
  • repos : list of repositories to perform actions on.

e.g.: chamberlain generate behance/repo1 matcher_word

Internally, the list of repos that is generated for the commands to use will be filtered based on partial matches for behance/repo1 and matcher_word

Can also be a regex.

Commands

chamberlain map [REPO1 REPO2 ...]

show github repositories and what job templates each one is associated with, or which job templates are associated with the given repos.

this command caches its results in ~/.chamberlain/github_repos.json

chamberlain generate [REPO1 REPO2 ...]

Flags
  -t, --templates   list of directories containing templates (default: [ cwd() ]
  -w, --workspace   prepare a target template directory

WARNING: this will wipe the given --workspace clean.
Given directories with YAML templates, prepares a workspace and generates project-template YAML files in the workspace.

The resulting workspace will look like:

workspace/
         jenkins_instance1/
         jenkins_instance2/
         templates/

templates will contain all template files that are passed in (either cwd() or the list of directories from --templates). The directories for the instances will contain all template files and project files for your repositories.

All project files are given 3 parameters:

  • name: <INSTANCE>-<REPO_FULLNAME>
  • repo: repository shortname
  • sshurl: github SSH url

chamberlain sync [REPO1 REPO2 ...]

Generates the workspace (using the same procedure as the generate command) and runs Jenkins Job Builder in the application workspace, which defaults to ~/.chamberlain/workspace

Same flags as the generate command.

chamberlain gh-sync TEMPLATE_NAME INSTANCE_NAME

When run within a git repository, this command will attempt to take a bunch of github metdata for the repository and inject it into the given TEMPLATE_NAME. Immediately after on success, INSTANCE_NAME will be provisioned with the job.

Metadata fields that are automatically fetched and injected are:

    ghurl: https://github.com/behance/chamberlain
    jobs: ['{owner}-{repo}-make-ci']              # this is automatically updated as a list
    name: ci-jenkins-behance/chamberlain-project  # automatically generated
    owner: behance
    repo: chamberlain
    repo_full_name: behance/chamberlain
    sshurl: git@github.com:behance/chamberlain.git

Notice that in the example config, there is a section in the jenkins config called template_params. You can add default values in here to be injected into the hash above. These are overrides that will be injected on top of the hash above. This is specifically useful when you have credential IDs that you want to inject into your templates to use with things such as the Git SCM Plugin

Any other one-off overrides can be injected via the --params flag in the form of key:value
