GoMatic scripts for edX pipelines

This repository contains Python 2.7.x code which uses the Gomatic Python module to create pipelines and their stages, jobs, and tasks in GoCD. Gomatic is a domain-specific language (DSL) which allows pipelines to be created via code under source control instead of via the GoCD web GUI.

How to reverse-engineer a pipeline

on -m reverse_engineer --ssl -s <server_address> -p <pipeline_name> --username <username> --password <password> > new_script.py

How to push a pipeline to gocd:

on edxpipelines/pipelines/deploy_ami.py --variable_file ../gocd-pipelines/gocd/vars/tools/deploy_edge_ami.yml --variable_file ../gocd-pipelines/gocd/vars/tools/tools.yml

For testing purposes, you can also perform a dry run of the script:

on edxpipelines/pipelines/deploy_ami.py --dry-run --variable_file ../gocd-pipelines/gocd/vars/tools/deploy_edge_ami.yml --variable_file ../gocd-pipelines/gocd/vars/tools/tools.yml

The dry run will output 2 files:

• config-after.xml
• config-before.xml

You can then diff these files:

 config-before.xml config-after.xml

Cautions and Caveats

• Currently any Secure Variables must be hashed first by the GoCD server before putting them in the script
• GoCD tends to mangle long strings or strings that have carriage returns in them.
