I developed a gitlab pipeline with several stages and builds, now I would like to be able to specify which builds are going to be executed. Ideally I would like to detect the changes under docker_dir/*, but right now I cannot get code to trigger the build.
.ci_rules:
rules:
- if: '$IS_JOB_ON == "TRUE"'
when: always
.job_template: &start_docker
variables:
BUCKET: "ci-jupyterhub-singularity"
tags:
- autoscale-large
rules:
- !reference [ .ci_rules, rules ]
script:
- echo "start job"
build:
stage: build_docker_image
<<: *start_docker
before_script:
- export IS_JOB_ON="TRUE"
rules: are evaluated at the time the pipeline graph is generated. Because rules: are used to make the pipeline in the first place, you cannot use the output of a variable exported in a job to affect rules: evaluation in the same pipeline.
However, detecting changes is a builtin rule feature. For example, to trigger a job when any file changes in the docker_dir/ directory (including subdirectories) you can do the following:
rules:
- changes:
- docker_dir/**/*
