Allow default value for variables
Description
Allow variables defined global or on job level to have a default value as for example:
${CI_REGISTRY_IMAGE:-registry.somehost.com/namespace/project}:tag
This would allow people to fork a project and enable their own CI_REGISTRY
and propose new Docker images and/or a new Dockerfile
. But for people which do not enable their registry, using $CI_REGISTRY_IMAGE
will be an empty string, so in merge requests the build will always fail.
Proposal
Example .gitlab-ci.yml
:
build:
image: ${CI_REGISTRY_IMAGE:-registry.gitlab.com/daniel.widerin/testproject}:build
script:
- echo "run fancy stuff..."
