About
Functions to create dynamic envs per $CI_COMMIT_REF_SLUG.
- Rancher project namespaces
- RabbitMQ virtual hosts
- Docker Registry parallel logins
- PostgreSQL databases
Kubectl, rancher cli, helm calls are parallel job safe.
Usage
Add this repo as Git Submodule to a project
git submodule add --name .gitlab-ci-functions -b master -- https://github.com/sysadmws/gitlab-ci-functions .gitlab-ci-functions
P.S. You can directly fetch code from https://raw.githubusercontent.com each time pipeline runs, it is a quick way to start, but not a smart way to use permanently.

- rm -f kubernetes.sh && curl -L -s -o kubernetes.sh https://raw.githubusercontent.com/sysadmws/gitlab-ci-functions/master/kubernetes.sh && . ./kubernetes.sh
