# @file GitLab Runner Configuration
|
|
# @brief Registers GitLab Runner(s) with the given GitLab instance
|
|
# @description
|
|
# This script registers the runner(s) with the given GitLab instance. SaaS GitLab can also be provided as the GitLab instance to register
|
|
# the runners with. The script configures the runners to use either Docker or VirtualBox Executor. Refer to
|
|
# [this page](https://docs.gitlab.com/runner/executors/docker.html) and [this page](https://docs.gitlab.com/runner/executors/virtualbox.html)
|
|
# for details about the available configuration settings.
|
|
#
|
|
# Runners are always tagged with these 2 values: `hostname` and `docker`/`virtualbox` depending on the type of executor. If a list of tags is provided,
|
|
# the runner is tagged with these values in addition to the above mentioned values. If the list of tags is empty, no additonal tags are added and the
|
|
# runner is configured to pickup `untagged` jobs.
|
|
#
|
|
# Configuring other type of executors is not supported by this script.
|
|
#
|
|
# ## Secrets

|
|
# | Secret | Description |
|
|
# |------------------------|------------------------------------------------------------|
|
|
# | `GITLAB_RUNNER_TOKEN` | The token generated when the runner was created in GitLab |
|

|
|
# ## Configuration Variables

# |---------------------|----------------------------------------------------------------------------------------------------------|
|
|
# | `glurl` | The URL of the Gitlab instance to associate the Runner with |
|
|
# | `runnerImage` | Docker image to use to configure the runner. Needed only when configuring `Docker` executor |
|
|
# | `runnerDescription` | Description of this runner |
|
|
# | `runnerTags` | Comma separated list of tags for this runner. See details in the description for more info |
|
|
