## How it works
GitLab ChatOps is built upon two existing features, [GitLab CI/CD](../README.md) and [Slack Slash Commmands](../../user/project/integrations/slack_slash_commands.md).
GitLab ChatOps is built upon two existing features:
- [GitLab CI/CD](../README.md).
- [Slack Slash Commands](../../user/project/integrations/slack_slash_commands.md).
A new `run` action has been added to the [slash commands](../../integration/slash_commands.md), which takes two arguments: a `<job name>` to execute and the `<job arguments>`. When executed, ChatOps will look up the specified job name and attempt to match it to a corresponding job in [.gitlab-ci.yml](../yaml/README.md). If a matching job is found on `master`, a pipeline containing just that job is scheduled. Two additional [CI/CD variables](../variables/README.md#predefined-environment-variables) are passed to the job: `CHAT_INPUT` contains any additional arguments, and `CHAT_CHANNEL` is set to the name of channel the action was triggered in.

Since ChatOps is built upon GitLab CI/CD, the job has all the same features and functions available. There a few best practices to consider however when creating ChatOps jobs:
* It is strongly recommended to set `only: [chat]` so the job does not run as part of the standard CI pipeline.
* If the job is set to `when: manual`, the pipeline will be created however the job will wait to be started.
* It is important to keep in mind that there is very limited support for access control. If the user who triggered the slash command is a developer in the project, the job will run. The job itself can utilize existing [CI/CD variables](../variables/README.html#predefined-environment-variables) like `GITLAB_USER_ID` to perform additional rights validation, however these variables can be [overridden](../variables/README.html#priority-of-environment-variables).

# How to enable or disable GitLab CI/CD
To effectively use GitLab CI/CD, you need a valid [`.gitlab-ci.yml`](yaml/README.md)
file present at the root directory of your project and a
[runner](runners/README.md) properly set up. You can read our
[quick start guide](quick_start/README.md) to get you started.

You can read our [quick start guide](quick_start/README.md) to get you started.
If you are using an external CI/CD server like Jenkins or Drone CI, it is advised
to disable GitLab CI/CD in order to not have any conflicts with the commits status
API.

GitLab CI/CD is exposed via the `/pipelines` and `/jobs` pages of a project.
Disabling GitLab CI/CD in a project does not delete any previous jobs.
In fact, the `/pipelines` and `/jobs` pages can still be accessed, although
it's hidden from the left sidebar menu.
GitLab CI/CD is enabled by default on new installations and can be disabled either
individually under each project's settings, or site-wide by modifying the
settings in `gitlab.yml` and `gitlab.rb` for source and Omnibus installations
respectively.
