# GitHub Integration
|
||
|
|
|
||
|
|
GitHub can be used to import Terraform configuration, automatically queuing
|
||
|
|
runs when changes are merged into a repository's default branch. Additionally,
|
||
|
|
plans are run when a pull request is created or updated. Atlas will update the
|
||
|
|
pull request with the result of the Terraform plan providing quick feedback on
|
||
|
|
proposed changes.
|
||
|
|
|
||
|
|
## Setup
|
||
|
|
|
||
|
|
Atlas environments are linked to individual GitHub repositories. However, a
|
||
|
|
single GitHub repository can be linked to multiple Atlas environments allowing
|
||
|
|
a single set of Terraform configuration to be used across multiple environments.
|
||
|
|
|
||
|
|
Atlas environments can be linked when they're initially created using the
|
||
|
|
[New Environment](https://atlas.hashicorp.com/configurations/import) process.
|
||
|
|
Existing environments can be linked by setting GitHub details in their
|
||
|
|
**Integrations**.
|
||
|
|
|
||
|
|
To link an Atlas environment to a GitHub repository, you need three pieces of
|
||
|
|
information:
|
||
|
|
|
||
|
|
- **GitHub repository** - The location of the repository being imported in the
|
||
|
|
format _username/repository_.
|
||
|
|
- **GitHub branch** - The branch from which to ingress new versions. This
|
||
|
|
defaults to the value GitHub provides as the default branch for this repository.
|
||
|
|
- **Path to directory of Terraform files** - The repository's subdirectory that
|
||
|
|
contains its terraform files. This defaults to the root of the repository.
