How To Use

.gitlab-ci.yml and .github/workflows/godot-ci.yml are included in this project as reference.
For live projects, examples and tutorials using this template check the list below:

• Video tutorial by Kyle Luce
• Video tutorial series by David Snopek
• Repository examples: test-project | game-off.
• Test deploys using this tool: GitHub Pages | GitLab Pages | Itch.io.

Mono/C#

To build a godot project with Mono enabled, change the image tag from barichello/godot-ci:VERSION to barichello/godot-ci:mono-VERSION in .gitlab-ci.yml (Gitlab) or godot-ci.yml (Github). e.g. barichello/godot-ci:mono-3.2.1.

Android

To build a debug release (debug.keystore), use the android_debug job example in the gitlab-ci.yml file.

If you want to export for Android with your own keystore, you can do this with the following steps:

1. Take your generated keystore and convert it to Base64:
   Linux & macOS: base64 release.keystore -w 0
   Windows: certutil -encodehex -f release.keystore encoded.txt 0x40000001
2. Go to GitLab Project > Settings > CI/CD > Variables and copy the Base64-encoded keystore value in a new variable SECRET_RELEASE_KEYSTORE_BASE64 as type variable.
3. Create a second variable SECRET_RELEASE_KEYSTORE_USER as type variable with the alias of your keystore as value.
4. Create a third variable SECRET_RELEASE_KEYSTORE_PASSWORD as type variable with the password of your keystore as value.
5. Use the android job example in the gitlab-ci.yml file.

Platforms

Here's a mapping between each supported CI service, the template jobs and a live example.

CI	Template	Example
GitLab CI	Godot Exports / GitHub Pages / GitLab Pages / Itch.io	GitLab CI Pipelines
GitHub Actions	Godot Exports	GitHub Actions running

Environment configuration

First you need to remove unused jobs/stages from the .yml file you are using as a template(.gitlab-ci.yml or .github/workflows/godot-ci.yml).
Then you have to add these environments to a configuration panel depending on the chosen CI and jobs:

• GitHub: https://github.com/<username>/<project-name>/settings/secrets
• GitLab: https://gitlab.com/<username>/<repo-name>/settings/ci_cd

GitHub Pages

Secrets needed for a GitHub Pages deploy via GitLab CI:

Variable	Description	Example
REMOTE_URL	The git remote where the web export will be hosted (in this case GitHub), it should contain your deploy/personal access token	https://<github username>:<deploy token>@github.com/<username>/<repository>.git
GIT_EMAIL	Git email of the account that will commit to the gh-pages branch.	email@example.com
GIT_USERNAME	Username of the account that will commit to the gh-pages branch.	username

Others variables are set automatically by the gitlab-runner, see the documentation for predefined variables.

Itch.io

Deployment to Itch.io is done via Butler.
Secrets needed for a Itch.io deploy via GitLab CI:

Variable	Description	Example
ITCHIO_USERNAME	Your username on Itch.io, as in your personal page will be at https://<username>.itch.io	username
ITCHIO_GAME	the name of your game on Itchio, as in your game will be available at https://<username>.itch.io/<game>	game
BUTLER_API_KEY	An Itch.io API key is necessary for Butler so that the CI can authenticate on Itch.io on your behalf. Make that API key Masked(GitLab CI) to keep it secret	xxxxxxxxxxxxxxxxxxxxxxxxxxxxxx

Troubleshoot

Problems while exporting

• Check that the export names on export_presets.cfg match the ones used in your CI script.
• Check the paths used in your CI script, some commands may be running in the wrong place if you are keeping the project in a folder (like the test-project template) or not.

Authentication errors with Butler

• If using GitLab check that the 'protected' tag is disabled in the CI/CD variables panel.
