Creating a new app repository

The canonical way to create a repository for an app to be distributed and deployed via the Giant Swarm app platform.

These instructions will help you create a new app repository based on our template-app.


Step 1 - Preparation

Since you will need the app and repository name several times on the command line, we first create an environment variable APP_NAME with the new repository name as the value.


export APP_NAME=test-app

Here we assume you want to create the new app and repository named test-app.

Step 2 - Repo creation

In your current command line / shell session, navigate to the directory where you keep git clones.

Note: No need to create an empty sub folder just for the new repo, as this will happen automatically in the next step.

Now create the repository, using our template-app to pre-fill its content. Execute this command to create the new public repository:

gh repo create \
  --clone \
  --public \
  --template=giantswarm/template-app \

Note: The above command will create a public repository and the repo will include the Apache 2.0 license. You can replace the flag --public with --private to create a private repository instead.

Step 3 - Name replacement

Let’s fill in the actual app name in a bunch of places in the new repo’s content, as otherwise we would have just the placeholder {APP-NAME} in there.

Make sure to navigate into your local clone of the repository:

cd ${APP_NAME}

Here are your commands to run:

mv helm/APP-NAME helm/${APP_NAME}

devctl replace \
  -i '{APP-NAME}' ${APP_NAME} \
  --ignore '.git/**' '**'

Commit and push these replacements:

git commit -a -m "Replace placeholder by ${APP_NAME}"
git push origin $(git rev-parse --abbrev-ref HEAD)

Step 4 - Configure settings

Now configure the GitHub repository settings (permission, branch protection, Renovate access, etc.) with one simple command:

devctl repo setup giantswarm/${APP_NAME}

Step 5 - Set up repository automation

To maintain team ownership and keep the repository up-to-date with our standards, you should add the new repository to your team’s list in giantswarm/github. See the README for more details.

Step 6 - Create a container repo

To host container images based on the new repository, set up a repository for it.

Step 7 - Final touches

  • On the repository home page near About, click the cog icon to adjust the repository description and tags. Under “Include in the home page” de-select the Packages and Environments options.
  • Add documentation to the docs/ folder.
  • Replace the of your new repository with meaningful info about the software you’re offering there.
  • Learn how to publish the app in a catalog
