First, have a look at this simple example. Now, read on for more details:

• Find/create a docker-compose file for the app you're interested in.
• Add captainVersion: 4 to the very top of the yaml file.
• Add this section to the end of the yaml file:

caproverOneClickApp:
    variables:
        - id: '$$cap_myapp_version'
          label: Awesome App Version
          defaultValue: '1.2.3'
          description: Check out their Docker page for the valid tags https://hub.docker.com/r/....../tags
          validRegex: '/.{1,}/'
    instructions:
        start: |-
            A description that will be displayed to the user when they
            are installing one click app!
            It can be multiline and contain more details and probably special
            hardware requirements!
        end: |-
            A summary when the app is deployed!
            It can be multiline.

            It can also include the dynamic parameters such as
            $$cap_appname and $$cap_other_random_char
    displayName: The Awesome App
    isOfficial: true ## Only if all images used here are official or from a trusted source.
    description: A relatively short description, less than 200 characters.
    documentation: This docker-compose is taken from example.com

• Variables are prefixed with $$cap
• Variables can be anywhere in the content and they will be replaced by what user enters
• There are 3 special variables that are built-in for all oneclick apps: $$cap_appname, $$cap_root_domain, and $$cap_gen_random_hex(length). For example, if your app needs environment variables with the URL value of the app, you can use $$cap_appname.$$cap_root_domain which resolves to something like myappname.rootdomain.com. Also If you need a default password, you can use $$cap_gen_random_hex(10)
• Each custom variable must have id, label. They could also have defaultValue, validRegex, description.
• IMPORTANT: by default, fields are not required to be filled. If validRegex is not set, the field can be set as empty and ignored by the user.

Even though, the format used by One Click apps is Docker Compose, not all parameters defined in Docker Compose file are parsed out by CapRover. Only the following parameters are used:

• image
• environment
• ports
• volumes
• depends_on
• hostname
• command
• cap_add

Other parameters are currently being ignored by CapRover. If you need a particular parameter, please file an issue, and we'll add it to the respected list.

Aside the the Docker Compose template, services have a special subsection specific to CapRover called caproverExtra which contains service specific parameters that are only available via CapRover and not docker compose. Currently this field can take the following variables:

• dockerfileLines which is a multiline variable, and can be used instead of image property in the service. You must delete the image property if you want to use this parameter. NOTE: dockerfileLines should be used in rare cases where other methods cannot work. Prefer command where possible.
• containerHttpPort is useful when the underlying service uses a custom port for HTTP. If not provided, the default will be "80"
• notExposeAsWebApp can be set to "true" when the underlying service is not an HTTP app. This is useful for databases and other internally used services.
• websocketSupport can be set to "true" to automatically enable Websocket Support. Only supported in versions 1.12+

• Make sure you add an app icon to the logos directory!

After creating your One-Click app yaml file, you need to test it before creating a Pull Request. Here is how you test it:

• Login to your CapRover dashboard
• Go to apps and click on One-Click Apps/Databases
• Select >> TEMPLATE << at the bottom of the dropdown list
• Copy and paste your YAML into the text area, and click NEXT.
• Enter values and make sure it's working as expected.

You may want to build your own private repository. CapRover supports having multiple repositories. You can add new repository URLs to the one click app page. The official one, this one, is available as https://oneclickapps.caprover.com.

To create your own repository:

• Fork this repository
• Delete all existing apps (to avoid duplicate apps), and add your own apps.
• Run npm ci
• Run npm run validate_apps
• Run npm run formatter-write
• Run npm run build
• Host the static content in ./dist using any static file server, or use the included GitHub Pages workflow described below.

The included workflow validates, builds, and publishes the repository when changes are pushed to master.

• Enable GitHub Actions on your fork.
• Go to Settings → Pages.
• Under Build and deployment, set Source to GitHub Actions.
• To use a custom domain, configure it under Settings → Pages and add the required DNS records with your domain provider. The GitHub Actions publishing workflow ignores public/CNAME.
• Push your changes to master.

The default repository URL is https://<owner>.github.io/one-click-apps. No personal access token is required.

Your own private repository can be hosted on a CapRover instance with the newly-added captain-definition file.

To set up your private repository on CapRover:

• Follow the above steps to create your own repository. Update your fork from the upstream master branch if you don't have captain-definition in your fork's root directory
• In your CapRover dashboard, go to apps. Under Create A New App, name it something relevant such as caprover-apps, leave the Has Persistent Data checkbox unchecked, and click Create New App.
• In the new app, go to Deployment, scroll down to Method 3: Deploy from Github/Bitbucket/Gitlab, put the Git url for your forked repository and other requested data, click Save and Update, and then Force Build.
  • Alternatively, an instance of your private repository can be created by making a tarball (.tar) of the contents of the one-click-apps repo and uploading it under Method 2: Tarball.
• Check that the domain listed under HTTP Settings shows the Welcome to nginx! page.
• You should be able to add another domain to this CapRover site, and add it as a third party repository using the below instructions.

In order to add a third party repository:

• Login to your CapRover dashboard
• Go to apps and click on One-Click Apps/Databases and scrolldown to the bottom
• Under 3rd party repositories: copy the URL, (for example: https://Awes0meHub.github.io/caprover-one-click-apps) and paste it in to the text box
• Click the Connect New Repository button

• Awes0meHub: Github repository: https://caproverhub.github.io/caprover-one-click-apps
• Jordan-hall: Github repository: https://oneclickapps.libertyware.io
