Procedure

1. In your Helm chart, add the global.dynamic parameters required to install a dynamic plugin, as shown in Installing dynamic plugins using the Helm chart

   Note

   The default configuration includes the dynamic-plugins.default.yaml file, which contains all of the dynamic plugins, including TechDocs add-ons, that are preinstalled in Red Hat Developer Hub, whether they are enabled or disabled by default.

2. In your Helm chart, add the default backstage-plugin-techdocs-module-addons-contrib package configuration. For example:

   global:
     dynamic:
       plugins:
         - package: ./dynamic-plugins/dist/backstage-plugin-techdocs-module-addons-contrib
           disabled: false
           pluginConfig:
             dynamicPlugins:

                     - importName: ReportIssue

   Copy to Clipboard Toggle word wrap

3. In the techdocsAddons section of the Helm chart, add importName: <external_techdocs_add-on> for each external TechDocs add-on that you want to add from the specified plugin package. For example:

   global:
     dynamic:
       plugins:
         - package: ./dynamic-plugins/dist/backstage-plugin-techdocs-module-addons-contrib
           disabled: false
           pluginConfig:
             dynamicPlugins:
               frontend:
                 backstage.plugin-techdocs-module-addons-contrib:
                   techdocsAddons:
                     - importName: ReportIssue
                     - importName: <external_techdocs_add-on>

   Copy to Clipboard Toggle word wrap

   where:

   <external_techdocs_add-on>

   Specifies the external TechDocs add-on that you want to install, for example, TextSize or LightBox.

Procedure

1. Install the third-party plugin that you want to use to import your third-party add-on by entering the following command:

   yarn install

   Copy to Clipboard Toggle word wrap
2. Obtain the source code for the third-party TechDocs add-on that you want to use.

3. Export the TechDocs add-on as a dynamic plugin using the following command:

   npx @janus-idp/cli@latest package export-dynamic-plugin

   Copy to Clipboard Toggle word wrap
   Note

   The @latest tag pulls the latest version of the @janus-idp/cli package, which is compatible with the most recent features and fixes. Use a version that is compatible with your Red Hat Developer Hub version.

4. To package the third-party TechDocs add-on as a dynamic plugin, navigate to the root directory where the plugin is stored (not the dist-dynamic directory) and run the npx command with the --tag option to specify the image name and tag. For example:

   npx @janus-idp/cli@latest package package-dynamic-plugins --tag quay.io/<user_name>/<techdocs_add-on_image>:latest

   Copy to Clipboard Toggle word wrap
   Note

   The output of the package-dynamic-plugins command provides the file path to the plugin for use in the dynamic-plugin-config.yaml file.

5. To publish the third-party TechDocs add-on to a Quay repository, push the image to a registry using one of the following commands, depending on your virtualization tool:

   • To use podman, enter the following command:

     podman push quay.io/<user_name>/<techdocs_add-on_image>:latest

     Copy to Clipboard Toggle word wrap

   • To use docker, enter the following command:

     docker push quay.io/<user_name>/<techdocs_add-on_image>:latest

     Copy to Clipboard Toggle word wrap

6. Open your dynamic-plugins.yaml file to view or modify the configuration for the third-party TechDocs add-on. For example:

   plugins:
         - package: oci://quay.io/<user_name>/<techdocs_add-on_image>:latest!<techdocs_add-on_package>
           disabled: false
           pluginConfig:
             dynamicPlugins:
               frontend:
                <techdocs_add-on_package>
                   techdocsAddons:
                     - importName: <third-party_add-on_name>
                      config:
                         props:
                          <techdocs_add-on_property_key>: <techdocs_add-on_property_value>
