3.10. ダッシュボードの設定

手順

1. サンプル設定で JSON ファイルを作成します。ファイルにはオブジェクトの配列が含まれている必要があります。各オブジェクトはサンプルを表します。

   cat > my-samples.json <<EOF
   [
     {
       "displayName": "<display_name>", 1
       "description": "<description>", 2
       "tags": <tags>, 3
       "url": "<url>", 4
       "icon": {
         "base64data": "<base64data>", 5
         "mediatype": "<mediatype>" 6
       }
     }
   ]
   EOF

   1

   サンプルの表示名。

   2

   サンプルの説明。

   3

   タグの JSON 配列 (例: ["java", "spring"])。

   4

   devfile を含むリポジトリーへの URL。

   5

   アイコンの base64 でエンコードされたデータ。

   6

   アイコンのメディアタイプ。たとえば image/png。

2. サンプル設定で ConfigMap を作成します。

   oc create configmap getting-started-samples --from-file=my-samples.json -n openshift-devspaces

3. 必要なラベルを ConfigMap に追加します。

   oc label configmap getting-started-samples app.kubernetes.io/part-of=che.eclipse.org app.kubernetes.io/component=getting-started-samples -n openshift-devspaces

4. OpenShift Dev Spaces Dashboard ページを更新して、新しいサンプルを表示します。

手順

1. エディター定義設定で my-editor-definition-devfile.yaml YAML ファイルを作成します。

   重要

   metadata.attributes の publisher および version の実際の値を指定してください。これらは、Publisher/name/version 形式のエディター名とともにエディター ID を構築するために使用されます。

   以下に、オプションの値も含め、サポートされている値を示します。

   # Version of the devile schema
   schemaVersion: 2.2.2
   # Meta information of the editor
   metadata:
     # (MANDATORY) The editor name
     # Must consist of lower case alphanumeric characters, '-' or '.'
     name: editor-name
     displayName: Display Name

     # (OPTIONAL) Array of tags of the current editor. The Tech-Preview tag means the option is considered experimental and is not recommended for production environments. While it can include new features and improvements, it may still contain bugs or undergo significant changes before reaching a stable version.
     tags:
       - Tech-Preview
     # Additional attributes
     attributes:
       title: This is my editor
       # (MANDATORY) The publisher name
       publisher: publisher

             attributes:

               type: main
               # An attribute that instructs the service to automatically redirect the unauthenticated requests for current user authentication. Setting this attribute to true has security consequences because it makes Cross-site request forgery (CSRF) attacks possible. The default value of the attribute is false.
               cookiesAuthEnabled: true
               # Defines an endpoint as "discoverable", meaning that a service should be created using the endpoint name (i.e. instead of generating a service name for all endpoints, this endpoint should be statically accessible)
               discoverable: false
               # Used to secure the endpoint with authorization on OpenShift, so that not anyone on the cluster can access the endpoint, the attribute enables authentication.
               urlRewriteSupported: true
             # Port number to be used within the container component
             targetPort: 3100
             # (OPTIONAL) Describes how the endpoint should be exposed on the network (public, internal, none)
             exposure: public

             protocol: https
       # Mandatory name that allows referencing the component from other elements
     - name: checode
       # (OPTIONAL) Allows specifying the definition of a volume shared by several other components. Ephemeral volumes are not stored persistently across restarts. Defaults to false
       volume: {ephemeral: true}
   # (OPTIONAL) Bindings of commands to events. Each command is referred-to by its name
   events:
     # IDs of commands that should be executed before the devworkspace start. These commands would typically be executed in an init container
     preStart:
       - init-container-command
     # IDs of commands that should be executed after the devworkspace has completely started. In the case of Che-Code, these commands should be executed after all plugins and extensions have started, including project cloning. This means that those commands are not triggered until the user opens the IDE within the browser
     postStart:
       - init-che-code-command
   # (OPTIONAL) Predefined, ready-to-use, devworkspace-related commands
   commands:
       # Mandatory identifier that allows referencing this command

         commandLine: 'nohup /checode/entrypoint-volume.sh > /checode/entrypoint-logs.txt
           2>&1 &'

2. エディター定義コンテンツを使用して ConfigMap を作成します。

   oc create configmap my-editor-definition --from-file=my-editor-definition-devfile.yaml -n openshift-devspaces

3. 必要なラベルを ConfigMap に追加します。

   oc label configmap my-editor-definition app.kubernetes.io/part-of=che.eclipse.org app.kubernetes.io/component=editor-definition -n openshift-devspaces

4. OpenShift Dev Spaces ダッシュボードページを更新して、新しい利用可能なエディターを確認します。

手順

1. シークレットを作成します。

   oc apply -f - <<EOF
   apiVersion: v1
   kind: Secret
   metadata:
     name: devspaces-dashboard-customization
     namespace: openshift-devspaces
     annotations:
       che.eclipse.org/mount-as: subpath
       che.eclipse.org/mount-path: /public/dashboard/assets/branding
     labels:
       app.kubernetes.io/component: devspaces-dashboard-secret
       app.kubernetes.io/part-of: che.eclipse.org
   data:
     loader.svg: <Base64_encoded_content_of_the_image> 1
   type: Opaque
   EOF

   1

   行の折り返しが無効になっている Base64 エンコーディング。

2. devspaces-dashboard のロールアウトが完了するまで待ちます。
