Le 15 septembre 2026, tous les environnements Cloud Composer 1 et Cloud Composer 2 version 2.0.x atteindront leur fin de vie prévue et vous ne pourrez plus les utiliser. Nous vous recommandons de planifier la migration vers Cloud Composer 3.
Remplacer les options de configuration Airflow pour de nouveaux environnements
Vous pouvez remplacer les options de configuration Airflow lorsque vous créez votre environnement. Pour en savoir plus, consultez la page Créer des environnements.
Remplacer les options de configuration Airflow pour les environnements existants
Pour remplacer tous les remplacements de configuration Airflow existants par les options spécifiées, spécifiez le masque config.softwareConfig.airflowConfigOverrides dans le paramètre updateMask.
Pour remplacer une option de configuration Airflow spécifique, dans le paramètre updateMask, spécifiez le masque config.softwareConfig.airflowConfigOverrides.KEY. Remplacez KEY par la section de configuration et le nom de l'option séparés par un trait d'union (par exemple, webserver-dag_orientation).
Si vous souhaitez remplacer plusieurs options de configuration Airflow, spécifiez plusieurs masques séparés par des virgules dans le paramètre updateMask.
Le corps de la requête doit contenir la liste des options de configuration Airflow.
Si vous remplacez tous les forçages existants, veillez à inclure tous les forçages que vous souhaitez conserver.

By doing so you can adjust the Airflow instance to your\nneeds and requirements.\n| **Note:** some Airflow configuration options are [blocked](/composer/docs/airflow-configurations) and you cannot override them.\n\nOverride Airflow configuration options for new environments\n\nYou can override Airflow configuration options when you create your\nenvironment. For more information, see\n[Create environments](/composer/docs/composer-1/create-environments#overrides-env-vars).\n\nOverride Airflow configuration options for existing environments \n\nConsole\n\nTo override [Airflow configuration options](https://airflow.apache.org/docs/apache-airflow/stable/configurations-ref.html) for an\nexisting environment:\n\n1. In Google Cloud console, go to the **Environments** page.\n\n [Go to Environments](https://console.cloud.google.com/composer/environments)\n2. In the list of environments, click the name of your environment.\n The **Environment details page opens**.\n\n3. Go to the **Airflow configuration overrides** tab.\n\n4. Click **Edit**.\n\n5. Enter the **Section** , **Key** , and **Value** for the Airflow\n configuration option that you want to change.\n\nFor example:\n\n| Section | Key | Value |\n|-------------|-------------------|-------|\n| `webserver` | `dag_orientation` | `RL` |\n\ngcloud\n\nFollowing arguments override\n[Airflow configuration options](https://airflow.apache.org/docs/apache-airflow/stable/configurations-ref.html) for an existing\nenvironment:\n\n- `--update-airflow-configs` adds or changes specified Airflow configuration overrides.\n- `--remove-airflow-configs` removes specified Airflow configuration overrides.\n- `--clear-airflow-configs` removes all Airflow configuration overrides.\n\n gcloud composer environments update \u003cvar translate=\"no\"\u003eENVIRONMENT_NAME\u003c/var\u003e \\\n --location \u003cvar translate=\"no\"\u003eLOCATION\u003c/var\u003e \\\n --update-airflow-configs=\u003cvar translate=\"no\"\u003e\u003cspan class=\"devsite-syntax-nv\"\u003eKEY\u003c/span\u003e\u003cspan class=\"devsite-syntax-o\"\u003e=\u003c/span\u003eVALUE,KEY\u003cspan class=\"devsite-syntax-o\"\u003e=\u003c/span\u003eVALUE,...\u003c/var\u003e\n\nReplace:\n\n- `ENVIRONMENT_NAME` with the name of the environment.\n- `LOCATION` with the region where the environment is located.\n- `KEY` with the configuration section and the option name separated by a hyphen, for example, `webserver-dag_orientation`.\n- `VALUE` with the corresponding value for an option.\n\nFor example: \n\n gcloud composer environments update example-environment \\\n --location us-central1 \\\n --update-airflow-configs=webserver-dag_default_view=graph,webserver-dag_orientation=RL\n\nAPI\n\nTo override [Airflow configuration options](https://airflow.apache.org/docs/apache-airflow/stable/configurations-ref.html) for an\nexisting environment:\n\n1. Construct an [`environments.patch`](/composer/docs/reference/rest/v1/projects.locations.environments/patch) API request.\n\n2. In this request:\n\n - To replace all existing Airflow configuration overrides with\n the specified options, in the `updateMask` parameter, specify\n the `config.softwareConfig.airflowConfigOverrides` mask.\n\n - To override a specific Airflow configuration option, in\n the `updateMask` parameter, specify\n the `config.softwareConfig.airflowConfigOverrides.`\u003cvar translate=\"no\"\u003eKEY\u003c/var\u003e\n mask. Replace `KEY` with the configuration section and the option\n name separated by a hyphen, for example, `webserver-dag_orientation`.\n\n If you want to override several Airflow configuration options, in\n the `updateMask` parameter, specify several masks separated by commas.\n3. The request body must contain the list of Airflow configuration options.\n If you are replacing all existing overrides, make sure to include all\n overrides that you want to keep.\n\n {\n \"config\": {\n \"softwareConfig\": {\n \"airflowConfigOverrides\": {\n \"\u003cvar translate=\"no\"\u003eKEY\u003c/var\u003e\": \"\u003cvar translate=\"no\"\u003eVALUE\u003c/var\u003e\"\n }\n }\n }\n }\n\nReplace:\n\n- `KEY` with the configuration section and the option name separated by a hyphen, for example, `webserver-dag_orientation`.\n- `VALUE` with the corresponding value for an option.\n\nThe following example overrides two specific Airflow configuration options: \n\n // PATCH https://composer.googleapis.com/v1/projects/example-project/\n // locations/us-central1/environments/example-environment?updateMask=\n // config.softwareConfig.airflowConfigOverrides.webserver-dag_default_view,\n // config.softwareConfig.airflowConfigOverrides.webserver-dag_orientation\n\n {\n \"config\": {\n \"softwareConfig\": {\n \"airflowConfigOverrides\": {\n \"webserver-dag_default_view\": \"graph\",\n \"webserver-dag_orientation\": \"RL\"\n }\n }\n }\n }\n\nTerraform\n\nThe `airflow_config_overrides` block in the `software_config` block\ncontrols overrides of [Airflow configuration options](https://airflow.apache.org/docs/apache-airflow/stable/configurations-ref.html)\nfor your environment: \n\n resource \"google_composer_environment\" \"example\" {\n\n config {\n\n # ...
