Plugins are not supported in Cloud Composer 1 environments with Airflow 2.\n\nAbout custom plugins\n--------------------\n\nWhen you create an environment, Cloud Composer\n[creates a Cloud Storage bucket](/composer/docs/composer-1/cloud-storage) and associates this\nbucket with your environment. You use the `plugins` folder in your\nenvironment's bucket to install custom plugins.\n\nBefore you begin\n----------------\n\n- Your account [must have a role](/composer/docs/composer-1/access-control#user-account) that allows viewing and modifying your environment's bucket contents.\n- This installation method applies only to [Airflow plugins](https://airflow.apache.org/docs/apache-airflow/stable/authoring-and-scheduling/plugins.html). For example, you cannot use this method to install common Python modules or other libraries.\n- Plugins must conform to the [Airflow plugins template](https://airflow.apache.org/docs/apache-airflow/stable/authoring-and-scheduling/plugins.html#example) guidelines.\n\nInstall a plugin\n----------------\n\nTo install a custom plugin into your Cloud Composer environment,\ncopy the plugin code to the `plugins` folder in your environment's bucket.\n| **Note:** After the plugins are loaded, they are never reloaded, except the UI plugins in the web server. You might need to restart the web server or the scheduler processes manually. Otherwise, a scheduler only restarts after the [`[scheduler]num_runs`](https://airflow.apache.org/docs/apache-airflow/stable/configurations-ref.html#num-runs), which is set to 5000 by default.\n\nTo install a plugin: \n\n### Console\n\n1. In the Google Cloud console, go to the **Environments** page.\n\n [Go to Environments](https://console.cloud.google.com/composer/environments)\n2. Find your environment and follow the **DAGs** link.\n\n3. Go one folder level up, then navigate to the `plugins/` folder.\n\n4. Upload your plugin files. For more information about uploading objects,\n see [Uploading objects](/storage/docs/uploading-objects).\n\n### gcloud\n\nUse the following `gcloud` command: \n\n gcloud composer environments storage plugins import \\\n --environment \u003cvar translate=\"no\"\u003eENVIRONMENT_NAME\u003c/var\u003e \\\n --location \u003cvar translate=\"no\"\u003eLOCATION\u003c/var\u003e \\\n --source \u003cvar translate=\"no\"\u003ePATH_TO_LOCAL_FILE\u003c/var\u003e \\\n --destination \u003cvar translate=\"no\"\u003ePATH_IN_SUBFOLDER\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- `PATH_TO_LOCAL_FILE` with the path of the file to upload.\n- (Optional) `PATH_IN_SUBFOLDER` with the subfolder path. Use the `--destination` argument to upload a plugin to a subfolder in the `plugins` folder. Otherwise, omit the `--destination` argument.\n\nView the list of plugins\n------------------------\n\n### Console\n\n1.

To address this issue, ask\nAirflow UI Administrator to configure access to the newly uploaded plugin or\nassign yourself the `Admin` role in Airflow UI.\n\nWhat's next\n-----------\n\n- [Data stored in Cloud Storage](/composer/docs/composer-1/cloud-storage)\n- [Manage DAGs](/composer/docs/composer-1/manage-dags)"]]
