Il 15 settembre 2026, tutti gli ambienti Cloud Composer 1 e Cloud Composer 2 versione 2.0.x raggiungeranno la fine del ciclo di vita pianificata e non potrai più utilizzarli. Ti consigliamo di pianificare la migrazione a Cloud Composer 3.
Questa pagina descrive come installare plug-in personalizzati nel tuo ambiente Cloud Composer.
Il gestore dei plug-in di Apache Airflow ti consente di scrivere operatori, hook, sensori o interfacce Apache Airflow personalizzati interni.
Per saperne di più, consulta la sezione Plug-in personalizzati
nella documentazione di Airflow.
Informazioni sui plug-in personalizzati
Quando crei un ambiente, Cloud Composer crea un bucket Cloud Storage e lo associa al tuo ambiente. Utilizza la cartella plugins nel bucket del tuo
ambiente per installare plug-in personalizzati.
Prima di iniziare
Il tuo account deve avere un ruolo che consenta di visualizzare e
modificare i contenuti del bucket del tuo ambiente.
Questo metodo di installazione si applica solo ai
plug-in Airflow. Ad esempio, non puoi utilizzare questo metodo per installare moduli Python comuni o altre librerie.
LOCATION con la regione in cui si trova l'ambiente.
PATH_TO_LOCAL_FILE con il percorso del file da caricare.
(Facoltativo) PATH_IN_SUBFOLDER con il percorso della sottocartella. Utilizza
l'argomento --destination per caricare un plug-in in una sottocartella della
cartella plugins. In caso contrario, ometti l'argomento --destination.
Visualizzare l'elenco dei plug-in
Console
Nella console Google Cloud , vai alla pagina Ambienti.
LOCATION con la regione in cui si trova l'ambiente.
PATH_TO_LOCAL_DESTINATION con la destinazione del file scaricato.
(Facoltativo) --source è un'opzione per scaricare un solo plug-in.
PATH_IN_FOLDER è il percorso della cartella.
Disattivare i plug-in del server web
In Cloud Composer 3, se riscontri problemi con l'interfaccia utente di Airflow, puoi disattivare i plug-in del server web senza doverli rimuovere dal bucket dell'ambiente.
gcloud
I seguenti argomenti di Google Cloud CLI disattivano e attivano i plug-in del server web:
--no-support-web-server-plugins: disattiva i plug-in dei server web
--support-web-server-plugins: attiva i plug-in per server web
Per disattivare i plug-in del server web, esegui questo comando
Google Cloud CLI:
Un plug-in appena caricato non è visibile nella UI di Airflow
Se utilizzi il controllo dell'accesso alla UI di Airflow, il plug-in appena caricato potrebbe non essere visibile nella UI di Airflow. Per risolvere il problema, chiedi
all'amministratore dell'interfaccia utente di Airflow di configurare l'accesso al plug-in appena caricato o
assegnati il ruolo Admin nell'interfaccia utente di Airflow.

You use the `plugins` folder in your\nenvironment's bucket to install custom plugins.\n\nBefore you begin\n\n- Your account [must have a role](/composer/docs/composer-3/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\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\nConsole\n\n1.
