Puoi installare componenti aggiuntivi come Docker quando crei un cluster Dataproc utilizzando la funzionalità Componenti facoltativi. Questa pagina descrive il componente Docker.
Il componente Dataproc installa un
daemon Docker
su ogni nodo del cluster e crea un utente Linux "docker" e un gruppo Linux
"docker" su ogni nodo per eseguire il daemon Docker. Questo componente crea anche
un servizio "docker" systemd
per eseguire il servizio dockerd. Devi utilizzare il servizio systemd per gestire il ciclo di vita del servizio Docker.
Installa il componente
Installa il componente quando crei un cluster Dataproc.
Il componente Docker può essere installato su cluster creati con
Dataproc immagine versione 1.5
o successive.
Per creare un cluster Dataproc che includa il componente Docker,
utilizza il comando
gcloud dataproc clusters createcluster-name
con il flag --optional-components.
Il componente Dataproc Docker configura Docker per
utilizzare Container Registry oltre ai registri Docker predefiniti.
Docker utilizzerà l'assistente per le credenziali Docker per l'autenticazione con
Container Registry.
Utilizzare il componente Docker su un cluster Kerberos
Puoi installare il componente facoltativo Docker su un cluster in fase di creazione con la sicurezza Kerberos abilitata.
