docker-compose ferma<\/code> is as follows:<\/p>\ndocker-compose ferma<\/code><\/pre>\ndocker-compose.yml<\/code> and remove the associated containers and networks. However, unless you specify --volumes<\/code>, I dati persistenti nei volumi rimangono intatti.<\/p>\nIntroduzione

Vantaggi dell'utilizzo dei volumi\n\nI volumi offrono diversi vantaggi rispetto ai bind mount:\n\n- I volumi sono pi\u00f9 facili da eseguire il backup o la migrazione.\n- \u00c8 possibile gestire i volumi utilizzando le API Docker CLI o Docker API.\n- I volumi funzionano su container Windows e Linux.\n- I volumi possono essere pi\u00f9 sicuri da condividere tra pi\u00f9 container.\n- I volumi consentono di memorizzare i dati in remoto e di eseguire il thin provisioning.\n- I volumi consentono di memorizzare i dati su cloud o provider di archiviazione remoti.\n- I volumi consentono di crittografare i dati del volume.\n- I volumi consentono di gestire nuove funzionalit\u00e0 di driver di volume senza aggiornare le applicazioni.\n\nInoltre, i volumi sono spesso una scelta migliore rispetto ai bind mount per i seguenti motivi:\n\n- I volumi sono il modo preferito per persistere i dati nei container Docker.\n- I volumi sono completamente gestiti da Docker.\n- I volumi non aumentano le dimensioni del container che li utilizza.\n- I contenuti di un volume esistono al di fuori del ciclo di vita del container, quindi Docker non li elimina automaticamente quando si rimuove il container.<\/h3>\n
