Per fare ci\u00f2, utilizza il comando `docker push`:\n\n```\n$ docker push localhost:5000\/helloworld:latest\n```\n\nIl comando `push` carica i tuoi oggetti immagine in un registro, consentendo ad altri di estrarli. Il formato del comando \u00e8 `docker push \/:`.\n\nIn questo esempio, il repository \u00e8 `localhost:5000`, il nome \u00e8 `helloworld` e il tag \u00e8 `latest`. Il repository `localhost:5000` \u00e8 il registro che abbiamo creato in precedenza. Il nome `helloworld` \u00e8 il nome dell'immagine che abbiamo creato. Il tag `latest` \u00e8 il tag che abbiamo applicato all'immagine.\n\nDopo aver eseguito il comando, dovresti vedere un output simile a questo:\n\n```\nThe push refers to a repository [localhost:5000\/helloworld] (len: 1)\n6e7a4c32b8ce: Image already exists\nc4561482baaa: Image already exists\nb6144e1b2910: Image already exists\nlatest: digest: sha256:4b1386db8e3f1f1f8c9aa1e3e7a7e7a7e7a7e7a7e7a7e7a7e7a7e7a7e7a7e7a7 size: 2422\n```\n\nQuesto output indica che l'immagine \u00e8 stata caricata con successo nel registro.<\/h3>\n
