Extraia uma imagem de um projeto do Harbor no cliente Docker para baixar a
imagem de contêiner especificada do registro do Harbor para sua máquina local. Isso permite executar o aplicativo em contêiner localmente ou usá-lo como uma imagem de base para criar outras imagens.
Antes de começar
Para extrair uma imagem com o Docker, você precisa ter acesso ao seguinte:
O papel de identidade e acesso necessário. Peça ao administrador do IAM da organização para conceder a você o papel de Leitor de instâncias do Harbor (harbor-instance-viewer).
INSTANCE_URL: o URL da instância do Harbor. Por exemplo, harbor-1.org-1.zone1.google.gdc.test. é possível acessar o URL da instância do Harbor usando o console do GDC ou a CLI gdcloud.
HARBOR_PROJECT_NAME: o nome do projeto do Harbor. Por exemplo, my-project.
IMAGE: o nome da imagem. Por exemplo, nginx.
TAG: a tag da versão de imagem que você quer extrair. Por exemplo, staging.
IMAGE_DIGEST: o valor de hash sha256 do conteúdo da imagem. Cada versão de uma imagem tem um resumo de imagem exclusivo. Na UI da instância do Harbor, clique na imagem específica para ver o resumo dela. Para mais informações, consulte
Ver instâncias do registro do Harbor.

This\nlets you run the containerized application locally or use it as a base\nimage for building other images.\n\nBefore you begin\n----------------\n\nTo pull an image with Docker, you must have access to the following:\n\n- The necessary identity and access role. Ask your Organization IAM Admin to grant you the Harbor Instance Viewer (`harbor-instance-viewer`) role.\n- An account with the `Limited Guest` role from Harbor's role-based access controls. For more information, see [Configure access for APIs and within a Harbor instance](/distributed-cloud/hosted/docs/latest/appliance/platform-application/pa-ao-operations/configure-access-control#configure-access-within-harbor-instance).\n- An existing Harbor project. For more information, see [Create Harbor projects](/distributed-cloud/hosted/docs/latest/appliance/platform-application/pa-ao-operations/create-harbor-projects).\n- An existing container image in the existing Harbor project.\n\nPull an image\n-------------\n\nFollow these steps to pull an image from a\nHarbor project in the Docker client:\n\n1. Make sure that you are [authenticated](/distributed-cloud/hosted/docs/latest/appliance/platform-application/pa-ao-operations/configure-docker-authentication) to the Harbor instance.\n2. Pull the image from a Harbor project:\n\n docker pull \u003cvar translate=\"no\"\u003eINSTANCE_URL\u003c/var\u003e/\u003cvar translate=\"no\"\u003eHARBOR_PROJECT_NAME\u003c/var\u003e/\u003cvar translate=\"no\"\u003eIMAGE\u003c/var\u003e:\u003cvar translate=\"no\"\u003eTAG\u003c/var\u003e\n\n or \n\n docker pull \u003cvar translate=\"no\"\u003eINSTANCE_URL\u003c/var\u003e/\u003cvar translate=\"no\"\u003eHARBOR_PROJECT_NAME\u003c/var\u003e/\u003cvar translate=\"no\"\u003eIMAGE\u003c/var\u003e@\u003cvar translate=\"no\"\u003eIMAGE_DIGEST\u003c/var\u003e\n\nReplace the following values:\n\n- \u003cvar translate=\"no\"\u003eINSTANCE_URL\u003c/var\u003e: the URL of the Harbor instance. For example, `harbor-1.org-1.zone1.google.gdc.test.` You can get the URL of the Harbor instance using the [GDC console or gdcloud CLI](/distributed-cloud/hosted/docs/latest/appliance/platform-application/pa-ao-operations/manage-harbor-instances#view-harbor-registry-instances).\n- \u003cvar translate=\"no\"\u003eHARBOR_PROJECT_NAME\u003c/var\u003e: the name of the Harbor project. For example, `my-project`.\n- \u003cvar translate=\"no\"\u003eIMAGE\u003c/var\u003e: the image's name. For example, `nginx`.\n- \u003cvar translate=\"no\"\u003eTAG\u003c/var\u003e: the tag for the image version that you want to pull. For example, `staging`.\n- \u003cvar translate=\"no\"\u003eIMAGE_DIGEST\u003c/var\u003e: the sha256 hash value of the image contents. Each version of an image has a unique image digest. In the Harbor instance UI, click the specific image to see its digest.
