Dengan mengikuti langkah-langkah ini, Anda memastikan bahwa hanya image tepercaya dan terverifikasi yang digunakan untuk membuat container Kubernetes di cluster GKE Anda. Hal ini membantu
mempertahankan lingkungan yang aman untuk aplikasi Anda.
Mengonfigurasi kebijakan
Mengaktifkan Otorisasi Biner saja tidak akan otomatis melindungi cluster Anda.
Secara default, semua image container dapat di-deploy jika tidak ada kebijakan yang dikonfigurasi. Artinya, untuk mengamankan cluster secara efektif, Anda perlu
menentukan dan menerapkan kebijakan yang menentukan image mana yang diizinkan. Untuk
mempelajari cara mengonfigurasi kebijakan Otorisasi Biner, lihat
Mengonfigurasi kebijakan menggunakan Google Cloud CLI.

The required permissions are now automatically granted to this service account. You can therefore disregard step 2 in the following instructions.\n\nTo enable Binary Authorization for GKE attached clusters, perform the following steps:\n\n1. Enable the Binary Authorization API in your project:\n\n gcloud services enable binaryauthorization.googleapis.com \\\n --project=\u003cvar translate=\"no\"\u003ePROJECT_ID\u003c/var\u003e\n\n Replace \u003cvar translate=\"no\"\u003ePROJECT_ID\u003c/var\u003e with the ID of your\n Google Cloud project.\n2. Grant the `binaryauthorization.policyEvaluator` role to the Kubernetes\n service account associated with the Binary Authorization agent:\n\n gcloud projects add-iam-policy-binding \u003cvar translate=\"no\"\u003ePROJECT_ID\u003c/var\u003e \\\n --member=serviceAccount:\u003cvar translate=\"no\"\u003ePROJECT_ID\u003c/var\u003e.svc.id.goog[gke-system/binauthz-agent] \\\n --role=\"roles/binaryauthorization.policyEvaluator\"\n\n3. Enable Binary Authorization when registering or updating a cluster.\n\n ### Register a cluster\n\n To enable Binary Authorization when registering a cluster, use the\n [`gcloud container attached clusters register` command](/sdk/gcloud/reference/container/attached/clusters/register). Follow the instructions in\n [attach your EKS cluster](/kubernetes-engine/multi-cloud/docs/attached/eks/how-to/attach-cluster),\n and include the optional argument\n `--binauthz-evaluation-mode=PROJECT_SINGLETON_POLICY_ENFORCE`: \n\n gcloud container attached clusters register \u003cvar translate=\"no\"\u003eCLUSTER_NAME\u003c/var\u003e \\\n ...\n --binauthz-evaluation-mode=PROJECT_SINGLETON_POLICY_ENFORCE\n\n Replace \u003cvar translate=\"no\"\u003eCLUSTER_NAME\u003c/var\u003e with the name of\n your cluster.\n\n ### Update a cluster\n\n To enable Binary Authorization when updating a cluster, use the\n [`gcloud container attached clusters update` command](/sdk/gcloud/reference/container/attached/clusters/update). Follow the instructions in\n [update your EKS cluster](/kubernetes-engine/multi-cloud/docs/attached/eks/how-to/update-cluster),\n and include the optional argument\n `--binauthz-evaluation-mode=PROJECT_SINGLETON_POLICY_ENFORCE`: \n\n gcloud container attached clusters update \u003cvar translate=\"no\"\u003eCLUSTER_NAME\u003c/var\u003e \\\n ...\n --binauthz-evaluation-mode=PROJECT_SINGLETON_POLICY_ENFORCE\n\n Replace \u003cvar translate=\"no\"\u003eCLUSTER_NAME\u003c/var\u003e with the name of\n your cluster.\n\nBy following these steps, you ensure that only trusted and verified images\nare used to create Kubernetes containers in your GKE clusters. This helps\nto maintain a secure environment for your applications.\n\nConfigure policies\n------------------\n\nEnabling Binary Authorization alone doesn't automatically protect your cluster.\nBy default, it allows all container images to be deployed if no policy is\nconfigured. This means that to effectively secure your cluster, you need to\ndefine and enforce a policy that specifies which images are allowed. To\nlearn how to configure a Binary Authorization policy, see\n[Configure a policy using the Google Cloud CLI](/binary-authorization/docs/configuring-policy-cli)."]]
