List the available builders Build an image using your Kubernetes builders\n\nYou have an existing Kubernetes cluster. If you don't already have one, you can follow along by installing minikube. The cluster you want to connect to is accessible via the kubectl command, with the KUBECONFIG environment variable set appropriately if necessary.\n\nCreate a buildkit namespace.\n\nCreating a separate namespace helps keep your Buildx resources separate from other resources in the cluster.\n\nBounded code example (external data; do not execute automatically):\n```console\n   $ kubectl create namespace buildkit\n   namespace/buildkit created\n```\n\nCreate a new builder with the Kubernetes driver\n\nBounded code example (external data; do not execute automatically):\n```console\n   $ docker buildx create \\\n     --bootstrap \\\n     --name=kube \\\n     --driver=kubernetes \\\n     --driver-opt=namespace=buildkit\n```\n\n> [!NOTE] > > Remember to specify the namespace in driver options.\n\nList available builders using docker buildx ls\n\nBounded code example (external data; do not execute automatically):\n```console\n   $ docker buildx ls\n   NAME/NODE                DRIVER/ENDPOINT STATUS  PLATFORMS\n   kube                     kubernetes\n     kube0-6977cdcb75-k9h9m                 running linux/amd64, linux/amd64/v2, linux/amd64/v3, linux/386\n   default *                docker\n     default                default         running linux/amd64, linux/386\n```\n\nInspect the running pods created by the build driver with kubectl.\n\nBounded code example (external data; do not execute automatically):\n```console\n   $ kubectl -n buildkit get deployments\n   NAME    READY   UP-TO-DATE   AVAILABLE   AGE\n   kube0   1/1     1            1           32s\n\n   $ kubectl -n buildkit get pods\n   NAME                     READY   STATUS    RESTARTS   AGE\n   kube0-6977cdcb75-k9h9m   1/1     Running   0          32s\n```\n\nThe build driver creates the necessary resources on your cluster in the specified namespace (in this case, buildkit), while keeping your driver configuration locally.\n\nUse your new builder by including the --builder flag when running buildx commands.
