podman-kube-apply(1)

NAME
podman-kube-apply - Apply Kubernetes YAML based on containers, pods, or volumes to a Kubernetes cluster

SYNOPSIS
podman kube apply [options] [container... | pod... | volume...]

DESCRIPTION
podman kube apply deploys a podman container, pod, or volume to a Kubernetes cluster. Use the --file option to deploy a Kubernetes YAML (v1 specification) to a Kubernetes cluster as well.

Note that the Kubernetes YAML file can be used to run the deployment in Podman via podman-play-kube(1).

OPTIONS

  --ca-cert-file=ca cert file path | insecure
The path to the CA cert file for the Kubernetes cluster. Usually the kubeconfig has the CA cert file data and generate kube automatically picks that up if it is available in the kubeconfig. If no CA cert file data is available, set this to insecure to bypass the certificate verification.

  --file, -f=kube yaml filepath
Path to the kubernetes yaml file to deploy onto the kubernetes cluster. This file can be generated using the podman kube generate command. The input may be in the form of a yaml file, or stdin. For stdin, use --file=-.

  --kubeconfig, -k=kubeconfig filepath
Path to the kubeconfig file to be used when deploying the generated kube yaml to the Kubernetes cluster. The environment variable KUBECONFIG can be used to set the path for the kubeconfig file as well. Note: A kubeconfig can have multiple cluster configurations, but kube generate always picks the first cluster configuration in the given kubeconfig.

  --ns=namespace
The namespace or project to deploy the workloads of the generated kube yaml to in the Kubernetes cluster.

  --service, -s
Used to create a service for the corresponding container or pod being deployed to the cluster. In particular, if the container or pod has portmap bindings, the service specification includes a NodePort declaration to expose the service. A random port is assigned by Podman in the service specification that is deployed to the cluster.

EXAMPLES
Apply a podman volume and container to the "default" namespace in a Kubernetes cluster.
    $ podman kube apply --kubeconfig /tmp/kubeconfig myvol vol-test-1
    Deploying to cluster...
    Successfully deployed workloads to cluster!
    $ kubectl get pods
    NAME             READY   STATUS    RESTARTS   AGE
    vol-test-1-pod   1/1     Running   0          9m

Apply a Kubernetes YAML file to the "default" namespace in a Kubernetes cluster.
    $ podman kube apply --kubeconfig /tmp/kubeconfig -f vol.yaml
    Deploying to cluster...
    Successfully deployed workloads to cluster!
    $ kubectl get pods
    NAME             READY   STATUS    RESTARTS   AGE
    vol-test-2-pod   1/1     Running   0          9m

Apply a Kubernetes YAML file to the "test1" namespace in a Kubernetes cluster.
    $ podman kube apply --kubeconfig /tmp/kubeconfig --ns test1 vol-test-3
    Deploying to cluster...
    Successfully deployed workloads to cluster!
    $ kubectl get pods --namespace test1
    NAME             READY   STATUS    RESTARTS   AGE
    vol-test-3-pod   1/1     Running   0          9m
