podman-kube-apply - Apply Kubernetes YAML based on containers, pods, or volumes to a Kubernetes cluster
Contents
Description
podmankubeapply 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).
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

Options
--ca-cert-file=cacertfilepath|insecure
The path to the CA cert file for the Kubernetes cluster. Usually the kubeconfig has the CA cert file data
and generatekube 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=kubeyamlfilepath
Path to the kubernetes yaml file to deploy onto the kubernetes cluster. This file can be generated using
the podmankubegenerate command. The input may be in the form of a yaml file, or stdin. For stdin, use
--file=-.
--kubeconfig,-k=kubeconfigfilepath
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 kubegenerate 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.
