Piggybacking on this… what’s the quickest way to deploy a docker container in Kubernetes short of having to hand create the deployment yaml? Or is that it, having to create one from scratch.
If you run it in podman, podman can export into a kubernete file, but its been a long time since I’ve tried it though. podman kube generate $CONTAINERNAME
this just creates a pod running the specific image. If you kill the pod, or it terminates, it won’t be run again.
In general though, you probably want to do some customization before running (maybe you need volumes, secrets, env, ports, labels, securityContext, etc.) and for that you can simply let kubectl generate the boilerplate YAML and then simply make some edit:
In case you don’t need anything fancy, the kubectl create subcommand allows you to create simple workload, so probably that’s the answer to your question.

podman kube generate $CONTAINERNAME
You have a bunch of options:
kubectl run $NAME --image=$IMAGE
this just creates a pod running the specific image. If you kill the pod, or it terminates, it won’t be run again.

kubectl run $NAME --image=$IMAGE --dry-run=client -o yaml > mypod.yaml # edit mypod.yaml kubectl create -f mypod.yaml
You can do the same with a
deployment
orstatefulset
:kubectl create deployment $NAME -n $NAMESPACE [...] --dry-run=client -o yaml > deployment.yaml
In case you don’t need anything fancy, the
kubectl create
subcommand allows you to create simple workload, so probably that’s the answer to your question.You rock! Yeah I just wanted to run the image first before building out the whole framework around it. This is what I was looking for.
