Get YAML for deployed Kubernetes services?

I am trying to deploy my app to Kubernetes running in Google Container Engine.

The app can be found at: https://github.com/Industrial/docker-znc.

The Dockerfile is built into an image on Google Container Registry.

I have deployed the app in Kubernetes via the + button. I don't have the YAML for this.

I have inserted a Secret in Kubernetes for the PEM file required by the app.

1. How do I get the YAML for the Deployment, Service and Pod created by Kubernetes by filling in the form?
2. How do I get the Secret into my Pod for usage?

Solution 1:

To get the yaml for a deployment (service, pod, secret, etc):

kubectl get deploy deploymentname -o yaml

Solution 2:

How do I get the YAML for the Deployment, Service and Pod created by Kubernetes by filling in the form?

kubectl get deployment,service,pod yourapp -o yaml --export

Answering @Sinaesthetic question:

any idea how to do it for the full cluster (all deployments)?

kubectl get deploy --all-namespaces -o yaml --export

The problem with this method is that export doesn't include the namespace. So if you want to export many resources at the same time, I recommend doing it per namespace:

kubectl get deploy,sts,svc,configmap,secret -n default -o yaml --export > default.yaml

Unfortunately kubernetes still doesn't support a true get all command, so you need to list manually the type of resources you want to export. You can get a list of resource types with

kubectl api-resources
