I'm trying to run remotely a kubernetes command using python and ssh. The command doesn't work if is run remote, but works if is run directly on the machine.
"kubectl get po --all-namespaces -o jsonpath='{range .items[*]}{.metadata.name}{"\t"}{.spec.containers[0].image}{"\t"}{.metadata.labels.k8s-app}{"\n"}{end}"If it runs as it is, the recive error is
"Pods [NotFound] .items[*]}"
If I replace ' with " and viceversa the eror is "-
Expecting 'EOF'
Taking in consideration that the command run on machine directly, something is interpreted when is passed remotely to the shell. I tried different combination but are not working.

As @Orion pointed in comments it seems that your command is not full. I've tested it on mine GKE cluster.
$ kubectl get po --all-namespaces -o jsonpath='{range .items[*]}{.metadata.name}{"\t"}{.spec.containers[0].
image}{"\t"}{.metadata.labels.k8s-app}{"\n"}{end}

When you used jsonpath= you started it with sign ', however you did not close it. That's why Kubernetes is still expecting some values. However, if you will end jasonpath with ' you will receive output like:
$ kubectl get po --all-namespaces -o jsonpath='{range .items[*]}{.metadata.name}{"\t"}{.spec.containers[0].
image}{"\t"}{.metadata.labels.k8s-app}{"\n"}{end}'

prometheus-to-sd-xmfsl k8s.gcr.io/prometheus-to-sd:v0.5.2 prometheus-to-sdAs you want to run exact command remotely you have to use " at beginning and the end, same with jsonpatch.
Based on information you have provided, solution for your problem should be below command:
"kubectl get po --all-namespaces -o jsonpath='{range .items[*]}{.metadata.name}{"\t"}{.spec.containers[0].image}{"\t"}{.metadata.labels.k8s-app}{"\n"}{end}'"
