Unable to edit configmap in kubernetes

Question

I have a already running kubernetes application(eclipse che) I am editing a configmap with the following command kubectl edit cm/che -n che When I edit and save it, I get a message saying that the configmap is saved. But when I again issue the same command I cannot find my changes. Am I missing some basic step?

Answer 1

In case you deployed devfile registry with helm and you only need only your devfile registry and not the one provided by che try the following -

1. Remove the helm chart by helm delete che-devfile-registry -n che

2. kubectl edit checluster eclipse-che -n che

3. Add devfileRegistryImage: 'Your devfile Image' under spec: server:

4. Save

After that go to the default che url you should be able to see your custom stack in the list.

Answer 2

use kubectl verbose mode for tracing the problem

kubectl edit cm/che -n che -v9

I guess it could be related to permissions, admission controls, or operator frameworks.

Answer 3

If you have installed Che with operator (through chectl or not), you should change the settings editing the CheCluster custom resource:

kubectl edit CheCluster/eclipse-che -n che
