How to edit a file in a running pod?

[Stephen Wicklund]

I am able to view the file-tree of running pods, and view the file contents, but how can I edit those files?

[Stephen Wicklund]

Nevermind, I figured it out:

1. Right-click the remote file you want to edit, press "kubectl copy from", and save it somewhere on your local computer. (alternatively, you can right-click and press "View file", then copy-paste it into a local file)
2. Edit that local copy of the file.
3. Right click the folder parent of the original remote file, press "kubectl copy to from file", and select your edited local copy of the file.

However, there were three snags I hit with the above:

1. The "kubectl copy from" command did not work for me at first, because the terminal I had open was already running a task; there should be a warning message that for the "kubectl" commands to work, the currently open terminal tab must be non-busy/accepting-commands.
2. The "kubectl copy from" command failed even after opening a fresh terminal tab; this is because the cd \D [...] command it uses only works for CMD, not Powershell (the default, for me at least). In Powershell, the \D argument apparently needs to be removed.
3. The "kubectl" commands failed for me even after the above, because the path it was copying to had spaces in it; when I manually reran the command with quotes added around the path, it succeeded.

Would you be open to pull-requests to fix these issues?

This feature would be a very useful addition to this extension.

I've made a PR for exactly your requirements, hope it may gets merged :-)

Unfortunately the PR was rejected without a reason, so I decided to fork it and created an own extension with editing functionality. It now also includes favorite files for quicker access (in beta):
