Use of extensions?

[hugoideler]

Hi, thanks for creating the flatpak!

Has the flatpak also been tested with extensions? In particular, @alebcay/openlens-node-pod-menu?

I am finding that the installation of the extension is not successful. On the other hand, I've also tried an OpenLens AppImage, and there it works.

The error I get is:

info:    ▪ [EXTENSION-INSTALLER] installing package from /home/myusername/.k8slens/extensions/alebcay--openlens-node-pod-menu to /home/myusername/.var/app/dev.k8slens.OpenLens/config/OpenLens +7s

I've also tried giving the flatpak permissions to my home folder, but that made no difference.

Same here, installing extensions does not work.

Same here. I did manage to install the extension manually :
I retrieved the openlens-node-pod-menu-0.1.2.tgz archive from /run/user/<UID>/app/dev.k8slens.OpenLens/lens-extensions/, extracted it manually and put the content of the package subfolder in /home/<username>/.var/app/dev.k8slens.OpenLens/config/OpenLens/node_modules/@alebcay/openlens-node-pod-menu/. After a restart of the app the extension works.

The packaged binaries e.g. kubectl are not accessible under the PATH variable (at least the integrated shell suggests that). Could be that ENOENT (a.k.a. "No such file or directory") means that one of those executables is not found.

In my case I had to manually install it. I am new to Flatpak so I leave this to others to fix.

cd /var/lib/flatpak/app/dev.k8slens.OpenLens/current/active/files/bin
curl -LO "https://dl.k8s.io/release/$(curl -L -s https://dl.k8s.io/release/stable.txt)/bin/linux/amd64/kubectl"

Hi, I am experiencing the same issue as @hugoideler with several extensions – in my case using latest OpenLens 6.5.2 with Node.js 16.17.1.

It seems that the extensions' npm dependencies are unresolved, as the respective directory is empty:

~/.var/app/dev.k8slens.OpenLens/config/OpenLens/node_modules

Maybe we'd need to run npm install manually after adding a new extension? 😺

Just in case, here is an example stacktrace for an extension that is not working:

[EXTENSIONS-LOADER]: can't load renderer for "lens-extension-network-policy-viewer": Error: Cannot find module '/home/redtux/.var/app/dev.k8slens.OpenLens/config/OpenLens/node_modules/lens-extension-network-policy-viewer/dist/renderer.js'

I verified that the extension was correctly downloaded btw:
