how to set more memory to `theia-ide` container?

[Divine1]

Summary

while running mvn clean install command , the theia-ide container shows 477 /512 in memory. sometimes it increases to 499/512 . How to increase the memory for theia-ide to 800mb?

The cpu metric for some reason is a 10digit number. For theia-ide it shows 9632217000m/1500m . what does 9632217000m and 1500m represent ?

Hi @Divine1 , for increasing the memory limit for the theia-ide container you can:

• You can manually update the memoryLimit for the theia-ide container definition in the editor's DevWorkspaceTemplate for your workspace, and then restart your workspace. For your case, you should be able to find a DevWorkspaceTemplate resource named theia-ide-cbfsel-repo7 in your cluster

• Or, you're supposed to be able to create a .che/che-editor.yaml file in your repository with the following content. (However there is a bug: https://github.com/eclipse/che/issues/21639, so this method will not work at the moment):

id: eclipse/che-theia/next      # you can choose whatever theia editor ID here
override:
  containers:
    - name: theia-ide
      memoryLimit: 800Mi

Here are some related docs: https://www.eclipse.org/che/docs/stable/end-user-guide/specifying-an-in-browser-ide-for-a-git-repository-by-using-che-editor.yaml/#using-a-custom-plug-in-registry-for-your-ide_che

@dkwon17

there will be multiple users using the workspace. So i cannot manually go into the namespace and update the DevWorkspaceTemple for each workspace. please let me know if there are any alternate solutions

[azatsarynnyy]

It's also possible to pass an editor Devfile through the URL che-editor parameter. However, I'm not sure if it's a suitable solution for your use case @Divine1. Likely, deploying a custom plugin registry (that @dkwon17 has mentioned above) is the only solution here, considering providing .che/che-editor.yaml doesn't currently work as expected.

To complement @azatsarynnyy suggestion: you need to publish your customized Theia definition as a devfile.yaml somewhere accessible from your browser and point it from the URL to start your workspace like https://<che_fqdn>#<git_repository_url>?che-editor=<editor_devfile_yaml_url>. As a reference here is the current definition of Theia (https://eclipse-che.github.io/che-plugin-registry/main/v3/plugins/eclipse/che-theia/latest/devfile.yaml).

@svor is it a bug in the Resource Monitor plugin?

@azatsarynnyy

you need to publish your customized Theia definition as a devfile.yaml please provide a sample devfile.yaml

Also, let me know where should i add the devfile.yaml configuration.

currently i use below devfile.yaml. my chectl version is chectl/0.0.20220809-next.c9f4ba1 darwin-x64 node-v16.13.2

Also, let me know where should i add the devfile.yaml configuration.

@Divine1 the editor's Devfile can be placed on GitHub gist, for example.

@azatsarynnyy

you need to publish your customized Theia definition as a devfile.yaml

i want to know the contents of the Theia definition devfile.yaml. And should i add the link to the Theia definition devfile.yaml in che-operator-cr-patch.yaml?

[azatsarynnyy]

i want to know the contents of the Theia definition devfile.yaml.

@Divine1 see the latest comment by Mario, above https://github.com/eclipse/che/issues/21683#issuecomment-1236677041 There's a link to Che-Theia Devfile. You can copy and modify it as you need.

And should i add the link to the Theia definition devfile.yaml in che-operator-cr-patch.yaml?

no. As it's said in Mario's comment, the editor's Devfile link should be provided to the ?che-editor= parameter in URL

[Divine1]

@azatsarynnyy i will try this and share the feedback
