what is difference with https://github.com/eclipse/che/tree/master/dockerfiles/theia ?

[ghost]

1. No ssh plugin
2. Fixed versions in full package.json
3. Script that checks package availability and replaces latest with a fixed version.

Dockerfile from Che repo will be removed. We will use this one, and tag with with Theia release, not Che.

[ghost]

I haven't made a PR to Che repo yet.

This PR in dockerfiles fixes https://github.com/eclipse/che/issues/9649

[benoitf]

I mean, where has it been discussed that it will be moved from che repo to che-dockerfiles repo ?

[ghost]

In the PR that I am about to issues against Che repository.

[benoitf]

if there is a PR it seems to me that there is already a choice that has been made by someone.

[ghost]

I have just issued a PR to Che repo.
