Fixes #771, not by introducing
tini
, but by ensuring we don't letsh
be the init process which in turn runsjupyter lab
without propegating SIGTERM to it.There may be a point to introduce
tini
or similar, but from the SIGTERM perspective, this does the trick as well.This PR is modelled on for example https://github.com/rocker-org/rocker-versioned2/pull/740/files where I see that all Dockerfiles are updated along with a repsective .json file.
