trying to use onbuild with binder, error "unknown flag: chown"
Opened this issue · 6 comments
I'm trying out the new onbuild stuff in this repo:
https://github.com/rabernat/local_stencil_ml_examples
My Dockerfile looks like this
FROM pangeo/pangeo-notebook-onbuild:2019.04.19
# https://mybinder.readthedocs.io/en/latest/tutorials/dockerfile.html#preparing-your-dockerfile
ENV NB_USER jovyan
ENV NB_UID 1000
ENV HOME /home/${NB_USER}
COPY . ${HOME}
USER root
RUN chown -R ${NB_UID} ${HOME}
USER ${NB_USER}
I got this error.

I'm going to try removing all the extra docker stuff.
After updating the Dockerfile, I am still getting the same error

I think you need a newer version of docker - —chown was added a few years ago. We can also make the onbuild variants not use it if we wanna support older versions of docker. If this is on Pangeo binder I think it should be fixed by the dind work @jhamman is doing. Can you try on mybinder.org to see if it works there?
Also you only need the FROM line and nothing more when using the onbuild variants.
#37 removes --chown so the onbuild variants will be compatible with older docker versions.
I think rabernat/local_stencil_ml_examples#1 fixes it. It works on mybinder.org with this - https://mybinder.org/v2/gh/yuvipanda/local_stencil_ml_examples/master. Once #37 lands and we use that as base image, it should work on pangeo binder too.
