Error building latest Docker image on Ubuntu

[nexxus-vi]

• Errbit version: errbit/errbit:latest
• OS: ubuntu 16.04.02 LTS

Describe the problem:

I can't build latest Docker image on ubuntu, on macos it works fine. Image before latest can build and run

Steps to reproduce:

1. Run docker-compose up --build

Observed Results:

• errbit_1 | bundler: command not found: puma
  errbit_1 | Install missing gem executables with bundle install
  errbit_errbit_1 exited with code 127

Expected Results:

• Image up

Application Logs:

• bundler: command not found: puma

errbit:v0.9.0 works fine.

I don't see an issue yet. Can you grab the latest from github and paste the output of docker build .?

Stange. You can see that it does work as GitHub does the build for us:

I wonder if there's something about the way your docker daemon is configured. Maybe this test could shed some light. When I run commands against the base image, I am root (within the container), and I am able to write to /root. Are you?

~/d/e/errbit (main)> docker run --rm -it ruby:2.7.6-alpine whoami
root
~/d/e/errbit (main)> docker run --rm -it ruby:2.7.6-alpine touch /root/foo

[nexxus-vi]

Yes, it seems like I am (g)root

(base) user@host:~$   docker run --rm -it ruby:2.7.6-alpine whoami
root
(base) user@host:~$  docker run --rm -it ruby:2.7.6-alpine touch /root/foo
(base) user@host:~$

That's really odd. Right there on step 6, it says /root is not writable. Can you run that specific container and debug it?
docker run --rm -it cef1e71b45e1 sh

From there you should be able to run step 6 manually and hopefully figure out what's up.

[stevecrozz]

Any ideas + @pigri ?

[nexxus-vi]

Nope, that container does not exist. If I try to run the command on the container from step 5 I get the same error /root is not writable... but i can manually write to it!

[stevecrozz]

Can you break it down to find the first part of the command that gives you an error? It looks like we'll have to debug that in particular

[nexxus-vi]

/app # /bin/sh -c echo "gem: --no-document"

/app # /bin/sh -c echo "gem: --no-document" >> /etc/gemrc
/app # /bin/sh -c echo "gem: --no-document" >> /etc/gemrc   && bundle config --global frozen 1
`/root` is not writable.
Bundler will use `/tmp/bundler20221107-8-qvs6hm8' as your home directory temporarily.

Bundle config is the issue
