Permission denied running with docker

[elalemanyo]

Hi, I am trying to replace foreman with overmind. All my dev setup is running with Docker evilmartians/ruby-on-whales setup. To get overmind running I add some changes to my Dockerfile

1. Add go

COPY --from=golang:1.19.1-bullseye /usr/local/go/ /usr/local/go/

ENV GOPATH=$HOME/go
ENV PATH $PATH:/usr/local/go/bin:$GOPATH/bin

2. Install tmux using apt-get
3. Install overmind:

RUN go install github.com/DarthSim/overmind/v2@latest

This is working, but when I try to start all Processes I get Permission denied 😔

What am I doing wrong?

Thanks
