can't stat '.bashrc' in Alpine linux Dockerfile

Question

I'm having a little trouble trying to spool up an Alpine linux container.

My Dockerfile is very simple but I keep getting an error which i havent seen before.

My Dockerfile is as follows;

FROM openjdk:8-jre-alpine

RUN apk update && apk upgrade && apk --update add \
    ruby build-base libstdc++ tzdata bash ttf-dejavu freetype fontconfig wget curl

RUN addgroup -S newuser && adduser -S newuser -G newuser && \
    cd && cp -R .bashrc .profile /home/newuser && \
    mkdir -p /project && \
    chown -R newuser:newuser /home/newuser /project

USER newuser
ENV HOME /home/newuser

The errors i keep seeing are as follows;

cp: can't stat '.bashrc': No such file or directory
cp: can't stat '.profile': No such file or directory

I dont understand whats going on.

Could anyone shed some light on this? I have never used Alpine Linux before.

Answer 1

Alpine Linux only has the sh shell not the bash shell so I don't think that file would exist. I'm pretty sure you can install the bash shell and create your own.bashrc.

Answer 2

Are you sure that the root's home directory actually contains.bashrc and.profile? More likely than not, these are not present. The default shell is ash. Have a look at the image contents.
