Quick Docker Test

I’m building a quick image to test permissions to a folder structure for a friend … so I’m making a quick note about how I’m building this test image so I don’t have to keep re-typing it all.

FROM python:3.7-slim

RUN apt-get update && apt-get install -y curl --no-install-recommends

RUN mkdir -p /srv/ljr/test

# Create service account
RUN useradd --comment "my service account" -u 30001 -g 30001 --shell /sbin/nologin --no-create-home webuser
# Copy a bunch of stuff various places under /srv
# Set ownership on /srv folder tree
RUN chown -R 30001:30001 /srv

USER 30001:30001
ENTRYPOINT ["/bin/bash", "/entrypoint.sh"]

build the image

docker build -t “ljr:latest” .

Run a transient container that is deleted on exit

docker run –rm -it –entrypoint “/bin/bash” ljr
