Edit on Git
  1. Unix

Checking files in Docker build context

Sometimes we need to check files in Docker build context, or just to check .dockerignore is work or not

Build this Dockerfile

FROM busybox

RUN mkdir /tmp/build/
COPY . /tmp/build/
RUN du -ah tmp/build | sort -n -r | head -n 100
docker build .
PreviousGit - Pretty git branch graphsNextBash get the directory of the current script
