Piping a file into docker run
I need to pipe (inject) a file or some data into docker as part of the run command and have it written to a file within the container as part of the startup. Is there best practise way to do this ?
I've tried this.
cat data.txt | docker run -a stdin -a stdout -i -t ubuntu /bin/bash -c 'cat >/data.txt'
But can't seem to get it to work.
cat setup.json | docker run -i ubuntu /bin/bash -c 'cat'
This worked for me. Remove the -t. Don't need the -a's either.
