acidDrain / pipe-to-container.md
Created August 26, 2021 01:41
Example of how to pipe output into a container 
# This is how piping a file into a container could be done for a build.
# The container’s ID will be printed after the build is done and the build logs
# could be retrieved using docker logs. This is useful if you need to pipe a
# file or something else into a container and retrieve the container’s ID once
# the container has finished running.
#
# See https://docs.docker.com/engine/reference/commandline/run/#attach-to-stdinstdoutstderr--a
