# Dockerfile for pgtop
# ====================
#
# Build the docker container as:
#
#    docker build -t my_pgtop .
#
# You most probably will want to run pgtop pointing it to your database
# rather than localhost:5432, so make sure to build a pgtoprc file
# from the provided sample `pgtoprc.sample`. After you've done that,
# run the docker container with:
#
#    cp pgtoprc.sample pgtoprc
#
#    # Edit the pgtoprc file to add your database host, port, name, etc..
#    docker run --rm -it -v ./pgtoprc:/app/.pgtop my_pgtop
#
