Running docker with a HEREDOC to script the commands to run inside the container.
docker run -v /Users/mbreese/tmp:/tmp1 -w /tmp1 -i centos:7 /bin/bash -s <<EOF
date > foo
echo 'foo' >> foo
cat /etc/redhat-release >> foo
whoami >> foo
EOF

Great work
Not too sure how to use this with an if, should it look like this?

if docker-compose exec container bash -s << 'EOF'; then
# script to run
EOF
some commands
fi

Alternative without the use of "bash -s"

$ cat <<"EOF" | docker run --rm -i --name ${DOCKER_CONTAINER_NAME} ${IMAGE_NAME}
  date > foo
  echo 'foo' >> foo
  cat /etc/redhat-release >> foo
  whoami >> foo
EOF

with docker-compose and heredoc syntax

cat <<"EOF" | docker-compose exec -T app /bin/bash -
  cat /etc/os-release
EOF
