A docker compose command that brings up a service without a command

Here is a fun one I got whilst trying to justify why abusing docker compose accepting file inputs from stdin is a very powerful pattern

# Bring up services without a command
# usage:
# up -d service_name

function _compose {
  docker-compose -f docker-compose.yml $@

function nocmd {
  cat << EOF
      command: tail -f /dev/null

function nocmd_compose {
  local service=${@: -1}
  _compose -f <(nocmd "$service") $@

nocmd_compose $@
