Check is container/service running with docker-compose

• docker-compose ps -q <service_name> will display the container ID no matter it’s running or not, as long as it was created.
• docker ps shows only those that are actually running.

Let’s combine these two commands:

if [ -z `docker ps -q --no-trunc | grep $(docker-compose ps -q <service_name>)` ]; then
  echo "No, it's not running."
else
  echo "Yes, it's running."
fi

docker ps shows short version of IDs by default, so we need to specify --no-trunc flag.

UPDATE: It threw “grep usage” warning if the service was not running. Thanks to @Dzhuneyt, here’s the updated answer.

if [ -z `docker-compose ps -q <service_name>` ] || [ -z `docker ps -q --no-trunc | grep $(docker-compose ps -q <service_name>)` ]; then
  echo "No, it's not running."
else
  echo "Yes, it's running."
fi
