Tips and Trics

Filter out just container name

docker ps | awk '{print $NF}' | grep -w somename

How to run more complex commands | docker exec

docker exec -i container_name bash -c "cd /root/python && python myscript.py"

List containers by name

docker ps --format '{{.Names}}'

Find the log path of container

docker container inspect YOURCONTAINERNAME --format "{{ .LogPath }}
