- 40. Done with the project for now? > docker stack rm vm
- 41. POPQUIZ! A. How do you check the replication status of services? B. How do you check for error messages on the stack? > docker stack ps vm —no-trunc BONUS POINT How do you avoid truncating the error message?
- 42. Same project … multiple production targets? docker-compose.yml docker-compose-clientA.yml docker-compose-clientB.yml
- 43. POPQUIZ! A. How do you filter a list of docker objects (services, containers, images, etc)
- 44. SIDEBAR:The $( ) magic with -q -l -f -q Quiet (ID only) -l Last Updated Only (1 result) -f Filter (you remember this) > docker container ls -q -l > docker container exec -it $(docker ps -q -l -f name=vm_web) bash
