Quick reference guide for Docker commands - not at all exhaustive, just a cheat sheet.
Monitoring/Removing Images
| task |
command |
| remove all untagged images |
docker rmi $(docker images | grep "^<none>" | awk '{print $3}') |
| remove dangling images |
docker rmi $(docker images -q -f dangling=true) |
Monitoring/Killing Containers
| task |
command |
notes |
| see running containers |
docker ps |
like ps in bash! |
| see most recently launched container |
docker ps -l |
-l for last |
| see all containers |
docker ps -a |
-a for all |
| see hash of running containers |
docker ps -q |
-q for hash |
| see hash of most recent container |
docker ps -ql |
mix -q and -l for hash of last |
| see hash of all containers |
docker ps -aq |
ditto for -a and -q |
| kill all running containers |
docker kill $(docker ps -q) |
kill only stops running containers |
| kill most recent container |
docker kill $(docker ps -ql) |
|
| remove all exited containers |
docker rm $(docker ps -qa) |
rm only removes exited containers |
| remove all containers |
docker rm -f $(docker ps -qa) |
-f forces rm to kill and remove |
