Sometimes things break. You can find the most recent errors using a combination of journalctl, along with the classic tools sort and uniq Show Sample Output
1journalctl --no-pager --since today --grep 'fail|error|fatal' --output json | jq '._EXE' | sort | uniq -c | sort --numeric --reverse --key 1 -
When you run a lot of containers the built in docker ps output becomes unreadable. This command formats the output to be easier on the eyes. Requires q (https://github.com/harelba/q) text as data. Show Sample Output
0docker ps | sed -e 's/ /\+/g' -e 's/CONTAINER ID/CONTAINER_ID/' | tr -s '+' '\t' | q -t 'select c1,substr(c7, 0, 40),c2,c6 from -' | column -t -
Applies 'docker rm' to all container IDs that appear in 'docker ps -a' but not in 'docker ps' - i.e. the ones that are not running. Show Sample Output
0$ docker rm `(docker ps -q && docker ps -qa) | sort | uniq -u` -
0docker ps -a | grep 'Exit' | awk '{print $1}' | xargs docker rm
-
0docker images | grep '' | awk '{print $3}' | xargs docker rmi
-
Docker rmi won't remove images from running containers. This just tries to delete everything, so you'll get errors for anything that's in use.
0docker rmi $(docker images -a -q) -
0for containerId in $(docker ps | awk '{print $1}' | grep -v CONTAINER); do docker inspect -f "{{ .Name }}" $containerId | sed 's#/##' ; docker port $containerId; done
-
0docker rm $(docker ps -aqf status=exited)
-
0docker ps -a | grep Exit | awk -F " " '{ print $1 }' | xargs docker rm {}
-
0docker ps -a | grep "Exited" | awk '{print $1}' | xargs docker rm
-
0docker stop $(docker ps -a -q)
-
Run container like a daemon
0docker run -d ubuntu /bin/sh -c "while true; do echo Hello CLFU; sleep 1; done" -
0dockexecl() { docker exec -i -t $(docker ps -l -q) bash ;}
