Stop a Docker container that's been running for a certain amount of time

Question

I'd like to create a cron job that would stop Docker containers if they've been running for more than, say, 2 hours.

I can get the times they started.

$ docker inspect -f '{{ .State.StartedAt }}' $(docker ps -q)

Just need to compare that with 2 hours ago...

$ date --utc --date="-2 hours" +"%Y-%m-%dT%H:%M:%S.%NZ"

...and if it's earlier stop the container

$ docker stop <<container_id>>

How can I do this with a bash script?

Answer 1

It is an old thread but still if someone is searching for an answer. The below command will stop containers running more than 2 hours.

docker ps --format="{{.RunningFor}} {{.Names}}"  | grep hours |  awk -F: '{if($1>2)print$1}' | awk ' {print $4} ' | xargs docker stop

Explaination:

docker ps --format="{{.RunningFor}} {{.Names}}" 

will print the container names and running period.

grep hours 

will print the containres running in hours.

 awk -F: '{if($1>2)print$1}' 

will only print containers running for more than 2 hours.

awk ' {print $4} ' | xargs docker stop

will print the container names obtained from previous output and pass it as argument to stop the containers.
