I would like to use awk in gitlab-ci.yml to kill a docker container. However, awk does not work as expected. For example, I want to kill a docker container called ADockerContainer using awk. Therefore I use the following command:

docker kill $(docker ps | grep ADockerContainer | awk '{print $1}')

After the execution of the command, I get:

"docker kill" requires at least 1 argument.

Does anyone know how to fix this?

CodePudding user response：

docker kill (and other commands) will take the container name directly, so you don't need any sort of command substitution here. It's enough to run

docker kill AContainerName
