如何知道哪些 systemd 服务正在运行 docker 容器

Question

Few docker containers on Linux auto restarts when stopped. How can we know which specific systemd services are running these containers? Few steps followed:

"docker ps -a" -- lists all containers with containerID Step 1

"systemctl list-units" -- list all the units Step 2

"systemctl status <Unit -Name>" --Gives location & further details about service

Tried stopping few service units which I believed were responsible for container restarts but it didn't helped. below Commands were followed:

"systemctl stop <Unit -Name >"

"systemctl disable <Unit - Name>"

"rm -rf /etc/systemd/system/ <Unit -Name>" -- removed those specific unit folders as from Step 2 above

But the Units and containers still show up as in Step 1 & 2 above. How to stop and remove these containers?

Answer 1

Are you sure that systemd services restart the containers? Maybe there is a restart policy. Check it with:

docker inspect container_name | grep -A10 RestartPolicy

To remove the container:

docker rm -f container_name
