Docker container could not be stopped

I'm running idoop/zentao:latest (zentao version: 11.6.1) docker container that includes Mysql server, apache server and web application.

When I try to connect to it using docker exec -it df4f599c64ec bash command - it hangs.

When I try to stop it using docker stop df4f599c64ec command - it hangs showing no errors.

When I try to commit it using docker commit df4f599c64ec zentao-25102019 command - it hangs.

When I connect to mysql inside of it - it connects to mysql's shell.

When I open hostaddress:81 which is my container's web application, it says, that

Can't create tmp directory, make sure the directory /opt/zbox/app/zentao/tmp/ exists and has permission to operate.

but before stop command it was working.

[root@ol7 ~]# docker ps -a
CONTAINER ID        IMAGE                 COMMAND               CREATED             STATUS                   PORTS                                        NAMES
df4f599c64ec        idoop/zentao:latest   "docker-entrypoint"   13 days ago         Up 13 days (unhealthy)   0.0.0.0:81->80/tcp, 0.0.0.0:3307->3306/tcp   zentao

I don't know, why this happened. Maybe because of lack of memory, because of 1.2Gb/6Gb of swap is used and only 143Mb/7.4Gb of RAM is free. Docker is running inside of proxmox VM. Host for docker is Oracle Linux 7.

How could I stop this container without loosing its changes? Will docker service restart help?

Updated: Checked my disk space:

[root@ol7 spacer]# df -h

tmpfs                  724M     0  724M   0% /run/user/0

It seems that I have no space required for docker to proceed.

1How could I stop this container without loosing its changes? A container is a throw-away thing. If you need to persist data in the container, you set up "volumes", so that the data exists independently of the container. If you need to make configuration changes, you create a derived image with a Dockerfile and docker build. Note that the doc says you should start a container with a volume (-v /data/zbox/:/opt/zbox/), which by the way defines an /opt/zbox. – xenoid – 2019-10-25T06:47:25.397
