Multiprocessing Issues in Docker¶

Docker Out of Disk Space¶

What to Do When Docker on the Mac Runs Out of Space

Docker fail to register layer ... no such file or directory¶

Remove /var/lib/docker/*.
```
 :::bash
 sudo rm -rf /var/lib/docker/*
```
If you have a non-standard Docker location configured, then rmeove that location instead.
Restart Docker.
```
 :::bash
 sudo service docker restart
```

Error response from daemon: failed to start shim: exec: “docker-containerd-shim”: executable file not found in $PATH: unknown.¶

Restart docker resolves the issue.

:::bash
sudo service docker restart

Error saving credentials: error storing credentials in Ubuntu 18.04 LTS¶

Installing gnupg2 and pass fixes the issue.

:::bash
wajig install gnupg2 pass

Container exits with non-zero exit code 137¶

Please refer to The Non-Zero Exit Code 137 While Building a Docker Image for more details.

Debuging Docker Container Exit¶

List Docker container IDs.
```
 :::bash
 docker ps -a
```
Check logs of a Docker container.
```
 :::bash
 docker logs container_id
```
Inspect a Docker container.
```
 :::bash
 docker inspect container_id
```

If the above does not help you identify the cause of Docker container exit, you can inspect the logs of the Docker daemon. The StackOverflow question Where is the Docker daemon log? has a good discussion on where/how to find Docker daemon logs. In case you need to figure out which init system your Linux OS is using, please refer to the post Check Whether a Linux Is Using Upstart Systemd or SysV
