Troubleshooting Docker
One of the most common causes of failure of the YOUnite stack is lack of memory or disk space. Ensure that the Docker configuration is correct and that the hard drive with docker on it is not out of memory.
It’s not always apparent that this is the case, but things like containers stopping or restarting unexpectedly is one sign. Sometimes a docker container may also give a hint that it cannot allocate memory or disk space.
Checking Available Memory
To see how much memory Docker has available, run the following command and look for the line Total Memory
:
docker system info
Freeing up Docker Disk Space
Docker may run out of disk space over time via normal usage. To free up space run the following commands, which will remove orphaned containers and volumes:
docker system prune docker volume prune
