Troubleshooting

Like any complex system, the EDD will sometimes fail to behave as expected. The steps listed in this document can help narrow down where a fault is occurring, and assist in fixing any problems.

Check container status

Run docker ps -a to get a listing of every container and its current state. If the STATUS column in this output has (unhealthy) listed after the uptime, that container should be investigated to find why healthchecks are failing. More information can be found by running docker inspect {CONTAINER-ID} and/or docker logs {CONTAINER-ID}.

Force removing containers

Some containers may not properly exit and clean up after themselves. These containers will show with an Exited status. These can be removed with docker rm {CONTAINER-ID}. To remove all containers, run:

docker ps -aq | xargs docker rm

Force removing volumes

Docker Volumes containing stale data can sometimes cause problems launching containers. You can see a listing of all Volumes with docker volume ls. The list can be limited to Volumes not currently attached to a container with docker volume ls -f 'dangling=true'. Anonymous Volumes will have a 64-character hexdecimal hash as a name; EDD will generate several Volumes with names like {PROJECT}_{SERVICE}data, eddmedia_{TIMESTAMP}, or eddstatic_{TIMESTAMP}.

Volumes can be removed with docker volume rm {VOLUME-NAME}. This will delete ALL data saved to the Volume and remove it! Use the script ${BASE}/bin/backup_volume.sh if you want to recover any of this data. If the Redis service in the edd project is having problems, you could try stopping EDD, then running docker volume rm edd_redisdata before restarting EDD. To remove all volumes, run

docker volume ls -q | xargs docker volume rm

Pull or Build updated images

See the currently installed Docker Images with docker image ls. Run docker-compose pull to check Docker Hub for updated versions of images. Clean up older/unused images with docker image rm {IMAGE-ID} and remove all unused images with:

docker images -qf 'dangling=true' | xargs docker rmi

View logs

Check the log output for containers with docker logs {CONTAINER-ID}, docker-compose logs {SERVICE-NAME}, or docker service logs {SERVICE-NAME}.
