Error message when starting ddev laravel: "Failed waiting for web/db containers to become ready: web container failed" (zfs)

When I initially cloned a company repository and tried to start via ddev start I got the error message Failed waiting for web/db containers to become ready: web container failed. The container ddev-website-web stays unhealthy. The browser page shows an error.

Solution

Short answer: The error is a known problem with overlayFS on ZFS, see Moby #45890 on github

Long answer: You can check easily, if the error fits to you.

When the ddev-web container is started you can login into the container via ddev ssh then show the user and groups of the folder /etc/apache2/sites-enabled/.

If the user and group is root, there will be an apache-Folder inside and in this folder the correct files will be inside. If you try to remove the folder with sudo rm -rf /etc/apache2/sites-enabled you will get an error invalid argument.

This pointed my college to this issue: issue 46640 on github

So please check, if you're using overlay mount with zfs with docker info

Storage Driver: overlay2
  Backing Filesystem: zfs

Then you can use this Solution:

To avoid this error, just do like in docker docu-use zfs described.

Be sure to backup all containers that You can't get via docker pull!
stop docker service docker stop
make sure to have enough free space (temporary)
create backup of docker-files: sudo cp -au /var/lib/docker /var/lib/docker.bk
if necessary, unmount mounted docker folders
- cat /proc/mounts | grep docker
- sudo umount /path (source: Github)
edit /etc/docker/daemon.json and add
- { "storage-driver": "zfs" }
after saving file, start docker again service docker start
after a short time docker info should show Storage Driver: zfs
if everything works, remove the former docker folder sudo rm -rf /var/lib/docker.bk

Your problem should be solved.
