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.
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.
service docker stop
sudo cp -au /var/lib/docker /var/lib/docker.bk
cat /proc/mounts | grep docker
sudo umount /path
(source: Github)/etc/docker/daemon.json
and add
{ "storage-driver": "zfs" }
service docker start
docker info
should show Storage Driver: zfs
sudo rm -rf /var/lib/docker.bk
Your problem should be solved.
