First, make sure that your fstab file is correct for your nfs mounts.
x.x.x.x:/mnt/thunder/audio /mnt/nas/audio nfs rw,intr,nfsvers=3,x-systemd.automount 0 0
x.x.x.x:/mnt/thunder/video /mnt/nas/video nfs rw,intr,nfsvers=3,x-systemd.automount 0 0
x.x.x.x:/mnt/rain/docker /docker nfs rw,intr,nfsvers=3,x-systemd.automount 0 0
Then we need to make sure things start up in the right order. For docker, I added...
vim /etc/systemd/system/multi-user.target.wants/docker.service
[Unit]
... snip ...
BindsTo=containerd.service
After=network-online.target firewalld.service containerd.service
Wants=network-online.target
Requires=docker.socket containerd.service docker.mount mnt-nas-audio.mount mnt-nas-video.mount
... snip ...
To find what your mount names are, you can run the following command.
systemctl list-units | grep /mnt
This should make it where the fstab mounts will mount automatically, and then the docker service (or any service you wish) will only start after the successful nfs mount.
