Is it possible to honour the docker autostart delay?

[lonzodelorana]

Updating docker containers will stop/update/start the container immediately and then proceed to stop/update/start the next, however on older or low power hardware this can end up with the containers updating but failing to start.

The Unraid docker implementation has an autostart delay built in, used to slow down starting of containers after a reboot for just this issue, is it possible to honour this delay before starting the next update procedure, so containers can update without manual intervention on this sort of setup please?

on older or low power hardware this can end up with the containers updating but failing to start.

How? These actions happens in order. I dont know why this should fail - and with what error message? The container delay is being respected at container start - but AFTER it started.

If there are race conditions, it must be an issue with docker itself. Please provide a error message (syslog?)

I could add a static 3 second wait after internal docker update. Should hurt nobody.

Actually, it looks like I made a huge assumption over why the containers were not starting and it looks like the docker autostart delays are indeed honoured by appdata.backup. My sincere apologies.

I believe what is happening is a container which is being used as the networking for other containers is being updated and it looks like as the dependant containers are recreated due to the networking change, appdata.backup can't find the containers to start them, log snippet below.

When checking back in the unraid GUI in the morning, all containers are present, just not started

Again, sorry for the assumptions!

[Commifreak]

Thats weird. But the names do not change, doesnt it?

[lonzodelorana]

nope, the names are the same, rebuild only takes 30 -60 seconds or so for all of the dependant containers.

The container ID does change though for all of the dependant containers

[Commifreak]

The container ID is not being used for those actions. Please submit a debug log and share its ID. There are some internal debugs in that case.

[lonzodelorana]

Hi,

Sorry for the delay, the most recent debug log didn't have the issue, but it reoccurred last night, so I've submitted the log and the ID is

24d6ffd8-670d-4af5-a111-ae1b129dccfb

I need to adjust my debug things inside the plugin to get a deeper look. Stay tuned.
