MagicMirrorOS build intermittently not starting mm container (Version 2.30)
-
from the beginning
-
@karsten13 hm…
-
well, I did not promote it because the image base was to old (beside other problems) but in 2024 I decided to do a complete refactor so now the image build (iso, not docker) is done by me with gitlab based on the current raspian bookworm os lite.

@scottwalsh please dont double post

@sdetweil
The host is a pi zero 2w - so is on the low spec side. -

Apologies, user error.

@scottwalsh how big is the swap file?

@karsten13 @scottwalsh
bookworm is about 500m bigger that bullseyeso swap is critical on small memory machines
-
mmos is critical with pi zero 2w, I had a user who gave up, but it depends on installed modules and quality of used sd-card.
CONF_SWAPSIZE=1024(if not changed by user) -
@scottwalsh can you show w MagicMirror running…
-
An observation, if I power cycle the pi, there is a good chance of it not starting up with the errors in the original post.
Once leave it for five min for all the processes to start (and fail), then run docker compose up -d --force-recreate, it seems to be stable from then on and works well.

@scottwalsh probably swap file speed bound

the script
/opt/mm/install/install.shis executed with every reboot.As workaround you could add
sleep 10s docker compose up -d --force-recreateat the end (where you have to play with the sleep seconds).

Is that executed on the OS boot, or by one of the containers as they start?
I was thinking of a workaround like that to introduce a pause. Given the low machine spec, it seems to be busy for about 5min after sshd starts, so will just try a 300 sec sleep.

on OS boot
-
As an update, based on the pointers from @KARSTEN13 and @SDETWEIL, have a workaround.
Had three issues going on.
1:
I found that on a graceful reboot (shutdown -r now) that it would generally start fine, but not on an ungraceful reboot (power cycle the machine).Looks like when it was ungraceful reboot, the labwc container would show with uptime of (for example) five hours when ‘docker ps’, even though the machine was rebooted 20min ago after ‘docker compose up’ was executed by install.sh. Whereas the magicmirror container would have recently started.
I assume kind of lock file confusing things?
Workaround was to change the first ‘docker compose up’ install.sh to ‘docker compose up -d --force-recreate’
2:
I’d also included a pause and --force-recreate at the end of the install.sh and noted it was never executing as per @KARSTEN13’s suggestion.
Looked like the install.sh script was hanging at docker compose pull.
Commented that out.3:
Lastly, the initial ‘docker compose up -d --force-recreate’ in install.sh would still fail often with the mm container restarting with logs as per the original post.With a 7 min pause and then second ‘docker compose up -d --force-recreate’ it seems to start the second time well (3min wasn’t enough, 5min was better, 7min seems to work).
Workaround is a bit on the slow side, at some point will see if can refactor it a bit so that a pull for updates occurs.
Extract of resulting install.sh below.
