HA logs - repeated monitor_docker error

[mwunderling]

Am running HA Core in Docker. I also have watchtower setup to monitor a few other containers but not for HA....to limit breaking changes.

Since installing monitor_docker a few days ago, my HA logs have been filling up with the error msg below. 2 unique lines repeated over and over.

Conflict with Watchtower??

Shouldn't be a conflict, but can you confirm if your watchtower is running "network: host" mode or not? I can't see the root-cause, but I make a quick fix to prevent filling up your logging (the network monitoring won't come back). Just grep all the *.py in the "monitor_docker" of the main branch and let me know if that at least solves your filling of the logfile.

Ok, biggest hurdle is I wasn't sure why watchtower was appearing in my HA log since I don't have it active on my Home Assistant container. ....but yes, after looking at the docker compose for watchtower network mode was actually "none". Updated and after restart the error appears resolved. Thanks!

Thanks for reporting back, and I will test with "network=none" and update the code to ignore this one.

I have tested it, and made a 'fix' for it too. Now "network_mode=none" will be automatically ignored during network monitoring.
