Mate tuseni v cem je problem?

[pokornyIt]

Pěkný den, konkrétní chyba v message znamená [Errno -3] Temporary failure in name resolution. Zdá se, že je nějaký problém s nastavením DNS, když aplikace běží v HA.

Asi bych se podíval na následující věci:

• Python venv použitý v image
• Nastavení DNS resolveru pro docker compose (https://docs.docker.com/engine/network/)

Bohužel jsem nikdy nespouštěl HA pouze v Dockeru, takže moc nepomůžu.

[marys007]

• Dobral jsem se stejneho nazoru.
• S dockerem problem nebude, protoze pokud zevnitr docker image ze shellu spustim curl GET request na www.cesdistribuce.cz/... odpoved dostanu
• Zda se venv uvnitr dockeru pouzity neni

Problem bude pravdepodobne s DNS prekladem v pythonu. Protoze kdyz si spustim python konzoli a do ni zadam:

/config # python
Python 3.13.1 (main, Dec 15 2024, 21:16:25) [GCC 14.2.0] on linux

S tím bohužel neumím pomoci. Ja to vždy provozuji jako HAOS a daný jsem nikdy neviděl.
