Update does not work in Docker

For an automatic update or update in the admin panel to work with .NET 8 in Docker, several things must work. The most important thing is that Watchtower works.

For this, you can view the Watchtower log file.

docker logs teslalogger-watchtower

Best is to press Update in the admin panel and watch the log:

If you find such an error message in the log file, you need to update the docker-compose.yml.

client version 1.25 is too old. Minimum supported API version is 1.44, please upgrade your client to a newer version"

Manual update:

docker compose stop
wget https://raw.githubusercontent.com/bassmaster187/TeslaLogger/refs/heads/NET8/docker-compose.yml -O docker-compose.yml
docker compose pull
docker compose up -d

If nothing happens in the Watchtower log when pressing Update in the admin panel, it may be that you have a version of Watchtower that no longer accepts HTTP GET. In that case, also start a manual update.
