Odin automatically detects if you are running with BepInEx and adds the environment variables appropriately.
DISCLAIMER! Modding your server can cause a lot of errors. Please do NOT post an issue on the valheim-docker repo based on mod issues. By installing mods, you agree that you will do a root cause analysis to why your server is failing before you make a post. Modding is currently unsupported by the Valheim developers and limited support by the valheim-docker repo. If you have issues please contact the MOD developer FIRST based on the output logs.
Mod development is slow, and the more mods you have the more complicated it will be to keep everything up to date. It is a suggestion that you turn off the AUTO_UPDATE variable when you are using mods and refrain from updating your local client until all your mods have been updated. Some mods break on new updates of Valheim while others do not. Be on the look out for mod issues if you update your server.
