Hi @levasc

Can you provide the docker run command? Just to make sure, the mount information is supplied here: https://github.com/jjethwa/icinga2#sending-notification-mails

I am using docker-compose. I think it tries to mount the files as directories. :) 2020-11-11, tr, 21:14 Jordan Jethwa <[email protected]> rašė:

Thanks @levasc

There is an issue with some versions of docker and docker-compose for volumes that are files. Try putting the exact path to the files on the host system: https://github.com/jjethwa/icinga2/blob/master/docker-compose.yml#L47-L48

For example:

/apps/docker-volumes/icinga2/msmtp/aliases:/etc/aliases:ro

Hopefully that works 😄
