RE: Issue running Dovecot in Docker Container

30 Dec 2019


      Maybe start over with your configuration. Start with default setup, see
if everything is running and then start changing the configuration step
by step, see when it goes wrong. I saw you have some ldap configs, maybe
outside communication fails, acls? sff level?
I saw you were using this el7. I am also fan of using 'professional
supported' distributions like el7/centos7. But have a look at this
alpine linux. My dovecot-proxy container is only 30MB vs 300MB on el7.

I'm not using internal logging. I'm running the docker with the logging
to the host.
I have used the same options you have specified.
The problem is that the below processes are not running inside docker
container whereas the standalone dovecot is running these
processes(meaning without container)
dovecot-Dovecot/auth
dovecot-Dovecot/ssl-params
dovecot-Director/lmtp
dovecot-Director/ssl-params
dovecot-Director/imap-login director
Thanks & Regards,

I encountered. Dovecot is dropping to the 'dovecot' and
'dovenull'(?)
when needed, this is fine.
PS. I would not recommend using internal logging, use something 
like
this to log to the host or remote syslog.
docker run -v /dev/log:/dev/log -it dovecot-proxy

Hi Marc, 

I can see the processes are running as a root in container 
environment.
Do you think that still have issues ?
Here is the processes running inside container:
bash-4.2# ps -ef
