unzip: cannot find zipfile directory in one of ../dovecot-2.4.0-example-config.tar.gz or ../dovecot-2.4.0-example-config.tar.gz.zip, and cannot find ../dovecot-2.4.0-example-config.tar.gz.ZIP, period. [slitt@mydesk junk]$
its not a zip file :)
$ tar -xvzf <archive>
There is also a dovecot.conf in the docker image, which you can either read out or swap out for testing.
for example, to read out:
docker run -p 1143:143 -p 1993:993 dovecot/dovecot:latest
CONT_NAME=$(docker container ls --filter="ancestor=dovecot/dovecot:latest" --format='{{.Names}}')
docker cp ${CONT_NAME}:/etc/dovecot/dovecot.conf /tmp/d.confor to swap out:
(assuming you have 'dovecot.conf' and other support files in a local directory)
docker run -p 1143:143 -p 1993:993 \
-v ./:/etc/dovecot \
dovecot/dovecot:latestI found the latter very helpful for syntax checking.
By the way the dovecot binaries are at '/dovecot/bin' in the Docker image, so you can use those with a running Docker instance if needed. eg
docker exec ${CONT_NAME} /dovecot/bin/doveadm config imapCheers
