Thanks! I guess default-libmysqlclient-dev drags in zlib1g-dev for some reason that the Oracle package doesn’t. Everything builds with the Oracle libmysqlclient now, so I’m good to go.

I’m not actually going to do much with this build until Debian 9 is released and all the packages that I use have had time to be production hardened on Debian 9. I’m building against Ubuntu 16.04 for my actual work. I really want to use Debian 9 in production since it comes with OpenSSL 1.1.0e and I want to support the ChaCha20-Poly1305 ciphers for NGINX sessions (and maybe Dovecot too). https://github.com/openssl/openssl/issues/304 <https://github.com/openssl/openssl/issues/304> Any other comments on my Dockerfile? Since everything builds, I assume it uses sane options to build Dovecot. I couldn’t find any other example Dockerfiles for building Dovecot so just made this one up from other Dockerfiles that I use to build other images. I’d really like to see an official Dovecot image in the Docker Hub and base my containers off that. I actually use s6-overlay and other extras in my real Dovecot image, but it would be nice to see a Dockerfile that is based on Alpine Linux too. Alpine seems to be the preferred distro for official Docker Hub images, as I understand it. Kevin
