Best approach for hosting more than one kopano company on one host

asr-systify

Hello everyone,

I could not find any other related forum threads - altough I have to admit that I cannot think of any good search words.

I have the request/scenario to host groupware (mail, meet, owncloud) for several workgroups. Ideally, it should run under one domain with different subdomains and be completely separated in terms of content: 1 docker host, 1 domain and different subdomains for the respective groups.

Thanks to the well-documented docker environment, i was able to quickly host a kopano test. However, i now have to ask myself what would be the best approach or what is possible at all:

Deploy multiple docker stacks with their own mailserver, ldap and kopano = can this work properly in regards of DNS since only one domain is used? Using traefik as reverse proxy I should get the accesses routed correctly, but a correct certification of the mails worries me.
Using just one ldap and one mailserver for the host and deploy several docker stacks with kopano = from the ldap point of view i think i can handle it well but the mailserver for example has to assign the kopano mailstore (POSTFIX_DAGENT=lmtp:kopano_dagent:2003). Since I have several kopanos behind one mailserver, how can this structure be realized for different kopanos?
Set up only one kopano docker environment and work with permissions in ldap/kopano? Here I lack the experience how far kopano can delimit content and users.

Could someone already gain experience for these requirements and steer me in the right direction?

Best regards
Andre

Hi @asr-systify,

in the end this pretty much depends on personal choice, I would say.

From a perspective of optimal utilisation I would deploy I central ldap, database server and mta. Then you have a “single” point where you can tune/backup/maintain these components. Routing to different kopano-dagents is nothing that works out of the box with the container that is part of the example setup, but is something trivial to achieve with transport maps in Postfix.

Kopano has native multi tenancy functionality for this. How to test multi-tenancy is explained at https://github.com/Kopano-dev/kopano-docker/tree/master/ldap_demo in the docker example.

Hi Felix,

thank you for your response and pointing me to the correct directions. I will have a closer look at both topics.

Best regards,

You can configure multi tenant mode of the Kopano server by following these steps.

KCCONF_SERVER_ENABLE_HOSTED_KOPANO=YES
KCCONF_LDAP_LDAP_COMPANY_TYPE_ATTRIBUTE_VALUE=kopano-company

Also, I am using Cloudways managed hosting and I have done this process through their platform which is much easier.
