The mailing list for listmasters using Sympa

["Fillmore, Tom" <address@concealed>]

Hi, all - 

My two cents, here...

Docker, when used appropriately, allows you to follow the *nix path of 'do one thing and do it well'.  There are a lot of advantages to containers but it's a mindshift, much like a person suddenly realizing how fantastic piping between programs can be and the changes it makes to how they think.

So - to me this setup makes the most sense:

• A docker container for Postfix (+ spamassassin, amavis, etc)
• A docker container for your database
• A docker container for all things Sympa

With this sort of setup it's easier to both scale up and out.  Assuming there are several containers of each running in unison and a monitoring service for them, if one crashes another could be spun up with very very minimal downtime and no loss of data since it's stored on the host, not in the container.

thoughts?
