In the past few days, I’ve seen a number of people having trouble getting Lemmy set up on their own servers. That motivated me to create Lemmy-Easy-Deploy, a dead-simple solution to deploying Lemmy using Docker Compose under the hood.
To accommodate people new to Docker or self hosting, I’ve made it as simple as I possibly could. Edit the config file to specify your domain, then run the script. That’s it! No manual configuration is needed. Your self hosted Lemmy instance will be up and running in about a minute or less. Everything is taken care of for you. Random passwords are created for Lemmy’s microservices, and HTTPS is handled automatically by Caddy.
Updates are automatic too! Run the script again to detect and deploy updates to Lemmy automatically.
If you are an advanced user, plenty of config options are available. You can set this to compile Lemmy from source if you want, which is useful for trying out Release Candidate versions. You can also specify a Cloudflare API token, and if you do, HTTPS certificates will use the DNS challenge instead. This is helpful for Cloudflare proxy users, who can have issues with HTTPS certificates sometimes.
Try it out and let me know what you think!
And that is why I don’t advertise this as supporting email out of the box, and why it’s an advanced option without any support from me. The embedded postfix server is part of the official Docker Compose deployment from upstream Lemmy, and it’s part of the officially supported Ansible deployment too. Those deployment methods are what this is modeled after. That is as far as I go on email support. If upstream Lemmy started including some automatic AWS SNS configuration, I would adopt it, but they have not done so.
Everyone who has reported success to me so far are running single user instances for themselves. That is my target audience, and for that audience (and myself), email is not even close to being a hard requirement.
However, if you would like to improve this script by adding support for more robust and secure email systems, I would be happy if you submitted a PR to do just that :)
