As 2020 seems like a good year to get stuff done that has otherwise been neglected, I finally migrated my setup off a very old DigitalOcean droplet. It had been a steady host for years, but my initial plans to migrate from Ubuntu to CentOS7 a while back were never really completed. Centos8 is the new goodness, and I must say it was mostly a real pleasure to set up via DigitalOcean.
In my work at Varnish Software I liked to “dogfood” our products and technology, to learn and constantly flex some configuration muscles. So the old stack on denis.no was influenced by this and consisted of:
--------- | Hitch | (TLS termination) --------- | ----------- | Varnish | (Caching and routing) ----------- | --------- | Nginx | (File serving) ---------
As the need for dogfooding isn’t there anymore, and convenience outweighs most other factors these days, I’ve now reduced that stack to:
---------- | Caddy2 | (TLS termination, file serving and routing) ----------
I still have a couple of smaller services left which are set up with
reverse_proxy in Caddy.
Installing Caddy2 was almost too easy, and it involved ditching hundreds of lines of configuration for a very neat and consise
The documentation for Caddy2 was pretty good, and made the process of migrating relatively quick and painless. I always wanted the super-neat LetsEncrypt cert integration, and that worked out just as well as I expected.
