Let's Encrypt SSL
I used Let's Encrypt (LE) to get a nice SSL cert for www.riseos.com (and riseos.com, though I really would like that to simply redirect to www. Someday I'll wrap up all the loose ends).
Going through the process wasn't too bad, but unfortunately it was a bit tedious with the current flow. To pass the automated LE checks, you're supposed to place a random string at a random URL (thus demonstrating that you have control over the domain and are therefore the likely owner). I thought I would do this by responding to the url in my existing OCaml app, but
- The deploy feedback cycle is just too long
- The SSL cert generated by
make secretsdoesn't pass work for the check.
In the end I simply switched the DNS records to point to my local machine, opened up my router, and copy/pasted the example python code. Because I use Route53, it was instantaneous. Then after a bit of mucking about with permissions, I copied
secrets/server.key, fixed the dns records, redeployed (now a single script on a local vm + a single script on an EC2 vm), et voila, a working SSL site!
There are some problems with the Let's Encrypt certificate however. The JVM SSL libraries will throw and error when trying to connect to it, saying something like, "unable to find valid certification path to requested target". That transitively affects Apache HttpClient, and therefore clj-http. In the end, I had to pull the cert and insert it into the keystore.
As a side note, the deploy cycle is still too long, and still too involved, but it hugely better than just a week or two ago. I expect to soon be able to remove the EC2 vm entirely, and to be able to run a full, unattended deploy from my VM - or even better, from CircleCI after every push to master. After those sets of paper cuts are healed, I want to do a full deploy on a fresh account, and get the time from initial example-mirage git checkout to running publicly-accesible server (possibly with valid https cert) to under three minutes, on either EC2, Prgmr, or Google Cloud (or Linode/Digital Ocean if anyone knows how to get xen images booting there).
