migrate www.buttonweavers.com to ECS

cgolubi1 commented 4 months ago

Deploy the changes made for #2908 and tested on staging on #2937 to the production site.

Plan (copied from steps i ran for staging on #2937):

Pre-migration steps:
- [x] I can create the NLB target groups (but not the NLB itself) before the cutover
- [x] Once the target groups are created, all data needed for buttonmen_ecs_config.json is knowable. So the next step is to fully fill out all entries for the stage in that file.
- [x] Create the PR to bring the new deployment code over to the production branch, and merge it.
- [x] Create an updated-and-ready-to-go production checkout with this code, and have the deployment command i'll use ready to hand
At this point, i have to take the staging site offline to go further, because i need to move its EIP to the NLB at NLB creation time. So i think the steps are:
- [x] Stop (do NOT terminate, we need it if we have to roll back) the production instance
- [x] Create the production NLB
- [x] Run the deployment

Ideally, that's it. If anything goes wrong, roll back and revisit.

This should be basically ready to go. I'll setup the PR and checkout tomorrow morning, in case anything changes between now and then for some reason.

cgolubi1 commented 4 months ago

Starting the prep work now.

cgolubi1 commented 4 months ago

My workspace is ready to go. Waiting until 16:00 UTC, since that's when i said i would kick this off.

cgolubi1 commented 4 months ago

Okay, off we go, taking the prod instance down now.

cgolubi1 commented 4 months ago

Disassociated EIP from prod instance.

cgolubi1 commented 4 months ago

Created NLB, waiting for it to finish provisioning.

cgolubi1 commented 4 months ago

Okay, done. Kicking off the deployment now.

cgolubi1 commented 4 months ago

That's running --- the next step takes about 15 minutes (it will always take that long, but usually the site is still available running the old container while it happens --- the downtime is only because of the cutover from EC2 to ECS).

cgolubi1 commented 4 months ago

Okay, the site appears to be running. Let's check things out.

cgolubi1 commented 4 months ago

I can take normal actions on the site, and when i do, log entries show up on the container. We received the e-mail with the container's IP address. There's not really much else to check; either it works or it doesn't, and it seems to work.

cgolubi1 commented 4 months ago

Closing this out. Let's hold off on merges for about a day just in case anything urgent comes up, and then go from there.
