migrate production release to container

[rahulbot]

We need to move the production install to a new server and a larger shared hard drive. Here's the plan I have in mind:

Photos on hard drive:

• rsync large photo dir to shared drive
• point current prod version at shared drive for photos (via symlink)
• verify new photos are still coming in

Database:

• migrate production database to container
• point current prod version at containerized DB
• deactivate and archive current prod database

App:

• prep code for containerized deployment (Dockerize application #209)
• test containerized version on new prod server
• switch DNS to new containerized version

I started the rsync of the photos directory to the shared drive connected to the current prod server: rsync -av app/assets/images/kiosko/ /mas/u/pageonex/app/assets/images/kiosko/

Ran the rsync. The goal of the first task here is to get these images onto hard drive that has enough space to handle it (around 130GB of images). Next step is to point the current prod install at this bigger drive. @numeroteca can we find a time to do that together so that there isn't a gap like last time I tried?

In #218 there's a lot of information on how to set a prod environment for pageonex and a way to test images locally.

Update - image directory switched over to external drive. Will delete current image dirs in a week if it seems to be working well.

Next up is moving the database to the new server. I'll try to do that next week (looks like I need to edit the production section of config/database.yml).

[rahulbot]

Database switched over, now we just need to get the code working in the container and we'll be good to go.

Note: Solved some other problems on #220

[rahulbot]

Container pointed at production DB/images is now online at http://pageonex-prod.brownbag.me. @numeroteca can you please poke at it to make sure it seems good. If that checks out then we can switch over the DNS to point at this new server.

[numeroteca]

Everything looks good in the tests I've made. Prepared to point the DNS to the new server. I wait for instructions.

[rahulbot]

Nice - can you please change the DNS to point both dev.pageonex.com and pageonex.com to 18.85.22.29? I have the containers set up to respond to those so hopefully it'll just work ;-)

[numeroteca]

Changed pageonex.com to 18.85.22.29.

dev.pageonex.com was already pointing to 18.85.22.29, so no change needed.

Let's see how it goes.
