How do I use custom domains?
$ cf create-domain cf-hero-YOUR-NAME YOUR-NAME.cf-hero.cloudcredo.io
# From the training home directory:
$ cd 08-domains-routes/cf-hero
# Uncomment domain & replace YOUR-NAME
$ vim manifest.yml
$ cf push


Note: We can add our custom domain to our CF org.

I want multiple routes
pointing to the same app
$ cf map-route cf-hero gerhard.cf-hero.cloudcredo.io -n www
$ cf apps

name     ..  urls
cf-hero  ..  gerhard.cf-hero.cloudcredo.io, www.gerhard.cloudcredo..


I also want multiple domains
pointing to the same app
$ cf domains

name                            status
cfapps.io                       shared
gerhard.cf-hero.cloudcredo.io   owned
$ cf map-route cf-hero cfapps.io -n gerhard-cf-hero
$ cf routes

space         host              domain                          apps
development                     gerhard.cf-hero.cloudcredo.io   ...
development   www               gerhard.cf-hero.cloudcredo.io   ...
development   gerhard-cf-hero   cfapps.io                       ...


Note: Every Cloud Foundry installation will have at least one shared domain

This is shared across all apps deployed on that Cloud Foundry

Even though we are using no host with our custom domain, we cannot use no host with the shared domain

Shared domains have reserved hosts, such as api

What about multiple
domains & routes?
$ cat imaginary-manifest.yml

name: cf-hero
domains:
  - cloudcredo.io
  - cloudcredo.com
hosts:
  - gerhard
  - gerhard-lazu
$ cf routes

space          host            domain            apps
development    gerhard         cloudcredo.io     cf-hero
development    gerhard-lazu    cloudcredo.io     cf-hero
development    gerhard         cloudcredo.com    cf-hero
development    gerhard-lazu    cloudcredo.com    cf-hero
Experiment with app versions
$ cf push -f manifest-superhero.yml
And when it did its job...

$ cf delete -f -r cf-superhero


When you find
the best app version
# From the training home directory:
$ cd 08-domains-routes/cf-hero-static
# Replace YOUR-NAME
$ vim public/index.html
# Uncomment domain & replace YOUR-NAME
$ vim manifest.yml
$ cf push
$ cf app cf-hero-static
