A script for configuring Let's Encrypt SSL certificates for CloudFoundry apps on IBM Bluemix
Using the --path argument of the cf map-route command, you can configure a specific path to be directed to a separate app. The benefit, in this situation, is that you can automate the configuration of SSL certificates for your custom domain applications by running the letsencrypt certbot code in a separate instance without disrupting your application.
NAME:
map-route - Add a url route to an app
USAGE:
cf map-route APP_NAME DOMAIN [--hostname HOSTNAME] [--path PATH]
EXAMPLES:
cf map-route my-app example.com # example.com
cf map-route my-app example.com --hostname myhost # myhost.example.com
cf map-route my-app example.com --hostname myhost --path foo # myhost.example.com/foo
OPTIONS:
--hostname, -n Hostname for the route (required for shared domains)
--path Path for the route
Firstly you must have the Bluemix CLI installed, custom domains created, DNS configured, and set your target of choice.
Once ready:
- download/clone this repo
- rename domains.yml.example to domains.yml
- enter your email address (e.g. for certificate renewal reminders)
- enter your custom domain name and its corresponding hostnames
Each [host].[domain] combination will become a separate DNS name in the SAN field of the requested certificate. Set the first host value to '.' to set the Subject Common Name to the name of the domain.
Note: During testing, please set staging to true in order to keep load off the production Let's Encrypt environment and reduce the chance of hitting their rate limits (https://letsencrypt.org/docs/staging-environment/).
Finally, run python setup-app.py to
- push the cf-letsencrypt application
- map the routes needed for Let's Encrypt to verify that you own the domain
- initiate and complete the Let's Encrypt ACME protocol for obtaining a certificate
- download the resulting certificate, and
- upload it into Bluemix for your custom domain
