Redirection.io Proxy for Clever Cloud

DNS

For HTTP:

CNAME record: domain.par.clever-cloud.com.
A records: 185.42.117.108 185.42.117.109 46.252.181.103 46.252.181.104

CNAME record: domain.par.secondary.services.clever-cloud.com.
A records: 185.42.117.123 46.252.181.120 46.252.181.180

Setup on Clever Cloud

Run all these commands inside the project you are working on. The proxy app will be linked using the .clever.json file.

Application

clever create -a proxy -o "ORG NAME or ID" --type node --region par --github "monsieurbiz/redirectionio-proxy" "Proxy"
clever scale -a proxy --flavor pico
clever config -a proxy update --enable-zero-downtime --enable-cancel-on-push --enable-force-https
clever domain -a proxy add your.domain.com
clever domain -a proxy favourite set your.domain.com

Flavor can be nano if pico is too small, or XS/S to avoid shared CPU or for a more stable instance for high traffic

Be careful! We use our repository to deploy the proxies! Clone it and use your own if needed!

Environment variables

Don't forget to update them!

clever env -a proxy set CC_RUN_COMMAND "./redirection-agent/redirectionio-agent --config-file ./agent.yml"
clever env -a proxy set CC_PRE_BUILD_HOOK "./clevercloud/pre_build_hook.sh"
clever env -a proxy set CC_PRE_RUN_HOOK "./clevercloud/pre_run_hook.sh"
clever env -a proxy set PORT "8080"
clever env -a proxy set RIO_INSTANCE_NAME "CleverCloud"
clever env -a proxy set RIO_PRESERVE_HOST "false"
clever env -a proxy set RIO_ADD_RULE_IDS_HEADER "true"
clever env -a proxy set RIO_COMPRESS "true"
clever env -a proxy set RIO_REQUEST_BODY_SIZE_LIMIT "200MB"
clever env -a proxy set RIO_LOG_LEVEL "info"
clever env -a proxy set RIO_PROJECT_KEY "RIO PROJECT KEY"
clever env -a proxy set RIO_FORWARD "http://…cleverapps.io/"
clever env -a proxy set RIO_TRUSTED_PROXIES ""

RIO_FORWARD is in http! Not https. It is mandatory!

The Pre Build hook downloads the latest redirectionio binary. If you want to force a new version of the agent, force rebuild it.

The Pre Run hook creates the agent.yml configuration file.

Behind a proxy like Cloudflare

You need to declare your proxy's IP addresses.

For Cloudflare: (see https://www.cloudflare.com/fr-fr/ips/)

clever env -a proxy set RIO_TRUSTED_PROXIES "173.245.48.0/20,103.21.244.0/22,103.22.200.0/22,103.31.4.0/22,141.101.64.0/18,108.162.192.0/18,190.93.240.0/20,188.114.96.0/20,197.234.240.0/22,198.41.128.0/17,162.158.0.0/15,104.16.0.0/13,104.24.0.0/14,172.64.0.0/13,131.0.72.0/22"

Start the proxy

clever restart --without-cache -a proxy

Changes to be made on a Symfony app

Framework config:

framework:
    trusted_proxies: '%env(CC_REVERSE_PROXY_IPS)%'
    trusted_headers: [ 'x-forwarded-for', 'x-forwarded-host', 'x-forwarded-proto', 'x-forwarded-port', 'x-forwarded-prefix' ]

.env:

###> clevercloud ###
CC_REVERSE_PROXY_IPS=127.0.0.1
###< clevercloud ###

Troubleshooting

The app keeps redirecting to the CC domain (like `https://app-xxxxxx-xxxx-308021983139.cleverapps.io`)

Don't forget to uncheck the "Force HTTPS" in your app's Information. You can also update it using : clever config update --disable-force-https
