"Multiple App Ports" Demo Operations for HTTP Routing

1. Cloning demo app
   Using cf-acceptance-tests/assets/multi-port-app
   • git clone https://github.com/cloudfoundry/cf-acceptance-tests.git
2. Creating routes
   • (confirmation before operations) cf routes
   • cf create-route demo-spc bosh-lite.com --hostname mpg2
   • (confirmation after operations) cf routes
3. Pushing app with listening multiple ports
   • cf push mpg -c 'go-online --ports=7777,8888,8080'
   • (checking current status)
     • curl -k https://mpg.bosh-lite.com/ports
     • curl -k https://mpg2.bosh-lite.com/ports -> should fail
4. Updating external ports of app
   • (confirmation before operations) cf curl /v2/apps/$(cf app mpg --guid)
   • cf curl /v2/apps/$(cf app mpg --guid) -X PUT -d '\{"ports": \[7777, 8888, 8080\]\}'
5. Adding route mappings
   • (confirmation before operations) cf curl /v2/route_mappings
   • (checking <ROUTE-GUID>s) cf curl /v2/routes?q=host:mpg2
   • cf curl /v2/route_mappings -X POST -d "\{\"app_guid\": \"$(cf app mpg --guid)\", \"route_guid\": \"<ROUTE-GUID>\", \"app_port\": 7777\}"
   • (confirmation after operations) cf curl /v2/route_mappings
6. Validating behavior
   • curl -k https://mpg.bosh-lite.com/ports
   • curl -k https://mpg2.bosh-lite.com/ports

"Multiple App Ports" Demo Operations for TCP Routing

1. Cloning demo app
   Using cf-acceptance-tests/assets/multi-port-app
   • git clone https://github.com/cloudfoundry/cf-acceptance-tests.git
2. Creating routes
   • (confirmation before operations) cf routes
   • cf create-route demo-spc tcp.bosh-lite.com --port 1077
   • cf create-route demo-spc tcp.bosh-lite.com --port 1080
   • cf create-route demo-spc tcp.bosh-lite.com --port 1088
   • (confirmation after operations) cf routes
3. Pushing app with listening multiple ports, not-started, no-routes
   • cf push mpg-tcp -c 'go-online --ports=7777,8888,8080' --no-route --no-start
4. Updating external ports of app
   • (confirmation before operations) cf curl /v2/apps/$(cf app mpg-tcp --guid)
   • cf curl /v2/apps/$(cf app mpg-tcp --guid) -X PUT -d '\{"ports": \[7777, 8888, 8080\]\}'
5. Adding route mappings
   • (confirmation before operations) cf curl /v2/route_mappings
   • (checking <ROUTE-GUID>s) cf curl /v2/routes and check each guid for routes tcp.bosh-lite.com:1080, tcp.bosh-lite.com:1077, tcp.bosh-lite.com:1088
   • cf curl /v2/route_mappings -X POST -d "\{\"app_guid\": \"$(cf app mpg-tcp --guid)\", \"route_guid\": \"<ROUTE-GUID>\", \"app_port\": 8080\}"
   • cf curl /v2/route_mappings -X POST -d "\{\"app_guid\": \"$(cf app mpg-tcp --guid)\", \"route_guid\": \"<ROUTE-GUID>\", \"app_port\": 7777\}"
   • cf curl /v2/route_mappings -X POST -d "\{\"app_guid\": \"$(cf app mpg-tcp --guid)\", \"route_guid\": \"<ROUTE-GUID>\", \"app_port\": 8888\}"
   • (confirmation after operations) cf curl /v2/route_mappings
6. Validating behavior
   • curl -k http://tcp.bosh-lite.com:1077
   • curl -k http://tcp.bosh-lite.com:1080
   • curl -k http://tcp.bosh-lite.com:1088

Is this feature disabled? I understand that the API is experimental or sth but IMO this feature is absolutely crucial

@ciberklied @mgrzejszczak - are you all actively using this feature currently?

Is there a way to get HTTP and TCP traffic to the same app without this feature?

The APIs described in these docs are now supported and stable.

HTTP and TCP traffic can be routed to the same app using this feature.

The APIs mentioned in this demo are incomplete, experimental, unsupported and may be removed at any time. We abandoned this implementation after determining the design was unnecessarily complex, and haven't prioritized removing or replacing it. Please send use cases for application receiving requests on multiple ports to me, as this helps us prioritize delivering a supported solution.

Thank you.

Hello!

I have a mongo docker image, I push it to SAP Cloud Foundry, how can I expose 27017 port to access from outside? Any idea?

Thanks
