I have a setup of Azure VM scaleset, each Linux VM running java spring boot app on a specific port (8070). I need to use a domain with https on application gateway and use Linux VMSS with java app as backend pools.

I am aware this can be done with azure lb but I need to use SSL. If this is possible with a gateway, what would be configurations for 'listeners', 'rules' and 'HTTP settings'

I saw a question which is relevant to mine, but I need much more help.

this is not possible with lb unless your app listens on https (so it needs a certificate). its possible to do SSL offloading on the app go or do end-to-end SSL. this is the official article to configure SSL offloading, this one is for e2e SSL.

basically, you need to create SSL and create a listener that's using that SSL certificate. probe behaviour doesn't change (compared to lb probe) unless you are doing e2e SSL.

  • I will go with ssl offloading on appgw. My problem how do I manage the http listener and rules and http settings for my VM scalesets which all have Java app running on 8070 port. Commented Jan 19, 2019 at 8:14
  • i dont see a question in your statement. read the official article. scale sets do not differ from vms in this regard Commented Jan 19, 2019 at 8:30
  • Yeah I see that , probably I didn't phrase my question properly. What would be the 'http settings' , 'rules' and 'listeners' if vmss run the app on 8070 port. How do I forward requests from appgw to vmss in terms of settings on appgw to be configured Commented Jan 19, 2019 at 8:59
  • follow the article and see for yourself? it tells you how to do that from scratch Commented Jan 19, 2019 at 9:01
  • I am afraid i also went through the (docs.microsoft.com/en-us/azure/application-gateway/…) but there's an example on nginx on vmss which runs on port 80, but is is possible i hit appgw on https://<appgw>.domain.com which hits backend pools on java app on port 8070. What would be listener and http settings? Commented Jan 19, 2019 at 18:17
