Not able to open WEB UI of the application running within docker container


(Hpeaviator) #1

I am able to successfully build my Controller Docker image with base Ubuntu platform, along with prerequisite software and set environment and start the essential processes within the Docker container. But am unable to open the WEB UI for the Controller running in the docker container from the 172.17.0.2 or host IP I get 404 error,
I access the WEB UI using HTTPS protocol with URL - https://<Host_ip>:8443/sdn/ui from a browser.

Following is the error I get when I do a wget from the container,

PS: I run the container with the following command,

What is it that am missing to access the WEB UI of the controller from any browser? I always get 404 error?

That sounds to me like all of the Docker networking parts are correct: the browser is successfully connecting to the application port and exchanging data. Docker doesn’t do anything special to HTTP streams, and especially not encrypted ones. So something in your application setup isn’t right.

Am using HTTPS protocol here is there something that i need to ensure the same query that works on a normal are metal system works on docker setup? Why is that the service that is available an running with the docker not visible when accessed from the host system?

Is there any configuration that I need to make to get that service working / accessible from https ?

The service is accessible. You’re establishing the network connection, you’re getting through the SSL handshake, you’re sending an HTTP request, and you’re getting an HTTP response back.

That the response happens to be “HTTP/1.1 404 Not Found” isn’t really anything Docker has any control over.
