can't login, error: server is not running

[NickZengXL]

I want to run yang-exploer on my docker toolbox, following these steps:

1. docker pull robertcsapo/yang-explorer
2. docker run -d --name yangexploer -p 8088:8088 robertcsapo/yang-explorer Then i can access http://localhost:8088/static/YangExplorer.html, also can create new account. But i can't login with new account, neither with guest/guest. The error is : server is not running

[NickZengXL]

This is my docker info:

docker@default:~$ docker images
REPOSITORY                                              TAG                 IMAGE ID            CREATED             SIZE

docker@default:~$ docker ps

[robertcsapo]

could you provide a screenshot of "server is not running" and docker logs --tail 20 yangexploer from your docker host?

[NickZengXL]

docker logs:

[robertcsapo]

Are you sure traffic is routed to your container? Because you should se more HTTP requests.

I've followed your steps and it works for me.

• docker run -d --name yangexploer -p 8088:8088 robertcsapo/yang-explorer
• Firefox -> http://localhost:8088/static/YangExplorer.html
  • Logged in as guest/guest
• docker logs --tail 20 yangexploer

Output:

I ran continer yang-explorer in my docker toolbox on Windows 10. Then I can access yang-explorer web with chrome on my Windows 10, using http://docker-vm-ip:8088/static/YangExplorer.html not http://localhost:8088/static/YangExplorer.html Because docker toolbox will create a virtual machine in Vbox, and the network configuration is HOST and NAT mode. So, I can't use localhost to access yang-explorer web.

But then I can't logged in with any account.

================ amendment: I use 8088, not 8080. Here is a typing error.

[robertcsapo]

Your starting this container on port 8088 and not port 8080 Based on your output

docker@default:~$ docker ps
CONTAINER ID        IMAGE                                 COMMAND                  CREATED             STATUS              PORTS                    NAMES
256d6cc92c08        robertcsapo/yang-explorer             "/bin/sh -c 'bash sta"   3 seconds ago       Up 2 seconds        0.0.0.0:8088->8088/tcp   yangexploer

If you can access port 8080. Then it's not in the same Docker Host.

Try if you can reach the container by it's ip-address docker inspect yangexploer | grep -i ipaddress

[rustogi]

@NickZengXL based on your earlier responses, I am assuming that chrome is running natively but docker is running in virtual box, if so can you indicate how many nics do you have in vbox vm. Also assuming you have just 1 Nic and that is doing NAT, you would need to add a port forwarding rule in virtual box so traffic to port 8088 is delivered into the guest.

Hi, i have the same issue, i can load the yang-explorer ui on:

http://127.0.0.1:8088/static/YangExplorer.html

However when trying to login it says: "Server is not running"

I built my own docker container for this (docker for mac), and also pulled robertcsapo/yang-explorer but both containers give me the same error message.

On the yang-explorer server, the only messages i see are:

Quit the server with CONTROL-C.

Much appreciate your help!

@sandstonewater could you try http://localhost:8088 ? If that doesn't work. Please post full debug

like this

Hi, thanks for your quick reponse. I tried http://localhost:8088 but still doesnt work, same error message. When the webui loads up, there is always a spinning clock, it never changes to a pointer. Below is the full debug.
