Can't access web interface for docker image

[OliverCole]

Latest docker, Windows 7, following the docs at https://eclipse-che.readme.io/docs/install-using-docker.

After running the image, I can't connect to localhost:8080, or any other mapped port. I suspect it relates to these errors!

Hi. First, the docker image that is on the Che site is outdated. We do not yet have automation to support re-generation of the image. The image is for version 3.12.x, which is part of the old release train, and not part of the next generation platform for Eclipse. The next gen stuff is pre-alpha as part of the 4.0 branch.

Specific to the docker run - did you do this with root privs or another user?

If you'd like to test the latest stuff, we need you to build from source. It's relatively easy to do if you have 10 minutes. Requires Java 8 and Maven 3.1.1+.

git clone http://github.com/codenvy/che
cd che
git checkout 4.0
cd assembly-sdk
mvn clean install
cd ..
./che.sh run
http://localhost:8080

We'll update the docker image for the alpha soon.

Hi,

The version itself does not matter here.

You took an example of mapping it to 9000 port, so che should be available at localhost:9000

Also, the image has to be run in a privileged mode, to support Docker in Docker.

So, docker run --privileged -it -p 8080:8080 -p 49152-49162:49152-49162 codenvy/che should work

[OliverCole]

When I use --privileged the errors disappear, but I still can't access the web interface.

[TylerJewell]

This is an older version.  Can you tell us what you see with localhost:9000/che and also localhost:9000/dashboard 
Thanks.

I met this same issue. You should not connect to localhost, but the ip which the virtual machine provided, for me, it's 192.168.99.100 in the welcome message from "Docker Quickstart Terminal":

                        ##         .
                  ## ## ##        ==
               ## ## ## ## ##    ===

             \    \         __/
              \____\_______/


docker is configured to use the default machine with IP 192.168.99.100
For help getting started, check out the docs at https://docs.docker.com

This is really confused me who doesn't know docker, in the end I asked for help from some docker expert after several hours of struggling.

Hope to put this information to the installation document

Yes, we'll add a boot2docker section to the installation docs. In this case, you should access VM IP directly, while for OS having a native Docker support it's just localhost.

[freewind]

Seems like boot2docker is deprecated?

https://github.com/boot2docker/boot2docker-cli

Deprecated
This project is officially deprecated in favor of Docker Machine. The code and documentation here only exist as a reference for users who have not yet switched over (but please do soon). The recommended way to install Machine is with the Docker Toolbox.

You should not connect to localhost, but the ip which the virtual machine provided

That was it - thanks!
