The container usesocat to bound Docker socket to a TCP port, so that I could avoid to changethehttp.Post part in the Go server to talk directly to a UNIX socket.

You can launch the container in this way:

docker run \--name docker-exec-web-console \-p 9999:8888 \-v /var/run/docker.sock:/var/run/docker.sock \bitbull/docker-exec-web-console

Then you can reach the console at the urlhttp://localhost:9999

It's possible to pass a context path to which the container will responds, usingCONTEXT_PATHenvironment variable:

docker run \--name docker-exec-web-console \-p 9999:8888 \-e "CONTEXT_PATH=/webconsole" \-v /var/run/docker.sock:/var/run/docker.sock \bitbull/docker-exec-web-console

With the above example, the console will be reachable at the urlhttp://localhost:9999/webconsole

You can select the container to exec into passing its id directly viacid querystring parameter (eg.http://localhost:9999?cid=<container id> ) or in the prompt that will show at page load.

You can pass the command to execute passing it viacmd querystring parameter (eg.http://localhost:9999?cid=<container id>&cmd=/bin/sh ), otherwise it default to/bin/bash.

The image is based onalpine:latest, so you need to compile the server for Linux with all libsstatically linked:

CGO_ENABLED=0 GOOS=linux go build -a -installsuffix cgo -o main .

then you can build as usual:

docker build -t bitbull/docker-exec-web-console .
