Container web TTY

Tired of typing docker ps | grep xxx && docker exec -ti xxxx sh ? Try me!

Although I like terminal, I still want a better tool to get into the containers to do some debugging or checking. So I build this container-web-tty. It can help you get into the container and execute commands via a web-tty, based on yudai/gotty with some changes.

Both docker and kubectl are supported.


Of cause you can run it by downloading the binary, but thare are some Copy-and-Paste ways.

Using docker

You can start container-web-tty inside a container by mounting docker.sock:

docker run --rm -ti --name web-tty \
    -p 8080:8080 \
    -v /var/run/docker.sock:/var/run/docker.sock \

Using kubernetes

Or you can mount the kubernetes config file:

docker run --rm -ti --name web-tty \
    -p 8080:8080 \
    -e WEB_TTY_BACKEND=kube \
    -e WEB_TTY_KUBE_CONFIG=/kube.config \
    -v ~/.kube/config:/kube.config \

Using local <-> remote (gRPC)

You can deploy container-web-tty in remote servers, and connect to it via a local container-web-tty. They use gRPC for communication.

This is useful when you cannot get the remote servers or there are more than one server that you need to connect to.


Host and both running:

docker run --rm -ti --name web-tty \
    -p 8080:8080 \
    -p 8090:8090 \
    -e WEB_TTY_GRPC_PORT=8090 \
    -e WEB_TTY_GRPC_AUTH=96ssW0rd \
    -v /var/run/docker.sock:/var/run/docker.sock \


  • You can disable the HTTP server by setting WEB_TTY_PORT=-1
  • The WEB_TTY_GRPC_AUTH must be the same between all hosts


docker run --rm -ti --name web-tty \
    -p 8080:8080 \
    -e WEB_TTY_BACKEND=grpc \
    -e WEB_TTY_GRPC_AUTH=96ssW0rd \

Now you will see all the containers of all the servers via http://localhost:8080

Keyboard Shortcuts (Linux)

  • Cut the word before the cursor Ctrl+w => You cannot do it for now (I'll working on it for Ctrl+Backspace, but I know little about js)
  • Copy: Ctrl+Shift+c => Ctrl+Insert
  • Paste: Ctrl+Shift+v => Shift+Insert


  • it works
  • docker backend
  • kubectl backend
  • beautiful index
  • start|stop|restart container(docker backend only)
  • environment injection (extra params)
  • proxy mode (client -> server's containers)
  • auth(only in proxy mode)
  • TTY timeout (idle timeout)
  • history audit (just cat the history logs after enable this feature)
  • real time sharing (like screen sharing)
  • container logs (just click the container name)
  • exec arguments (append an extra "?cmd=xxx" argument to exec URL)

Audit exec history and container outputs

docker run --rm -ti --name web-tty \
    -p 8080:8080 \
    -e WEB_TTY_AUDIT=true \
    -v `pwd`/container-logs:/log \
    -v /var/run/docker.sock:/var/run/docker.sock \

After you exec some commands, you will see the inputs and outputs under the container-logs directory, you can use cat or tail -f to see the changes.

Real-time sharing

docker run --rm -ti --name web-tty \
    -p 8080:8080 \
    -e WEB_TTY_SHARE=true \
    -v /var/run/docker.sock:/var/run/docker.sock \

By enabling this feature, you can share the container's inputs and outputs with others via the share link (click the container's image to get the link).


List the containers on your machine:


It will execute /bin/sh if there is no /bin/bash inside the container:
