Container web TTY

中文

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.

Usage

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 -dti --restart always --name container-web-tty \
    -p 8080:8080 \
    -v /var/run/docker.sock:/var/run/docker.sock \
    wrfly/container-web-tty

# tail logs
docker logs -f container-web-tty

Using kubernetes

Or you can mount the kubernetes config file:

docker run -dti --restart always --name container-web-tty \
    -p 8080:8080 \
    -e WEB_TTY_BACKEND=kube \
    -e WEB_TTY_KUBE_CONFIG=/kube.config \
    -v ~/.kube/config:/kube.config \
    wrfly/container-web-tty

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.

Remote

Host 192.168.66.1 and 192.168.66.2 both running:

docker run -dti --restart always --name container-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 \
    wrfly/container-web-tty

Notes:

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

Local

docker run -dti --restart always --name container-web-tty \
    -p 8080:8080 \
    -e WEB_TTY_BACKEND=grpc \
    -e WEB_TTY_GRPC_AUTH=96ssW0rd \
    -e WEB_TTY_GRPC_SERVERS=192.168.66.1:8090,192.168.66.2:8090 \
    wrfly/container-web-tty

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

Features

• [x] it works
• [x] docker backend
• [x] kubectl backend
• [x] beautiful index
• [x] support docker ps options
• [x] start|stop|restart container(docker backend only)
• [x] proxy mode (client -> server's containers)
• [x] auth(only in proxy mode)
• [x] TTY timeout (idle timeout)
• [x] history audit (just cat the history logs after enable this feature)
• [x] real time sharing (like screen sharing)
• [x] container logs (click the container name)
• [x] exec arguments (append an extra "?cmd=xxx" argument in URL)
• [x] connect to gRPC servers via HTTP/Socks5 proxy

Audit exec history and container outputs

docker run -dti --restart always --name container-web-tty \
    -p 8080:8080 \
    -e WEB_TTY_AUDIT=true \
    -v `pwd`/container-audit:/audit \
    -v /var/run/docker.sock:/var/run/docker.sock \
    wrfly/container-web-tty

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

Real-time sharing

You can always share the container's inputs and outputs with others via the exec link, just share the /exec/<exec-ID> to them!

Collaborate

docker run -dti --restart always --name container-web-tty \
    -p 8080:8080 \
    -e WEB_TTY_COLLABORATE=true \
    -v /var/run/docker.sock:/var/run/docker.sock \
    wrfly/container-web-tty

By enabling this feature, once you exec into the container, you can share your process with others, that means anyone got the shareable link would type the command to the tty you are working on. You can edit the same file, type the same code, in the same TTY! Just share the exec link to your friend!

Show-off

List the containers on your machine:

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

/bin/bash:
