container-web-tty

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

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 \
    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 --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 \
    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 --rm -ti --name 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

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

Features

• it works

Show-off

List the containers on your machine:

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