Introduction 

It’s not easy to check containers status with top/htop. With ctop, now we can check/display all containers status with top-like interface!

Installation 

ctop is developed by Go, all we need to do is download and put binary to the right place, then we can start to monitor containers status! (Support Linux and macOs)

Linux 

$ wget https://github.com/bcicen/ctop/releases/download/v0.4.1/ctop-0.4.1-linux-amd64 -O ctop
$ sudo mv ctop /usr/local/bin/
$ sudo chmod +x /usr/local/bin/ctop

Mac Os X 

$ curl -Lo ctop https://github.com/bcicen/ctop/releases/download/v0.4.1/ctop-0.4.1-darwin-amd64
$ sudo mv ctop /usr/local/bin/
$ sudo chmod +x /usr/local/bin/ctop

Docker 

Official also support running ctop in container. Just mount host docker socket as a volume into container, so that ctop can communicate with docker process.

$ docker run -ti -v /var/run/docker.sock:/var/run/docker.sock quay.io/vektorlab/ctop:latest

CTOP Usage 

We need to specify where is the docker host first before using it.

$ export DOCKER_HOST=tcp://127.0.0.1:4243
$ ctop

Keybindings 

Following are keybindings list provided now.

keybindings f 

Use f to filter containers and find our desired ones. (Number is not support(2017/03/12))

keybindings s 

Use s to sort containers with selecting fileds
