Visualize your Raspberry Pi containers with Portainer or UI for DockerMon, Oct 31, 2016
At home I use some Raspberry Pi’s for some home network services, and I run these services inside Docker containers. From time to time I want to see or manage one of these containers. But I’m too lazy to get to my laptop and use the Docker CLI for that. There are two nice Docker UI’s to access your Docker engine with a web browser. Let’s have a look at both.
UI for Docker, formerly known as DockerUI
I have started using the DockerUI, an open source project from Michael Crosby and Kevan Ahlquist. You can find the source code on GitHub at https://github.com/kevana/ui-for-docker.
In my home setup I use Docker Compose to configure how to run my services.
This is my configuration to start the UI so I can reach it on port 80 of the Raspberry Pi.
ui: image: hypriot/rpi-dockerui restart: always volumes: - '/var/run/docker.sock:/var/run/docker.sock' expose: - 9000 ports: - 80:9000
As you can see we provide a Docker image hypriot/rpi-dockerui on the Docker hub so it is very easy to use it in your environment.
So let’s have a look at the dashboard which shows you an overview of your running or stopped containers:
You can click on each container and see more details and so some actions with them like stopping and starting them again.
The UI provides some more views to list for example all local Docker images and information about your Docker engine.
Last week I found portainer.io which also looks very good. They provide Docker images for Linux and Windows,
but not for ARM right now and as well an image for ARM.
The source code is also available on GitHub https://github.com/portainer/portainer and it’s based on the work of DockerUI.
Just use the same Docker Compose sample from above and replace the image name. Killing the old container and running a new one with
docker-compose up -d ui you have Portainer up and running.
The dashboard also gives you an overview of all running containers, all images etc.
In the container list you can see all running and stopped containers as well as some actions you can do with it.
Clicking on one of the running containers you have access to the details, environment variables, port mappings, volumes. You can also access some CPU/memory and network statistics as well as the logs of your container, as well as the processes running inside the container.
If you want to remote control your Raspberry Pi Docker containers from a nice Web UI, then try one of these prebuilt Docker images. Of course be aware that everyone in your home network is able to manipulate your Docker containers with it as there is no login dialog. But for some private projects it is still an advantage to simplify starting and stopping containers from your mobile phone.
