Docker Container

Install Docker

Download installation script:

curl -fsSL -o

Run script with root privileges:

sudo sh

Add the pi user to the docker group:

sudo usermod -aG docker pi

For the group change to work, you have to log out and log in again.

Check if the installation worked:

docker ps

Run the hello-world test container:

docker run hello-world


pi@raspberrypi:~ $ docker run hello-world
Unable to find image 'hello-world:latest' locally
latest: Pulling from library/hello-world

Hello from Docker!
This message shows that your installation appears to be working correctly.

To generate this message, Docker took the following steps:
 1. The Docker client contacted the Docker daemon.
 2. The Docker daemon pulled the "hello-world" image from the Docker Hub.
 3. The Docker daemon created a new container from that image which runs the
    executable that produces the output you are currently reading.
 4. The Docker daemon streamed that output to the Docker client, which sent it
    to your terminal.

To try something more ambitious, you can run an Ubuntu container with:
 $ docker run -it ubuntu bash

Share images, automate workflows, and more with a free Docker ID:

Building a docker image:

mkdir docker-test && cd docker-test
nano Dockerfile

Insert the following into the Dockerfile and save:

FROM ubuntu
RUN apt-get update
RUN apt-get -y upgrade
RUN apt-get install -y screenfetch
ENTRYPOINT ["/usr/bin/screenfetch"]

Create new docker image:

docker build . --tag myimage:test

Result on successful build:

Successfully built 60d9a33b54f6
Successfully tagged myimage:test

Create and run a new container:

docker run myimage:test -E


pi@raspberrypi:~/docker-test $ docker run myimage:test -E
