Overview

This application note explains how to use the docker in the Emcraft software distribution for the Renesas RZ/V2H SoC.

Running Docker

To start the docker daemon run:

user@rzv2hevkalpha:~$ sudo systemctl start docker

To check everything is working, run the docker info:

user@rzv2hevkalpha:~$ sudo docker info

Running “Hello, world!”

Pull and run the first container, hello-world:

user@rzv2hevkalpha:~$ sudo docker run hello-world

The docker would download the hello-world image and run it:

Unable to find image 'hello-world:latest' locally
latest: Pulling from library/hello-world
70f5ac315c5a: Pull complete 
Digest: sha256:3155e04f30ad5e4629fac67d6789f8809d74fea22d4e9a82f757d28cee79e0c5
Status: Downloaded newer image for hello-world:latest

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.
    (arm64v8)
 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:
 https://hub.docker.com/

Post-install Configuration

If you want to run docker without root privileges, add user to the docker group:

user@rzv2hevkalpha:~$ sudo usermod -aG docker $USER

After you log out and log back, you can run docker commands without sudo:

user@rzv2hevkalpha:~$ user@imx8mpnavq:~$ docker ps
CONTAINER ID   IMAGE     COMMAND   CREATED   STATUS    PORTS     NAMES
user@rzv2hevkalpha:~$ docker ps -a
CONTAINER ID   IMAGE         COMMAND    CREATED         STATUS                     PORTS     NAMES

user@rzv2hevkalpha:~$ docker image ls
