I'm using the latest CentOS release on my RPi and I'd like to start playing with docker. I tried following the official instructions here. I installed the dependencies and enabled the repo, but when I tried to run sudo yum install docker-ce, I got the following error:

https://download.docker.com/linux/centos/7/armhfp/stable/repodata/repomd.xml: [Errno 14] HTTPS Error 404 - Not Found

Does this mean there is no docker build for CentOS on the RPi? If not, what's the easiest way to make this happen?

If You need install Docker at RPI3 + CentOS, run next command

sudo yum install docker -y

add Docker to startup - sudo systemctl enable docker.service Run Docker - systemctl start docker

Not many OS distros package docker for the CPU architecture of the RaspberryPi - armhf. Your error indicates that CentOS doesn't have a docker package for you.

You will need to install it like this:

curl -sSL https://get.docker.com | sh

This is further explained in this raspberrypi.org article: https://www.raspberrypi.org/blog/docker-comes-to-raspberry-pi/
