Registry Setup Linode Docker | Guide

Did you know that we need Docker installed and configured to run a registry on a Linode?

Our experts have put together this guide to get you started.

1. First, we have to enable the Docker repository for our system’s package manager. The repository is usually enabled once we install the Docker engine.
2. Next, update the package manager, and install the Docker Compose plugin as seen below:
   • For Debian and Ubuntu systems

     sudo apt update
sudo apt install docker-compose-plugin
   • For CentOS, Fedora, and other RPM-based distributions:

     sudo yum update
sudo yum install docker-compose-plugin

Now, we can pull the container, you can run the following command:

$ docker run -d -p 5000:5000 --restart=always --name registry registry:2

We can check if we were successful with this command:

$ docker ps

Furthermore, we can let our image be run by Docker instances down the line:

$ docker tag image-name registrys-IP-address:5000/image-name

In case we run into an error because our registry responded with an HTTP message and not HTTPS, we can add the following to our /etc/docker/daemon.json file:


{
"insecure-registries" : ["<registry's-IP-address>:5000"]
}

Let us know in the comments if you need further help.
