Set Up an HTTP User Registry

Prerequisites: Ensure that the server has an active internet connection.

To deploy a container registry using Podman, do the following:

1. Create a registry storage directory.

   mkdir -p /root/data
   chown -R 1000:1000 /root/data
   

2. Start the registry container.

   sudo podman run -d --name user_registry  --restart=always -p 3445:5000 -v /root/data:/var/lib/registry:Z docker.io/library/registry:2
   

3. Open firewall port. Allow inbound traffic on port 3445.

   sudo firewall-cmd --add-port=3445/tcp --permanent
   sudo firewall-cmd --reload
   

Note

Use a port other than 5000 when exposing the registry (for example, 3445), as port 5000 is already occupied by Omnia containers.

The registry is now accessible at: http:// <PUBLIC_IP>:3445/v2/.

Tag and Push an Image to the Registry

To pull an image, tag it for your local registry, and push the changes, do the following:

1. Pull the image.

   podman pull docker.io/library/nginx:1.25.2-alpine-slim
   

2. Tag the image. Replace <Public_IP> with your server’s Public IP.

   podman tag docker.io/library/nginx:1.25.2-alpine-slim <Public_IP>:3445/library/nginx:1.25.2-alpine-slim
   

3. Push the image to the registry. Because this is an HTTP registry, disable TLS verification.

   podman push <Public_IP>:3445/library/nginx:1.25.2-alpine-slim --tls-verify=false
