Set Up an HTTP User Registry

Prerequisites

Procedure

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
