PODMAN: How to Setup Podman Registry Instance Running On Non SSL HTTP protocol?

Following are steps to Setup Podman Registry Instance Running On Non SSL HTTP protocol?

1) Install podman (if its not already installed).

dnf -y install podman

2) Run podman instance by pulling container image. In this case we are pulling registry image from Oracle Container registry (OCR)

sudo podman run -d --name ock-registry \

-p 5000:5000 \

-v /var/lib/registry:/var/lib/registry:Z \

--restart=always \

-e REGISTRY_AUTH="" \

container-registry.oracle.com/os/registry:v2.7.1.1

3) Validate that the podman instance is running and podman registry image is pulled. 

For this use below commands.

podman ps -a

podman images

Below is sample outputs of above commands.

CONTAINER ID  IMAGE                                               COMMAND               CREATED        STATUS        PORTS                   NAMES

4) For connecting from the clients to private registry running on HTTP, set insecure registry.

For this follow below steps.

Edit /etc/containers/registries.conf file and insert the following text at the end of the file.

[[registry]]

location = "localhost:5000"

insecure = true

Reload daemon and restart podman service after the change.

systemctl daemon-reload

systemctl restart podman
