Running insecure registry via Podman, starting on reboot

This is quite simple, there is a lot of docs out there, so just to put it on one place I do not need to look for it next time I want to install this "full stack solution":

• Setup Docker Container Registry with Podman & Let’s Encrypt SSL
• Starting Containers with systemd

Install Podman

# subscription-manager repos --enable rhel-7-server-extras-rpms
# yum install podman

Start and configure registry

# lvcreate data_perf54 --size 25G --name docker_registry
# mkfs.xfs /dev/mapper/data_xyz-docker_registry
# tail -n 1 /etc/fstab
/dev/mapper/data_xyz-docker_registry /var/lib/registry xfs defaults 0 0
# mount /var/lib/registry
# podman run --privileged -d --name registry-srv -p 5000:5000 -v /var/lib/registry:/var/lib/registry registry:2

Surviving reboot

# cat /etc/systemd/system/registry-srv-container.service
[Unit]
Description=Docker registry container

[Service]
Restart=always
ExecStart=/usr/bin/podman start -a registry-srv
ExecStop=/usr/bin/podman stop -t 30 registry-srv

[Install]
WantedBy=local.target
# systemctl enable registry-srv-container.service
# systemctl restart registry-srv-container.service
# systemctl status registry-srv-container.service

Push to it

# grep 'registries.insecure' -A 1 /etc/containers/registries.conf 
[registries.insecure]
registries = ['your_hostname:5000']
# podman pull busybox
# podman tag docker.io/library/busybox $( hostname ):5000/busybox
# podman push $( hostname ):5000/busybox

See registry's API

# curl -s "http://$( hostname ):5000/v2/_catalog?n=100" | json_reformat 
{
    "repositories": [
        "busybox"
    ]
}
