DNS Records

Before you can create a Caddyfile you need records that point to your server.

You can either create them manually in your DNS provider of choice or use the provided ddns service:

1. Update the ddns caddy records
2. Run the caddy ansible playbook

Install Caddy

Ansible

You'll need a secrets/Caddyfile with your caddy config.

secrets/Caddyfile example:

https://something.reeseapps.com:443 {
    reverse_proxy internal.reeselink.com:8000
}

https://something-else.reeseapps.com:443 {
    reverse_proxy internal-other.reeselink.com:8080
}

The playbook limits the installer to hosts: caddy so make sure you have a caddy host in your inventory.

Now you can install the Caddy service with something like:

ansible-playbook \
-i ansible/inventory.yaml \
active/podman_caddy/install_caddy.yaml

See ansible playbook install_caddy.yaml

Manual

As root

mkdir /etc/caddy
vim /etc/caddy/Caddyfile

Caddy will automatically provision certificates if the server DNS points to the correct IP and is accessible on the ports specifified. All you need to do is put https in the caddy conf.

Example:

# Gitea
https://gitea.reeseapps.com:443 {
    reverse_proxy podman.reeselink.com:3000
}

# Jellyfin
https://jellyfin.reeseapps.com:443 {
    reverse_proxy podman.reeselink.com:8096
}
