## Handling the forge ## Installation
You can use the `forge.sh` to **setup**, **heat-up** or **cool-down** the forge. ### Pre-requisites
As many tools as possible are built-in but still we rely on some pre-requisites.
These tools and service are necessary to get started:
- [Podman](https://podman.io/)
Must be installed and a [podman socket](https://github.com/containers/podman/blob/main/docs/tutorials/socket_activation.md)
in the user space must be active.
- [js](https://jqlang.github.io/jq/)
Must be installed. It it currently needed in the setup process to parse certain parameters
automatically for you
- The kernel parameter `net.ipv4.ip_unprivileged_port_start` must be set to `80`
This is because of podman's [shortcoming](https://github.com/containers/podman/blob/main/rootless.md#shortcomings-of-rootless-podman)
to bind to ports `< 1024`. Our reverse-proxy is listening on port `80` and `443`
for incoming traffic.
- [OpenSSH](https://www.openssh.com/)
Must be installed and the service activated. Ansible needs this to execute all the fancy
commands on your host for you.
### Setup / Heat-Up / Cool-Down
For the initial setup and maintenance of the forge you can use the `forge.sh` script:
