Thomas Eizinger 038aa6b590 feat(gateway): support systemd credentials (#10538)
For more permanent Gateway installations, or ones that are managed
through something else other than our install script, it is useful to
define the Gateway's token outside the systemd unit file.

Systemd provides support for credentials via the `LoadCredential` and
`LoadCredentialEncrypted` instructions. We just need a tiny bit of glue
code in the Gateway to actually use that if it is set.

gateway

This crate houses the Firezone gateway.

Building

You can build the gateway using: cargo build --release --bin firezone-gateway

You should then find a binary in target/release/firezone-gateway.

Running

The Firezone Gateway supports Linux only. To run the Gateway binary on your Linux host:

  1. Generate a new Gateway token from the "Gateways" section of the admin portal and save it in your secrets manager.
  2. Provide the token to the Gateway using one of these methods:
    • Set the FIREZONE_TOKEN=<gateway_token> environment variable
    • Set a systemd credential named FIREZONE_TOKEN.
  3. Set FIREZONE_ID to a unique string to identify this gateway in the portal, e.g. export FIREZONE_ID=$(head -c 32 /dev/urandom | sha256sum | cut -d' ' -f1). The Gateway requires this variable at startup. We recommend this to be a 64 character hex string.
  4. Now, you can start the Gateway with:
firezone-gateway

If you're running as a non-root user, you'll need the CAP_NET_ADMIN capability to open /dev/net/tun. You can add this to the gateway binary with:

sudo setcap 'cap_net_admin+eip' /path/to/firezone-gateway

Ports

The gateway requires no open ports. Connections automatically traverse NAT with STUN/TURN via the relay.
