Thomas Eizinger 04499da11e feat(telemetry): grab env and distinct_id from Sentry session (#9801)
At present, our primary indicator as to whether telemetry is active is
whether we have a Sentry session. For our analytics events however, we
currently require passing in the Firezone ID and API url again. This
makes it difficult to send analytics events from areas of the code that
don't have this information available.

To still allow for that, we integrate the `analytics` module more
tightly with the Sentry session. This allows us to drop two parameters
from the `$identify` event and also means we now respect the
`NO_TELEMETRY` setting for these events except for `new_session`. This
event is sent regardless because it allows us to track, how many on-prem
installations of Firezone are out there.

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. Ensure the FIREZONE_TOKEN=<gateway_token> environment variable is set securely in your Gateway's shell environment. The Gateway requires this variable at startup.
  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.
