flyedge.service runs /opt/fly/current/fly-edge After= and Requires= flysim.service, with its metrics on loopback :9102 and a ConditionPathExists so a release without the binary leaves it inactive. It is in no target and 07-enable.sh does not enable it; the header has the switch and the way back. build-flysim.sh also builds fly-edge beside the flysim binary and package-release.sh ships it when present. 05-deploy.sh writes FLY_FEED_VIA (default direct) into fly.env, flysim.service names FLY_BUS_DIR=/run/fly/bus and tmpfiles creates it. Watchdog check 2 reads the feed counters from whoever serves the feed: flyedge when fly.env says bus. lint.sh holds all of that, and drives check 2's choice against a fixture. |

infra/env — the env files, and why the real ones are not here
infra/env/example.env is the only env file in this repo. It lists every knob the
infra/ scripts read, with placeholder values and the comments that say what each one
costs. It is a template: it will not deploy anything.
The real env files live in the operator's infra repo, not here. This repo is public,
and a real env file names the host, the container id, the LAN address, the Twitch channel
and the pass entry that holds the stream key. Keeping them out is the point of the
de-PII sprint (inventory in the operator's infra repo); infra/tests/lint.sh refuses those
patterns on every run.
Handing a script an env file from outside the repo
Every script takes the env file as its first argument, and that argument may be any absolute or relative path — nothing resolves it against this directory:
# on the host, as root
install -d -m 0750 /etc/fly/env # or wherever you keep them
# ... write the real file to /etc/fly/env/fly-pokemon.env ...
infra/provision.sh /etc/fly/env/fly-pokemon.env
infra/05-deploy.sh /etc/fly/env/fly-pokemon.env <release-tarball>
infra/verify.sh /etc/fly/env/fly-pokemon.env
Or set FLY_ENV_DIR once and pass a bare name; load_env resolves an argument that is
not itself a readable file against that directory:
export FLY_ENV_DIR=/etc/fly/env
infra/provision.sh fly-pokemon.env
infra/verify.sh fly-pokemon.env
FLY_ENV_DIR is only a convenience for typing. If the file is not found either way the
script dies naming both paths it tried.
Keeping a real env in step with this template
example.env changes whenever a knob is added. After pulling a flybrain bump:
diff <(grep -oE '^[A-Za-z_][A-Za-z0-9_]*=' infra/env/example.env | sort -u) \
<(grep -oE '^[A-Za-z_][A-Za-z0-9_]*=' /etc/fly/env/fly-pokemon.env | sort -u)
Lines only on the left are knobs the real file has not been told about yet. load_env
requires CTID, HOSTNAME, IP, GAME and PUSH_TARGET; ROLE defaults to dev.
What must never be in an env file
Secrets. PASS_KEY holds the name of a pass entry, never a key. The Twitch app
id/secret arrive as the systemd credential twitch-app, installed by
infra/06-secrets.sh from pass on the operator box; the OAuth tokens live in the
container as /var/lib/flybridge/tokens.json, mode 0600. ROM_SHA256 is a digest, and
the ROM it describes is never committed, copied into the repo, or shown on stream.
