Sets in libs/systemd.py:18 are sorted alphabetically. The current
output is correct by accident — host.env < web.env, host.env < /var.
Adding a third path later would silently reorder. Tuples preserve
insertion order; generate_unitfile() iterates them the same way.
Environment (HOME=, PATH=) stays a set: each line is an independent
KEY=VALUE assignment, order is irrelevant.
Translates the remaining three unit files from left4me/deploy/files/.
Server template carries the full hardening + cgroup/IO/Mem keys
verbatim. Slices need the bundles/systemd .slice support added in
prior commit.
Translates left4me/deploy/files/usr/local/lib/systemd/system/left4me-web.service
into a Python dict consumed by bundles/systemd/. Two changes vs. the
shell-deploy unit:
- --bind 0.0.0.0:8000 -> 127.0.0.1:8000 (nginx terminates TLS in front)
- workers/threads are templated from left4me/gunicorn_{workers,threads}
(defaults: 1 worker + 32 threads — same as the static unit)
Mirrors deploy-test-server.sh:233-242 + :329-333. Single pip command
installs both editable packages (l4d2host + l4d2web) from the same
checkout. Alembic and seed-overlays run as the left4me user with
JOB_WORKER_ENABLED=false sourced from web.env.
A malformed /etc/sudoers.d/left4me would lock sudo on the target
(blast radius: every other bundle using sudo at apply time). bw's
file: items support test_with, which runs the supplied command on the
locally-rendered file before transfer. Use it to gate the sudoers
file on visudo -cf — analogous to the visudo -cf check the original
deploy script ran inline (deploy-test-server.sh:186).
Bundle metadata declares port_range_start/end in defaults, but the
running app (l4d2web/config.py:34-35) reads them from
LEFT4ME_PORT_RANGE_START/END env vars. Without these in web.env, the
bundle's metadata values were dead code and the app fell back to its
own hardcoded defaults. Wiring them through closes the loop.
SECRET_KEY pulled from node metadata (set via !32_random_bytes_as_base64_for:
in the node file). SESSION_COOKIE_SECURE flips to true since nginx fronts
gunicorn with TLS.
Copied verbatim from left4me/deploy/files/. Helpers are the trust unit
the sudoers rules grant access to; left as static files (not generated)
so the audit trail stays grep-able. Modes/owners are set via items.py
in the next commit.
