Before removing from apply_hotfix function first verify that older installs < 3.1.0 are still upgradable when referencing 'so/0013_input_lumberjack_fleet.conf' via pillar. Failure to do so will prevent logstash from starting
The manager's /etc/salt/minion (written by so-functions:configure_minion)
has no file_roots, so salt-call --local falls back to Salt's default
/srv/salt and fails with "No matching sls found for 'postgres.telegraf_users'
in env 'base'". || true was silently swallowing the error, which meant the
DB roles for the pillar entries just populated by the so-telegraf-cred
backfill loop never actually got created.
Route through salt-master instead; its file_roots already points at the
default/local salt trees.
pillar/top.sls now references postgres.soc_postgres / postgres.adv_postgres
unconditionally, but make_some_dirs only runs at install time so managers
upgrading from 3.0.0 have no local/pillar/postgres/ and salt-master fails
pillar render on the first post-upgrade restart. Similarly, secrets_pillar
is a no-op on upgrade (secrets.sls already exists), so secrets:postgres_pass
never gets seeded and the postgres container's POSTGRES_PASSWORD_FILE and
SOC's PG_ADMIN_PASS would land empty after highstate.
Add ensure_postgres_local_pillar and ensure_postgres_secret to up_to_3.1.0
so the stubs and secret exist before masterlock/salt-master restart. Both
are idempotent and safe to re-run.
The old flow had two writers for each per-minion Telegraf password
(so-minion wrote the minion pillar; postgres.auth regenerated any
missing aggregate entries). They drifted on first-boot and there was
no trigger to create DB roles when a new minion joined.
Split responsibilities:
- pillar/postgres/auth.sls (manager-scoped) keeps only the so_postgres
admin cred.
- pillar/telegraf/creds.sls (grid-wide) holds a {minion_id: {user,
pass}} map, shadowed per-install by the local-pillar copy.
- salt/manager/tools/sbin/so-telegraf-cred is the single writer:
flock, atomic YAML write, PyYAML safe_dump so passwords never
round-trip through so-yaml.py's type coercion. Idempotent add, quiet
remove.
- so-minion's add/remove hooks now shell out to so-telegraf-cred
instead of editing pillar files directly.
- postgres.telegraf_users iterates the new pillar key and CREATE/ALTERs
roles from it; telegraf.conf reads its own entry via grains.id.
- orch.deploy_newnode runs postgres.telegraf_users on the manager and
refreshes the new minion's pillar before the new node highstates,
so the DB role is in place the first time telegraf tries to connect.
- soup's post_to_3.1.0 backfills the creds pillar from accepted salt
keys (idempotent) and runs postgres.telegraf_users once to reconcile
the DB.
