Standalone provider (instagram-standalone OAuth flow) is what the user is trying after the FB-Login path was blocked by their Business Account ad-policy flag. Uses modern scope names (instagram_business_*), so no JS patch needed unlike the FB-Login provider.

# Postiz — social media post scheduler (Instagram Stories + others).

#
|
|
# Chart: oci://ghcr.io/gitroomhq/postiz-helmchart/charts/postiz (v1.0.5)
|
|
# App : ghcr.io/gitroomhq/postiz-app:v2.21.7
|
|
#
|
|
# Layout:
|
|
# - Bundled Postgres + Redis (chart subcharts) — fine for v1.
|
|
# - Local file storage for uploads on a `proxmox-lvm` PVC mounted at /uploads.
|
|
# - JWT_SECRET is sourced from Vault via ESO. The chart's helper-templated
|
|
# Secret name is `<release>-secrets`; we pin `fullnameOverride: postiz` so
|
|
# the Secret resolves to `postiz-secrets`. The chart already mounts that
|
|
# Secret via `envFrom: secretRef: <fullname>-secrets`, so ESO patching the
|
|
# same Secret with `creationPolicy: Merge` injects `JWT_SECRET` into the
|
|
# pod env without forking the chart.
|
|
# - OAuth credentials for Meta/X/LinkedIn etc. are NOT pre-seeded — Postiz
|
|
# stores those in its own DB once the user adds providers via the UI.
