Summary

• document optional ingressClassName rendering and networkPolicy.extraEgress behavior for Memos
• expose Memos NetworkPolicy controls and empty ingress class option in the playground registry
• register Memos in the playground site-sync map

Validation

• make site-sync-check CHART=memos
• npm run lint
• npm run format:check
• npm run build

Chart PR: helmforgedev/charts#671
Issue: helmforgedev/charts#633

Summary by CodeRabbit

• New Features

  • Updated the olivetin chart playground with an expanded “Ingress Class” selector (including an empty choice).
  • Added a new NetworkPolicy collapsible section, gated by networkPolicy.enabled, including “Database Egress Port” (default 5432).
  • Included memos in the set of charts eligible for site-synced playground behavior.

8140-8146: 🗄️ Data Integrity & Integration | 🔵 Trivial | ⚡ Quick win

Memos ingress class options lack the empty option now documented in memos.mdx.

The updated memos.mdx documents setting ingress.ingressClassName: "" to omit spec.ingressClassName, mirroring the pattern already used for apache and now olivetin (options: ['', ...]). The memos entry here still only offers ['traefik', 'nginx'], so playground users can't exercise the documented behavior.

♻️ Proposed fix

         {
           label: 'Ingress Class',
           key: 'ingress.ingressClassName',
           type: 'select',
           default: 'traefik',
-          options: ['traefik', 'nginx'],
+          options: ['', 'traefik', 'nginx'],
           description: 'Ingress controller class',
         },
