identity-stack
Chart · Stacks · standard · v0.0.13
Hardened, operator-free self-hosted SSO/identity stack: Keycloak (OIDC/SAML identity provider) + PostgreSQL (Keycloak's database) + oauth2-proxy (an auth proxy you place in front of any upstream app to authenticate users against Keycloak), wired together so you get single sign-on in front of your apps out of the box.
Version
The latest line lives at the base page; older lines have their own page so you can pin and verify exactly that version. Only the most recent releases are listed — an older chart pins an older image digest.
