This pull request significantly expands and restructures the Kubernetes
deployment documentation for Zitadel. It introduces detailed,
task-focused guides for installation, configuration, ingress, and
database setup, replacing the previous minimal documentation. The new
docs provide comprehensive instructions and best practices for deploying
Zitadel on Kubernetes using Helm, including security, scaling, and high
availability considerations.
The most important changes are:
**Documentation Restructuring and Overview**
- Added a new `index.mdx` providing an overview of the Zitadel Helm
chart, architecture, prerequisites, and quick links to relevant
resources and next steps.
- Removed the old minimal Kubernetes deployment page and replaced it
with a structured, multi-page documentation set.
**Installation and Setup**
- Added an `installation.mdx` guide with step-by-step instructions for
preparing prerequisites, creating Kubernetes secrets, configuring
`values.yaml`, installing the Helm chart, and verifying the deployment.
**Configuration and Best Practices**
- Added a `configuration.mdx` guide covering Helm chart configuration
options, including replica count, container images, security contexts,
external domain setup, secrets management, scaling, autoscaling, pod
disruption budgets, and anti-affinity rules.
**Ingress and Database Configuration**
- Added an `ingress.mdx` guide detailing how to configure Kubernetes
ingress resources for Zitadel and Login containers, including TLS
termination and certificate management.
- Added a `database.mdx` guide explaining how to connect Zitadel to
PostgreSQL with various TLS/security options and how to manage database
credentials and certificates using Kubernetes secrets.
## Todos for release
- [x] Configure Env in docs project on vercel
- [x] Configure Root Path in the docs project on vercel
- [ ] Remove old CSP https://github.com/zitadel/website/pull/1592
## What we did
This pull request migrates the project documentation from the old
`docs/` directory to the new `apps/docs/` directory, introduces a new
documentation system built with Next.js and Fumadocs, and updates all
relevant references, configuration files, and documentation to reflect
this change. It also adds new configuration and ignore files for the new
documentation app, updates CI and linting to exclude the new docs from
certain checks, and revises the contributing guidelines accordingly.
**Documentation System Migration and New Docs App**
* Migrated all documentation from `docs/` to `apps/docs/`, and updated
all references in `README.md`, `CONTRIBUTING.md`, and other files to
point to the new location.

and a comprehensive `README.md` with development and contribution
instructions.

**Configuration and Tooling Updates**
* Updated `.github/workflows/codeql.yml`, `.golangci.yaml`, and
`.github/dependabot.yml` to properly handle the new docs app: excluded
`apps/docs` from certain checks, added npm dependency updates for the
docs app, and excluded generated content.

* Updated `.devcontainer/devcontainer.json` to use the latest Go 1.25.3
version for consistency.
**Licensing and Miscellaneous**
* Added `apps/docs/` to the list of licensed directories in
`LICENSING.md`.
These changes ensure the documentation is now maintained in a modern,
scalable system and all project tooling is updated to support the new
structure.
