Lukas Huppertz 9d613dc19d Improve helm chart // Fix linting issues & introduce Redis externalSecret for redis password // Add additional ENVs // Improve migrations (#18157)
This pull request enhances the Helm chart for the Twenty application by
improving how environment variables and Redis credentials are handled
for both server and worker deployments. The main changes include support
for injecting additional environment variables, improved Redis password
management (including external secrets), and a more robust database
migration workflow.

**Environment Variable Injection:**
- Added support for specifying additional environment variables for both
the server and worker deployments via the `additionalEnv` field in
`values.yaml`. These variables are automatically injected into the
respective pods.

**Redis Credential Management:**
- Introduced support for using external secrets for Redis passwords by
adding `secretName` and `passwordKey` fields under `redis.external` in
`values.yaml`, and logic to inject `REDIS_PASSWORD` from a Kubernetes
secret if configured.

- Updated the logic for constructing the `REDIS_URL` to include
authentication information if a password is set or an external secret is
used.

**Database Migration Workflow:**
- Improved the startup command for the server deployment to optionally
skip database migrations (using `DISABLE_DB_MIGRATIONS`), check for an
existing schema before running migrations, and ensure setup scripts are
only run on empty databases.

These changes make the chart more flexible and secure, especially for
production deployments requiring externalized secrets and custom
environment configurations.

Why Twenty

We built Twenty for three reasons:

CRMs are too expensive, and users are trapped. Companies use locked-in customer data to hike prices. It shouldn't be that way.

A fresh start is required to build a better experience. We can learn from past mistakes and craft a cohesive experience inspired by new UX patterns from tools like Notion, Airtable or Linear.

We believe in open-source and community. Hundreds of developers are already building Twenty together. Once we have plugin capabilities, a whole ecosystem will grow around it.
