## PostgreSQL
|
|
|
|
Zitadel requires PostgreSQL 14 or later. The chart supports multiple ways to connect to PostgreSQL depending on your security requirements.
|
|
|
|
### Connecting Without TLS (Not Recommended)
|
|
|
|
This method connects to PostgreSQL without encryption. Only use this for testing or when the database is on a private network with no risk of interception.
|
|
|
|
```yaml
|
|
zitadel:
|
|
configmapConfig:
|
|
Database:
|
|
Postgres:
|
|
Host: "postgres.database.svc.cluster.local"
|
|
Port: 5432
|
|
Database: "zitadel"
|
|
User:
|
|
Username: "zitadel"
|
|
Password: "your-password"
|
|
SSL:
|
|
Mode: "disable"
|
|
Admin:
|
|
Username: "postgres"
|
|
Password: "your-admin-password"
|
|
SSL:
|
|
Mode: "disable"
|
|
```
|
|
|
|
The `SSL.Mode: "disable"` setting turns off TLS entirely. Traffic between Zitadel and PostgreSQL is unencrypted.
|
|
|
|
### Connecting with Credentials and TLS
|
|
|
|
This method connects to PostgreSQL with TLS encryption but without certificate verification. Use this when you trust the network path but want encryption in transit.
|
|
|
|
```yaml
|
|
zitadel:
|
|
configSecretName: zitadel-db-credentials
|
|
configmapConfig:
|
|
Database:
|
|
Postgres:
|
|
Host: "postgres.database.svc.cluster.local"
|
|
Port: 5432
|
|
Database: "zitadel"
|
|
User:
|
|
Username: "zitadel"
|
|
SSL:
|
|
Mode: "require"
|
|
Admin:
|
|
Username: "postgres"
|
|
SSL:
|
|
Mode: "require"
|
|
```
|
|
|
|
Create a secret for the database passwords:
|
|
|
|
```bash
|
|
kubectl create secret generic zitadel-db-credentials \
|
|
--from-literal=config.yaml="
|
|
Database:
|
|
Postgres:
|
|
User:
|
|
Password: your-secure-app-password
|
|
Admin:
|
|
Password: your-secure-admin-password
|
|
"
|
|
```
|
|
|
|
The `SSL.Mode: "require"` setting enforces TLS but does not verify the server certificate. This protects against passive eavesdropping but not against man-in-the-middle attacks.
|
|
|
|
### Connecting with Certificates
|
|
|
|
This method connects to PostgreSQL with full TLS verification using certificates. Use this for production deployments where you need to verify the database server's identity.
|
|
|
|
```yaml
|
|
zitadel:
|
|
configSecretName: zitadel-db-credentials
|
|
dbSslCaCrt: "ca.crt"
|
|
dbSslCaCrtSecret: "postgres-ca-cert"
|
|
configmapConfig:
|
|
Database:
|
|
Postgres:
|
|
Host: "postgres.database.svc.cluster.local"
|
|
Port: 5432
|
|
Database: "zitadel"
|
|
User:
|
|
Username: "zitadel"
|
|
SSL:
|
|
Mode: "verify-full"
|
|
Admin:
|
|
Username: "postgres"
|
|
SSL:
|
|
Mode: "verify-full"
|
|
```
|
|
|
|
Create a secret containing the CA certificate:
|
|
|
|
```bash
|
|
kubectl create secret generic postgres-ca-cert \
|
|
--from-file=ca.crt=/path/to/your/ca-certificate.crt
|
|
```
|
|
|
|
Create a secret for the database passwords:
|
|
|
|
```bash
|
|
kubectl create secret generic zitadel-db-credentials \
|
|
--from-literal=config.yaml="
|
|
Database:
|
|
Postgres:
|
|
User:
|
|
Password: your-secure-app-password
|
|
Admin:
|
|
Password: your-secure-admin-password
|
|
"
|
|
```
|
|
|
|
The `SSL.Mode: "verify-full"` setting enforces TLS and verifies that the server certificate is signed by the CA and that the server hostname matches the certificate. This provides full protection against eavesdropping and man-in-the-middle attacks. The `dbSslCaCrtSecret` references the Kubernetes Secret containing the CA certificate, and `dbSslCaCrt` specifies the key within that secret.
