Your organization may require connecting to the database instance over SSL. To
|
|
supply Coder with the appropriate certificates, and have it connect over SSL,
|
|
follow the steps below:
|
|
|
|
## Client verification (server verifies the client)
|
|
|
|
1. Create the certificate as a secret in your Kubernetes cluster, if not already
|
|
present:
|
|
|
|
```shell
|
|
kubectl create secret tls postgres-certs -n coder --key="postgres.key" --cert="postgres.crt"
|
|
```
|
|
|
|
1. Define the secret volume and volumeMounts in the Helm chart:
|
|
|
|
```yaml
|
|
coder:
|
|
volumes:
|
|
- name: "pg-certs-mount"
|
|
secret:
|
|
secretName: "postgres-certs"
|
|
volumeMounts:
|
|
- name: "pg-certs-mount"
|
|
mountPath: "$HOME/.postgresql"
|
|
readOnly: true
|
|
```
|
|
|
|
1. Lastly, your PG connection URL will look like:
|
|
|
|
```shell
|
|
postgres://<user>:<password>@databasehost:<port>/<db-name>?sslmode=require&sslcert="$HOME/.postgresql/postgres.crt&sslkey=$HOME/.postgresql/postgres.key"
|
|
```
|
|
|
|
## Server verification (client verifies the server)
|
|
|
|
1. Download the CA certificate chain for your database instance, and create it
|
|
as a secret in your Kubernetes cluster, if not already present:
|
|
|
|
```shell
|
|
kubectl create secret tls postgres-certs -n coder --key="postgres-root.key" --cert="postgres-root.crt"
|
|
```
|
|
|
|
1. Define the secret volume and volumeMounts in the Helm chart:
|
|
|
|
```yaml
|
|
coder:
|
|
volumes:
|
|
- name: "pg-certs-mount"
|
|
secret:
|
|
secretName: "postgres-certs"
|
|
volumeMounts:
|
|
- name: "pg-certs-mount"
|
|
mountPath: "$HOME/.postgresql/postgres-root.crt"
|
|
readOnly: true
|
|
```
|
|
|
|
1. Lastly, your PG connection URL will look like:
|
|
|
|
```shell
|
|
postgres://<user>:<password>@databasehost:<port>/<db-name>?sslmode=verify-full&sslrootcert="/home/coder/.postgresql/postgres-root.crt"
|
|
```
|
|
|
|
More information on connecting to PostgreSQL databases using certificates can
|
|
be found in the [PostgreSQL documentation](https://www.postgresql.org/docs/current/libpq-ssl.html#LIBPQ-SSL-CLIENTCERT).
