### I want to use my own postgresql/redis with your chart.
### I want to use my own postgresql with your chart.
Just set `postgresql.enabled` or `redis.enabled` to `false`, as described below.
Just set `postgresql.enabled` to `false` in the override file, then put the parameters of your database
Then - put your instance params to "external" field
instance in the `external` field.
You may also need to configure `username`, `database` and `password` fields
to connect to your own database:
```yml
postgresql:
enabled: false
external:
host: postgresql.default.svc.cluster.local
port: 5432
auth:
username: cvat
database: cvat
secret:
password: cvat_postgresql
```
In example above corresponding secret will be created automatically, but if you want to use existing secret change `secret.create` to `false` and set `name` of existing secret:
```yml
postgresql:
enabled: false
external:
host: postgresql.default.svc.cluster.local
port: 5432
secret:
create: false
name: "my-postgresql-secret"
```
The secret must contain the `database`, `username` and `password`
keys to access to the database
like:
```yml
apiVersion: v1
kind: Secret
metadata:
name: "my-postgresql-secret"
namespace: default
type: generic
stringData:
database: cvat
username: cvat
password: secretpassword
```
### I want to use my own redis with your chart.
Just set `redis.enabled` to `false` in the override file, then put the parameters of your Redis
instance in the `external` field.
You may also need to configure `password` field to connect to your own Redis:
```yml
redis:
enabled: false
external:
host: redis.hostname.local
secret:
password: cvat_redis
```
In the above example the corresponding secret will be created automatically, but if you want to use an existing secret
change `secret.create` to `false` and set `name` of the existing secret:
```yml
redis:
enabled: false
external:
host: redis.hostname.local
secret:
create: false
name: "my-redis-secret"
```
The secret must contain the `redis-password` key like:
```yml
apiVersion: v1
kind: Secret
metadata:
name: "my-redis-secret"
namespace: default
type: generic
stringData:
redis-password: secretpassword
```
