Using an external Atlas Mongo DB
- Rene Beckert
The deployment can be configured to use an external Mongo DB instance rather than deploying one in the cluster. At the moment this was tested with Atlas Mongo DB.
Add or change the following properties in your values file of Smartfacts to use an external Mongo DB:
property | value to be set | remark | Default value in chart |
|---|---|---|---|
| The name of the secret containing the mongodb connection string. | Opaqe secret with key The connection string contains the username and password of the mongodb user to use. |
|
| false | Deactivates the deployment of mongodb in the cluster. | true |
| true | Mongo Atlas limits the length of data base names to 38 bytes (instead of 63). Therefore this flag must be true if Mongo Atlas DB is used. | false |
| true | Mongo Atlas limits the length of collections. Therefor this flag must be set to true Mongo Atlas DB is used. | false |
To create the secret for the mongdb connection string, you can use this command:
kubectl create secret generic <mongodbConnectionSecretName> --from-literal=connection-string=<mongodb connection string> -n smartfactsReplace
<mongodbConnectionSecretName>with the name of the secret you have set in the values file, or<release name>-mongodb-connection-secretif you did not set the propertymongodbConnectionSecretName.Replace
<mongodb connection string>with the Mongodb connection string
