# Prerequisites ### Create Credentials for MongoDB Exporter If you want to use a non-admin user for the exporter, you will have to create a user and grant the roles to be able to scrape statistics. In the mongo shell: ```sql use admin db.auth("", "") db.createUser( { user: "", pwd: "", roles: [ { role: "clusterMonitor", db: "admin" }, { role: "read", db: "admin" }, { role: "read", db: "local" } ] } ) ``` ### Create Kubernetes Secret for Connection and Authentication To configure authentication, do the following: 1. Create a text file with the connection string (mongodb-uri) for your MongoDB by using these examples: ``` # Basic authentication mongodb://:@: # TLS mongodb://:@:/admin?tls=true&tlsCertificateKeyFile=/etc/mongodb/mongodb-exporter-key.pem&tlsAllowInvalidCertificates=true&tlsCAFile=/etc/mongodb/mongodb-exporter-ca.pem # SSL mongodb://:@:/admin?ssl=true&sslclientcertificatekeyfile=/etc/mongodb/mongodb-exporter-key.pem&sslinsecure=true&sslcertificateauthorityfile=/etc/mongodb/mongodb-exporter-ca.pem ``` 2. Create the secret for the connection string: ``` kubectl create secret -n Your-Exporter-Namespace generic Your-Mongodb-Uri-Secret-Name \ --from-file=mongodb-uri= ``` 3. In case of TLS or SSL authentication, create the secret with the private key and the certificate authority (CA). If you do not have a CA file, you can use an empty file instead: ``` kubectl create secret -n Your-Exporter-Namespace generic mongodb-exporter-auth \ --from-file=mongodb-key= \ --from-file=mongodb-ca= ``` # Installation You can use our helm-charts in order to install the exporter in your cluster. ```sh helm install --repo https://sysdiglabs.github.io/integrations-charts mongodb-exporter mongodb-exporter ```
