To connect to Gremlin services from our Kubernetes cluster, we will need to store our Gremlin credentials as a Kubernetes Secret. 

Let's perform the following steps to configure our Gremlin credentials:

1. Log in to the Gremlin service at https://app.gremlin.com/.
2. From the account menu, click on Company Settings:

3. Click on the Teams tab and select your team:

4. Click on the Configuration tab and download your certificates:

5. Copy the certificates.zip file to your host where kubectl has been configured.
6. Extract the files:

$ unzip certificate.zip

7. Rename the certificate files accordingly:

$ mv Me-client.pub_cert.pem gremlin.cert && mv Me-client.priv_key.pem gremlin.key

8. Create a Secret resource in your cluster:

$ kubectl create secret generic gremlin-team-cert --from-file=./gremlin.cert --from-file=./gremlin.key

With that, we have converted our credentials into secret resources in Kubernetes. This secret will be used later to connect Gremlin to our cluster.
