Set up kubectl

Although it is not necessary to use kubectl to interact with Cortex clusters, advanced users can use kubectl to get more granular visibility into the cluster (since Cortex is built on top of Kubernetes).

Here's how to set up kubectl and connect it to your existing Cortex cluster:

Step 1

Install kubectl by following these instructions.

Step 2

Install eksctl by following these instructions.

Step 3

Make sure that your AWS credentials are available in your current shell environment. eksctl will search for credentials in the AWS_ACCESS_KEY_ID and AWS_SECRET_ACCESS_KEY environment variables, or your aws CLI's credentials file (which can be created with aws configure).

Step 4

Run the following command:

$ eksctl utils write-kubeconfig --cluster=<cluster_name> --region=<region>

Where <cluster_name> is the name of your cluster and <region> is the region of the cluster. These were specified when your cluster was created, either via command line prompts or your cluster configuration file (e.g. cluster.yaml). The default cluster name is cortex, and the default region is us-east-1.

Step 4

Test kubectl against the existing Cortex cluster by running a command like the following. Your output will be different.

$ kubectl get pods
‚Äč
NAME READY STATUS RESTARTS AGE
cloudwatch-agent-statsd-flwmv 1/1 Running 0 6m16s
fluentd-bv8xl 1/1 Running 0 6m20s
fluentd-vrwhw 1/1 Running 0 6m20s
operator-dc489b4f9-mmwkz 1/1 Running 0 6m14s

kubectl is now configured!
