When you create a cluster with cortex cluster up, an environment named aws or gcp is automatically created to point to your cluster and is configured to be the default environment. You can name the environment something else via the --configure-env flag, e.g. cortex cluster up --configure-env prod. You can also use the --configure-env flag with cortex cluster info and cortex cluster configure to create / update the specified environment.

You can list your environments with cortex env list, change the default environment with cortex env default, delete an environment with cortex env delete, and create/update an environment with cortex env configure.

Multiple clusters

cortex cluster up --config cluster1.yaml --configure-env cluster1  # configures the cluster1 env
cortex cluster up --config cluster2.yaml --configure-env cluster2  # configures the cluster2 env
​
cortex deploy --env cluster1
cortex logs my-api --env cluster1
cortex delete my-api --env cluster1
​
cortex deploy --env cluster2
cortex logs my-api --env cluster2
cortex delete my-api --env cluster2

Multiple clusters, if you omitted the --configure-env on cortex cluster up

cortex cluster info --config cluster1.yaml --configure-env cluster1  # configures the cluster1 env
cortex cluster info --config cluster2.yaml --configure-env cluster2  # configures the cluster2 env
​
cortex deploy --env cluster1
cortex logs my-api --env cluster1
cortex delete my-api --env cluster1
​
cortex deploy --env cluster2
cortex logs my-api --env cluster2
cortex delete my-api --env cluster2

Configure cortex CLI to connect to an existing cluster

If you are installing the cortex CLI on a new machine, you can configure it to access an existing Cortex cluster.

On the machine which already has the CLI configured, run:

cortex env list

Take note of the environment name and operator endpoint of the desired environment.

On your new machine, run:

cortex env configure

This will prompt for the necessary configuration. Note that the AWS credentials that you use here do not need any IAM permissions attached. If you will be running any cortex cluster commands specify the preferred AWS credentials using cli flags --aws-key AWS_ACCESS_KEY_ID --aws-secret AWS_SECRET_ACCESS_KEY.
