gsctl - The Giant Swarm CLI (deprecated)

gsctl and the REST API are being phased out. We recommend to familiarize yourself with our Management API and the kubectl gs plugin as a future-proof replacement.

For customers still using the Giant Swarm REST API, gsctl is a cross-platform command line utility to manage clusters.

Usage

Call gsctl without any arguments to get an overview on commands. Some usage examples:

Log in using your Giant Swarm credentials

$ gsctl login demo@example.com -e <giant-swarm-api-endpoint>
Password for demo@example.com at <giant-swarm-api-endpoint>:
Successfully logged in!

Show your clusters

$ gsctl list clusters
ID     NAME                CREATED                 ORGANIZATION
9gxjo  Production Cluster  2016 Apr 30, 15:43 UTC  acme
xl8t1  Staging Cluster     2017 May 11, 09:30 UTC  acme

Create a cluster

$ gsctl create cluster --owner acme --name "Test Cluster" --num-workers 5
Requesting new cluster for organization 'acme'
New cluster with ID 'h8d0j' is launching.

Configure kubectl to access a cluster

$ gsctl create kubeconfig -c h8d0j
Creating new key pair…
New key pair created with ID 153a93201… and expiry of 720 hours
Certificate and key files written to:
/Users/demo/.config/gsctl/certs/h8d0j-ca.crt
/Users/demo/.config/gsctl/certs/h8d0j-153a932010-client.crt
/Users/demo/.config/gsctl/certs/h8d0j-153a932010-client.key
Switched to kubectl context 'giantswarm-xl8t1'

kubectl is set up. Check it using this command:

    kubectl cluster-info

Whenever you want to switch to using this context:

    kubectl config use-context giantswarm-xl8t1

Note: You can launch the context using Kubie by using --kubie switch

Cluster acccess via internal networks

The internal Kubernetes API endpoint allows you to talk to Kubernetes via the internal load balancer. That can be useful for peered networks.

In case you want to use the internal Kubernetes API, pass --internal-api=true to gsctl when creating a kubectl config entry:

gsctl create kubeconfig -c h8d0j --internal-api=true

This will render a kubeconfig with the internal Kubernetes API host name internal-api, resolving to the internal load balancer.

Note: The internal API endpoint is available only on AWS installations.
