The following steps will quickly deploy a Rancher server on GCP in a single-node K3s Kubernetes cluster, with a single-node downstream Kubernetes cluster attached.
Note: The intent of these guides is to quickly launch a sandbox that you can use to evaluate Rancher. These guides are not intended for production environments. For comprehensive setup instructions, see Installation.
Note Deploying to Google GCP will incur charges.
- Google GCP Account: A Google GCP Account is required to create resources for deploying Rancher and Kubernetes.
- Google GCP Project: Use this link to follow a tutorial to create a GCP Project if you don’t have one yet.
- Google GCP Service Account: Use this link and follow instructions to create a GCP service account and token file.
- Terraform: Used to provision the server and cluster in Google GCP.
Clone Rancher Quickstart to a folder using
git clone https://github.com/rancher/quickstart.
Go into the GCP folder containing the terraform files by executing
terraform.tfvarsand customize the following variables:
gcp_account_json- GCP service account file path and file name
rancher_server_admin_password- Admin password for created Rancher server
gcp_region- Google GCP region, choose the closest instead of the default (
gcp_zone- Google GCP zone, choose the closest instead of the default (
prefix- Prefix for all created resources
machine_type- Compute instance size used, minimum is
n1-standard-4could be used if within budget
To initiate the creation of the environment, run
terraform apply --auto-approve. Then wait for output similar to the following:
Apply complete! Resources: 16 added, 0 changed, 0 destroyed. Outputs: rancher_node_ip = xx.xx.xx.xx rancher_server_url = https://rancher.xx.xx.xx.xx.sslip.io workload_node_ip = yy.yy.yy.yy
rancher_server_urlfrom the output above into the browser. Log in when prompted (default username is
admin, use the password set in
ssh to the Rancher Server using the
id_rsakey generated in
Two Kubernetes clusters are deployed into your GCP account, one running Rancher Server and the other ready for experimentation deployments. Please note that while this setup is a great way to explore Rancher functionality, a production setup should follow our high availability setup guidelines. SSH keys for the VMs are auto-generated and stored in the module directory.
Use Rancher to create a deployment. For more information, see Creating Deployments.
Destroying the Environment
terraform destroy --auto-approve.
Wait for confirmation that all resources have been destroyed.
