The following steps will quickly deploy a Rancher server on Outscale 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.

Prerequisites

Note Deploying to Outscale will incur charges.

  • Outscale Account: You will require an account on Outscale as this is where the server and cluster will run.
  • Outscale Access Key: Use these instructions to create an Outscale Access Key if you don’t have one.
  • Terraform: Used to provision the server and cluster in Outscale.

Getting Started

  1. Clone Rancher Quickstart to a folder using git clone https://github.com/rancher/quickstart.

  2. Go into the Outscale folder containing the terraform files by executing cd quickstart/rancher/outscale.

  3. Rename the terraform.tfvars.example file to terraform.tfvars.

  4. Edit terraform.tfvars and customize the following variables:

    • access_key_id - Outscale access key
    • secret_key_id - Outscale secret key
    • rancher_server_admin_password - Admin password for created Rancher server
  5. Optional: Modify optional variables within terraform.tfvars. See the Quickstart Readme and the Outscale Quickstart Readme for more information. Suggestions include:

    • region - Outscale region, choose the closest instead of the default (eu-west-2)
    • prefix - Prefix for all created resources
    • instance_type - Instance type, minimum required is tinav3.c2r4p3
  6. Run terraform init.

  7. To initiate the creation of the environment, run terraform apply --auto-approve. Then wait for output similar to the following:

    Apply complete! Resources: 21 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
    
  8. Paste the rancher_server_url from the output above into the browser. Log in when prompted (default username is admin, use the password set in rancher_server_admin_password).

  9. ssh to the Rancher Server using the id_rsa key generated in quickstart/rancher/outscale.

Result

Two Kubernetes clusters are deployed into your Outscale 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.

What’s Next?

Use Rancher to create a deployment. For more information, see Creating Deployments.

Destroying the Environment

  1. From the quickstart/rancher/outscale folder, execute terraform destroy --auto-approve.

  2. Wait for confirmation that all resources have been destroyed.
