The following steps will quickly deploy a Rancher server on DigitalOcean in a single-node K3s Kubernetes cluster, with a single-node downstream Kubernetes cluster attached.
|
|
|
|
:::caution
|
|
|
|
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](../../../pages-for-subheaders/installation-and-upgrade.md).

## Prerequisites
|
|
|
|
:::caution
|
|
|
|
Deploying to DigitalOcean will incur charges.
|
|
|
|
:::
|
|
|
|
- [DigitalOcean Account](https://www.digitalocean.com): You will require an account on DigitalOcean as this is where the server and cluster will run.
|
|
- [DigitalOcean Access Key](https://www.digitalocean.com/community/tutorials/how-to-create-a-digitalocean-space-and-api-key): Use this link to create a DigitalOcean Access Key if you don't have one.
|
|
- [Terraform](https://www.terraform.io/downloads.html): Used to provision the server and cluster to DigitalOcean.
|
|
|
|
|
|
## Getting Started
|
|
|
|
1. Clone [Rancher Quickstart](https://github.com/rancher/quickstart) to a folder using `git clone https://github.com/rancher/quickstart`.
|
|
|
|
2. Go into the DigitalOcean folder containing the Terraform files by executing `cd quickstart/rancher/do`.
|
|
|
|
3. Rename the `terraform.tfvars.example` file to `terraform.tfvars`.
|
|
|
|
4. Edit `terraform.tfvars` and customize the following variables:
|
|
- `do_token` - DigitalOcean access key
|
|
- `rancher_server_admin_password` - Admin password for created Rancher server (minimum 12 characters)
|
|
|
|
5. **Optional:** Modify optional variables within `terraform.tfvars`.
|
|
See the [Quickstart Readme](https://github.com/rancher/quickstart) and the [DO Quickstart Readme](https://github.com/rancher/quickstart/tree/master/rancher/do) for more information. Suggestions include:
|
|
- `do_region` - DigitalOcean region, choose the closest instead of the default (`nyc1`)
|
|
- `prefix` - Prefix for all created resources
|
|
- `droplet_size` - Droplet size used, minimum is `s-2vcpu-4gb` but `s-4vcpu-8gb` could be used if within budget
|
|
|
|
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: 15 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/do`.
|
|
|
|
#### Result
|
|
|
|
Two Kubernetes clusters are deployed into your DigitalOcean 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](../../../pages-for-subheaders/deploy-rancher-workloads.md).
|
|
|
|
## Destroying the Environment
|
|
|
|
1. From the `quickstart/rancher/do` folder, execute `terraform destroy --auto-approve`.
|
|
|
|
2. Wait for confirmation that all resources have been destroyed.
