# multi-cloud-kubernetes
|
|
This is example code for how I deploy a cross cloud Kubernetes cluster to my home openstack, ramnode openstack, and digital ocean.
|
|
|
|
# Run
|
|
### Set ENVS on test.env
|
|
1. DIGITALOCEAN_ACCESS_TOKEN - api token to interact with Digital Ocean. Used by `terraform-code/digitalocean.tf`
|
|
2. RAMNODE_USERNAME - ramnode openstack username. Used by `terraform-code/ramnode.tf`
|
|
3. RAMNODE_PASSWORD - ramnode openstack password. Used by `terraform-code/ramnode.tf`
|
|
4. HOME_USERNAME - home openstack username. Used by `terraform-code/home.tf`
|
|
5. HOME_PASSWORD - home openstack password. Used by `terraform-code/home.tf`
|
|
6. ZEROTIER_NETWORK - zerotier network id. Used by `terraform-code/user-data.sh`
|
|
7. CLOUDFLARE_API - cloudflare api token. Used by `ansible/roles/kubernetes/templates/cloudflare-updater.yaml` to be passed to the cloudflare updater pod.
|
|
8. LONGHORN_USERNAME - any username you want to use for basic auth http for longhorn. Used by `ansible/roles/longhorn/templates/longhorn-ingress.yaml`. Basic auth created by `bin/longhorn-basic-auth.sh`
|
|
9. LONGHORN_PASSWORD - any password you want to use for basic auth http for longhorn. Used by `ansible/roles/longhorn/templates/longhorn-ingress.yaml`. Basic auth created by `bin/longhorn-basic-auth.sh`
|
|
|
|
Then run `source test.env`
|
|
|
|
### NOTES
|
|
1. My personal domain (codywimer.com) is hard coded throughout this project. If replicating, you'll have to change this.
|
|
2. My home openstack cloud and ramnodes openstack envs are hard coded in `terraform-code/home.tf` and `terraform-code/ramnode.tf`
|
|
|
|
### Deploy
|
|
`make deploy`
|
|
|
|
This will take your ENV's, pass them to terraform and ansible (see `bin/deploy.sh`) and do the following:
|
|
1. Install terraform in this repo
|
|
2. Run terraform to deploy cloud resources. Instances will be pre-configured via `terraform-code/user-data.sh` and use a Debian 10 cloud image.
|
|
3. Terraform will ouput an ansible inventory to `hosts.cfg`
|
|
4. Ansible will be run to deploy Kubernetes via RKE. It will create the `rke` directory where you will find `rke/kube_config_rke-k8s.yaml` to run `kubectl` commands after Kubernetes is deployed.
|
|
|
|
### Deploy Notes
|
|
1. The `rke` directory contains your kube config file as stated above, a state file rke uses when configuring, `rke/rke-k8s.yaml` which is the rke cluster config, `rke/auth` which is the Kubernetes secret for http basic auth for Longhorn, the `rke/configs` directory which has default resources deployed into Kubernetes, and the `rke/lonhorn` directory which has the Longhorn configs.
|
|
2. The Terraform state file is located at `terraform-code/terraform.tfstate`
|
|
|
|
### Destroy
|
|
`make destroy` |
