Using a simple managed Kubernetes cluster on Digitalocean you can bootstrap it with Argo CD and an inital app-of-apps seed application. then all your applications from a git repo are automagically pulled onto your cluster. After this initial cluster bootstrapping argocd handle the deployment of all your kubernetes resources
The following may be installed with brew. Run brew bundle
Required:
Minikube Terraform Kubernetes Helm
Optional:
Start minikube
minikube start
Set up Terraform environment variables
Using the workspace named dev here makes sure the terraform runs against a local minikube cluster
export TF_WORKSPACE=dev
Force Terraform to not use remote execution. We only care about terraform cloud state management
export TF_FORCE_LOCAL_BACKEND=1
The backend here is remote using terraform cloud. sign up for a free account, create an organization, skip creating a workspace and create a user API token.
export TF_CLI_ARGS_init="-backend-config='token=<TF CLOUD TOKEN>' -backend-config='organization=<TF CLOUD ORG NAME>'"
Create a digitalocean access token or make one up if just local testing
export DIGITALOCEAN_ACCESS_TOKEN=<DO API TOKEN>
Now create a new terraform workspace
terraform workspace new $TF_WORKSPACE
Run the standard terraform commands
terraform init
terraform plan
terraform apply
Check your local minikube cluster with kubectl or a tool like k9s and see the various pods created. you can even portforward argo-cd admin UI and sync to get all the example apps installed. You can get the argocd admin UI password here
