+# Installing a managed cluster
+
+*"The easiest way to install Kubernetes is to get someone
+else to do it for you."
+<br/>
+([Jérôme Petazzoni](https://twitter.com/jpetazzo))*
+
+- Let's see a few options to install managed clusters!
+
+- All the options mentioned here require an account
+with a cloud provider
+
+- ... And a credit card
+
+---
+
+## EKS (the hard way)
+
+- [Read the doc](https://docs.aws.amazon.com/eks/latest/userguide/getting-started.html)
+
+- Create service roles, VPCs, and a bunch of other oddities
+
+- Try to figure out why it doesn't work
+
+- Start over, following an [official AWS blog post](https://aws.amazon.com/blogs/aws/amazon-eks-now-generally-available/)
+
+- Try to find the missing Cloud Formation template
+
+--
+
+.footnote[(╯°□°)╯︵ ┻━┻]
+
+---
+
+## EKS (the easy way)
+
+- Install `eksctl`
+
+- Set the usual environment variables
+
+  ([AWS_DEFAULT_REGION](https://docs.aws.amazon.com/general/latest/gr/rande.html#eks_region), AWS_ACCESS_KEY, AWS_SECRET_ACCESS_KEY)
+
+- Create the cluster:
+  ```bash
+  eksctl create cluster
+  ```
+
+- Wait 15-20 minutes (yes, it's sloooooooooooooooooow)
+
+- Add cluster add-ons
+
+  (by default, it doesn't come with metrics-server, logging, etc.)
+
+---
+
+## EKS (cleanup)
+
+- Delete the cluster:
+  ```bash
+  eksctl delete cluster <clustername>
+  ```
+
+- If you need to find the name of the cluster:
+  ```bash
+  eksctl get clusters
+  ```
+
+---
+
+## GKE (initial setup)
+
+- Install `gcloud`
+
+- Login:
+  ```bash
+  gcloud auth init
+  ```
+
+- Create a "project":
+  ```bash
+  gcloud projects create my-gke-project
+  gcloud config set project my-gke-project
+  ```
+
+- Pick a [region](https://cloud.google.com/compute/docs/regions-zones/)
+
+  (example: `europe-west1`, `us-west1`, ...)
+
+---
+
+## GKE (create cluster)
+
+- Create the cluster:
+  ```bash
+  gcloud container clusters create my-gke-cluster --region us-west1 --num-nodes=2
+  ```
+
+  (without `--num-nodes` you might exhaust your IP address quota!)
+
+- The first time you try to create a cluster in a given project, you get an error
+
+  - you need to enable the Kubernetes Engine API
+  - the error message gives you a link
+  - follow the link and enable the API (and billing)
+    <br/>(it's just a couple of clicks and it's instantaneous)
+
+- Wait a couple of minutes (yes, it's faaaaaaaaast)
+
+- The cluster comes with many add-ons
+
+---
+
+## GKE (cleanup)
+
+- List clusters (if you forgot its name):
+  ```bash
+  gcloud container clusters list
+  ```
+
+- Delete the cluster:
+  ```bash
+  gcloud container clusters delete my-gke-cluster --region us-west1
+  ```
+
+- Delete the project (optional):
+  ```bash
+  gcloud projects delete my-gke-project
+  ```
+
+---
+
+## AKS (initial setup)
+
+- Install the Azure CLI
+
+- Login:
+  ```bash
+  az login
+  ```
+
+- Select a [region](https://azure.microsoft.com/en-us/global-infrastructure/services/?products=kubernetes-service&regions=all
+)
+
+- Create a "resource group":
+  ```bash
+  az group create --name my-aks-group --location westeurope
+  ```
+
+---
+
+## AKS (create cluster)
+
+- Create the cluster:
+  ```bash
+  az aks create --resource-group my-aks-group --name my-aks-cluster
+  ```
+
+- Wait 15 minutes (sometimes longer)
+
+- Add credentials to `kubeconfig`:
+  ```bash
+  az aks get-credentials --resource-group my-aks-group --name my-aks-cluster
+  ```
+
+- The cluster has a lot of goodies pre-installed
+
+---
+
+## AKS (cleanup)
+
+- Delete the cluster:
+  ```bash
+  az aks delete --resource-group my-aks-group --name my-aks-cluster
+  ```
+
+- Delete the resource group:
+  ```bash
+  az group delete --resource-group aks-test
+  ```
+
+- Note: delete actions can take a long time too!
+
+  (10 minutes is typical)
+
+---
+
+## Digital Ocean (initial setup)
+
+- Install `doctl`
+
+- Generate API token (in web console)
+
+- Set up the CLI authentication:
+  ```bash
+  doctl auth init
+  ```
+  (It will ask you for the API token)
+
+- Check the list of regions and pick one:
+  ```bash
+  doctl compute region list
+  ```
+  (If you don't specify the region later, it will use `nyc1`)
+
+---
+
+## Digital Ocean (create cluster)
+
+- Create the cluster:
+  ```bash
+  doctl kubernetes cluster create my-do-cluster [--region xxx1]
+  ```
+
+- Wait 5 minutes
+
+- Update `kubeconfig`:
+  ```bash
+  kubectl config use-context do-xxx1-my-do-cluster
+  ```
+
+- The cluster comes with some goodies (like Cilium) but no metrics server
+
+---
+
+## Digital Ocean (cleanup)
+
+- List clusters (if you forgot its name):
+  ```bash
+  doctl kubernetes cluster list
+  ```
+
+- Delete the cluster:
+  ```bash
+  doctl kubernetes cluster delete my-do-cluster
+  ```
