-10. Clean up leftovers.
-
-Some providers don't clean up properly the resources created by the CCM.
-For instance, when you create a Kubernetes `Service` of type
-`LoadBalancer`, it generally provisions a cloud load balancer.
-On Linode (and possibly other providers, too!) these cloud load balancers
-aren't deleted when the cluster gets deleted, and they keep incurring
-charges. You should check for those, to make sure that you don't
-get charged for resources that you don't use anymore. As I write this
-paragraph, there is:
-
-- `linode-delete-ccm-loadbalancers.sh` to delete the Linode
-  nodebalancers; but be careful: it deletes **all** the nodebalancers
-  whose name starts with `ccm-`, which means that if you still have
-  Kubernetes clusters, their load balancers will be deleted as well!
-
-- `linode-delete-pvc-volumes.sh` to delete Linode persistent disks
-  that have been created to satisfy Persistent Volume Claims
-  (these need to be removed manually because the default Storage Class
-  on Linode has a RETAIN policy). Again, be careful, this will wipe
-  out any volume whose label starts with `pvc`. (I don't know if it
-  will remove volumes that are still attached.)
-
-Eventually, I hope to add more scripts for other providers, and make
-them more selective and more robust, but for now, that's better than
-nothing.

 # Exercise — Ingress
 
-- We want to expose a couple of web apps through an ingress controller
+- We want to expose a web app through an ingress controller
 
 - This will require:
 
-  - the web apps (e.g. two instances of `jpetazzo/color`)
+  - the web app itself (dockercoins, NGINX, whatever we want)
 
   - an ingress controller
 
+  - a domain name (`use \*.nip.io` or `\*.localdev.me`)
+
   - an ingress resource
 
 ---
 
-## Different scenarios
+## Goal
 
-We will use a different deployment mechanism depending on the cluster that we have:
+- We want to be able to access the web app using a URL like:
 
-- Managed cluster with working `LoadBalancer` Services
+  http://webapp.localdev.me
 
-- Local development cluster
+  *or*
 
-- Cluster without `LoadBalancer` Services (e.g. deployed with `kubeadm`)
+  http://webapp.A.B.C.D.nip.io
 
----
-
-## The apps
-
-- The web apps will be deployed similarly, regardless of the scenario
-
-- Let's start by deploying two web apps, e.g.:
-
-  a Deployment called `blue` and another called `green`, using image `jpetazzo/color`
-
-- Expose them with two `ClusterIP` Services
-
----
-
-## Scenario "classic cloud Kubernetes"
-
-*Difficulty: easy*
-
-For this scenario, we need a cluster with working `LoadBalancer` Services.
-
-(For instance, a managed Kubernetes cluster from a cloud provider.)
-
-We suggest to use "Ingress NGINX" with its default settings.
-
-It can be installed with `kubectl apply` or with `helm`.
-
-Both methods are described in [the documentation][ingress-nginx-deploy].
-
-We want our apps to be available on e.g. http://X.X.X.X/blue and http://X.X.X.X/green
-<br/>
-(where X.X.X.X is the IP address of the `LoadBalancer` allocated by Ingress NGINX).
-
-[ingress-nginx-deploy]: https://kubernetes.github.io/ingress-nginx/deploy/
-
----
-
-## Scenario "local development cluster"
-
-*Difficulty: easy-hard (depends on the type of cluster!)*
-
-For this scenario, we want to use a local cluster like KinD, minikube, etc.
-
-We suggest to use "Ingress NGINX" again, like for the previous scenario.
-
-Furthermore, we want to use `localdev.me`.
-
-We want our apps to be available on e.g. `blue.localdev.me` and `green.localdev.me`.
-
-The difficulty is to ensure that `localhost:80` will map to the ingress controller.
-
-(See next slide for hints!)
+  (where A.B.C.D is the IP address of one of our nodes)
 
 ---
 
 ## Hints
 
-- With clusters like Docker Desktop, the first `LoadBalancer` service uses `localhost`
+- For the ingress controller, we can use:
 
-  (if the ingress controller is the first `LoadBalancer` service, we're all set!)
+  - [ingress-nginx](https://github.com/kubernetes/ingress-nginx/blob/main/docs/deploy/index.md)
 
-- With clusters like K3D and KinD, it is possible to define extra port mappings
+  - the [Traefik Helm chart](https://doc.traefik.io/traefik/getting-started/install-traefik/#use-the-helm-chart)
 
-  (and map e.g. `localhost:80` to port 30080 on the node; then use that as a `NodePort`)
+  - the container.training [Traefik DaemonSet](https://raw.githubusercontent.com/jpetazzo/container.training/main/k8s/traefik-v2.yaml)
 
----
+- If our cluster supports LoadBalancer Services: easy
 
-## Scenario "on premises cluster", take 1
+  (nothing special to do)
 
-*Difficulty: easy*
+- For local clusters, things can be more difficult; two options:
 
-For this scenario, we need a cluster with nodes that are publicly accessible.
+  - map localhost:80 to e.g. a NodePort service, and use `\*.localdev.me`
 
-We want to deploy the ingress controller so that it listens on port 80 on all nodes.
-
-This can be done e.g. with the manifests in @@LINK[k8s/traefik.yaml].
-
-We want our apps to be available on e.g. http://X.X.X.X/blue and http://X.X.X.X/green
-<br/>
-(where X.X.X.X is the IP address of any of our nodes).
-
----
-
-## Scenario "on premises cluster", take 2
-
-*Difficulty: medium*
-
-We want to deploy the ingress controller so that it listens on port 80 on all nodes.
-
-But this time, we want to use a Helm chart to install the ingress controller.
-
-We can use either the Ingress NGINX Helm chart, or the Traefik Helm chart.
-
-Test with an untainted node first.
-
-Feel free to make it work on tainted nodes (e.g. control plane nodes) later.
-
----
-
-## Scenario "on premises cluster", take 3
-
-*Difficulty: hard*
-
-This is similar to the previous scenario, but with two significant changes:
-
-1. We only want to run the ingress controller on nodes that have the role `ingress`.
-
-2. We don't want to use `hostNetwork`, but a list of `externalIPs` instead.
+  - use hostNetwork, or ExternalIP, and use `\*.nip.io`

-## Exercise — Network Policies
-
-- Implement a system with 3 levels of security

-# Exercise — Network Policies
-
-We want to to implement a generic network security mechanism.
-
-Instead of creating one policy per service, we want to
-create a fixed number of policies, and use a single label
-to indicate the security level of our pods.
-
-Then, when adding a new service to the stack, instead
-of writing a new network policy for that service, we
-only need to add the right label to the pods of that service.
-
----
-
-## Specifications
-
-We will use the label `security` to classify our pods.
-
-- If `security=private`:
-
-  *the pod shouldn't accept any traffic*
-
-- If `security=public`:
-
-  *the pod should accept all traffic*
-
-- If `security=namespace`:
-
-  *the pod should only accept connections coming from the same namespace*
-
-If `security` isn't set, assume it's `private`.
-
----
-
-## Test setup
-
-- Deploy a copy of the DockerCoins app in a new namespace
-
-- Modify the pod templates so that:
-
-  - `webui` has `security=public`
-
-  - `worker` has `security=private`
-
-  - `hasher`, `redis`, `rng` have `security=namespace`
-
----
-
-## Implement and test policies
-
-- Write the network policies
-
-  (feel free to draw inspiration from the ones we've seen so far)
-
-- Check that:
-
-  - you can connect to the `webui` from outside the cluster
-
-  - the application works correctly (shows 3-4 hashes/second)
-
-  - you cannot connect to the `hasher`, `redis`, `rng` services
-
-  - you cannot connect or even ping the `worker` pods

-
-- Give each user read-only access to the other's namespace
-
-- Let `alice` view the nodes of the cluster as well
-
----
-
-## Initial setup
-
-- Create two namespaces named `alice` and `bob`
-
-- Check that if we impersonate Alice, we can't access her namespace yet:
-  ```bash
-  kubectl --as alice get pods --namespace alice
-  ```

-
-- Grant Alice full access to her own namespace
-
-  (you can use a pre-existing Cluster Role)

-  kubectl --as alice create deployment hello --image nginx --namespace alice

-  kubectl --as bob create deployment hello --image nginx --namespace alice

-## Read-only access
-
-- Now, give Alice read-only access to Bob's namespace
-
-- Check that Alice can view Bob's stuff:
-  ```bash
-  kubectl --as alice get pods --namespace bob
-  ```
-
-- But that she can't touch this:
-  ```bash
-  kubectl --as alice delete pods --namespace bob --all
-  ```
-
-- Likewise, give Bob read-only access to Alice's namespace
-
----
-
-## Nodes
-
-- Give Alice read-only access to the cluster nodes
-
-  (this will require creating a custom Cluster Role)
-
-- Check that Alice can view the nodes:
-  ```bash
-  kubectl --as alice get nodes

-- But that Bob cannot:
-  ```bash
-  kubectl --as bob get nodes
-  ```
-
-- And that Alice can't update nodes:
-  ```bash
-  kubectl --as alice label nodes --all hello=world
