+## Introducing JSON syntax
 
-## Why `sh -c`?
+Most Dockerfile arguments can be passed in two forms:
 
-* On UNIX, to start a new program, we need two system calls:
-
-  - `fork()`, to create a new child process;
-
-  - `execve()`, to replace the new child process with the program to run.
-
-* Conceptually, `execve()` works like this:
-
-  `execve(program, [list, of, arguments])`
-
-* When we run a command, e.g. `ls -l /tmp`, something needs to parse the command.
-
-  (i.e. split the program and its arguments into a list.)
-
-* The shell is usually doing that.
-
-  (It also takes care of expanding environment variables and special things like `~`.)
-
----
-
-class: extra-details
-
-## Why `sh -c`?
-
-* When we do `RUN ls -l /tmp`, the Docker builder needs to parse the command.
-
-* Instead of implementing its own parser, it outsources the job to the shell.
-
-* That's why we see `sh -c ls -l /tmp` in that case.
-
-* But we can also do the parsing jobs ourselves.
-
-* This means passing `RUN` a list of arguments.
-
-* This is called the *exec syntax*.
-
----
-
-## Shell syntax vs exec syntax
-
-Dockerfile commands that execute something can have two forms:
-
-* plain string, or *shell syntax*:
+* plain string:
   <br/>`RUN apt-get install figlet`
 
-* JSON list, or *exec syntax*:
+* JSON list:
   <br/>`RUN ["apt-get", "install", "figlet"]`
 
 We are going to change our Dockerfile to see how it affects the resulting image.

-## When to use exec syntax and shell syntax
+## When to use JSON syntax and string syntax
 
-* shell syntax:
+* String syntax:
 
   * is easier to write
   * interpolates environment variables and other shell expressions
   * creates an extra process (`/bin/sh -c ...`) to parse the string
   * requires `/bin/sh` to exist in the container
 
-* exec syntax:
+* JSON syntax:
 
   * is harder to write (and read!)
   * passes all arguments without extra processing
   * doesn't create an extra process
   * doesn't require `/bin/sh` to exist in the container
-
----
-
-## Pro-tip: the `exec` shell built-in
-
-POSIX shells have a built-in command named `exec`.
-
-`exec` should be followed by a program and its arguments.
-
-From a user perspective:
-
-- it looks like the shell exits right away after the command execution,
-
-- in fact, the shell exits just *before* command execution;
-
-- or rather, the shell gets *replaced* by the command.
-
----
-
-## Example using `exec`
-
-```dockerfile
-CMD exec figlet -f script hello
-```
-
-In this example, `sh -c` will still be used, but
-`figlet` will be PID 1 in the container.
-
-The shell gets replaced by `figlet` when `figlet` starts execution.
-
-This allows to run processes as PID 1 without using JSON.

-
-  - talk about tokens, certificates, service accounts, RBAC ...
-
-- But first: why do we need all this?

----
-
-## The need for fine-grained security
-
-- The Kubernetes API should only be available for identified users
-
-  - we don't want "guest access" (except in very rare scenarios)
-
-  - we don't want strangers to use our compute resources, delete our apps ...
-
-  - our keys and passwords should not be exposed to the public
-
-- Users will often have different access rights
-
-  - cluster admin (similar to UNIX "root") can do everything
-
-  - developer might access specific resources, or a specific namespace
-
-  - supervision might have read only access to *most* resources

-## Example: custom HTTP load balancer
-
-- Let's imagine that we have a custom HTTP load balancer for multiple apps
-
-- Each app has its own *Deployment* resource
-
-- By default, the apps are "sleeping" and scaled to zero
-
-- When a request comes in, the corresponding app gets woken up
-
-- After some inactivity, the app is scaled down again
-
-- This HTTP load balancer needs API access (to scale up/down)

-- What if *a wild vulnerability appears*?

-## Consequences of vulnerability
-
-- If the HTTP load balancer has the same API access as we do:
-
-  *full cluster compromise (easy data leak, cryptojacking...)*
-
-- If the HTTP load balancer has `update` permissions on the Deployments:
-
-  *defacement (easy), MITM / impersonation (medium to hard)*
-
-- If the HTTP load balancer only has permission to `scale` the Deployments:

-- API server must be more recent than its clients (kubelet and control plane)

-- All components support a difference of one¹ MINOR version

-- This allows live upgrades (since we can mix e.g. 1.15 and 1.16)

+## Disclaimers
+
+- There are many methods to interconnect clusters
+
+- Depending on your network implementation, you will use different methods
+
+- The method shown here only works for nodes with direct layer 2 connection
+
+- We will often need to use tunnels or other network techniques
+
+---
+
+## The plan

+- Someone will start the *route reflector*
+
+  (typically, that will be the person presenting these slides!)
+
+- We will update our kube-router configuration
+
+- We will add a *peering* with the route reflector

+
+- There is a Compose file in the `compose/frr-route-reflector` directory
+
+- Before continuing, make sure that you have the IP address of the route reflector
+
+---
+
+## Configuring kube-router
+
+- This can be done in two ways:
+
+  - with command-line flags to the `kube-router` process
+
+  - with annotations to Node objects
+
+- We will use the command-line flags
+
+  (because it will automatically propagate to all nodes)
+
+.footnote[Note: with Calico, this is achieved by creating a BGPPeer CRD.]
+
+---
+
+## Updating kube-router configuration
+
+- We need to pass two command-line flags to the kube-router process

+.exercise[

+  ```
+
+]
+
+---
+
+## Restarting kube-router
+
+- The DaemonSet will not update the pods automatically
+
+  (it is using the default `updateStrategy`, which is `OnDelete`)
+

+
+  (they will be recreated with the updated definition)

+<br/>
+For critical services, we might want to precisely control the update process.
+
+---
+
+## Checking peering status
+
+- We can see informative messages in the output of kube-router:
+  ```
+  time="2019-04-07T15:53:56Z" level=info msg="Peer Up"
+  Key=X.X.X.X State=BGP_FSM_OPENCONFIRM Topic=Peer
+  ```
+
+- We should see the routes of the other clusters show up
+
+- For debugging purposes, the reflector also exports a route to 1.0.0.2/32
+
+- That route will show up like this:
+  ```
+  1.0.0.2     172.31.X.Y    255.255.255.255 UGH   0      0        0 eth0
+  ```
+
+- We should be able to ping the pods of other clusters!
+
+---
+
+## If we wanted to do more ...
+
+- kube-router can also export ClusterIP addresses
+
+  (by adding the flag `--advertise-cluster-ip`)
+
+- They are exported individually (as /32)
+
+- This would allow us to easily access other clusters' services
+
+  (without having to resolve the individual addresses of pods)
+
+- Even better if it's combined with DNS integration

+  (to facilitate name → ClusterIP resolution)

-We want to store the static files (served by `web`) in a ConfigMap.
-
-1. Transform the `static` directory into a ConfigMap.

-   (https://github.com/jpetazzo/wordsmith/tree/master/web/static)
-
-2. Find out where that `static` directory is located in `web`.

-   (for instance, by using `kubectl exec` to investigate)
-
-3. Update the definition of the `web` Deployment to use the ConfigMap.
-
-   (note: fonts and images will be broken; that's OK)
-
-4. Make a minor change in the ConfigMap (e.g. change the text color)

-Level 2: make it so that the number of replicas can be set with `--set replicas=X`.

-
-## Hints
-
-*Scroll one slide at a time to see hints.*
-
---
-
-Use `helm create` to create a new chart.
-
---
-
-Delete the content of the `templates` directory and put your YAML instead.
-
---
-
-Install the resulting chart. Voilà!
-
---
-
-Use `{{ .Values.replicas }}` in the YAML manifest for `words`.
-
---
-
-Also add `replicas: 5` to `values.yaml` to provide a default value.
-
----
-
-## Changing the color
-
-- Fork the repository
-
-- Make sure that your fork has valid Dockerfiles
-
-  (or identify a branch that has valid Dockerfiles)
-
-- Use the following images:
-
-  ctr.run/yourgithubusername/wordsmith/db:branchname
-
-  (replace db with web and words for the other components)
-
-- Change the images and/or CSS in `web/static`
-
-- Commit, push, trigger a rolling update
-
-  (`imagePullPolicy` should be `Always`, which is the default)

-# Exercise — writing YAML
-
-Let's write YAML manifests for the wordsmith app!
-
-It can be a single YAML file or multiple files in a directory.
-
-See next slides for testing instructions and hints.
-
----
-
-## How to test our YAML
-
-If `XYZ` is that YAML file (or directory with YAML files), we should be able to:
-
-1. Create a new namespace, e.g. `foo123`
-
-2. Deploy wordsmith with a single command
-
-   (e.g. `kubectl apply --namespace foo123 -f XYZ`)
-
-3. Find out the connection information for `web`
-
-   (e.g. `kubectl get service web --namespace`)
-
-4. Connect to it and see the wordsmith app
-
-See next slide for hints.
-
----
-
-## Strategies
-
-There are at least three methods to write our YAML.
-
-1. Dump the YAML of existing wordsmith deployments and services.
-
-   (we can dump YAML with `kubectl get -o yaml ...`)
-
-2. Adapt existing YAML (from the docs or dockercoins).
-
-   (for reference, kubercoins is at https://github.com/jpetazzo/kubercoins)
-
-3. Write it entirely from scratch.
-
-See next slide for more hints.

-
-## Adapting YAML
-
-*Scroll one slide at a time to see hints.*
-
---
-
-One option is to start with the YAML from kubercoins.
-
-(see https://github.com/jpetazzo/kubercoins)
-
---
-
-Adapt the YAML of a deployment (e.g. worker) to run "web".
-
---
-
-We need to change the name, labels, selectors, and image.
-
---
-
-Then adapt the YAML of a service (e.g. webui).
-
---
-
-We need to change the name, labels, selectors, possibly port number.
-
---
-
-Repeat for the other components.
