+Most Dockerfile arguments can be passed in two forms:
 
-* On UNIX, to start a new program, we need two system calls:

-

-
-* 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.)

-- 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.

-# Init systems and PID 1
-
-In this chapter, we will consider:
-
-- the role of PID 1 in the world of Docker,
-
-- how to avoid some common pitfalls due to the misuse of init systems.
-
----
-
-## What's an init system?
-
-- On UNIX, the "init system" (or "init" in short) is PID 1.
-
-- It is the first process started by the kernel when the system starts.
-
-- It has multiple responsibilities:
-
-  - start every other process on the machine,
-
-  - reap orphaned zombie processes.
-
----
-
-class: extra-details
-
-## Orphaned zombie processes ?!?
-
-- When a process exits (or "dies"), it becomes a "zombie".
-
-  (Zombie processes show up in `ps` or `top` with the status code `Z`.)
-
-- Its parent process must *reap* the zombie process.
-
-  (This is done by calling `waitpid()` to retrieve the process' exit status.)
-
-- When a process exits, if it has child processes, these processes are "orphaned."
-
-- They are then re-parented to PID 1, init.
-
-- Init therefore needs to take care of these orphaned processes when they exit.
-
----
-
-## Don't use init systems in containers
-
-- It's often tempting to use an init system or a process manager.
-
-  (Examples: *systemd*, *supervisord*...)
-
-- Our containers are then called "system containers".
-
-  (By contrast with "application containers".)
-
-- "System containers" are similar to lightweight virtual machines.
-
-- They have multiple downsides:
-
-  - when starting multiple processes, their logs get mixed on stdout,
-
-  - if the application process dies, the container engine doesn't see it.
-
-- Overall, they make it harder to operate troubleshoot containerized apps.
-
----
-
-## Exceptions and workarounds
-
-- Sometimes, it's convenient to run a real init system like *systemd*.
-
-  (Example: a CI system whose goal is precisely to test an init script or unit file.)
-
-- If we need to run multiple processes: can we use multiple containers?
-
-  (Example: [this Compose file](https://github.com/jpetazzo/container.training/blob/master/compose/simple-k8s-control-plane/docker-compose.yaml) runs multiple processes together.)
-
-- When deploying with Kubernetes:
-
-  - a container belong to a pod,
-
-  - a pod can have multiple containers.
-
----
-
-## What about these zombie processes?
-
-- Our application runs as PID 1 in the container.
-
-- Our application may or may not be designed to reap zombie processes.
-
-- If our application uses subprocesses and doesn't reap them ...
-
-  ... this can lead to PID exhaustion!
-
-  (Or, more realistically, to a confusing herd of zombie processes.)
-
-- How can we solve this?
-
----
-
-## Tini to the rescue
-
-- Docker can automatically provide a minimal `init` process.
-
-- This is enabled with `docker run --init ...`
-
-- It uses a small init system ([tini](https://github.com/krallin/tini)) as PID 1:
-
-  - it reaps zombies,
-
-  - it forwards signals,
-
-  - it exits when the child exits.
-
-- It is totally transparent to our application.
-
-- We should use it if our application creates subprocess but doesn't reap them.
-
----
-
-class: extra-details
-
-## What about Kubernetes?
-
-- Kubernetes does not expose that `--init` option.
-
-- However, we can achieve the same result with [Process Namespace Sharing](https://kubernetes.io/docs/tasks/configure-pod-container/share-process-namespace/).
-
-- When Process Namespace Sharing is enabled, PID 1 will be `pause`.
-
-- That `pause` process takes care of reaping zombies.
-
-- Process Namespace Sharing is available since Kubernetes 1.16.
-
-- If you're using an older version of Kubernetes ...
-
-  ... you might have to add `tini` explicitly to your Docker image.

-
-- Containers within a pod have independent filesystems.

-- Should we upgrade the control plane before or after the kubelets?

-
-- How often should we upgrade?
-
-- How long are versions maintained?

-## Kubernetes uses semantic versioning
-
-- Kubernetes versions look like MAJOR.MINOR.PATCH; e.g. in 1.17.2:
-
-  - MAJOR = 1
-  - MINOR = 17
-  - PATCH = 2
-
-- It's always possible to mix and match different PATCH releases

-  (e.g. 1.16.1 and 1.16.6 are compatible)
-
-- It is recommended to run the latest PATCH release
-
-  (but it's mandatory only when there is a security advisory)
-
----
-
-## Version skew
-
-- API server must be more recent than its clients (kubelet and control plane)
-
-- ... Which means it must always be upgraded first
-
-- All components support a difference of one¹ MINOR version
-
-- This allows live upgrades (since we can mix e.g. 1.15 and 1.16)
-
-- It also means that going from 1.14 to 1.16 requires going through 1.15
-
-.footnote[¹Except kubelet, which can be up to two MINOR behind API server,
-and kubectl, which can be one MINOR ahead or behind API server.]

-## Release cycle

+# Interconnecting clusters
+
+- We assigned different Cluster CIDRs to each cluster
+
+- This allows us to connect our clusters together
+
+- We will leverage kube-router BGP abilities for that
+
+- We will *peer* each kube-router instance with a *route reflector*
+
+- As a result, we will be able to ping each other's pods
+
+---
+
+## 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
+
+  (instructing kube-router to connect to it and exchange route information)
+
+- We should see the routes to other clusters on our nodes
+
+  (in the output of e.g. `route -n` or `ip route show`)
+
+- We should be able to ping pods of other nodes
+
+---
+
+## Starting the route reflector
+
+- Only do this slide if you are doing this on your own
+
+- 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[
+
+- Edit the `kuberouter.yaml` file
+
+- Add the following flags to the kube-router arguments:
+  ```
+  - "--peer-router-ips=`X.X.X.X`"
+  - "--peer-router-asns=64512"
+  ```
+  (Replace `X.X.X.X` with the route reflector address)
+
+- Update the DaemonSet definition:
+  ```bash
+  kubectl apply -f kuberouter.yaml
+  ```
+
+]
+
+---
+
+## Restarting kube-router
+
+- The DaemonSet will not update the pods automatically
+
+  (it is using the default `updateStrategy`, which is `OnDelete`)
+
+- We will therefore delete the pods
+
+  (they will be recreated with the updated definition)
+
+.exercise[
+
+- Delete all the kube-router pods:
+  ```bash
+  kubectl delete pods -n kube-system -l k8s-app=kube-router
+  ```
+
+]
+
+Note: the other `updateStrategy` for a DaemonSet is RollingUpdate.
+<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)
