## Making sure Python3 is the default (Mac only)
|
||||
|
||||
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,
|
||||
install it with `brew install python`.
|
||||
|
||||
2) Verify that `python` points to Python3.

```

ls -la /usr/local/bin/python

```

## 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
|
||||

# 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.

- 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.)

## Pods in Docker
|

(Just like when using `docker run --net=container:<container_id>` with the CLI.)

- 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.

# Advanced Rollout
|
||||
|
||||
- In some cases the built-in mechanism of kubernetes is not enough.
|
||||
|
||||
- You want more control on the rollout, include a feedback of the monitoring, deploying
|
||||
on multiple clusters, etc
|
||||
|
||||
- Two "main" strategies exist here:
|
||||
|
||||
- canary deployment
|
||||
- blue/green deployment
|
||||
|
||||
---
|
||||
## Canary deployment
|
||||
|
||||
- focus on one component of the stack
|
||||
|
||||
- deploy a new version of the component close to the production
|
||||
- redirect some portion of prod traffic to new version
|
||||
- scale up new version, redirect more traffic, checking everything is ok
|
||||
- scale down old version
|
||||
- move component to component with the same procedure
|
||||
|
||||
- That's what kubernetes does by default, but does every components at the same time
|
||||
|
||||
- Could be paired with `kubectl wait --for` and applying component sequentially,
|
||||
for hand made canary deployement
|
||||
|
||||
---
|
||||
## Blue/Green deployment
|
||||
|
||||
- focus on entire stack
|
||||
|
||||
- deploy a new stack
|
||||
- check the new stack work as espected
|
||||
- put traffic on new stack, rollback if any goes wrong
|
||||
- garbage collect the previous infra structure
|
||||
|
||||
- there is nothing like that by default in kubernetes
|
||||
|
||||
- helm chart with multiple releases is the closest one
|
||||
|
||||
- could be paired with ingress feature like `nginx.ingress.kubernetes.io/canary-*`
|
||||
|
||||
---
|
||||
## Not hand-made ?
|
||||
|
||||
There is a few additionnal controllers that help achieving those kind of rollout behaviours
|
||||
|
||||
They leverage kubernetes API at different levels to achieve this goal.

- How long are versions maintained?

- All the answers are in [the documentation about version skew policy](https://kubernetes.io/docs/setup/release/version-skew-policy/)!
|
||||
|
||||
- Let's review the key elements together ...
|
||||
|
||||
---
|
||||
|
||||
## 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
|
||||
|
||||
- There is a new PATCH relese whenever necessary
|
||||
|
||||
(every few weeks, or "ASAP" when there is a security vulnerability)
|
||||
|
||||
- There is a new MINOR release every 3 months (approximately)
|
||||
|
||||
- At any given time, three MINOR releases are maintained
|
||||
|
||||
- ... Which means that MINOR releases are maintained approximately 9 months
|
||||
|
||||
- We should expect to upgrade at least every 3 months (on average)

- they can communicate very efficiently over `localhost`
|

|
||||
- Putting them **in different pods** means:
|
||||
|
||||
- they can be scaled separately

- they must communicate over remote IP addresses

# Authoring YAML
|
||||
|
||||
- There are various ways to generate YAML with Kubernetes, e.g.:
|
||||
|
||||
- `kubectl run`
|
||||
|
||||
- `kubectl create deployment` (and a few other `kubectl create` variants)
|
||||
|
||||
- `kubectl expose`
|
||||
|
||||
- When and why do we need to write our own YAML?
|
||||
|
||||
- How do we write YAML from scratch?
|
||||
|
||||
---
|
||||
|
||||
## The limits of generated YAML
|
||||
|
||||
- Many advanced (and even not-so-advanced) features require to write YAML:
|
||||
|
||||
- pods with multiple containers
|
||||
|
||||
- resource limits
|
||||
|
||||
- healthchecks
|
||||
|
||||
- DaemonSets, StatefulSets
|
||||
|
||||
- and more!
|
||||
|
||||
- How do we access these features?
|
||||
|
||||
---
|
||||
|
||||
## We don't have to start from scratch
|
||||
|
||||
- Create a resource (e.g. Deployment)
|
||||
|
||||
- Dump its YAML with `kubectl get -o yaml ...`
|
||||
|
||||
- Edit the YAML
|
||||
|
||||
- Use `kubectl apply -f ...` with the YAML file to:
|
||||
|
||||
- update the resource (if it's the same kind)
|
||||
|
||||
- create a new resource (if it's a different kind)
|
||||
|
||||
- Or: Use The Docs, Luke
|
||||
|
||||
(the documentation almost always has YAML examples)
|
||||
|
||||
---
|
||||
|
||||
## Generating YAML without creating resources
|
||||
|
||||
- We can use the `--dry-run` option
|
||||
|
||||
.exercise[
|
||||
|
||||
- Generate the YAML for a Deployment without creating it:
|
||||
```bash
|
||||
kubectl create deployment web --image nginx --dry-run
|
||||
```
|
||||
|
||||
]
|
||||
|
||||
- We can clean up that YAML even more if we want
|
||||
|
||||
(for instance, we can remove the `creationTimestamp` and empty dicts)
|
||||
|
||||
---
|
||||
|
||||
## Using `--dry-run` with `kubectl apply`
|
||||
|
||||
- The `--dry-run` option can also be used with `kubectl apply`
|
||||
|
||||
- However, it can be misleading (it doesn't do a "real" dry run)
|
||||
|
||||
- Let's see what happens in the following scenario:
|
||||
|
||||
- generate the YAML for a Deployment
|
||||
|
||||
- tweak the YAML to transform it into a DaemonSet
|
||||
|
||||
- apply that YAML to see what would actually be created
|
||||
|
||||
---
|
||||
|
||||
## The limits of `kubectl apply --dry-run`
|
||||
|
||||
.exercise[
|
||||
|
||||
- Generate the YAML for a deployment:
|
||||
```bash
|
||||
kubectl create deployment web --image=nginx -o yaml > web.yaml
|
||||
```
|
||||
|
||||
- Change the `kind` in the YAML to make it a `DaemonSet`:
|
||||
```bash
|
||||
sed -i s/Deployment/DaemonSet/ web.yaml
|
||||
```
|
||||
|
||||
- Ask `kubectl` what would be applied:
|
||||
```bash
|
||||
kubectl apply -f web.yaml --dry-run --validate=false -o yaml
|
||||
```
|
||||
|
||||
]
|
||||
|
||||
The resulting YAML doesn't represent a valid DaemonSet.
|
||||
|
||||
---
|
||||
|
||||
## Server-side dry run
|
||||
|
||||
- Since Kubernetes 1.13, we can use [server-side dry run and diffs](https://kubernetes.io/blog/2019/01/14/apiserver-dry-run-and-kubectl-diff/)
|
||||
|
||||
- Server-side dry run will do all the work, but *not* persist to etcd
|
||||
|
||||
(all validation and mutation hooks will be executed)
|
||||
|
||||
.exercise[
|
||||
|
||||
- Try the same YAML file as earlier, with server-side dry run:
|
||||
```bash
|
||||
kubectl apply -f web.yaml --server-dry-run --validate=false -o yaml
|
||||
```
|
||||
|
||||
]
|
||||
|
||||
The resulting YAML doesn't have the `replicas` field anymore.
|
||||
|
||||
Instead, it has the fields expected in a DaemonSet.
|
||||
|
||||
---
|
||||
|
||||
## Advantages of server-side dry run
|
||||
|
||||
- The YAML is verified much more extensively
|
||||
|
||||
- The only step that is skipped is "write to etcd"
|
||||
|
||||
- YAML that passes server-side dry run *should* apply successfully
|
||||
|
||||
(unless the cluster state changes by the time the YAML is actually applied)
|
||||
|
||||
- Validating or mutating hooks that have side effects can also be an issue
|
||||
|
||||
---
|
||||
|
||||
## `kubectl diff`
|
||||
|
||||
- Kubernetes 1.13 also introduced `kubectl diff`
|
||||
|
||||
- `kubectl diff` does a server-side dry run, *and* shows differences
|
||||
|
||||
.exercise[
|
||||
|
||||
- Try `kubectl diff` on the YAML that we tweaked earlier:
|
||||
```bash
|
||||
kubectl diff -f web.yaml
|
||||
```
|
||||
|
||||
<!-- ```wait status:``` -->
|
||||
|
||||
]
|
||||
|
||||
Note: we don't need to specify `--validate=false` here.
|
||||
|
||||
---
|
||||
|
||||
## Advantage of YAML
|
||||
|
||||
- Using YAML (instead of `kubectl run`/`create`/etc.) allows to be *declarative*
|
||||
|
||||
- The YAML describes the desired state of our cluster and applications
|
||||
|
||||
- YAML can be stored, versioned, archived (e.g. in git repositories)
|
||||
|
||||
- To change resources, change the YAML files
|
||||
|
||||
(instead of using `kubectl edit`/`scale`/`label`/etc.)
|
||||
|
||||
- Changes can be reviewed before being applied
|
||||
|
||||
(with code reviews, pull requests ...)
|
||||
|
||||
- This workflow is sometimes called "GitOps"
|
||||
|
||||
(there are tools like Weave Flux or GitKube to facilitate it)
|
||||
|
||||
---
|
||||
|
||||
## YAML in practice
|
||||
|
||||
- Get started with `kubectl run`/`create`/`expose`/etc.
|
||||
|
||||
- Dump the YAML with `kubectl get -o yaml`
|
||||
|
||||
- Tweak that YAML and `kubectl apply` it back
|
||||
|
||||
- Store that YAML for reference (for further deployments)
|
||||
|
||||
- Feel free to clean up the YAML:
|
||||
|
||||
- remove fields you don't know
|
