<section id='an-api' data-markdown>
## Kubernetes provides an API
API object primitives include the following attributes:
1. kind
2. apiVersion
3. metadata
4. spec
5. status
*mostly true
</section>
<section data-transition="linear" id='terminology' data-markdown>
### Basic K8s Terminology
1. [node](#/node)
2. [pod](#/po)
3. [service](#/svc)
4. [deployment](#/deploy)
5. [replicaSet](#/rs)
</section>
</section>
<section>
<section data-transition="linear" id='node' data-markdown>
### Node
A node is a host machine (physical or virtual) where containerized processes run.
Node activity is managed via one or more Master instances.
</section>
<section>
<p>Try using <code>kubectl</code> to list resources by type:</p>
<pre><code contenteditable>kubectl get nodes</code></pre>
<p>Request the same info, but output the results as structured yaml:</p>
<pre><code contenteditable>kubectl get nodes -o yaml</code></pre>
<p>Fetch an individual resource by <code>type/id</code>, output as <code>json</code>:</p>
<pre><code contenteditable>kubectl get node/minikube -o json</code></pre>
<p>View human-readable API output:</p>
<pre><code contenteditable>kubectl describe node/minikube</code></pre>
</section>
<section data-markdown>
### Observations:
* Designed to exist on multiple machines (distributed system)
* high availability of nodes
* platform scale out
* The API ambidextriously supports both json and yaml
</section>
</section>
<section>
<section data-transition="linear" id='po' data-markdown>
### Pod
A group of one or more co-located containers. Pods represent your minimum increment of scale.
> "Pods Scale together, and they Fail together" @theSteve0
</section>
<section>
<p>List resources by type:</p>
<pre><code contenteditable>kubectl get pods</code></pre>
<p>Create a new resource based on a json object specification:</p>
<pre><code contenteditable>curl https://raw.githubusercontent.com/ryanj/metrics-k8s/master/pod.json</code></pre>
<pre><code contenteditable>kubectl create -f https://raw.githubusercontent.com/ryanj/metrics-k8s/master/pod.json</code></pre>
<p>List resources by type:</p>
<pre><code contenteditable>kubectl get pods</code></pre>
<p>Fetch a resource by type and id, output the results as <code>yaml</code>:</p>
<pre><code contenteditable>kubectl get pod metrics-k8s -o yaml</code></pre>
<p>Notice any changes?</p>
</section>
<section data-markdown>
### Observations:
* pods are scheduled to be run on nodes
* asyncronous fulfilment of requests
* declarative specifications
* automatic health checks, lifecycle management for containers (processes)
</section>
</section>
<section>
<section data-transition="linear" id='svc' data-markdown>
### Service
Services (svc) establish a single endpoint for a collection of replicated pods, distributing inbound traffic based on label selectors
In our K8s modeling language they represent a load balancer. Their implementation often varies per cloud provider
</section>
<section id='services'>
<h3>Contacting your App</h3>
<p>Expose the pod by creating a new <code>service</code> (or "loadbalancer"):</p>
<pre><code contenteditable>kubectl expose pod/metrics-k8s --port 2015 --type=NodePort</code></pre>
<p>Contact your newly-exposed pod using the associated service id:</p>
<pre><code contenteditable>minikube service metrics-k8s</code></pre>
<p>Schedule a pod to be deleted:</p>
<pre><code contenteditable>kubectl delete pod metrics-k8s</code></pre>
<p>Contact the related service. What happens?:</p>
<pre><code contenteditable>minikube service metrics-k8s</code></pre>
<p>Delete the service:</p>
<pre><code contenteditable>kubectl delete service metrics-k8s</code></pre>
</section>
<section data-markdown>
### Observations:
* *"service"* basically means *"loadbalancer"*
* Pods and Services exist independently, have disjoint lifecycles
</section>
</section>
<section>
<section data-transition="linear" id='deploy' data-markdown>
### Deployment
A `deployment` helps you specify container runtime requirements (in terms of pods)
</section>
<section>
<p>Create a specification for your <code>deployment</code>:</p>
<pre><code contenteditable>kubectl run metrics-k8s --image=quay.io/ryanj/metrics-k8s \
--expose --port=2015 --service-overrides='{ "spec": { "type": "NodePort" } }' \
--dry-run -o yaml > deployment.yaml</code></pre>
<p>View the generated deployment spec file:</p>
<pre><code contenteditable>cat deployment.yaml</code></pre>
<p><i><b>Bug!:</b></i> Edit the file, adding "<code>---</code>" (on it's own line) between resource 1 and resource 2 for a workaround.</p>
<p>Can you think of another way to fix this issue? json compatible?</p>
</section>
<section>
<p>Create a new resource based on your yaml specification:</p>
<pre><code contenteditable>kubectl create -f deployment.yaml</code></pre>
<p>List resources by type:</p>
<pre><code contenteditable>kubectl get po,svc</code></pre>
<p>Connect to your new deployment via the associated service id:</p>
<pre><code contenteditable>minikube service metrics-k8s</code></pre>
</section>
<section id='replication'>
<h2>Replication</h2>
<p>Scale up the <code>metrics-k8s</code> deployment to 3 replicas:</p>
<pre><code contenteditable>kubectl scale deploy/metrics-k8s --replicas=3</code></pre>
<p>List pods:</p>
<pre><code contenteditable>kubectl get po</code></pre>
</section>
<section>
<p>Edit <code>deploy/metrics-k8s</code>, setting <code>spec.replicas</code> to <code>5</code>:</p>
<pre><code contenteditable>kubectl edit deploy/metrics-k8s -o json</code></pre>
<p>Save and quit. What happens?</p>
<pre><code contenteditable>kubectl get pods</code></pre>
</section>
<section id='autorecovery'>
<h2>AutoRecovery</h2>
<p>Watch for changes to <code>pod</code> resources:</p>
<pre><code contenteditable>kubectl get pods --watch</code></pre>
<p>In another terminal, delete several pods by id:</p>
<pre><code contenteditable>kubectl delete pod $(kubectl get pods | grep ^metrics-k8s | cut -f1 -s -d' ' | head -n 3 | tr '\n' ' ')</code></pre>
<p>What happend? How many pods remain?</p>
<pre><code contenteditable>kubectl get pods</code></pre>
</section>
<section data-markdown>
### Observations:
* Use the `--dry-run` flag to generate new resource specifications
* A deployment spec contains a pod spec
</section>
</section>
<section>
<section data-transition="linear" id='rs' data-markdown>
### ReplicaSet
A `replicaset` provides replication and lifecycle management for a specific image release
</section>
<section>
<p>Watch deployments (leave this running until the 'cleanup' section):</p>
<pre><code contenteditable>kubectl get deploy --watch</code></pre>
<p>View the current state of your deployment:</p>
<pre><code contenteditable>minikube service metrics-k8s</code></pre>
</section>
<section>
<h3>Rollouts</h3>
<p>Update your deployment's image spec to rollout a new release:</p>
<pre><code contenteditable>kubectl set image deploy/metrics-k8s metrics-k8s=quay.io/ryanj/metrics-k8s:v1</code></pre>
<p>Reload your browser to view the state of your deployment</p>
<pre><code contenteditable>kubectl get rs,deploy</code></pre>
</section>
<section>
<h3>Rollbacks</h3>
<p>View the list of previous rollouts:</p>
<pre><code contenteditable>kubectl rollout history deploy/metrics-k8s</code></pre>
<p>Rollback to the previous state:</p>
<pre><code contenteditable>kubectl rollout undo deployment metrics-k8s</code></pre>
<p>Reload your browser to view the state of your deployment</p>
</section>
<section>
<h3>Cleanup</h3>
<p>Cleanup old resources if you don't plan to use them:</p>
<pre><code contenteditable>kubectl delete service,deployment metrics-k8s</code></pre>
<p>Close any remaining <code>--watch</code> listeners</p>
</section>
<section data-markdown>
### Observations:
* The API allows for watch operations (in addition to get, set, list)
* ReplicaSets provide lifecycle management for pod resources
* Deployments create ReplicaSets to manage pod replication per rollout (per change in podspec: image:tag, environment vars)
