Im under the impression that the dash version "walk-through" is correct as that seems to be the most commonly used. Most spell checks flag "walkthrough" as not a word, so I'm pretty sure that's out. Most grammar checks to not seem to flag the spaced version "walk through", however, so I'm not 100% sure.
In this case, walkthrough is the correct one. The why is a lot more complicated, and I for one am somewhat confused coming from a closed compound language. Even my spell check on this page is telling me that "walkthrough" is wrong, even if it is right in this sense.
The general rule with compound words seems to be to a point arbitrary (which languages are as an excuse for not being universally the same); there is a certain agreement among certain house rules as to what is right and what isn't correct. Walkthrough seems to be the accepted compound rule amongst modern users.

A student who wishes to participate in Commencement in June, but who will not have completed all degree requirements by that time, must meet certain criteria to be eligible to be considered a "walkthrough."
Horizontal scaling means that the response to increased load is to deploy morePods.This is different from vertical scaling, which for Kubernetes would meanassigning more resources (for example: memory or CPU) to the Pods that are alreadyrunning for the workload.
If the load decreases, and the number of Pods is above the configured minimum,the HorizontalPodAutoscaler instructs the workload resource (the Deployment, StatefulSet,or other similar resource) to scale back down.
You need to have a Kubernetes cluster, and the kubectl command-line tool mustbe configured to communicate with your cluster. It is recommended to run this tutorial on a cluster with at least two nodes that are not acting as control plane hosts. If you do not already have acluster, you can create one by usingminikubeor you can use one of these Kubernetes playgrounds:
To follow this walkthrough, you also need to use a cluster that has aMetrics Server deployed and configured.The Kubernetes Metrics Server collects resource metrics fromthe kubelets in your cluster, and exposes those metricsthrough the Kubernetes API,using an APIService to addnew kinds of resource that represent metric readings.
You will shortly run a command that creates a HorizontalPodAutoscaler that maintainsbetween 1 and 10 replicas of the Pods controlled by the php-apache Deployment thatyou created in the first step of these instructions.
Roughly speaking, the HPA controller will increase and decreasethe number of replicas (by updating the Deployment) to maintain an average CPU utilization across all Pods of 50%.The Deployment then updates the ReplicaSet - this is part of how all Deployments work in Kubernetes -and then the ReplicaSet either adds or removes Pods based on the change to its .spec.
Please note that the current CPU consumption is 0% as there are no clients sending requests to the server(the TARGET column shows the average across all the Pods controlled by the corresponding deployment).
Next, see how the autoscaler reacts to increased load.To do this, you'll start a different Pod to act as a client. The container within the client Podruns in an infinite loop, sending queries to the php-apache service.
Notice that the targetCPUUtilizationPercentage field has been replaced with an array called metrics.The CPU utilization metric is a resource metric, since it is represented as a percentage of a resourcespecified on pod containers. Notice that you can specify other resource metrics besides CPU. By default,the only other supported resource metric is memory. These resources do not change names from clusterto cluster, and should always be available, as long as the
metrics.k8s.io API is available.
You can also specify resource metrics in terms of direct values, instead of as percentages of therequested value, by using a target.type of AverageValue instead of Utilization, andsetting the corresponding target.averageValue field instead of the target.averageUtilization.
There are two other types of metrics, both of which are considered custom metrics: pod metrics andobject metrics. These metrics may have names which are cluster specific, and require a moreadvanced cluster monitoring setup.
The first of these alternative metric types is pod metrics. These metrics describe Pods, andare averaged together across Pods and compared with a target value to determine the replica count.They work much like resource metrics, except that they only support a target type of AverageValue.
The second alternative metric type is object metrics. These metrics describe a differentobject in the same namespace, instead of describing Pods. The metrics are not necessarilyfetched from the object; they only describe it. Object metrics support target types ofboth Value and AverageValue. With Value, the target is compared directly to the returnedmetric from the API. With AverageValue, the value returned from the custom metrics API is dividedby the number of Pods before being compared to the target. The following example is the YAMLrepresentation of the requests-per-second metric.
If you provide multiple such metric blocks, the HorizontalPodAutoscaler will consider each metric in turn.The HorizontalPodAutoscaler will calculate proposed replica counts for each metric, and then choose theone with the highest replica count.
Then, your HorizontalPodAutoscaler would attempt to ensure that each pod was consuming roughly50% of its requested CPU, serving 1000 packets per second, and that all pods behind the main-routeIngress were serving a total of 10000 requests per second.
Many metrics pipelines allow you to describe metrics either by name or by a set of additionaldescriptors called labels. For all non-resource metric types (pod, object, and external,described below), you can specify an additional label selector which is passed to your metricpipeline. For instance, if you collect a metric http_requests with the verblabel, you can specify the following metric block to scale only on GET requests:
This selector uses the same syntax as the full Kubernetes label selectors. The monitoring pipelinedetermines how to collapse multiple series into a single value, if the name and selectormatch multiple series. The selector is additive, and cannot select metricsthat describe objects that are not the target object (the target pods in the case of the Podstype, and the described object in the case of the Object type).
Applications running on Kubernetes may need to autoscale based on metrics that don't have an obviousrelationship to any object in the Kubernetes cluster, such as metrics describing a hosted service withno direct correlation to Kubernetes namespaces. In Kubernetes 1.10 and later, you can address this use casewith external metrics.
Using external metrics requires knowledge of your monitoring system; the setup issimilar to that required when using custom metrics. External metrics allow you to autoscale your clusterbased on any metric available in your monitoring system. Provide a metric block with aname and selector, as above, and use the External metric type instead of Object.If multiple time series are matched by the metricSelector,the sum of their values is used by the HorizontalPodAutoscaler.External metrics support both the Value and AverageValue target types, which function exactly the sameas when you use the Object type.
For example if your application processes tasks from a hosted queue service, you could add the followingsection to your HorizontalPodAutoscaler manifest to specify that you need one worker per 30 outstanding tasks.
When possible, it's preferable to use the custom metric target types instead of external metrics, since it'seasier for cluster administrators to secure the custom metrics API. The external metrics API potentially allowsaccess to any metric, so cluster administrators should take care when exposing it.
When using the autoscaling/v2 form of the HorizontalPodAutoscaler, you will be able to seestatus conditions set by Kubernetes on the HorizontalPodAutoscaler. These status conditions indicatewhether or not the HorizontalPodAutoscaler is able to scale, and whether or not it is currently restrictedin any way.
For this HorizontalPodAutoscaler, you can see several conditions in a healthy state. The first,AbleToScale, indicates whether or not the HPA is able to fetch and update scales, as well aswhether or not any backoff-related conditions would prevent scaling. The second, ScalingActive,indicates whether or not the HPA is enabled (i.e. the replica count of the target is not zero) andis able to calculate desired scales. When it is False, it generally indicates problems withfetching metrics. Finally, the last condition, ScalingLimited, indicates that the desired scalewas capped by the maximum or minimum of the HorizontalPodAutoscaler. This is an indication thatyou may wish to raise or lower the minimum or maximum replica count constraints on yourHorizontalPodAutoscaler.
