What is Kubernetes?

Kubernetes is an open-source container orchestration technology system .Kubernetes is mainly used for automating deployment, scaling and management of containerized applications.

Kubernetes was originally designed by Google and then open sourced.And from then to now Kubernetes is maintained by the Cloud Native Computing Foundation.

Kubernetes  aims to provide a "platform for automating deployment, scaling, and operations of application containers across clusters of hosts It works with a range of container tools, including Docker.

Kubernetes is a portable as well as extensible platform for managing containerized workloads and services, that facilitates both declarative configuration and automation. Kubernetes  has a large, rapidly growing ecosystem. There are widely availablity in Kubernetes services, support, and tools.

Google open-sourced the Kubernetes project in 2014. Kubernetes builds upon a decade and a half of experience that Google has with running production workloads at scale, combined with best-of-breed ideas and practices from the community.

Even though Kubernetes provides a lot of functionality, there are always new scenarios that would benefit from new features. Application-specific workflows can be streamlined to accelerate developer velocity. Ad hoc orchestration that is acceptable initially often requires robust automation at scale. This is why Kubernetes was also designed to serve as a platform for building an ecosystem of components and tools to make it easier to deploy, scale, and manage applications.

Labels in Kubernetes empower users to organize their resources however they please. Annotations enable users to decorate resources with custom information to facilitate their workflows and provide an easy way for management tools to checkpoint state.

The Kubernetes control plane is mainly built upon the same APIs that are available to developers and users. Users can write their own controllers, such as schedulers, with their own APIs that can be targeted by a general-purpose command-line tool.

This design has enabled a number of other systems to build the Kubernetes.

On the other hand Kubernetes is not a traditional or all-inclusive Platform as a Service( PaaS) system. Since Kubernetes operates at the container level rather than at the hardware level, it provides some generally applicable features common to PaaS offerings, such as deployment, scaling, load balancing, logging, and monitoring. However, Kubernetes is not monolithic, and these default solutions are optional and pluggable. Kubernetes provides the building blocks for building developer platforms but preserves user choice and flexibility where it is important.

 

Here are some advantages of Kubernetes

Firstly Kubernetes does not limit the types of applications supported. Moreover, Kubernetes aims to support an extremely diverse variety of workloads, including stateless and stateful even data-processing workloads. Thatswhy If an application can run in a container, it should run great on Kubernetes.

Kubernetes never  deploy source code and does not build your application. Continuous Integration, Delivery, and Deployment (CI/CD) workflows are determined by organization cultures and preferences as well as technical requirements.

Kubernetes does not provide application-level services, such as middleware (e.g., message buses), data-processing frameworks (for example, Spark), databases like MySQL, caches as built-in services. Such components can run on Kubernetes, and/or can be accessed by applications running on Kubernetes through portable mechanisms, such as the Open Service Broker.

Kubernetes never dictate logging, monitoring, or alerting solutions. It provides some integrations as proof of concept, and mechanisms to collect and export metrics.

Kubernetes does not also provide nor mandate a configuration language/system (e.g., jsonnet). It provides a declarative API that may be targeted by arbitrary forms of declarative specifications.

Kubernetes never provide nor adopt any comprehensive machine configuration, maintenance, management, or self-healing systems.

Though Kubernetes is not a mere orchestration system. In fact,kubernetes eliminates the need for orchestration. In contrast, Kubernetes is comprised of a set of independent, composable control processes.Kubernetes also drive the current state continuously towards the provided desired state.

 

What is Kubernetes for ?

Kubernetes is an open source system for managing containerized applications across multiple hosts, providing basic mechanisms for deployment, maintenance, and scaling of applications.In short, Kubernetes is a container orchestration tool from Google.


How Does Kubernetes work?

Kubernetes can mainly defines as a set of building blocks.Kubernetes collectively provides mechanisms that deploy, maintain and scale applications. Kubernetes is loosely coupled and extensible to meet different workloads. This extensibility is provided in large part by the Kubernetes API, which is used by internal components as well as extensions and containers that run on Kubernetes


There are some key components which are widely used is Kuberntes are

  • Pods

  • Labels and selectors

  • Controllers

  • Services


What is the pod in Kubernetes

A Kubernetes pod is a group of containers. Pods can be deployed together on the same host. If you frequently deploy single containers, you can generally replace the word "pod" with "container" and accurately understand the concept.

Pods operate at one level higher than individual containers because it's very common to have a group of containers work together to produce an artifact or process a set of work.

For example, consider this pair of containers: a caching server and a cache "warmer". You could build these two functions into a single container, but now they can each be tailored to the specific task and shared between different projects.

 

What is labels and selectors in Kubernetes?

Labels and selectors are the primary grouping mechanism in Kubernetes and determine the components an operation applies to.

Labels are key-value pairs that are attached to Kubernetes objects, such as Pods. They are intended to be used to specify object attributes which are meaningful and relevant to users, while not directly impacting implying semantics of the core system.

Unlike names and UIDs, labels in Kubernetes do not provide uniqueness. In general, we expect many objects to carry the same label(s).

 Via a label selector, the client/user can identify a set of objects. The label selector is the core grouping primitive in Kubernetes.

The API currently supports two types of selectors: equality-based and set-based. A label selector can be made of multiple requirements which are comma-separated. In the case of multiple requirements, all must be satisfied so the comma separator acts as a logical AND (&&) operator.


What is Controllers  in Kubernetes?

A controller is a reconciliation loop that drives actual cluster state toward the desired cluster state. It does this by managing a set of pods. One kind of controller is a replication controller, which handles replication and scaling by running a specified number of copies of a pod across the cluster. It also handles creating replacement pods if the underlying node fails. Other controllers that are part of the core Kubernetes system include a "DaemonSet Controller" for running exactly one pod on every machine or some subset of machines and a "Job Controller" for running pods that run to completion, as part of a batch job. The set of pods that a controller manages is determined by Kubernetes label selectors that are part of the controller’s definition.


What is Services in Kubernetes?

A Kubernetes service is a set of pods which can work together, such as one tier of a multi-tier application. The set of pods that constitute a service are defined by a label selector.Kubernetes provides service discovery and request routing by assigning a stable IP address and DNS name to the service, and load balances traffic in a round-robin manner to network connections of that IP address among the pods matching the selector even as failures cause the pods to move from machine to machine.By default, a service is exposed inside a cluster but a service can also be exposed outside a kubernetes cluster.


Why you should start learning Kubernetes?

When our clients ask us to create a highly available distributed system, we usually recommend Kubernetes, because Kubernetes is really easy to use and even though it has a steep initial learning curve and kubernetes still a lot more simple than other competing orchestration engines.

Kubernetes also works perfectly with Node apps because it's based on Docker.Thatswhy  you can run any kind of application using Kubernetes.

As we all know kubernetes is a open source project spun out of Google which  automates the process of deploying and managing multi-container applications at scale. While Kubernetes works mainly with Docker, it can also work with any container system that conforms to the Open Container Initiative (OCI) standards for container image formats and runtimes.

And because Kubernetes is open source, with relatively few restrictions on how it can be used, it can be used freely by anyone who wants to run containers, most anywhere they want to run them.

Kubernetes introduces new abstractions and concepts, and the learning curve for Kubernetes is high so it is only normal to ask what the long-term payoffs are for using Kubernetes. Here’s a rundown of some of the specific ways running apps inside Kubernetes becomes easier.

Kubernetes manages app health, replication, load balancing, and hardware resource allocation for you. One of the most basic duties Kubernetes takes off your hands is the busywork of keeping an application up, running, and responsive to user demands. Apps that become “unhealthy,” or don’t conform to the definition of health you describe for them, can be automatically healed using kubernetes.

Another benefit of Kubernetes is that it maximizes the use of hardware resources including memory, storage I/O, and network bandwidth. Applications can have soft and hard limits set on their resource usage. Many apps that use minimal resources can be packed together on the same hardware; apps that need to stretch out can be placed on systems. And again, rolling out updates across a cluster, or rolling back if updates break, can be automated.

Kubernetes Helm charts ease the deployment of preconfigured applications. Package managers such as Debian Linux’s APT and Python’s Pip save users the trouble of manually installing and configuring an application. This is especially handy when an application has multiple external dependencies.

Helm is something like a package manager for Kubernetes. Many popular software applications must run as multiple, ganged-together containers in Kubernetes. Helm provides a definition mechanism, a “chart,” that describes how a given piece of software can be run as a group of containers inside Kubernetes.

Kubernetes simplifies management of storage, secrets, and other application-related resources. Containers are meant to be immutable; whatever you put into them isn’t supposed to change. But applications need state so it means they need a reliable way to deal with external storage volumes. That’s made all the more complicated by the way containers live, die, and are reborn across the lifetime of an app.

Kubernetes always allow containers and apps to deal with storage in the same decoupled way as other resources. Many common kinds of storage, from Amazon EBS volumes to plain old NFS shares, can be accessed via Kubernetes storage drivers, called volumes. Normally, volumes are bound to a specific pod, but a volume subtype called a “Persistent Volume” can be used for data which needs to live on independently of any pod in Kubernetes.

Sometimes these containers need to work with “secrets” which is nothing but credentials like API keys or service passwords that you don’t want hardwired in a container or stashed openly on a disk volume. While third-party solutions are available for this, like Docker secrets and HashiCorp Vault,

In that case, Kubernetes uses its own mechanism of handling secrets. For instance, Etcd must be configured to use SSL/TLS when sending information including secrets between nodes, rather than in plaintext.

Kubernetes apps can run in hybrid and multi-cloud environments. One of the long-standing dreams of cloud computing is to be able to run any app in any cloud or any mix of clouds public or private.

Kubernetes’s architecture makes use of various concepts and abstractions. Some of these are variations on existing, familiar notions, but others are specific to Kubernetes.

The highest-level Kubernetes abstraction, the cluster, refers to the group of machines running Kubernetes (itself a clustered application) and the containers managed by it. A Kubernetes cluster must have a master, the system that commands and controls all the other Kubernetes machines in the cluster. A highly available Kubernetes cluster replicates the master’s facilities across multiple machines. But only one master at a time runs the job scheduler and controller-manager.

Each cluster contains Kubernetes nodes. This Kubernetes nodes might be physical machines or VMs. Again, the idea is abstraction: whatever the app is running on, Kubernetes handles deployment on that substrate. It is also possible to ensure that certain containers run only on VMs or only on bare metal.

Nodes run pods, the most basic Kubernetes objects that can be created or managed. Each pod represents a single instance of an application or running process in Kubernetes and consists of one or more containers. On the other hand Kubernetes starts, stops, and replicates all containers in a pod as a group. Pods keep the user’s attention on the application, rather than on the containers themselves.

Pods are created and destroyed on nodes as needed to conform to the desired state specified by the user in the pod definition. Kubernetes provides an abstraction called a controller for dealing with the logistics of how pods are spun up, rolled out, and spun down.

Controllers come in a few different flavors depending on the kind of application being managed. For instance, the recently introduced “StatefulSet” controller is used to deal with applications that need persistent state. Another kind of controller, the deployment, is used to scale an app up or down, update an app to a new version, or roll back an app to a known-good version if there’s a problem.

Because pods in Kubernetes  live and die as needed, we need a different abstraction for dealing with the application lifecycle. An application is supposed to be a persistent entity, even when the pods running the containers that comprise the application aren’t themselves persistent.

To that end, Kubernetes provides an abstraction called a service.

A service describes how a given group of pods or other Kubernetes objects can be accessed via the network. As the Kubernetes documentation puts it, the pods that constitute the back end of an application might change, but the front end shouldn’t have to know about that or track it. Services make this possible.

A few more pieces internal to Kubernetes round out the picture. The scheduler parcels out workloads to nodes so that they’re balanced across resources and so that deployments meet the requirements of the application definitions. The controller manager ensures the state of the system—applications, workloads, etc.—matches the desired state defined in Etcd’s configuration settings.

Audio quality is not good; instructor's pace is very irregular, big gaps between phrases / sentences, which themselves are uttered very quickly. This makes the video too slow on 1-1.5x speed and very difficult to comprehend on 2x speed.

Section 2, Lecutre 29. Not sure how pods(nginix) got created is not shown when the nodes created. This should have been avoided in the first case. it created confusion. Not sure why node1 is not in ready state was clearly explained. No proper troubleshooting. No proper validation of resources before creating node2 which did not host the mysql pod. Not even tried deployed by increasing virtual resources at Vagrant. Last but not the least, not explained why pod is not getting deleted for nginix and reason behind its creation multiple times despite pod being deleted. I guess the key concepts were not given proper explanation. Waste of time and money. Inexperienced trainer which i personally feel and better exposure to the environment.

Kubernetes does a really good job when it comes to container orchestration. It offers vast amount of feature sets, which allow applying modern container-based management techniques also for older applications. Being able to write custom operators allows to deploy very sophisticated infrastructure lifecycle scenarios. It has reduced time-to-live for our services by the order of magnitude. It also helps to avoid vendor lock-in and allows easy portability of your tech stack between various infrastructure providers, both in cloud and on premise. The trainer is awesome....
