Enforcing policies in Kubernetes

Kubernetes(K8S) has established itself as the go-to platform for container based workloads and many companies have either already started or going to start soon migrating their workloads onto Kubernetes.

Kubernetes offers so many capabilities out of box, and it exposes many infrastructure related controls to developers. Developers, who are not used to dealing with those infrastructure level concerns, might struggle to grasp all those new controls and abstractions which are not at their disposal. Trainings(such as ones on here) will certainly help to bring developers up to speed with K8S but if we want to really ensure that our applications fulfill all the requirements (such as availability, security, etc.) we want them fulfill, we better do a bit more than just publishing best practices in an intranet wiki page and expect developers to adhere to those best-practices religiously.

But how can you enforce your company’s K8S best practices? How can you create ‘policies’ that covers security and high availability concerns? How can you govern the behavior of a software service?

50+ Useful Kubernetes Tools for 2020 - Part 2

Introduction

Last year, we provided a list of Kubernetes tools that proved so popular we have decided to curate another list of some useful additions for working with the platform—among which are many tools that we personally use here at Caylent. Check out the original tools list here in case you missed it.

According to a recent survey done by Stackrox, the dominance Kubernetes enjoys in the market continues to be reinforced, with 86% of respondents using it for container orchestration.

(State of Kubernetes and Container Security, 2020)

And as you can see below, more and more companies are jumping into containerization for their apps. If you’re among them, here are some tools to aid you going forward as Kubernetes continues its rapid growth.

Improving Kubernetes Security with Open Policy Agent (OPA)

Many multinational organizations now run their applications on microservice architecture inside their cloud environments, and (many) administrators are responsible for defining multiple policies on those environments. These giant IT organizations have extensive infrastructure systems and their systems have their own policy modules or their own built-in authorization systems. This is an excellent solution to a policy issue at enterprise scale (especially if you have the investment and resources to ensure best practice implementation), but such an overall ecosystem can be fragmented, which means if you want to improve control and visibility over who can do what across the stack, you would face a lot of complexity.

Why We Need OPA

Doing a lot of policy enforcement manually is the problem of the past. This does not work in today’s modern environments where everything is very dynamic and ephemeral, where the technology stack is very heterogeneous, where every development team could use a different language. So, the question is, how do you gain granular control over manual policies to automate and streamline their implementation? And the answer is with Open Policy Agent (OPA).

OPA provides technology that helps unify policy enforcement across a wide range of software and enable or empower administrators with more control over their systems. These policies are incredibly helpful in maintaining security, compliance, standardization across environments where we need to define and enforce such policies in a declarative way.

Kubernetes in the Cloud: Strategies for Effective Multi Cloud Implementations

Kubernetes is a highly popular container orchestration platform. Multi cloud is a strategy that leverages cloud resources from multiple vendors. Multi cloud strategies have become popular because they help prevent vendor lock-in and enable you to leverage a wide variety of cloud resources. However, multi cloud ecosystems are notoriously difficult to configure and maintain.

This article explains how you can leverage Kubernetes to reduce multi cloud complexities and improve stability, scalability, and velocity.

Kubernetes: Your Multi Cloud Strategy

Maintaining standardized application deployments becomes more challenging as your number of applications and the technologies they are based on increase. As environments, operating systems, and dependencies differ, management and operations require more effort and extensive documentation.

In the past, teams tried to get around these difficulties by creating isolated projects in the data center. Each project, including its configurations and requirements were managed independently. This required accurately predicting performance and the number of users before deployment and taking down applications to update operating systems or applications. There were many chances for error.

Kubernetes can provide an alternative to the old method, enabling teams to deploy applications independent of the environment in containers. This eliminates the need to create resource partitions and enables teams to operate infrastructure as a unified whole.

In particular, Kubernetes makes it easier to deploy a multi cloud strategy since it enables you to abstract away service differences. With Kubernetes deployments you can work from a consistent platform and optimize services and applications according to your business needs.

The Compelling Attributes of Multi Cloud Kubernetes

Multi cloud Kubernetes can provide multiple benefits beyond a single cloud deployment. Below are some of the most notable advantages.

Stability

In addition to the built-in scalability, fault tolerance, and auto-healing features of Kubernetes, multi cloud deployments can provide service redundancy. For example, you can mirror applications or split microservices across vendors. This reduces the risk of a vendor-related outage and enables you to create failovers.

Microsoft Announces General Availability Of Bridge To Kubernetes

Recently, Microsoft announced the general availability of Bridge to Kubernetes, formerly known as Local Process with Kubernetes. It is an iterative development tool offered in Visual Studio and VS Code, which allows developers to write, test as well as debug microservice code on their development workstations while consuming dependencies and inheriting the existing configuration from a Kubernetes environment.

Nick Greenfield, Program Manager, Bridge to Kubernetes stated in an official blog post, “Bridge to Kubernetes is expanding support to any Kubernetes. Whether you’re connecting to your development cluster running in the cloud, or to your local Kubernetes cluster, Bridge to Kubernetes is available for your end-to-end debugging scenarios.”

Bridge to Kubernetes provides a number of compelling features. Some of them are mentioned below-
