From Docker Compose to Kubernetes

There are multiple ways to deploy a cloud-native app in an efficient environment. Whether you have a single service or hundreds of microservices, you can configure your cloud cluster for maximum performance. The two most popular ways are by utilizing Kubernetes and Docker Compose, with the former being more popular in today’s market.

Docker Compose has its advantages compared to Kubernetes, but that doesn’t mean it is the best solution in the long run. Kubernetes is the more robust of the two when it comes to solutions that require scaling up and staying lean. Fortunately, migrating from Docker Compose to Kubernetes is a lot easier than ever before.

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.

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.

How To Build A Kubernetes Backend In Compose CLI ?

Docker Compose is a great tool from Docker, it is used by millions to deploy and manage multi-containers applications. Docker Compose is basically 2 things:

  • The Compose file is a specification in yaml (named docker-compose.yaml by default) that Docker Compose takes as input. This file defines the components of a containerized application and how they are connected together. It should be written according to the Compose specification whose details are available in this repository
  • Docker Compose is the tool that processes this Compose file: it checks that it is written according to the Compose specification and deploys the application components

Anca Iordache from Docker, explains the move to the Compose Spec into the open and how she has started to develop a kube backend for the Compose CLI as a side project:

“The Compose format is very popular among developers due to its simplicity and there was always a lot of interest in having tools to deploy Compose files on platforms other than a single Docker Engine or Swarm. To make Compose go beyond Docker and Swarm, early in 2020, we opened the Compose specification to enable anybody to build tools around it. We used the new open specification and reference libraries to build support for Amazon ECS and Microsoft ACI into the Docker CLI for deploying Compose apps on these platforms. An obvious next target was Kubernetes as it is highly popular and there is a lot of interest in deploying Compose apps onto it. We wrote an initial proof of concept to test this integration but it hasn’t been added to Docker’s product roadmap yet. I have picked it up as my hack project to continue making progress with this integration. The current code for the Kubernetes backend can be found in the public repository docker/compose-cli and everybody is welcome to contribute to it.”

Docker Explained: Docker Architecture | Docker Registries

Following the second video about Docker basics, in this video, I explain Docker architecture and explain the different building blocks of the docker engine; docker client, API, Docker Daemon. I also explain what a docker registry is and I finish the video with a demo explaining and illustrating how to use Docker hub

In this video lesson you will learn:

  • What is Docker Host
  • What is Docker Engine
  • Learn about Docker Architecture
  • Learn about Docker client and Docker Daemon
  • Docker Hub and Registries
  • Simple demo to understand using images from registries

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.

Docker and Kubernetes Updates in IntelliJ IDEA 2021.2

Apart from other helpful features we’ve described over the EAP period, IntelliJ IDEA 2021.2 contains some useful updates for Kubernetes and Docker. You can test them now by getting the latest build from our website, the free Toolbox App, or snaps for Ubuntu.

The following feature overview will help you browse through numerous changes.

Docker Compose

Services synchronization

Previously your IDE displayed only running services in the Services tool window. Starting with this EAP, you can make all of your Docker Compose applications appear there, even if they are not running. To display them, you can click the cycle arrows icon right in the editor window.

Kubernetes

Support for alias in Helm chart dependencies

In Helm, charts can depend on other charts. The dependencies section allows you to manage chart dependencies. This section is located in Chart.yaml (api v2) or in requirements.yaml (api v1). Apart from the default nameversion, and repository fields, each required entry can contain the alias field, which we’ve added support for in v2021.2.
