Docker vs Kubernetes vs Ansible: Which Is the Best DevOps Tool?

What is DevOps Tool?

DevOps tools are designed to integrate and deliver fast IT service by improving communication between developer and operator.

With the support of these tools, production and activity teams will work together to deliver the software services.

It has become an integral part of various industry industries, ranging from startups to large corporations using DevOps resources to support their business processes, and project planning before delivery.

The DevOps helps organizations adjust to evolving market requirements in a more agile way:

  • Reducing the cycles of development.
  • Can Deployment Frequency.
  • Automating and controlling the software development process from design, testing, release to implementation, and management.
  • Development streamlining and release network.

In this article, we will read about the best DevOps Tool and how to work for IT services:

What is Docker?

Docker is a system for container software technology, based on Linux containers.

The tool gives developers the freedom to apply and technology to build a virtual world to provide a forum for enhanced innovation.

The platform open-source is written in the Go programming language. It is lightweight in design because it does not need any hypervisor load.

The modular architecture enables Docker users to create cloud and on-premise applications.

The Docker Engine contains a daemon process (the docker command), a rest API to define the interfaces that programs use to communicate with the daemon, and a CLI client.

Because of standardization, developers can diagnose and repair software bugs more effectively, and also make improvements to the Docker files. Users can create a single image during deployment and use it every step of the way.

Docker’s client-server architecture allows the client to communicate with the daemon, which performs tasks such as constructing, running, and distributing the containers.

Pros of Docker:

  • Private environmental paas
  • Docker hub for the FTW
  • Package the environment with the application
  • macOS support FAKE
  • It’s unique
  • Easy to set up and implement
  • Isolation
  • Open-source
  • Testa­bil­i­ty and re­pro­ducibil­i­ty
  • Lightweight
  • Standardization
  • Designed
  • Models upgrading / downgrading / application
  • Security
  • Portability
  • Limit resource usage
  • Game changer
  • I love the way docker virtualization has improved
  • Fast
  • Concurrency
  • Docker’s Compose tools
  • Fast and Portable
  • Easy setup
  • It’s dope
  • Makes shipping very easy to production
  • Highly useful

Cons of Docker:

  • Twitter
  • Vox media
  • Robinhood
  • Pinterest
  • Spotify

What tools integrate with Docker?

  • Java
  • Bitbucket
  • Docker compose
  • Ansible
  • Kubernetes
  • Virtual Box
  • Vagrant

What is Kubernetes?

Kubernetes is an open-source Docker container orchestration platform. It handles planning on nodes in a compute cluster and actively manages workloads to ensure that the users declared intentions match their state.

Google’s open-source platform enables users to simplify deploying, managing, and scaling containerized applications.

Docker lets the developer simply build and run the program.

With the help of Kubernetes, DevOps teams can streamline containers within a cluster.

Compared to other DevOps software Kubernetes is a dynamic framework. But it lets users solve the problem quickly, and execute orders.

The Cloud Native Computing Foundation (CNCF) manages the Kubernetes.

The DevOps focus has now moved to write modular applications that can be easily distributed, deployed, and run anywhere.

Whereas Docker provided the first step to help developers create, ship, and run apps easily, Kubernetes has helped make a giant leap by helping DevOps run containers in a cluster, manage applications through containers and track them effectively as well.

It helps vendors to build systems using core Kubernetes technology as it is based on a modular core API.

Pros of Kubernetes:

  • Self-healing
  • Scalable
  • Supports autoscaling
  • Cheap
  • Cloud Agnostic
  • Everything of CaaS
  • Backed by Red Hat
  • Runs on azure
  • Golang
  • Easy setup
  • Expandable
  • Custom and extensibility
  • Reliable
  • Quick cloud setup
  • Leader of Container Ship
  • An environment of self-healing, rich metadata
  • No cloud platform lock-in
  • Promotes the maintenance of new/strong infrastructure
  • Open, solid, and stable
  • Simple and powerful
  • Backed by google
  • Scale services
  • Replication controller
  • Permission management

Cons of Kubernetes:

  • Steep learning curve
  • Weak application workflow
  • Orchestrates the only infrastructure

Which companies make use of Kubernetes?

  • Shopify
  • Google
  • Delivery Hero SE
  • Robinhood
  • Stack
  • Atoyle15

What tools integrate with Kubernetes?

  • Docker
  • Vagrant
  • Microsoft Azure
  • Google compute engine
  • Rancher
  • Google Kubernetes engine
  • Ansible

What is Ansible?

Ansible is an information management automation tool. The aims of Ansible are mainly those of simplicity and optimum ease of use.

Ansible is a strong DevOps tool that streamlines the processes of IT automation. It helps to end repetitive activities and allows for quick production cycles.

Ansible automates the specifications including the deployment of software, cloud provisioning, and container orchestration.

The difference between Ansible and other tools is that this is only used for the deployment of configurations. Ansible is considerably easier than other DevOps methods.

It is used as a server and platform for the management of configurations. Ansible is supported by Red Hat which allows users to monitor complex deployment and security management at multi-tier levels.

It can be used to make improvements to and reconfigure newly-deployed computers. Also, Ansible’s ecosystem is fantastic and comes with the ability to write custom apps.

It also provides them with communication tools so the team members can be updated with integrated alerts using email and Slack.

Pros of Ansible:

  • Very fast
  • Works on windows but not easily manageable
  • Combine hash to get the final setup close to hiera
  • Masterless
  • Well-documented
  • Debugging is simple
  • Superb configuration
  • Simple
  • Powerful
  • Simple to learn
  • Agentless
  • Flexible
  • Makes sense
  • Super powerful and scalable
  • Dynamic Inventory
  • Backed by Red Hat
  • Works with AWS
  • Easy to maintain
  • Multi-language
  • Cloud Oriented
  • Easy
  • Vagrant provisioner
  • Consistency

Cons of Ansible:

  • No Unchangeable Infrastructure
  • Doesn’t Run on Windows
  • Dangerous
  • Backward compatibility
  • Difficult to install

Which companies make use of Ansible?

  • Zalando

  • Zomato
  • Birdview
  • Flyeralarm GmbH

What tools integrate with Ansible?

  • Amazon EC2
  • New Relic
  • Microsoft Azure

As a result, Docker and Kubernetes are excellent application-deployment platforms. But they provide only a sliver of the flexibility operations teams need to be successful on their own. Fortunately, there are resources available in Docker and Kubernetes to fill any operational holes.

So we can show that How DevOps teams can use one of these tools, Ansible, to streamline their work while supporting environments based on Docker and Kubernetes. So, Ansible is the best DevOps tool.
