Since the emergence of DevOps, there had been a lot of buzz around it as DevOps is a combination of tools, framework, and automation. DevOps aimed to align the Dev and Ops team with shared goals. DevOps practices are applied to other teams as well. For more information about the DevOps training and certification, refer DevOps tools courses
DevOps is a mindset, not a toolset. But nothing could workout in an IT team without proper tools. DevOps teams use tools to accelerate and automate the process, thereby ensuring continuous integration, continuous delivery and automation.
The need for DevOps can be understood by the following example. A developer builds an application and sends it to the tester. But, the environments of development and testing systems are different; thus, the code does not work. There are two solutions to this: Docker and Virtual Machines, but Docker is far better in terms of performance, scaling, and efficiency.
DevOps teams could also get benefit from emerging technologies like AI/ML. The AI/ML teams can create patterns for DevOps teams so that the DevOps team can leverage the opportunity to find coding problems that cause bugs so that the DevOps teams can dig deeper into it.
CI/CD is an essential part of DevOps, it maximizes the development phase thereby reducing the time and effort in integrating, testing and deploying the components. The CI/CD practice shifts the focus of the team on to development thereby increasing the organization productivity, efficiency, testing and collaboration.
In some of the DevOps models, security teams get aligned with development and operations and throughout the application lifecycle to ensure that the development meets all the compliance requirements from the beginning of the application itself. When there is a focus on security in the DevOps team, then it is referred to as DevSecOps.
DevSecOps can be applied to any environment such as cloud native, on premises, hybrid etc.
Docker is a platform that enables creating, deploying, and running applications with the help of containers. A container is a unit of software that packages the code and all its dependencies together such that the application becomes runnable irrespective of the environment.
Container isolates their application and its dependencies into a self-contained unit that can run anywhere. Container removes the need for physical hardware allowing for more efficient use of computing resources. They provide operating-system-level virtualization. Moreover, developers can collaborate faster without worrying about which software dependency they need to install.
A container is a runnable instance of an image. An image is a read-only template with instructions for creating a Docker container. To get more knowledge on docker refer to Kubernetes and docker certification.
Docker is an open source software platform to create, deploy and manage virtualized application containers on a common operating system. Docker packages, provisions and runs containers. Docker packages the application with its all necessary configuration files, dependencies .Each container shares the common underlying Operating system. Software Developers can create containers without docker, but docker makes it more easier to build, safer and simpler to build and deploy containers.
Docker enables
It consists of a Docker Engine which is a client-server application with three major components:
1. After downloading Docker Desktop Installer.exe, run the following command in a terminal to install Docker Desktop
"Docker Desktop Installer.exe" install
2. If you’re using PowerShell you should run it as
Start-Process '.\win\build\Docker Desktop Installer.exe' -Wait install
3. If using the Windows Command Prompt
start /w "" "Docker Desktop Installer.exe" install
4. Docker desktop doesn't start automatically after installation. Search for Docker Desktop in windows and select
Before starting the application, Docker offers an onboarding tutorial. The tutorial explains how to build a Docker image and run a container.
Here is a list of elements you should have in order to create and run Docker containers:
To start docker in daemon mode, navigate to docker file location where the docker desktop app is installed and run the dockerd.exe
Sometimes there might be an issue with docker like docker daemon not starting, in order to resolve the issue, one can try the following resolution.
Resolution 1: Restart the docker service, Go to start→search→services.msc. From the services, screen click on Docker Desktop services→restart.
Resolution 2: Using DockerCli.exe, one can switch daemon configuration. One can use the below command to point the docker CLI to either linux or windows.
From powershell,
PS C:\Program Files\Docker\Docker> ./DockerCli.exe -SwitchDaemon
Resolution 3: Restart the docker services using GUI. From the docker GUI, Settings -> Reset – Restart Docker Desktop.
By enabling the wsl2 engine for docker, it enables user to leverage Linux workspaces and users to avoid maintaining both Linux and window build scripts. This enables the docker windows container on Linux.
From the Windows desktop menu, you can select which daemon the docker CLI talks to. One can select ‘Switch to window containers’ to use window containers and select ‘Switch to Linux containers’ to use Linux containers.
To uninstall Docker Desktop from your Windows machine
Installing the docker on windows can be done by following the above-mentioned steps. One can use docker CLI windows to start, stop and configure the containers. Above are mentioned steps to install docker on windows. For more information refer to docker classes.
Yes, docker can run on windows 10. Docker can run on Windows 10/10 pro and Windows 11/11 pro. For details about the system specifications, refer to docker specifications.
Once the Docker is installed using the docker installer, go to windows start and search for Docker Desktop. Start the Docker Desktop application.
Docker Desktop is licensed as part of a free (Personal) or paid Docker subscription (Pro, Team, or Business).Depending on the usage one can obtain the subscription.
No, Windows containers cannot run on Linux. Since the containers use the underlying Operating system, resources and drivers. Hence Window containers should run on Windows Operating system and Linux Containers should run on Linux operating systems.
