How to Install Docker on Windows, Mac, & Linux: A Step-By-Step Guide

Docker is intended to benefit developers and system managers and makes it a component of a number of toolchains for DevOps (developers + activities). This implies that designers can concentrate their attention on writing code without worrying about the scheme that it will eventually run on. It also gives them the opportunity to take advantage of one of the thousands of programs intended to operate as part of their implementation in a container at Docker. Docker offers flexibility for the operational team and decreases possibly a smaller overhead footprint and lower overhead the number of devices required.Let’s now deep dive into installation steps for docker on different platforms.Install Docker on Windows The community version of Docker for Microsoft Windows is Docker Desktop for Windows.Download from Docker Hub. System RequirementsThe software and hardware requirements need to operate Client Hyper-V on Windows 10 effectively are:Software Requirements:Windows-10 64-bit system requirements: Pro, Enterprise or EducationWindows characteristics of Hyper-V and Containers must be activatedHardware Requirements:The support for virtualization of hardware-level Client Hyper-V in BIOS settings must be allowed with the 64-bit processor with second-level address translation (SLAT). Minimum 4 GB RAMTo run Docker Desktop, Microsoft Hyper-V is needed. The Windows installer Docker Desktop allows Hyper-V and restarts your computer if needed. VirtualBox no longer operates when Hyper-V is activated. All VirtualBox VM images are however maintained.The DOCKer VMs (including the default one generated during the installation of the Toolbox) are no longer started. VirtualBox The Docker desktop can not use these VMs side-by-side. You can still handle remote VMs using the docker.What is included in Installation?The installation of Docker Desktop consists of the Docker Engine, Docker CLI, Docker Compose, Docker Machine, and Kitematic. Docker Desktop containers and images are shared among all user accounts on the machines where they are installed. All Windows accounts are building and running containers using the same VM. Nested virtualization situations, such as operating Docker Desktop with VMWare or Parallels, might operate. See Running Docker Desktop in nested situations for more data.Installation steps To run the installer, double-click Docker Desktop Installer.exe to install Docker Desktop on Windows. The installer can be accessed from Docker Hub if you have not previously downloaded (Docker Desktop Installer.exe). It typically downloads to your download directory or can be executed at the bottom of your internet browser from the latest download bar.Follow the installation wizard directions for licensing, authorizing the installer and proceeding with the installation. If advised, authorize your system password during the installation of the Docker Desktop Installer. The networking elements, connections to the applications of Docker and the management of Hyper-V VMs need to be privately accessible.Click Finish in the setup window and launch the application Docker Desktop.Start Docker DesktopAfter installation, Docker Desktop will not begin automatically. Search for Docker and select the search outcomes for Docker Desktop.If the whale icon remains stable in the status bar, Docker Desktop is up and running and can be accessed from any terminal window.You also get a pop-up message with the next steps, as well as a link to this documentation, after the Docker Desktop app is installed.When you're done initializing, click on the whale icon in the Notifications region and pick About Docker to check that your recent version is available.Install Docker on MacThe very first step is to download the Docker Toolbox for Mac. Get the downloadable link- Download from Docker HubSystem RequirementDocker Desktop for Mac starts only when all these requirements can be met:Mac hardware must be 2010 models or newer, including Extended Page Tables (EPT) and Unrestricted Mode, with Intel hardware to provide memory management unit (MMU) virtualization. This support can be checked to see if the following command is being run on your computer: sysctl kern.hv_supportmacOS Sierra 10.12 and newer versions of macOS are endorsed. The upgrade to the newest version of macOS is recommended.VirtualBox (incompatible with Docker Desktop on Mac) before version 4.3.30 must not be installed. It's alright if you have a newer VirtualBox version installed.Installation stepsDouble-click Docker.dmg and drag the whale Moby to the application folder to open the installer.In the Applications directory, double-click Docker.app to launch Docker. In the instance below, the applications folder is in the Grid view modeYou are led to allow Docker.app with your system password after starting it. Privileged access is required to install Docker app connections and networking elements.The whale in the top status bar shows that Docker runs from a terminal and is available.You will also get a success message, with the next steps and a link to this documentation, if you have just installed the app. To reject this pop-up, click on the whale in the status bar.To get Preferences and other options, click on the whale (whale menu).To check that you have the latest version, select About Docker.Notes:Getting started provides an overview of Docker Desktop for Mac, basic Docker command examples, how to get help or give feedback, and links to all topics in the Docker Desktop for Mac guide.Troubleshooting describes common problems, workarounds, how to run and submit diagnostics, and submit issues.Install Docker on LinuxLet’s use a Ubuntu example to begin installing Docker. If you don't already have it, you can use Oracle Virtual Box to install a virtual Linux example. A straightforward Ubuntu server mounted on the Oracle Virtual Box is shown in the following screenshot. There is an OS user called a demo defined with full root access to the scheme:Step 1 − We must first make sure you have the correct version of the Linux kernel running before installing Docker. Only version 3.8 or greater is intended for Docker on Linux kernel. We can do this with the instructions below.Uname: The system data for the Linux system is returned by this method. This method will return the kernel name, kernel release, kernel version information on the Linux system.uname -aa − Used for ensuring the return of the system data.Step 2 − You need to install packages from the internet onto the Linux system via the following command, the recent packages can be updated to the OS.apt-get Optionssudo− The sudo command is used to make sure the command runs with root access.update− Update option ensures that all packages on the Linux system are updated.sudo apt-get update Step 3- The next step is to install the certificates needed to later download required Docker packages for a job with the Docker site. The following command can be used.sudo apt-get install apt-transport-https ca-certificates Step 4− Adding fresh GPG key will be the next step. This key must guarantee that the required packages for Docker are all encrypted.This command is intended to download the key from hkp:/ha.pool.sks-keyservers.net:80 and add it to the adv keychain by means of the ID58118E89F3A912897C070ADBF76221572C52609D. Please note that to download the necessary Docker packages, this specific key is needed.Step 5 − Next, you need to add the appropriate site to docker.list of the apt package manager, depending on the version of Ubuntu which you hold, to allow it to detect and download the Docker packages from the Docker site.Precise 12.04 (LTS) ─ deb https://apt.dockerproject.org/repoubuntu-precise mainTrusty 14.04 (LTS) ─ deb https://apt.dockerproject.org/repo/ ubuntu-trusty mainWily 15.10 ─ deb https://apt.dockerproject.org/repo ubuntu-wily mainXenial 16.04 (LTS) - https://apt.dockerproject.org/repo ubuntu-xenial mainecho "deb https://apt.dockerproject.org/repo ubuntu-trusty main”     | sudo tee /etc/apt/sources.list.d/docker.listStep 6 –The next step is to update the packages on Ubuntu scheme with the apt-get update command.Step 7 ‐ if we want to make sure that the package manager points towards the correct repository then we can do this by issuing the apt-cache command.apt-cache policy docker-engineStep 8– Edit the update command apt-get to guarantee that all local system packages are up-to-date.Step 9- The Linux-image-extra-* kernel packages that allow the user to use the aufs storage driver are required for Ubuntu Trusty, Wily and Xenial.

11 Top Features of Docker That You Must Know

Docker is an open platform to develop, ship and run applications containers on a common operating system. It enables you to separate applications from infrastructures so that software is delivered quickly. Infrastructure can be managed by Docker in the same way as one managed their applications. The delay between writing code and running it for production can be significantly reduced with the help of Docker’s methodologies for quick shipping, testing, and deployment of codes. Features of Docker:Docker provides various features, some of which are listed and discussed below.Faster and easier configurationApplication isolationIncrease in productivitySwarm Services Routing Mesh Security Management Rapid scaling of Systems Better Software Delivery Software-defined networkingHas the Ability to Reduce the Size1. Faster and Easier configuration: It is one of the key features of Docker that helps you in configuring the system in a faster and easier manner. Due to this feature, codes can be deployed in less time and with fewer efforts. The infrastructure is not linked with the environment of the application as Docker is used with a wide variety of environments. 2. Application isolation:Docker provides containers that are used to run applications in an isolated environment. Since each container is independent, Docker can execute any kind of application. 3. Increase in productivity:It helps in increasing productivity by easing up the technical configuration and rapidly deploying applications. Moreover, it not only provides an isolated environment to execute applications, but it reduces the resources as well.4. Swarm: Swarm is a clustering and scheduling tool for Docker containers. At the front end, it uses the Docker API, which helps us to use various tools to control it.  It is a self-organizing group of engines that enables pluggable backends.5. Services: Services is a list of tasks that specifies the state of a container inside a cluster. Each task in the Services lists one instance of a container that should be running, while Swarm schedules them across the nodes. 7. Security Management: It saves secrets into the swarm and chooses to give services access to certain secrets, including a few important commands to the engine such as secret inspect, secret create, etc.8. Rapid scaling of Systems: Containers require less computing hardware and get more work done. They allow data centre operators to cram more workload into less hardware, meaning sharing of hardware, resulting in lower costs. 9. Better Software Delivery: Software Delivery with the help of containers is said to be more efficient. Containers are portable, self-contained and include an isolated disk volume. This isolated volume goes along with the container as it develops and is deployed to various environments. 10. Software-defined networking:Docker supports Software-defined networking. Without having touched a single router, the Docker CLI and Engine enables operators to define isolated networks for containers. Operators and Developers design systems with complex network topologies, as well as define the networks in configuration files. Since the application’s containers can run in an isolated virtual network, with controlled ingress and egress path, it acts as a security benefit as well.11. Has the Ability to Reduce the Size:Since it provides a smaller footprint of the OS via containers, Docker holds the capability to reduce the size of the development. Who is Docker for?Docker as a tool benefits both developers and system administrators, and hence is a part of various toolchains of DevOps (Developers+Operations). It helps developers to focus on writing the code and not worry about the system that it will run on. Moreover, they can make use of one of the thousands of programs that are already designed to run in a Docker container as a part of their applications and get a head start. As for Operations, Docker provides flexibility as well as reduces the number of systems needed due to its lower overhead and small footprint. To Sum Up…We have discussed the top 11 Docker Features that help it stand out from the crowd and gives it huge popularity. It is popular due to its revolutionized development in the software industry, creating vast economies of scale. Hence, containers and Dockers hold the potential to open up new opportunities for your enterprise.

8 Key Challenges Of Implementing DevOps And Overcoming Them

The increase in the number of companies to adopt DevOps to improve their workflow and productivity has led to an increase in the recurring concerns regarding its implementation. The answers to questions such as ‘Where and how do I start with my DevOps adoption?’, ‘What are the challenges that I might face?’ and ‘How do I go about to resolve those challenges?’, are very commonly sought after. Bringing about such a revolutionary change from the traditional Waterfall approach to DevOps is not an easy process. The following lists some of the major challenges that organisations face while implementing DevOps.Change in Culture: The workplace culture undergoes the major amount of transformation while implementing DevOps. It is also one of the most difficult areas of transformation as it is a long term process which also requires a lot of patience and endurance. To make the process a bit easier, enterprises should try and maintain a positive as well as a transparent atmosphere in the workplace. Switching from Legacy Infrastructure to Microservices: In order to reduce stability issues, organisations now use infrastructure as code along with microservices for quicker development along with sharp innovations. Moreover, organisations need to update their hardware and software systems according to the latest trends on a regular basis, so that new systems can co-exist with the existing systems. Issues with the standards and metrics: Dev and Ops departments have different goals and working systems, hence they have different toolsets as well. It might become very tedious to sit together and integrate the tools. Under such circumstances, it is advisable that the teams agree upon a commonly decided metric system.Tool Turbulence: Switching to DevOps practices might make people dependent on the various tools that are available to solve even the smallest of their problems.  Due to this, organisations might become addicted to those tools which provide with short-term benefits over the ones which provide with long-term benefits. Some of the tools are open-sourced or SaaS-based and can be easily adopted without any authorization. To make things easier, you can provide teams with a set of library tools from which they can opt for their preferred tools. This will also help the leaders stay up-to-date with the activities of the employees. Resistance to Change: You might come across people in your company who might not be supportive of the legacy systems. They are the ones who have become comfortable with their way of working and are not willing to leave their comfort zones. Hence, it is very important that you don’t bend down to such elements but instead bear with the discomfort of change. Challenges during the process: Adopting DevOps can prove to be challenging for workers who blindly follow guidelines and stay stuck to the rules, or for companies which follow specific guidelines for software development, as DevOps doesn’t have any fixed framework stating procedures that employees can follow to reach their desired goals.The teams can decide on their own course of action without any structural approach, giving them opportunities and more scope for innovation. Test Automation: Test Automation holds equal importance as CI/CD deployments. It has been commonly observed that companies tend to neglect test automation and focus more on CI/CD deployments. For DevOps to be a success, continuous testing acts as a key. Cost and Budget: It is very important to keep in mind that open source does not necessarily mean that it is free of cost. Moreover, factor in integration and operational complexity to your overall costs. In a Nutshell:As Heraclitus, a Greek philosopher says that change is the only constant. It might be hard in the beginning, messy during the process, but it is always glorious in the end. Evolving in the IT culture, DevOps brings you closer to bridge the boundary between business, development and operations. Overcoming these challenges from the root will make the transition process smoother for you.

Top 10 DevOps Programming Languages That You Must Know

DevOps movement tries to eliminate the gap between software development and IT operations. Programming languages act as one of the most important tools in DevOps. To be successful in DeOps and achieve Continuous Integration/Continuous Delivery (CI/CD), making the right choice of a programming language is very essential. Below discussed are the top 10 DevOps programming languages that you can opt for to become a successful DevOps engineer. Ruby: Even though it is considered to be higher-level programming, it is much easier to learn Ruby when learning to code. The top use case of Ruby is its infrastructure management and is very similar to Python. It provides a flexible approach to programming as the developers can make alterations in parts of the language to fit the requirements. Moreover, it allows you to manipulate frameworks and controllers. Hence, it is a very powerful language.Many infrastructure projects utilise Ruby, like ManageIQ is a Ruby on Rails app.  C/C++: Even though different programming trends have come and gone and continue to do so, C has remained as one of the most popular programming languages for more than half a century. C/C++ offers multiple benefits like fast and high performance and acts as a foundation for modern computing. Moreover, C is such a language that most programmers already know (to some extent).  However, C/C++ have drawbacks while working in a DevOps environment. Its size is greater in magnitude when compared to languages like Go or Ruby. As a consequence, the compilation time is also greater in C/C++. Also, the application binaries produced by C are not portable.  Hence, DevOps has a lesser friendly approach to using C/C++.Python: Python is a scripting language that is very useful for managing infrastructure. With a wide range of usage, it is used to build cloud-based infrastructure projects like OpenStack, while it also supports web applications through frameworks like Django. It is even considered as the most popular language for machine learning.When it comes to DevOps, Python helps reduce maintenance problems with the help of monitoring and deployment tools like Salt, Ansible, etc.  JavaScript: JavaScript is a lightweight, interpreted programming language, which allows you to build interactive websites. Nowadays, it is also being used in mobile app development, desktop app development and game development. There are many popular frameworks and libraries written in JavaScript, such as React, Node, etc.JavaScript might get a bit complicated for DevOps, but that doesn’t mean that they don’t tag along well. On the brighter side, it offers less interaction, immediate feedback along with better interfaces as compared to other languages.Go: Due to the fact that Go made its debut in 2009, near about the time when DevOps was hitting the market, DevOps and Go have tended to grow together, side by in various respects. Built on the foundation of C, it emphasises more on lean, network=efficient runtime, which acts as an advantage for DevOps.Go is an amazing choice of programming language for DevOps as it offers excellent performance. It takes care of concurrency and is highly portable. Also, there isn’t any need for creating dependencies when compiling Go applications and can be built quickly.SQL: Structured Query Language (SQL) is a computer language which stores, manipulates and queries data in relational databases.SQL is used in DevOps due to its container support. SQL Server 2017 supports Linux OS and its containers run on Windows, Linux and macOS.Bash: Bash is one of the most frequently used Unix Shell and carries a lot of support. Bash’s Shell and scripting language powers thousands of Linux systems around the world. Moreover, it is available for Windows and Mac too.Perl: Perl is a stable, cross-platform programming language which belongs to a family of high-level, general-purpose, dynamic programming language. It is used for simple as well as complex tasks, for small or major projects. Perl provides a quick fix solution for web apps, text processing, GUI development, etc.Since DevOps is a combination of Software Development and IT Operations, Perl is used more on the application development side.Java: Java is an object-oriented, class-based and general-purpose programming language. It is ideal for jobs which are concurrent in nature and requires its implementation dependencies to be reduced. It is widely used due to its versatility and power.PHP: PHP is a general-purpose programming language which is used all over the world. PHP covers the internal system right from its early stages up to its implementation.PHP is perfect to be utilized by your DevOps if you wish to use a programming language for non-specific coding.To Conclude:It is never too late for a Developer to learn new and different programming languages. Due to the advancement in the technology in automation and operation, you can always opt to work and sharpen new skills and programming languages.

How much does a Scrum Master earn? How prolific being a Scrum Master is? These are quite relatively simple and common questions but answering them is not that simple.

Morgan91,786Capital One87,732AT&T85,977In the past few years, the pay structure for Scrum Masters has increased at a relatively quick pace. Although Scrum’s popularity status continues to get better, being a Scrum Master is undoubtedly a tough task because what a Scrum Master needs is more like servant leadership skills, and that is the primary asset a Scrum Master needs to possess. After all, it is all about following the Agile-Scrum tactics to finish projects on time along with keeping the quality of the end product intact.Factors affecting a Scrum Master’s salaryThere are many factors that determine how much a Scrum Master earns. Some of the key ones are:1. ExperienceThis is one of the most important criteria, if not the most important one. Like discussed in the previous section of this article, not only the salary of a Scrum Master increases with experience, the job role and position in an organisation gets better as well. Here are a few of the required skills/experience:In terms of landing a better Scrum master job with high pay package, it is recommended for a professional to have worked as a Scrum Master for a minimum of one year with a software development team, one that was diligently applying Scrum principles, practices, and theoryAdequate skills in and understanding of servant leadership, facilitation, situational awareness, conflict resolution, continual improvement, empowerment, and increasing transparency.2. The skills required by the job roleAnother important one. A Scrum Master’s role is not restricted to particular job designation. The more you know about the other Agile approaches in problem-solving, the better your job role and salary will be. By Agile approaches, we are talking about XP, Kanban, Crystal, FDD, etc3. Awareness of multiple Agile techniquesTo get better job opportunities, it is preferred to have knowledge of widely successful Agile techniques such as:User StoriesATDDTDDContinuous IntegrationContinuous testingPairingAutomated TestingAgile Games4. Applicable knowledge of the technologiesA particular organisation will pay you a better package for a Scrum Master if you have a sound grip over the type of technology they use to run their business. Why? It is simple. If you are aware of the system they work in, then they do not have to work on much in getting you in sync with the way they work in their organisation5. Knowledge of appropriate patterns and techniquesA progressive Scrum Master always thinks of using a variety of relevant well-documented patterns and techniques for filling in the intentional gaps left in the Scrum approach, such as Burndown technologies, various Retrospective formats, handling bugs and many more6. Location of the jobThe salary of a Scrum Master depends massively on where the job posting is. If the living standard of a particular city is high, so are the chances of getting a higher pay package. On the other hand, a city having a comparatively lower standard of living renders the Scrum Masters with a lesser salary range.Reason for Scrum Masters being so valuedWhy are the Scrum Masters paid so much? What do the Scrum Masters have to offer that makes them so vital to organisations? After all, in the past few years, Scrum methods have swiftly brought in a revolutionary change in project handling and problem-solving matters.We are living in times when software needs to be delivered on time after much feedback, changes, supervision. Collaboration with frequent updates and patches. To meet the delivery deadline, it is essential to keep the team members connected and in sync, preferably face-to-face. This is critical as the team working on the project should be well informed, collaborated and kept up to date throughout the project. Failure to execute any one of these steps would lead to a breakdown in software, the end result being loss of business, not to forget the reputation of the relevant organisation being tarnished.Nowadays, companies prefer the Agile workflow and are aware of the importance of a Scrum Master in an organisation. Converting a team into a productive one and self-organised by following the Agile practices without any fail, that’s what Scrum Masters do and that is what makes them special.
