We at Practical DevSecOps rely on docker to deploy various SCA, SAST, DAST, and monitoring tools for our clients. This division helps you switch, a part of the stack with any other alternative Docker for DevOps Lessons and removes the dependency on one vendor (bye-bye vendor lock-in). For example, runC runtime can be replaced with CRI-O while still using dockerd and containerd from Docker.
Now run docker images to see our list of images again, you should see apacheimage in the list. Notice we don’t see the container that we created listed, the reason is because we exited bash, and since that’s the only thing the container was running, the container automatically stopped. Go ahead and run docker ps –a to see all containers, including those that have stopped.
Streaming Now: Docker Advanced
You could be a web developer, sysadmin, operations manager, or part of an IT / testing / QA team. Don’t waste your valuable time piecing together disconnected tutorials from different sources. Enroll now and gain the skills and knowledge you need to excel, all in one place.
By bridging the gap between development and operations, Docker accelerates development cycles and enhances scalability and flexibility in microservices-based architectures and cloud deployments. As the demand for efficient and reliable DevOps tools grows, Docker’s role in shaping modern software development practices becomes increasingly pivotal. Docker is an open platform that enables users to develop, ship, and run applications with ease. Docker software is packaged as containers- a docker standardized unit. These containers have all the elements, such as system tools, libraries, runtime, etc required by the software. In this lesson, you will learn all the basics of Docker and how to set it up along with a guide on choosing the right plan as per your needs.
Learn by Doing. Just Enough Theory, Combined with Tons of Real Examples
I have been working on a Flask project running on Docker for months and until now had very little knowledge of how things actually fit together in Docker. This course was flawless in explaining every segment in detail while keeping it easy to follow along and learn. I’ve taken a few courses with Nick and the reason I keep coming back is his passion for software development, his desire to share his knowledge with others, and his strong ability to do so.
Are you feeling stuck or overwhelmed in your coding journey? Together, we’ll work to level up your skills, increase your earning potential, and build a brighter future. Tired of piecing together disconnected tutorials or dealing with rambling, confusing instructors? It’s perfectly structured into a series of bite-sized, easy-to-follow videos that cover both theory and practice. You can think of a Docker image as a class in object-oriented programming, and a Docker container as an instance of that class.
Docker/Container Disadvantages
You don’t need to spin up your own servers or even install Linux yourself. We don’t have to monetize all 17 million to have a fantastic business… Interview As the IT industry faces an inflection point thanks to AI, lessons can be learned from Docker in how a company can – or must – pivot in the face of a changing reality. If you’re planning to attend a software engineering interview for a job role that requires you to have a good understanding of Docker, this lesson will be extremely useful.
Docker makes it easy to deal with multiple active versions of your favorite language, and getting things running in production becomes a breeze because your app gets built into shiny self contained packages. All you have to do is move them from one environment to the next and you’re good to go. The best answer you can get from your developers is “it works for me!”, and now you’re stuck having to assimilate yourself into the ecosystem of whatever stack your developers used for the project.
This way you don’t really need to have your own environment set up to get some hands-on practice. The coding exercises will validate your commands and Dockerfiles and ensure you have written them correctly. Docker’s approach to containerization has streamlined collaboration between developers and IT operations teams, making it a cornerstone for continuous integration and deployment (CI/CD) pipelines.
