Completing a Docker course is one of the fastest, easiest ways to improve your career in DevOps. Docker is an industry-standard platform for containerization that is used across many industries. For developers who want to build, manage, and distribute containers in any environment, Docker is essential.

• Containers are lightweight and start almost instantly, allowing for quick scaling and deployment of services.
• Docker’s containerization model offers seamless portability across various infrastructure environments, from on-premises data centers to public and private clouds.
• They are created through a process called Docker build that uses a text file, called a Dockerfile, as input.
• It guarantees that if a feature functions in the development environment, it will also work in the production and staging environments.
• Multiple development environments can get created with unique software, configuration, and operating systems from the same host.

As you can see, if taking things to production is difficult, dev and ops are unaligned. The goal of Dev team is to take as many new features to production as possible. I see Agile and DevOps as two phases that helped us improve how we build great software. They don’t compete against each other, but together they help us build amazing software products.

A curated list of free Docker courses for developers and DevOps professionals

So, businesses are using DevOps, and for that, they are using DevOps Docker to test the application in a safe and secure environment. So, this is just an excellent way to deliver some applications. The Docker tool was designed for developers and system administrators, an essential part of DevOps. With Docker, developers can focus on application development rather than being worried about the platform where it will run.

Leran more about the right career path and certifications in our next section. Initially, companies used to run Docker Development and a non-Docker project first. Docker was used for development on small projects, and gradually it was adopted in bigger ones. Companies are progressively moving towards the complete adoption of Docker.

Role of Docker and Kubernetes in DevOps

There are many startups that are slowly adapting the docker technology because of the above-mentioned benefits. With docker, we can containerize the application with the required environment (os, libraries) and ship the application. Since it’s containerized into a single package, it won’t cause dependency collision issues. So before you learn how to attack containers, you need to understand a few things about containers. Kubernetes adds on to this by helping to orchestrate different types of containers and deploying them to clusters. Using Docker, you can build images of microservices — irrespective of their language.

This laser-focused course is based on creating Docker images and using Docker swarm for Java-based cloud-scale computing. In the Docker Deep Dive, developers go from no knowledge Docker for DevOps Lessons of Docker to knowing absolutely everything they need to know. Intended for intermediate users, this course digs deep into Docker usage in real-world scenarios.

Top Kubernetes courses:

The layers of a Docker image are stored in the Docker engine’s cache, which ensures the efficient creation of Docker images. But Docker made everything easier with a rather simple approach. Not to say that it was simple for the developers to write this utility.

• But Docker can easily help to replicate the file to the new hardware.
• APIs revolutionize the way we connect different systems and applications.
• If you’re interested in expanding your skills with DevOps, the time is right.
