Docker is an open platform for developing, shipping, and running applications. Docker enables you to separate your applications from your infrastructure so you can deliver software quickly. With Docker, you can manage your infrastructure in the same ways you manage your applications. By taking advantage of Docker’s methodologies for shipping, testing, and deploying code quickly, you can significantly reduce the delay between writing code and running it in production.
There are several courses available on Docker topic. Some of them are very short and do not serve any other purpose than a ‘Getting started course’, while others are super long and require you to spend several days to study and understand everything. My aim with this tutorial is hit a balance between conciseness and exhaustiveness.
You can install Docker on Windows, Ubuntu, and mac with quite easy steps. Docker is an open-source tool designed to make it easier to create, deploy, and run applications by using containers. Docker is the best container orchestration tool and most of the big companies now using docker to deploy applications. This blog post covers Basic Overview for how to install docker i.e different Docker Edition, how to practice docker.
In order to do something useful with containers, they need to be organized as a part of a project, usually referred to as an application. There are multiple ways of orchestrating a Docker application, but Docker Compose is perhaps the most human-friendly. It is a tool for defining and running multi-container Docker applications. It allows users to launch, execute, communicate and shut containers with one coordinated command. It makes it easier for users to orchestrate the processes of Docker containers, including starting up, shutting down, and setting up intra-container linking and volumes.
A couple of decades ago, if I was to say that “I can run my application using a ~10 MB file“, people would have called me crazy and would have denied it outright. Fast-forward to 2020, almost everyone wants to learn about Docker vs Virtual Machine (VM). The invention of VMs was a huge boost to our computing powers, just because we could run many instances of different operating systems using the same hardware/servers. So, I have decided to shed some light on Container vs VM and explain the differences too.
Docker is a containerization platform for developing, shipping, and running applications inside containers. We can deploy many containers simultaneously on a given host. Containers are very fast and boot up quickly because they don’t need the extra load of a hypervisor in comparison to the virtual machines because they run directly within the host machine’s kernel. In this blog, we will talk about Docker Container Lifecycle Management.
Docker simplifies and accelerates our workflow while giving developers the liberty to innovate with their choice of tools, application stacks, and deployment environments for every project. Docker uses storage drivers to manage the contents of the image layers and the writable container layer. In this blog, I’ve covered everything about Docker Storage. There are many places inside Docker (both at the engine level and container level) that use or work with storage.
Docker is a tool designed to make it easier to create, deploy, and run applications by using containers. In this blog, I’ve covered an introduction to Docker Network. It allows you to attach a container to as many networks as you like. You can also attach an already running container.
Docker containerization seems to be the perfect strategy to deploy your application. But is it really flawless? Well, it all depends on how you build the strategy to deploy an application. The Container Images do have their vulnerabilities and possess a security threat. We will have a look at these factors and also about a tool called Trivy to Scan a Docker image in detail.
According to Moore’s law, the computer processing speed supposedly doubles every 18 months or so! Docker is undoubtedly on edge out of all application deployment strategies in today’s world. Consequently, most IT professionals are looking to learn Docker. Well, if you are looking for one, you are in for a treat! To summarise, this post is a complete course with a Hands-on tutorial from beginner to advanced level.
Docker Images are the starting point for anyone who is new in the Docker world. They are used for launching the Docker Containers. It is a unit of packaging that contains everything required for an application to run.
