The docker manifest command does not work independently to perform any action. In order to work with the docker manifest or manifest list, we use sub-commands along with it. This manifest sub-command can enable us to interact with the image manifests. Furthermore, it also gives information about the OS and the architecture, that a particular image was built for. The image manifest provides a configuration and a set of layers for a container image. This is an experimenta
Following the second video about Docker basics, in this video, I explain Docker architecture and explain the different building blocks of the docker engine; docker client, API, Docker Daemon. I also explain what a docker registry is and I finish the video with a demo explaining and illustrating how to use Docker hub.
An image like the one we created in the Node.js Hello World Docker Container from scratch post is simple, yet it’s a perfect example to try one of the cool features of Docker, provided through Docker Hub, the official hosting service of public and private Docker Images. Before we can do that, however, we need to register on Docker Hub. Docker Hub is free in its basic plan which includes unlimited public repos and one private repo.
In a previous article, we explained the difference between Docker images and Docker containers. In short: An image is like a Java class, and containers are like Java objects. In this tutorial, we'll look at the various ways of removing Docker images.
Series Index Reducing Image Size Details Specific To Different Languages Going Farther To Reduce Image Size Introduction When getting started with containers, it’s pretty easy to be shocked by the size of the images that we build. We’re going to review a number of techniques to reduce image size, without sacrificing developers’ and ops’ convenience. In this first part, we will talk about multi-stage builds, because that’s where anyone should start if they want to reduce the size of their images.
