Since I got into programming, I’ve regularly seen operating-systems tutorials and implementation guides pass by. They always leave a lingering desire behind them, an echo of the well-known siren song: “when are you going to create your toy operating system?” Inevitably, time passes and the desire fades, till the next tutorial shows up and the cycle repeats. Today I’m breaking the cycle. I’m setting a challenge for myself, and I’m publishing it for the sake of the many curious soul...| Adolfo Ochagavía

When Bash starts, it loads a bunch of startup scripts to configure itself. You know, ~/.bashrc and friends. Which scripts are executed in what order is complicated. It depends on the type of the shell, the mode it’s in, how it was compiled, and what code each Linux distribution puts into the default startup scripts. The type of shell has two components: An interactive shell is what most people think of as the command line. It shows a prompt, waits for keyboard input and prints output to a s...| Here Be Braces

At the Linux Application Summit (LAS) in April, Sebastian Wick said that, by many metrics, Flatpak is doing great. The Flatpak application-packaging format is popular with upstream developers, and with many users.

You’ll use the Docker command l...| Play with Docker classroom
In the previous exercise you pulled down images from Docker Store to run in your containers. Then you ran multiple instances and noted how each instance was isolated from the others. We hinted that this is used in many production IT environments every day but obviously we need a few more tools in our belt to get to the point where Docker can become a true time & money saver. First thing you may want to do is figure out how to create our own images. While there are over 700K images on Docker S...| Play with Docker classroom

So far we have explored using single instances of containers running on a single host, much like a developer might do when working on a single service application or like an IT adminstrator might do on a test rig. Production applications are usually much more complex and this single server model will not work to coordinate 10s or 100s of containers and the network connections amongst them, not to mention the need to ensure availability and the ability to scale.

This lab is longer than the other ones. It features a demo app built around a microservices architecture, defined through a Compose file. You will run this app on a single node. Then, to scale that app on a cluster, you will learn the concepts powering SwarmKit, Docker’s native orchestration system. Armed with this new knowledge, you will setup your own Swarm cluster across five nodes, and use it to deploy the demo app. We recommend that you open two tabs or two windows for that lab: one fo...| Play with Docker classroom
This lab is longer than the other ones. It is designed to follow the part 1 (“from Compose to Swarm”) but can also be done independently (it provides jump-start instructions if you want to skip part 1).

You will also see how to implement logging, metrics, and will given a galore of tips and tricks to operate Swarm.

Introduction A registry is a service for storing and accessing Docker images. Docker Hub and Docker Store are the best-known hosted registries, which you can use to store public and private images.
