      Docker really did change the world

      pubsub.slavino.sk / infoworldcom · Tuesday, 16 November, 2021 - 11:00 edit

    In 2013, Docker was the “it” company. Docker made headlines for the critical role it played in bringing containers to the mainstream, and in many ways displaced PaaS as the hotness of the time ( Heroku anyone ?). Now, the company is back in the press with the introduction of a new model for Docker Desktop that requires larger organizations to buy a paid subscription for the tools. There’s been a vocal reaction to this announcement , one that reminds me of the important role Docker played in popularizing a model we know, love, and now use on a mainstream basis: containers.

      How to use Docker for Java development

      pubsub.slavino.sk / infoworldcom · Thursday, 4 November, 2021 - 10:00 edit

    The promise of using Docker during development is to deliver a consistent environment for testing across developer machines and the various environments (like QA and production) in use. The difficulty is that Docker containers introduce an extra layer of abstraction that developers must manage during coding.

    Docker enables application code to be bundled with its system requirements definition in a cross-platform, runnable package. This is a graceful abstraction for solving a fundamental need in deploying and managing software runtimes, but it introduces an extra layer of indirection that must be dealt with when programmers are doing what they do: iteratively modifying and testing the internals of the software and its dependencies.

      Installing Additional Modules in the Icinga Web 2 Docker Container

      pubsub.slavino.sk / icinga · Wednesday, 20 October, 2021 - 09:21 edit

    The Docker images we provide for both Icinga 2 and Icinga Web 2 already contain quite a number of modules. For example, the Icinga Web 2 image contains all the Web modules developed by us. But one of the main benefits of Icinga is extensibility, so you might want to use more than what is […]

      What is Docker? The spark for the container revolution

      pubsub.slavino.sk / infoworldcom · Monday, 2 August, 2021 - 10:00 edit

    Docker is a software platform for building applications based on containers —small and lightweight execution environments that make shared use of the operating system kernel but otherwise run in isolation from one another. While containers have been used in Linux and Unix systems for some time, Docker, an open source project launched in 2013, helped popularize the technology by making it easier than ever for developers to package their software to “build once and run anywhere.”

    A brief history of Docker

    Founded as DotCloud in 2008 by Solomon Hykes in Paris, what we now know as Docker started out as a platform as a service (PaaS) before pivoting in 2013 to focus on democratizing the underlying software containers its platform was running on.
