A Quick Look at LinuxKit Packaging System

One of the most compelling feature of LinuxKit is “Everything replaceable and customisable”. You can now build up your own customised Linux Operating System so as to run it across various platforms like Bare Metal Hardware, Virtual Machines, Cloud Instances etc. As of today, LinuxKit supports various platform like OSX/Hypervisor, Google Cloud Platform, Packets.net, QEMU/KVM &  VMware ESXi vCenter Server. Effort has already been started for enabling this solution on AWS, Azure, Bluemix etc. For Raspberry Pi aspirants, there is already a feature request raised for enabling LinuxKit on ARM64 platform. LinuxKit is built with containers to run the containers. It...

Demystifying the Relationship Between Moby & Docker

Why https://github.com/docker/docker been redirected to moby/moby?  Why Docker created the Moby project? Is Docker renamed to Moby? What it actually mean when we say Moby is going to be upstream project? – I have been reading a lot of such queries in twitter and open forums even after dozens of blogs are available to clarify the confusion. Still confused about the relationship between Moby  and Docker? –  Under this blog, I will try to clarify the relationship between “the Moby project” & “Docker product” through popular existing analogy -Fedora, RHEL & CentOS.                ...

Test-Drive LinuxKit OS on Oracle VirtualBox running on macOS Sierra

In my last blog post, I showed how to get started with LinuxKit for Google Cloud Platform. LinuxKit is secure, lean and portable Linux Subsystem for the container movement and it is being built for various platforms which Docker runs on, for example – Azure, VMware ESXi, AWS and bare metal system. It went open source just 10 days back and you can see that the project has received over 2300+ stars in just 1 week time. That’s really appreciating figure. If you are completely new to LinuxKit, please refer my last blog post for understanding its basic concept.    ...

Building Web Frontend/UI for Local Docker Registry using SUSE Portus

If you are looking out for Web UI for your private Docker Registry, I would recommend to test-drive a tool called “Portus” powered by SUSE Team. Portus provides a useful and powerful UI on top of your registry. It is an open source authorization service and a user interface for the next generation of the Docker registry. Portus targets version 2 of the Docker Registry API. Docker Registry(a.k.a Docker Distribution)  is a storage and content delivery system, holding named Docker images. It is a stateless, highly scalable server side application that stores and lets you distribute Docker images. The Registry is open-source,...
