Docker and Broad Industry Coalition Unite to Create Open Container Project
This morning, Docker, along with a broad coalition of vendors, users, start-ups, and industry leaders, made one of the more significant [announcements] in the history of containerization. In brief, we are coming together to form a minimalist, non-profit, openly governed project, The Open Container Project, under the auspices of the Linux Foundation for the express […]
Introducing runC: a lightweight universal container runtime
Spinning Out Docker’s Plumbing: Part 1: Introducing runC On Infrastructure Plumbing To build a platform like Docker you need a lot of infrastructure plumbing; in fact over the past two years even though our code base has grown to tens of thousands of lines of code; roughly 50% of it is plumbing! Infrastructure plumbing is […]
Setting Up a Minecraft Server Using Docker – Part 1
This is a quick tutorial demonstrating how to set up a local Minecraft server on Docker using Kitematic. Create a Minecraft Server Container First, if you haven’t yet done so, download and start Kitematic. Once installed and running, create a container from the recommended Minecraft image by clicking the “Create” button.
Kitematic a Docker GUI joins the Docker family
We are thrilled to announce the acquisition of Kitematic, the fastest and easiest way to use Docker on the Mac. Because Docker is a tool for developers, we find that the developers in the ecosystem build the best tools for Docker. Orchard’s Fig (now Compose) and SocketPlane are great examples of where great ideas were generated in […]
Docker Desktop 0.9: Introducing Execution Drivers and libcontainer
Fellow Dockers, Today we are happy to introduce Docker 0.9. With this release we are continuing our focus on quality over features, shrinking and stabilizing the core, and providing first-class support for all major operating systems. In addition to dozen of bug fixes, Docker 0.9 includes 2 major improvements: execution drivers and libcontainer. As usual, […]
Docker 0.6.5: name your containers, link them together, selectively publish ports, and more
Today we’re happy to announce Docker 0.6.5. Don’t be fooled by the version number: this is a significant release! Think of it as a preparation for 0.7, which will be even more significant. In addition to numerous bug fixes, this release introduces container naming, links between containers, better host integration, and advanced port redirects. A big thank […]
Call me Moby Dock
Last month we asked the Docker community to vote for the name of the Docker whale. We received 411 votes and today we are excited to announce that the community chose Moby Dock.
Gathering LXC and Docker containers metrics
Linux Containers rely on control groups which not only track groups of processes, but also expose a lot of metrics about CPU, memory, and block I/O usage. We will see how to access those metrics, and how to obtain network usage metrics as well. This is relevant for “pure” LXC containers, as well as for […]
Docker can now run within Docker
One of the (many!) features of Docker 0.6 is the new “privileged” mode for containers. It allows you to run some containers with (almost) all the capabilities of their host machine, regarding kernel features and device access. Among the (many!) possibilities of the “privileged” mode, you can now run Docker within Docker itself. First, we […]
How to use your own Registry
One of the things that makes Docker so useful is how easy it is to pull ready-to-use images from a central location, Docker’s Central Registry. It is just as easy to push your own image (or collection of tagged images as a repository) to the same public registry so that everyone can benefit from your newly Dockerized service. […]
