Docker has added a new feature to allow alternate logging drivers, and soon you’ll be able to use journald as a supported driver.
With Docker 1.6 they support json-file, which is the old default, syslog, or no logging at all.

Container.Camp Presentation and Slides
Last week I had the opportunity to attend Container.Camp in San Francisco and present an introduction to Project Atomic. If you didn’t get to attend – or just want to relive the talk – you can find it on YouTube (also embedded below).
If you’d like to see all of the Container.Camp presentations, they’re available on YouTube under the Container.Camp channel. Thanks again to the Container.Camp organizers for inviting me to speak, it was a great event. Fantastic speakers, really interesting venue, and a great crowd.
Thoughts on Project Photon
Earlier this week, VMware launched its lightweight operating system tailored for running Linux containers. Naturally, I was interested to see what VMware was cooking up, since that’s the same target we have for Project Atomic.
First, it’s great to see more interest in solving the problem of running Linux containers at scale. Even better, VMware seems to be interested in doing its work in the open. It’s always great to see companies that traditionally lean towards proprietary software taking steps towards doing more open source work. More open source work, even when it’s similar to other projects, is almost always a Good Thing™.
That said, I’d like to encourage VMware to consider whether they need to start from scratch with Project Photon. Creating an operating system from scratch is not trivial in the least, and there’s a lot of work that could be shared between Photon and Atomic.
Using Environment Substitution with the Atomic Command
I recently published a post on the Red Hat Developer Blog about the Atomic command that we’ve been working on for the last few months.
The Atomic command (/usr/bin/atomic) is a high-level, coherent entrypoint for Atomic Host systems, and aims to fill in the gaps in Linux container implementations.
Atomic News: Fedora 22 Beta, CentOS Update Glitch (and Fix!)
In case you missed it, Fedora 22 Beta was released today with images for using Fedora Atomic Host. If you’re looking for qcow2 images for KVM, Vagrant Boxes, or EC2 AMIs, you’ll find them all there. But wait, there’s more!
Not listed on the product page, but worth checking out, is an ISO you can use to install Atomic on bare metal (or in another virtualization platform of your choice). You can find that image here, along with its CHECKSUM file.
