CoreOS Moves From Btrfs To EXT4 + OverlayFS - Phoronix. CoreOS developers have had enough issues with the Btrfs file-system that they've decided to move from using the Btrfs file-system to instead use EXT4 plus OverlayFS.

CoreOS Moves From Btrfs To EXT4 + OverlayFS - Phoronix

Since December the CoreOS developers and stakeholders have been debating switching off Btrfs due to issues. The original proposal mentioned, "We chose btrfs because it was the most straightforward Docker graph driver at the time. But, CoreOS users have regularly reported bugs against btrfs including: out of disk space errors, metadata rebalancing problems requiring manual intervention and generally slow performance when compared to other filesystems. " Many CoreOS users and developers were in favor of moving away from Btrfs due to issues of this next-generation Linux file-system going through growing pains.

Easing them off of Btrfs was that OverlayFS was finally merged in Linux 3.18. After one month of discussions, CoreOS has indeed moved off of Btrfs by default to instead use EXT4+OverlayFS for new installations. It’s Here: Docker 1.0. June 9, 2014 9:30am PT On March 20, 2013, we released the first version of Docker.

It’s Here: Docker 1.0

After 15 months, 8,741 commits from more than 460 contributors, 2.75 million downloads, over 14,000 “Dockerized” apps, and feedback from 10s of 1000s of users about their experience with Docker, from a single container on a laptop to 1000s in production in the cloud … we’re excited to announce that it’s here: Docker 1.0. It’s a milestone we celebrate with the entire Docker community, for without the community’s contributions, pull requests, and answering of each other’s questions on IRC and forums none of this would have been possible. And without the community hosting more than 250 meetups in 90 cities across 30 countries, the awareness, understanding, and excitement of Docker would not have spread as rapidly. What’s In A Number? We think this milestone means several things: First, while many organizations have cheerfully ignored our “Do not run in production!” Enough Already – What’s The Latest In 1.0? 1.5: IPv6 support, read-only containers, stats, “named Dockerfiles” and more.

The Docker project team wanted to start the new year out right with something awesome; that’s why we’re super excited to announce the first Docker release for 2015.

1.5: IPv6 support, read-only containers, stats, “named Dockerfiles” and more

We’ve smashed many long-standing, annoying bugs and merged a few awesome features that both the community and maintainers are excited about. Let’s check out what’s in Docker 1.5. IPv6 support Contributed by: Malte Janduda – Link to PR You can now allocate an ipv6 address to each container with the new ‘–ipv6’ flag. Here’s a fun and easy way to try out this new feature: Read-only containers Contributed by: Michael Crosby – Link to PR You can now enable a read-only filesystem for your container via the --read-only flag. Stats Contributed by: Michael Crosby – Link to PR Containers are cool.

OpenStack et Docker, futurs piliers de l'infrastructure IT des entreprises

(crédit : D.R.) Une étude menée par Rightscale en début d'année fait état d'une montée en puissance du cloud hybride. Jusqu'alors dominantes, certaines technologies très utilisées comme vSphere/vCenter de VMware dans le cloud privé ou encore Chef dans la gestion des configurations doivent faire face à la percée des stars montantes comme OpenStack et Docker. En janvier 2015, RightScale a interrogé 930 professionnels informatiques au profil technique dans des organisations pour en savoir plus en matière de leur adoption envers le cloud computing. Les résultats de son étude RightScale 2015 State of the Cloud Report montrent que 93% des organisations font tourner ou mènent actuellement des expérimentations en matière de cloud (IaaS).
