Advancing Docker Security: Docker 1.4.0 and 1.3.3 Releases

We’re pleased to announce that we have today released Docker Engine 1.4. What’s in it? As Solomon Hykes described last week at DockerCon Europe, its major “feature” is an emphasis on bug fixes and platform stability. Over 180 commits for fixes were merged! Docker 1.4 also adds the Overlay Filesystem as a new, experimental, storage driver. (see release notes and bump branch). Today, we also release Docker Engine 1.3.3 fixing three vulnerabilities (see advisory). These fixes are also in version 1.4.0. Here is a bit more info on the fixes: On November 24, 2014, we released Docker 1.3.2 to remedy two critical issues which could be exploited by a malicious image to break out of Docker container. Please see our security advisory for more details. After releasing 1.3.2, we discovered additional vulnerabilities that could be exploited by a malicious Dockerfile, image, or Continue reading…

Announcing Docker Hub Enterprise: Managing Distributed Applications Behind the Firewall

DockerCon! There’s been a ton of exciting new technology showcased at DockerCon and it’s been thrilling to announce Docker Hub Enterprise on stage and to get such positive feedback on it. There were 500+ people in person today hoping to learn how to manage and maintain their distributed applications, and I’m excited to say that those benefits are coming to the enterprise as a turn-key solution. The Docker open platform for distributed applications has enjoyed explosive growth, but prior to today’s announcement, enterprises that wanted to use Docker for business critical, differentiated applications had to rely on internal tools hacked on top of the open source project or 3rd party offerings. With Docker Hub Enterprise, we’re promising to meet this need with a behind the firewall, enterprise-grade solution. We’ve gained a lot of expertise from hosting Docker Hub, we’ve combined Continue reading…

Report: Burrito Quest I

At Docker, we are lucky to be able to spend time exploring San Francisco, one of the world’s great cities in terms of culture, architecture and, of course, burritos. Forget about crabs or sourdough, what San Francisco does best is the burrito, that noble combination of beans, meat, cheese, salsa, and love, all in a convenient wrapper that let’s you eat it one-handed. And. like the City itself, the burrito is incredibly diverse. Do you prefer black beans or pintos? Are you a carnivore who craves the al pastor and the carne asada, or do you seek out the elusive perfect chile relleno burrito (the turducken of Mexico)? So many options, so many questions. As an engineer-driven company, we needed to know the optimal solution. We had to know where to find the City’s finest burrito. And so it came Continue reading…

Announcing Docker 1.1.0

The hardworking folk at Docker, Inc. are proud to announce the release of version 1.1.0 of Docker. We’ve made improvements throughout the Docker ecosystem, including updates to Docker Engine, Docker Hub, and our documentation. Highlights include these new features: New .dockerignore functionality You can now add a .dockerignore file next to your `Dockerfile` and Docker will ignore files and directories specified in that file when sending the build context to the daemon. Example: https://github.com/dotcloud/docker/blob/master/.dockerignore Pause containers during commit Doing a commit on a running container was not recommended because you could end up with files in an inconsistent state (for example, if they were being written during the commit). Containers are now paused when a commit is made to them. You can disable this feature with docker commit –pause=false <container_id>. Tailing logs You can now tail the logs of a container. For Continue reading…

Dockercon: Conference Recap

Wow! What a week! Wait, what? It’s only Tuesday? Well, you can’t blame me for being disoriented, because after two full days of Dockercon, it feels like the world is shifting under my feet. Shifting where, you ask? To containers! Containers are everywhere, from Spotify to Gilt, Yelp to Groupon. There are containers at Google, IBM, RedHat, and Microsoft. From dev to test to deploy, developers of every stripe are using Docker containers to make their jobs easier and more productive. Here are just a few examples of the amazing things we learned that people are doing with Docker.  Yelp uses Docker to help them build a smarter, more reliable application stack. Heroku develops interoperable containers with Dockerfiles that emulate Buildpacks to reduce fear, uncertainty and doubt. New Relic has built a tool called Centurion that talks to a fleet Continue reading…

Dockercon Day 1: Keynote Highlights

The first day of Dockercon started early, with sleepy attendees and manic marketing people milling about a big breakfast spread of fruit, pastry, an oatmeal bar and, because this is San Francisco after all, breakfast burritos. Coffee flows copiously and the room starts to fill, slowly at first and then with a rush of people crowding the registration tables. As the coffee flows faster, the chatter picks up and ideas start flowing too. I hear three new ideas for Docker projects and it’s not even 8 a.m. yet. These people are excited! The chatter fills the air with lots of languages: English, French, Australian, Ruby, Go, Python. By 8:30 it’s as crowded as a New York subway at rush hour. A clump of Docker employees worry that CTO Solomon Hykes is late. Apparently he was coding (or possibly tweeting) until 4 a.m. But there’s no time Continue reading…
