This week we're announcing the 1.0 release of rkt, and this guide will help you get up and running with the project, all the way from installing rkt to building and running your own app container image.

Follow along with the steps below while you check out this screencast that illustrates each:

rkt v0.10.0 is here and marks another important milestone on our path to creating the most secure and composable container runtime. This release includes an improved user interface and a preview of the rkt service API, making it even easier to experiment with rkt in your microservices architectures.

The latest release of rkt, a container runtime, introduced many valuable features in v0.8. One notable feature is the ability to effortlessly run rkt with flannel, a software-defined network for containers. This makes it easy for all the containers in your cluster to have a unique IP over which they can converse with each other.

Today we are releasing rkt v0.8.0. rkt is an application container runtime built to be efficient, secure and composable for production environments.

This release includes new security features, including initial support for user namespaces and enhanced container isolation using hardware virtualization. We have also introduced a number of improvements such as host journal integration, container socket activation, improved image caching, and speed enhancements.

Today we are announcing rkt v0.7.0. rkt is an app container runtime built to be efficient, secure and composable for production environments. This release includes new subcommands for a rkt image to manipulate images from the local store, a new build system based on autotools and integration with SELinux. These new capabilities improve the user experience, make it easier to build future features and improve security isolation between containers.

Note on rkt and OCP

Today we’re pleased to announce that CoreOS, Docker, and a large group of industry leaders are working together on a standard container format through the formation of the Open Container Project (OCP). OCP is housed under the Linux Foundation, and is chartered to establish common standards for software containers. This announcement means we are starting to see the concepts behind the App Container spec and Docker converge. This is a win for both users of containers and our industry at large.

Today is the inaugural CoreOS Fest, the community event for distributed systems and application containers. We at CoreOS are here to celebrate you – those who want to join us on a journey to secure the backend of the Internet and build distributed systems technologies to bring web scale architecture to any organization.

Since the last rkt release a few weeks ago, development has continued apace, and today we're happy to announce rkt v0.5.4. This release includes a number of new features and improvements across the board, including authentication for image fetching, per-application arguments, running from pod manifests, and port forwarding support – check below the break for more details.

Today VMware shipped rkt, the application container runtime, and made it available to VMware customers in Project Photon. VMware also announced their support of the App Container spec, of which rkt is the first implementation.

rkt is a new container runtime for applications, intended to meet the most demanding production requirements of security, efficiency and composability. rkt is also an implementation of the emerging Application Container (appc) specification, an open specification defining how applications can be run in containers. Today we are announcing the next major release of rkt, v0.5, with a number of new features that bring us closer to these goals, and want to give an update on the upcoming roadmap for the rkt project.
