Engine 1.9.0
- Freeze: 2015-10-12
- Release: 2015-10-29
#15187 User namespaces
User namespaces are a long awaited feature, on which Phil Estes (@estesp) did some amazing work (see #12648). Unfortunately, the integration unexpectedly conflicted with the recent introduction of libnetwork.
We want to fix this for 1.9.0 and be able to merge Phil's work, which means:
- All containers have their own user namespace.
- A daemon-wide setting remaps the root user for all containers.
#15188 Better API implementation
We would like to rewrite our API, not to change the endpoint in a first phase, but at least to have a better, typed, self-documented, versioned version of the Docker API that we could share between Engine and Swarm.
#14298 Progress towards a client-side builder
As explained in the roadmap document, we want to enable client-side build.
#14212 Progress towards the OCI integration
The Engine currently has several compiled-in execdriver implementations, the default one being libcontainer. We the apparition of the Open Containers Initiative, we want the Engine to have a single execution backend capable of shelling-out to an OCI compliant binary. Currently, the standard and default implementation of such binary is runC.
It's unlikely that this will ship as the sole, default execution backend for Docker 1.9.0, but we intend to show some progress in a separate branch.
