Release Notes

Patch release with some bug fixes and some API changes for experimental image and runtime plugins. This release also includes substantial updates for the new rootfs+layer image scheme and the rootless mode which are both still considered undocumented and experimental.

Noteworthy Bug Fixes

Updates to Experimental Features

  • A new preloaded+layer:// scheme for the ContainerSpec.Image property allows a client to request a droplet layer be added to the rootfs in the create call (rather than via a separate StreamIn call). This allows the final rootfs to be pre-created via copy-on-write in the layered filesystem rather than by extracting the droplet tarball in to a running container. (Note: this API is currently experimental and subject to change).
  • The Experimental Rootless Mode is nearing completion and now supports limiting cpu and memory usage for created containers.
  • Numerous updates have been made to the windows job to enable Garden-on-Windows support
  • Garden now reports metrics for StreamIn and Create to aid in debugging performance of image plugins (https://www.pivotaltracker.com/story/show/149914457).

Bosh Property Changes

  • Garden’s default port-pool range now starts from 61001 rather than 60000 to avoid colliding with the top of the ephemeral port range. This reduces the number of ports in the pool to 4534 but avoids potential conflicts with OS-assigned ports. Operators can use the garden.port_pool.start and garden.port_pool.size properties to change this range (https://www.pivotaltracker.com/story/show/117415775).
