Release v0.56.0
Versions
- rancher/server:v0.56.0
- rancher/agent:v0.8.2
- rancher/agent-instance:v0.6.0
- rancher-compose-v0.7.1
New Features
- Improved Rancher Managed Network [#2944, #2963, #2901] - Rancher's overlay networking using IPSec has been refactored with multiple fixes including replacing the current raccoon IKE keying daemon to charon. This should help with overall performance and stability issues found in our older implementation.
- NOTE: This is a fairly large change to our networking and if your network does not upgrade properly due to a timing issues when stopping and starting charon/racoon, please reboot the network agent container on the affected hosts. It's also possible that during the network agent restart, you may hit issue #1406. If that happens, you will need to reboot the host to correct the networking.
- NOTE2: Please do not upgrade if you are using CoreOS. Please use v0.56.1.
- UI Enhancements - We have added a few enhancements to the current UI:
- Added a new "System Stack" tab to differentiate between user application stacks vs system stacks (i.e. Convoy and external DNS providers).
- Added a new Help page located on the top navigation that includes integration with Rancher forums, Github projects, and FAQ.
- Improved UI performance and responsiveness.
- Added many UI fixes. Major ones will be listed below.
- Experimental: Added a new optional dark theme to the UI. This is a work in progress as we continue to optimize the UI for a darker theme over the upcoming releases.
- Added new health check action strategies [#3076] - The current behavior of health check failure is to immediately destroy and re-create. Starting with this release, Rancher now supports the following strategies:
- destroy - current default behavior
- noop - do nothing and simply provide an indication that the instance is unhealthy
- quorum - allow users to define a quorum size, less than equal to the service scale size, such that Rancher will not attempt to recreate containers until the number of healthy containers is less than the quorum size.
- Rancher Metadata Service Update [#3144] - The metadata service has now been updated to allow queries to /stack/services and /service/containers to return the full objects rather than name only. This is to make queries more efficient without having to query for the containers or services once the name was known. NOTE : We have bumped the current version of metadata service from 2015-07-25 to 2015-12-19 and have also pointed /latest -> 2015-12-19. If you were using /latest prior to this release, please make changes according as the return values have now been changed.
Rancher Catalog
- Added PointHQ DNS [rancher/rancher-catalog#75] Thanks @haswalt!
- Updated Convoy GlusterFS and Convoy NFS [#2796] with improvements to take advantage of the new fixes to managing deletion of volumes. Unfortunately with the major changes that were added, upgrades are not supported from v0.1 to v0.2. A new stack needs to be created.
