1.5.0-alpha3

Alpha release of kops 1.5.0, optimized for the kubernetes 1.5 series

It is recommended that you pass --channel alpha when using this release, to get the version that will shortly be the stable release. But remember that clusters created with --channel alpha will remain on the alpha channel until you change them.

Changes since 1.5.0-alpha2

• Fix cleanup of NAT Gateways (thanks @tsupertramp for finding)
• Fix cleanup of bastion IAM roles & DNS names (thanks @AlexLast for finding)
• Fix docker installation on CentOS / RHEL

1.5.0-alpha2

Alpha release of kops 1.5.0, optimized for the kubernetes 1.5 series

• It is recommended that you pass --channel alpha when using this release, to get the version that will shortly be the stable release. But remember that clusters created with --channel alpha will remain on the alpha channel until you change them.

Highlights

• Network overlays: --networking calico --networking kopeio-vxlan or --networking weave
• Isolated networks (nodes do not have public IPs): --topology private
• Bastion support for isolated networks: --bastion
• Private hosted zone: --dns private
• API can be exposed via DNS, or by an internet-facing ELB, or by a private ELB
• Enhanced model that allows for complex subnet configurations

v1.4.4

Users of the 1.4 kops series are highly recommended to upgrade.

• Fix issue where instances running kubernetes 1.5 would not restart correctly: #1173

v1.4.3

This version of kops fixes problems that prevent a 1.5 cluster starting; a 1.5 release of kops with all the configuration changes for optimal operation of kubernetes 1.5 will be following shortly and will be named 1.5.x.

• When running with k8s 1.5, will pass --anonymous-auth=false and will no longer pass removed --configure-cbr0 flag

v1.4.1

• Fix dns-controller when multiple HostedZones with the same name
• Initial support for CentOS / RHEL7
• Initial k8s-style API & examples
