Hi!

It's been a while since our last release. Most changes have focused around documentation but there are 2 notable changes:

Increase verbosity of credential chain errors Allow agent to not remove iptables rules on host Thanks to @mwmix and @theatrus for contributing the above.

v3.0

6 December 2018

v3 introduces a change to the gRPC API. Servers are compatible with v2.x Agents although v3 Agents require v3 Servers. Other breaking changes have been made so it's worth reading through docs/UPGRADING.md for more detail on moving from v2 to v3.

Notable changes:

  • #109 v3 API
  • #110 Restrict metadata routes. Everything other than credentials will be blocked by default
  • #122 Record Server error messages as Events on Pod
  • #131 Replace go-metrics with native Prometheus metrics client
  • #140 Example Grafana dashboard for Prometheus metrics
  • #163 Server manifests use 127.0.0.1 rather than localhost to avoid DNS
  • #173 Metadata Agent uses 301 rather than 308 redirects
  • #180 Fix race condition with xtables.lock
  • #193 Add optional pprof http handler to add monitoring in live clusters

A huge thanks to the following contributors for this release:

v2.8

1st June 2018

Notable changes:

  • #62 Documented interfaces to specify when using Kiam with amazon-vpc-cni.
  • #76 Wait for balancer to have addresses in Gateway. This helps prevent the following errors being reported by the health check command:
WARN[0000] error checking health: rpc error: code = Unavailable desc = there is no address available

v2.7

30th April 2018

Notable changes:

  • Fix Issue 43: updates to metadata api paths on m5/c5 instances
  • #41: Server allows for custom STS session durations with --session-duration
  • Server uses cache.NewIndexerInformer to maintain pod and namespace caches, this also addresses an error identified in Issue 46.
  • #54 Agents can use a ! prefix on interfaces when configuring iptables rules. This makes it possible to use Kiam with Amazon and Lyft's CNI plugins.
  • Servers will wait for the pod and namespache caches to perform a sync with the Kubernetes API server before accepting gRPC connections. This may cause servers to take longer to start but ensures they have recent state before performing any operations.
