Releases: cloudnativelabs/kube-router
v0.0.16 -- The KRaken Has Awoken
We're happy to say that kube-router is picking up steam! Big thanks to all the new users who are taking it for a spin and reporting bugs and showing us how they use kube-router's unique features. This release is a real doozy, and we look forward to the imminent beta release!
Notable Bug Fixes
d433fa5 Fix IPVS persistence flag (#160)
62900c7 NodePort service listens on all ip/interfaces in case of kube-proxy. Currently kube-router listens only on node IP. This fix introduces flag nodeport-bindon-all-ip with which you can have kube-proxy like behaviour. If not specified only nodeIP will be open for connections.
Enhancements
d6ea740 Dynamic gobgpd listener config, fix leaked listener (#156)
ca97d0d Adding ability to disable IP-in-IP tunnelining for cross node pod-to-pod connectivity where nodes are in different subnet. With tunneling disabled its expected that default gateway has learned the pod CIDR's allocated for all the nodes and can route the pod-to-pod traffic across nodes in different subnets

DaemonSet Upgrade Steps
image: cloudnativelabs/kube-router[:latest] + imagePullPolicy: Always
These are the default options in our manifests. In this scenario you just need to delete the pods so they are recreated. This will not interrupt cluster services/traffic.
kubectl -n kube-system delete pods -l k8s-app=kube-router
image: cloudnativelabs/kube-router:vX.X.X
If your image option is pinned to a specific version, you can upgrade using kubectl set image.
kubectl -n kube-system set image ds/kube-router kube-router=cloudnativelabs/kube-router:v0.0.16
kubectl -n kube-system delete pods -l k8s-app=kube-router
image: cloudnativelabs/kube-router-git:master
Already running the latest version huh? We like your style.

v0.0.15
This patch release has critical fix that affects distros with strict reverse path filtering. When nodes span across multiple subnets, Kube-router uses ip-in-ip tunneling. Fix in this release ensures traffic originates and leaves on same tunnel interface.

v0.0.12 - Important Bug Fixes
This release brings a number of bug fixes:
- An important update to the GoBGP library that fixes a leaking socket bug.
- If you've experienced degraded performance or failures over time with a kube-router powered cluster, this release should fix those issues.
Also included are a number of enhancements:
- Automatic Pod CIDR detection
--cluster-cidrflag is no longer needed for pod egress- Use
--enable-pod-egress=falseto disallow pod egress traffic outside the cluster
- Streamlined kubeadm integration
- ipip tunneling performance improvements between nodes in different networks.

v0.0.11
With this release kube-router adds support for pod-to-pod connectivity across the nodes in different subnets. In case of public clouds, you can deploy cluster with nodes spanning across mutliple availability zones. Kube-router ensures pod-to-pod connectivity across zones.
We also did scaling tests on service proxy implemented by Kube-router. As part of the effort, kube-router will now use docker libnetwork based ipvs library. Please see #101 and #106 for scaling test results.

v0.0.10
We're excited to announce the latest alpha version of kube-router! This release along with multiple bug fixes adds support for network policy v1 or GA version of network policy released as part of Kubernetes 1.7. Kube-router is also tested and verified to work well with Kubernetes latest release 1.7 release.
Upgrade Steps
You can update your DaemonSet to use the following cloudnativelabs/kube-router:v0.0.10 image to upgrade .
Please note that going forward from this release kube-router will take explicit --master/--kubeconfig argument. If not specfied will use incluster config.

Bug fix release
v0.0.9 0.0.9
v0.0.8
We're excited to announce the latest alpha version of kube-router!
With this version Kube-router now:
- publishes basic metrics related to services which can be scraped by prometheus.
- There are key fixes related how each node advertises routes to global peers.
- This release also includes a fix, where it automatically disables source-destination check for EC2 instances when running on AWS
Upgrade Steps
If you're using the cloudnativelabs/kube-router or cloudnativelabs/kube-router:latest tags in your kube-router DaemonSet, pull the latest image on your Kubernetes nodes by running this on each node:
docker pull cloudnativelabs/kube-router
And finally, delete the kube-router pods so that new ones use the new image:
kubectl -n kube-system delete pod -l k8s-app=kube-router
NOTE
We now have version-tagged images. You can update your DaemonSet to use the following cloudnativelabs/kube-router:v0.0.8.
