Add RBAC, healthchecks, autoscalers and update Calico to v2.5.1 #51237

gunjan5 · 2017-08-24T01:23:38Z

What this PR does / why we need it:

Updates Calico to v2.5
- Calico/node to v2.5.1
- Calico CNI to v1.10.0
- Typha to v0.4.1
Enable health check endpoints
- Add Readiness probe for calico-node and Typha
- Add Liveness probe for calico-node and Typha
Add RBAC manifest
- With calico ClusterRole, ServiceAccount and ClusterRoleBinding
Add Calico CRDs in the Calico manifest (only works for k8s v1.7+)
Add vertical autoscaler for calico-node and Typha
Add horizontal autoscaler for Typha

Release note:

Calico has been updated to v2.5, RBAC added, and is now automatically scaled when GCE clusters are resized.

Hi @gunjan5. Thanks for your PR.

I'm waiting for a kubernetes member to verify that this patch is reasonable to test. If it is, they should reply with /ok-to-test on its own line. Until that is done, I will not automatically test new commits in this PR, but the usual testing commands by org members will still work. Regular contributors should join the org to skip this step.

I understand the commands that are listed here.

Instructions for interacting with me using PR comments are available here. If you have questions or suggestions related to my behavior, please file an issue against the kubernetes/test-infra repository. I understand the commands that are listed here.

false right - ip-masq-agent will be used?

that's because "snat": true only applies to local host traffic. See https://github.com/containernetworking/plugins/tree/master/plugins/meta/portmap#snat

@caseydavenport spotted that if we try to reach hostport from the same node as the hostport pod with localhost:<hostport> it won't work without snat: true

This shouldn't affect ip-masq-agent since this is only for the localhost traffic

Yep, this is just for the hostport plugin, not general masquerade (which will still be done by the ip-masq-agent).

The hostport plugin needs this setting in order to allow users to do curl localhost:hostport successfully.

should ENABLE_IP_MASQ_AGENT=true be added where network policy provider is set?

we are thinking of doing that in a separate PR later, since it might need more changes for example node labels, etc.

ok, I think I was confusing that with "ipMasq": true
