Fix kube-proxy configuration for kubeadm (#3958) · 80379f6c

Chad Swenson authored 6 years ago

- Creates and defaults an ansible variable for every configuration option in the `kubeproxy.config.k8s.io/v1alpha1` type spec
  - Fixes vars that were orphaned by removing non-kubeadm
  - Fixes previously harcoded kubeadm values
- Introduces a `main` directory for role default files per component (requires ansible 2.6.0+)
  - Split out just `kube-proxy.yml` in this first effort
- Removes the kube-proxy server field patch task

We should continue to pull out other components from `main.yml` into their own defaults files as I did here for `defaults/main/kube-proxy.yml`. I hope for and will need others to join me in this refactoring across the project until each component config template has a matching role defaults file, with shared defaults in `kubespray-defaults` or `downloads`

Macvlan

How to use it

Enable macvlan in group_vars/k8s_cluster/k8s_cluster.yml

...
kube_network_plugin: macvlan
...

Adjust the macvlan_interface in group_vars/k8s_cluster/k8s-net-macvlan.yml or by host in the host.yml file:

all:
  hosts:
    node1:
      ip: 10.2.2.1
      access_ip: 10.2.2.1
      ansible_host: 10.2.2.1
      macvlan_interface: ens5

Issue encountered

Service DNS

reply from unexpected source:

add kube_proxy_masquerade_all: true in group_vars/all/all.yml

Disable nodelocaldns

The nodelocal dns IP is not reacheable.

Disable it in sample/group_vars/k8s_cluster/k8s_cluster.yml

enable_nodelocaldns: false
