# Cilium
|
|
|
|
## Kube-proxy replacement with Cilium
|
|
|
|
Cilium can run without kube-proxy by setting `cilium_kube_proxy_replacement`
|
|
to `strict`.
|
|
|
|
Without kube-proxy, cilium needs to know the address of the kube-apiserver
|
|
and this must be set globally for all cilium components (agents and operators).
|
|
Hence, in this configuration in Kubespray, Cilium will always contact
|
|
the external loadbalancer (even from a node in the control plane)
|
|
and if there is no external load balancer It will ignore any local load
|
|
balancer deployed by Kubespray and **only contacts the first master**.
|
|
|
|
## Choose Cilium version
|
|
|
|
```yml
|
|
cilium_version: v1.8.9 ## or v1.9.6
|
|
```
|
|
|
|
## Add variable to config
|
|
|
|
Use following variables:
|
|
|
|
Example:
|
|
|
|
```yml
|
|
cilium_config_extra_vars:
|
|
enable-endpoint-routes: true
|
|
```
|
|
|
|
## Install Cilium Hubble
|
|
|
|
k8s-net-cilium.yml:
|
|
|
|
```yml
|
|
cilium_enable_hubble: true ## enable support hubble in cilium
|
|
cilium_hubble_install: true ## install hubble-relay, hubble-ui
|
|
cilium_hubble_tls_generate: true ## install hubble-certgen and generate certificates
|
|
```
|
|
|
|
To validate that Hubble UI is properly configured, set up a port forwarding for hubble-ui service:
|
|
|
|
```shell script
|
|
kubectl port-forward -n kube-system svc/hubble-ui 12000:80
|
|
```
|
|
|
|
and then open [http://localhost:12000/](http://localhost:12000/).
|
|
|
|
## Hubble metrics
|
|
|
|
```yml
|
|
cilium_enable_hubble_metrics: true
|
|
cilium_hubble_metrics:
|
|
- dns
|
|
- drop
|
|
- tcp
|
|
- flow
|
|
- icmp
|
|
- http
|
|
```
