The `nginx-proxy` container is deployed on every node that does not have the `controlplane` role. It provides access to all the nodes with the `controlplane` role by dynamically generating the NGINX configuration based on available nodes with the `controlplane` role.
|
|
|
|
## Check if the Container is Running
|
|
|
|
The container is called `nginx-proxy` and should have status `Up`. The duration shown after `Up` is the time the container has been running.
|
|
|
|
```
|
|
docker ps -a -f=name=nginx-proxy
|
|
```
|
|
|
|
Example output:
|
|
|
|
```
|
|
docker ps -a -f=name=nginx-proxy
|
|
CONTAINER ID IMAGE COMMAND CREATED STATUS PORTS NAMES
|
|
c3e933687c0e rancher/rke-tools:v0.1.15 "nginx-proxy CP_HO..." 3 hours ago Up 3 hours nginx-proxy
|
|
```
|
|
|
|
## Check Generated NGINX Configuration
|
|
|
|
The generated configuration should include the IP addresses of the nodes with the `controlplane` role. The configuration can be checked using the following command:
|
|
|
|
```
|
|
docker exec nginx-proxy cat /etc/nginx/nginx.conf
|
|
```
|
|
|
|
Example output:
|
|
```
|
|
error_log stderr notice;
|
|
|
|
worker_processes auto;
|
|
events {
|
|
multi_accept on;
|
|
use epoll;
|
|
worker_connections 1024;
|
|
}
|
|
|
|
stream {
|
|
upstream kube_apiserver {
|
|
|
|
server ip_of_controlplane_node1:6443;
|
|
|
|
server ip_of_controlplane_node2:6443;
|
|
|
|
}
|
|
|
|
server {
|
|
listen 6443;
|
|

|
|
proxy_timeout 30;
|
|
proxy_connect_timeout 2s;
|
|
|
|
}
|
|
|
|
}
|
|
```
|
|
|
|
## nginx-proxy Container Logging
|
|
|
|
The logging of the containers can contain information on what the problem could be.
|
|
|
|
```
|
|
docker logs nginx-proxy
|
|
``` |
