How to set node ip as nameserver in dnsConfig?
dnsConfig
support up to 3 IP addresses specified so theoretically you could hard code it in the nameservers
field. However as a workaround you can pass node ip address as a env variable and then pass it to the pod. Example:
spec: containers: - name: envar-demo-container command: ["/bin/sh"] args: ["-c", "printenv NODE_IP >> /etc/resolv.conf"] image: nginx env: - name: NODE_IP valueFrom: fieldRef: fieldPath: status.hostIP
fieldPath: status.hostIP
takes IP address of the node that pod is deployed on and saves it as a environment variable. Then it is written to /etc/resolv.conf
.
