It is very simple to do and can be done directly in Chrome or from an Elevated Command Prompt window in Windows 7 or 8. Using a Service named kube-dns abstracts away the implementation detail of which DNS provider is running behind that common name. ; resource_version - An opaque value that represents the internal Flushing your DNS cache can be a useful tool to resolve any host connection errors that you may experience with Google Chrome or other browsers. Explore five methods for service discovery in NGINX and NGINX Plus that use DNS records, including SRV records in NGINX Plus R9. We have released updates to NGINX Open Source, NGINX Plus, and NGINX Ingress Controller to fix a vulnerability in DNS resolution (CVE-2021-23017). All paths defined on other Ingresses for the host will be load balanced through the random selection of a backend server. On the DNS tab, you can then Add DNS servers and order them in order of use using the green arrows on the right side of the tab. To use it, install docker-compose. SMTP . If more than one Ingress is defined for a host and at least one Ingress uses nginx.ingress.kubernetes.io/affinity: cookie, then only paths on the Ingress using nginx.ingress.kubernetes.io/affinity will use session cookie affinity.

This is so that there is greater interoperability with workloads that relied on the legacy kube-dns Service name to resolve addresses internal to the cluster. If you do not already have a cluster, you can This is useful for setting up reoccuring services that are use often and/or have complex configurations. For Kubernetes, you can use kube-dns.kube-system here.
