kubectl-point is a kubectl plugin that allows users to make use of an existing ingress controller to redirect domain names to specific ip addresses that the cluster has access to.
Requirement:
- go 1.16.x/1.17.x
To build:
$ go mod tidy
$ go build
And then mv the generated binary to your /usr/local/bin/kubectl-point
This creates an Ingress, a headless Service and custom Endpoint on your cluster that accepts a http call to example.org and redirects them to 10.0.0.1:8080
kubectl point example.org --to=10.0.0.1:8080
This creates an ingress for example.org that listens on both http and https and redirects them to 10.0.0.1:8080 and also attempts to generate the necessary tls certs with cert-manager. If your cluster does not have cert-manager (v1) installed, this command will error out.
kubectl point example.org --to=10.0.0.1:8080 --tls-auto
This looks for a tls.key and tls.crt in /certs and uses them to configure tls on your ingress controller
kubectl point example.org --to=10.0.0.1:8080 --tls-dir=/certs
Use the --tls-key and --tls-cert flag to specify the tls.key and tls.crt that will be sent to the ingress controller
kubectl point example.org --to=10.0.0.1:8080 --tls-key=/certs/tls.key --tls-cert=/certs/tls.crt
