CyVerse Ansible k3s

This role will apply a yaml to k8s and make an ingress using the given ports.

Requirements

This role assumes you have k8s or some variant such as k3s set up, and it was tested with k3s. It also assumes you have any services you want to use set up already.

Role Variables

The following table lists optional ansible variables along with the default values if not defined.

Variable Name	Default value if not defined	Description
K8S_RESOURCE	None	a required variable that is the .yaml file you want applied or an http address to one.
IS_HTTP	true	indicates that you are using a http link to a yaml file. set to false to use a string of a full file.
IS_BASE64	false	indicates that you are using a base64 version of a file string. set to false to use a normal string.
K3S_PORTS	None	a required variable that is a list of "port-service-name:port_numbers" such as ["port-servicea:80","port-serviceb:8080"] which will be used in the ingress
