Controller.json

Custom Resource Definition (CRD) information like the domain, group, image, repository, etc. are stored in the controller.json file. This skeleton file for controller.json is created when you create a CRAFT application in quickstart:

"group": "",
"resource": "",
"repo": "",
"domain": "",
"namespace": "",
"version": "",
"operator_image": "",
"image": "",
"imagePullSecrets": "",
"imagePullPolicy": "",
"cpu_limit": "",
"memory_limit": "",
"vault_addr": "",
"runOnce": "",
"reconcileFreq": ""

This table explains the controller.json attributes:

Here’s an example of a controller.json file for the Wordpress operator:

{
 "group": "wordpress",
  "resource": "WordpressAPI",
  "repo": "wordpress",
  "domain": "salesforce.com",
  "namespace": "default",
  "version": "v1",
  "operator_image": "ops0-artifactrepo1-0-prd.data.sfdc.net/cco/wordpress-operator",
  "image": "ops0-artifactrepo1-0-prd.data.sfdc.net/cco/wordpress:latest",
  "imagePullSecrets": "registrycredential",
  "imagePullPolicy": "IfNotPresent",
  "cpu_limit": "500m",
  "memory_limit": "200Mi",
  "vault_addr": "http://10.215.194.253:8200"
}
