Create a dockerconfigjson

Using user, password and url

With this template we can create an external secret to pull images from a private repository if we have the username, password and url stored in our secret store. The important thing here is the template. The data section can be different for every secret store.

apiVersion: external-secrets.io/v1beta1
kind: ExternalSecret
metadata:
  name: privatepull
spec:
  data:
  - remoteRef:
      key: PULL-APPS-U
    secretKey: username

    secretKey: password
  - remoteRef:
      key: PULL-APPS-URL
    secretKey: url

    kind: SecretStore
    name: mystore

            "auths": {
              "{{ .url  }}": {
                "username": "{{ .username }}",
                "password": "{{ .password }}",
                "email": ""
              }
            }
          }
      type: kubernetes.io/dockerconfigjson
