Custom and use plugin authen and author on kong_ingress k8s

[MinhDuc010194]

hi everyone!
Is it possible to use a custom plugin like this link into kong_ingress?
https://konghq.com/blog/custom-authentication-and-authorization-framework-with-kong/
i want to try this one but I don't know how to add config like this link.
and after config is done how can I use this for kong_ingress.

Hi @MinhDuc010194,

You need to build a custom image that includes your plugin files and then deploy a KongPlugin to get it loaded.

If you're using the Helm chart there's a feature to load it via ConfigMap mounts:

https://github.com/Kong/charts/blob/main/charts/kong/values.yaml#L305-L324

Notes

This gets more complicated if you need custom credentials and things like that.

For instance in DBLESS mode you have to write the YAML directly and embed it in a secret:

https://docs.konghq.com/kubernetes-ingress-controller/1.3.x/guides/configuring-custom-entities/

In DB mode you can't do this at all via the KIC currently: you have to do it directly via the Kong Admin API.

yes. i realized and change to kong namespace. but now this is new err "(message: "declarative config is invalid: {plugins={{name=\"plugin 'myheader' not enabled; add it to the 'plugins' configuration property\"}}}")". how to enable plugin. Do I place it wrong? --> # Add plugin env
- name: KONG_PLUGINS
value: bundled,myheader
- name: KONG_LUA_PACKAGE_PATH
value: "/opt/?.lua;;"

No problem, what was the last thing you had to do in order to get things working?

[MinhDuc010194]

I had to move this config

- name: KONG_PLUGINS
value: bundled,myheader
- name: KONG_LUA_PACKAGE_PATH
value: "/opt/?.lua;;

To below here

spec:
      containers:
      - env:
