Hi everyone, I'm adding unit tests to kong via luaunit, in a dockerized kong environment. This is the dockerfile

FROM kong:2.0.3-alpine
USER root
WORKDIR /usr/local
COPY . .
RUN luarocks make *.rockspec
RUN ./run-tests.sh
USER kong

and here's the run-tests script

#!/bin/sh

find . -name "*-test.lua" |
    while read -r filename; do
        echo "Executing test for: $filename"
        /usr/local/openresty/luajit/bin/luajit "$filename"
    done

This is how I'm running the individual unit tests. I have added stubs for some dependencies, but the actual code makes use of kong's logging feature kong.log("...")

When I run the tests, it shows that the global kong is a nil value

If i try to fix it via

kong = require("kong")

I get an error:

/usr/local/openresty/luajit/bin/luajit: /usr/local/share/lua/5.1/kong/init.lua:30: lua-resty-core must be loaded; make sure 'lua_load_resty_core' is not disabled.
stack traceback:
        [C]: in function 'assert'
        /usr/local/share/lua/5.1/kong/init.lua:30: in main chunk

Currently I've added a hack fix for the same - by doing

kong = {}
function kong.log(log_message) print("Kong log: " .. tostring(log_message)) end

But could anyone help out with this?

Kong newbie here! I'm evaluating Kong for my use case. How do I do dynamic IP blacklisting and how to ban an IP for some x duration.

2 replies

Couldn't find help for these online.

Is it possible to do these in kong or should I use something like fail2ban to achieve this.

Hello All! still testing LDAP plugin for kong. I have 'echo' service up and running and would like to test the ldap plugin against this service. I have enabled this plugin as well as passed the annotation to the echo service to include it. When i go to curl the 'echo' service I base64 encode my user and password but does not work. I encode the LDAP admin account and password and a I can get in. How can I get LDAP plugin to use the admin account to verify that my user id / password rather than having to use the LDAP admin? Seems like that would defeat the purpose

Hey guys! I'm facing an issue with go-lang pointers in configuration type. Here is my config

type Config struct {
  NestedKey struct {
    ListOfValues     []*string `json: "list_of_values,omitempty"`
  }
}

func (conf Config) Access(kong *pdk.PDK) {...}

And when I send an HTTP request in order to create a plugin it returns an error like

schema violation (config.nestedkey: {\n  list_of_values = \"unknown field\"\n})

Please help me to solve this issue...

Hey gus! Is the workspace feature available only in Kong EE?

jeremyjpj0916

@jeremyjpj0916

well its in the CE database as well with less fields, I just don't think the admin api calls are exposed for it. Enterprise docs list it here: https://docs.konghq.com/enterprise/2.1.x/admin-api/workspaces/reference/ , ofc you can always fork and add a wrapper to edit your own workspace in open source but I can't think of any value for it in the CE with how its defined right now.

Hi all, I'm writing a go plugin and am wondering how I can expose multiple environment variables to the plugin? I found this issue: Kong/kong#6149 that suggests setting KONG_NGINX_MAIN_ENV. This works for a single variable, but I need to expose multiple. Any idea how I can do that? Thanks in advance.

Hi all, I have installed kong on Kubernetes pod. While configuring the service in kong I used kubernetes service name as "host". When accessing the API through Kong , I am getting error "name resolution failed".
So is it possible to use the kubernetes service name as host in kong service configuration?

Hi All, I recently started working with kong and am looking into some insight into the workings of the bundled plugin "response-ratelimiting". I have tried creating a rate limit at a consumer level and the other at a service level. I am currently observing only the consumer limit is being applied. Is this expected behavior? If so why?

mvanmeerbeck

@mvanmeerbeck

Hello Kongers,
I'm currently considering using Kong for my gateway since i need rate limit on my APIs. I need to limit the API per pricing plan. Is there a way to do that ?
I've seen that we can limit an API per consumer. But that's not enough for my case, i would need to define a rate limit per "type of user" (maybe with a tag?) but be counted by "credential".

hi there , suppose a situation in which a consumer has rate-limit plugin (200 request per month ), and this consumer uses 100 requests of his rate-limit , and then if we backup the kong by deck and restore the kong entities in another server , we see that mentioned consumer again has the rate-limit of 200 requests remaining ( otherwise this consumer should have the 100 request reamining ) and it show that the metrics of rate-limit plugin reset after backup-restore of kong . what should i do to solve this issue ?

Hi, my microservices receive https traffic on a non-443 port.

While accessing my website api - I get the following error in the network tab in Chrome
(failed)net::ERR_HTTP2_PROTOCOL_ERROR

and the logs of the kong proxy pod show that its using http to access the pods of the application

I have the following questions

How do I make sure it uses https to communicate with my microservices? In the official K8s ingress, I just an annotation : nginx.ingress.kubernetes.io/backend-protocol: "HTTPS"
How do I enforce HTTP 1.1 instead of HTTP2?
