Know issue with Kong 3.0.0, see Kong/kong#9337 (comment)

[dcominottim]

Hi, @Tieske. Thanks for the update (I opened the duplicate #368).

I am trying to form a picture of where we are regarding this issue, since #9337 (the supposed fix?) was merged a few months back but the issue still happens with the latest code from Pongo's master.

[Tieske]

that PR has 2 fixes in it, and after some internal discussion the 2nd fix was removed to keep it clean. But that is exactly the fix we need here. I am pushing to get this fixed though.

[dol]

As a workaround place your plugin files inside WSL home folder instead of accessing them on the Windows mount /mnt/c .

[nitinthewiz]

Since this issue is still open, I'd like add this here - I'm seeing this behavior in Kong 3.2.2 on macOS 13 using colima. This includes not seeing the issue on Kong 2.3.2. I understand that there's a fix in place since Oct 2022, but has anyone got this working on macOS with a non-Docker Desktop setup?

[Tieske]

@nitinthewiz just to verify, are you seeing this line in your logs;

nginx: [emerg] bind() to unix:/kong-plugin/servroot/worker_events.sock failed (22: Invalid argument)

That would indeed indicate it is the same issue (which hasn't been fixed yet, see my comment above)

[nitinthewiz]

@Tieske Thanks for asking for a clarification. I was tracking multiple issues to find a resolution and "Invalid argument" is not the error I'm seeing.

I'm seeing the following error -
nginx: [emerg] bind() to unix:/kong-plugin/servroot/worker_events.sock failed (1: Operation not permitted)

This seems to have been mentioned here, and by you here. I suppose it is not related to this issue. However, I don't see an issue tracking my error specifically.

I suppose just like Vagrant, this needs an absolute path solution for colima on macOS (or perhaps a more generalized solution for macOS?)

[Tieske]

The solution would be to make the Unix socket location configurable, or move it to a more appropriate system based location. (that's a Kong change however, not a Pongo change)

[antoineauger]

I was experiencing the same issue on Ubuntu 22.04 with rancher-desktop. This is kind of known, see rancher-sandbox/rancher-desktop#1209 for example. The fix mentioned here did not work for me.

As a temporary workaround, I managed to run pongo run -v by editing the volumes section of assets/docker-compose.yml:

  kong:
    image: ${KONG_TEST_IMAGE:-ignore_if_not_provided}
   ...
    volumes:
-      - ${PONGO_WD}:/kong-plugin
+      - /tmp/kong-plugin:/kong-plugin/servroot
+      - ${PONGO_WD}/spec:/kong-plugin/spec
+      - ${PONGO_WD}/kong:/kong-plugin/kong
+      - ${PONGO_WD}/.pongo:/kong-plugin/.pongo
+      - ${PONGO_WD}/.busted:/kong-plugin/.busted
+      - ${PONGO_WD}/.license-scripts:/kong-plugin/.license-scripts
+      - ${PONGO_WD}/kong-plugin-myplugin-0.1.0-1.rockspec:/kong-plugin/kong-plugin-myplugin-0.1.0-1.rockspec

[mfbmina]

Based on @antoineauger solution, I've tested some configuration and I only needed the following:

kong:
    image: ${KONG_TEST_IMAGE:-ignore_if_not_provided}
   ...
    volumes:
      - ${PONGO_WD}:/kong-plugin
      - /tmp/kong-plugin:/kong-plugin/servroot

[antoineauger]

@mfbmina Unfortunately, your simpler configuration did not work for my use case/tests. 😿
