Hi As far I know go plugins are binary files (.so) and they are bigger than ConfigMap/Secret size limit. So have can I load go plugin to kong in dbless mode? For now, I’ve added sidecar that is coping go plugin file to kong container. But I’ve a problem with enabling it. This is my vaules.yaml fo…

Please create Docker images and host it in your container registry. I’d recommend against copying it at runtime using initcontainers or sidecars. With Go plugins, all you need is to set the correct environment variable KONG_PLUGINS in this case to include your plugin name: env: plugins: bundled,…

This bums me out… I don’t really want to build a custom container just to add a single file (mostly because i don’t want to spin up the accompanying ci/cd and then host that container in some registry). Is there anything wrong with loading the golang library file similar to how we mount the lua file…

[image] thatbenguy: Is there anything wrong with loading the golang library file similar to how we mount the lua files via configmaps into the container??? One needs to compile go and then put that inside the container. This feature is like pealing an onion so we decided to not add in. I do …

Yeah, i think the issue of also needing to compile the go pluginserver adds an additional layer of complexity which complicates the “just using configmaps” method that the lua plugins use. I will continue to tinker around, but I suspect you are right, and the best way is just to make a custom contai…

my attempt at creating a docker-file and adding my plugin: FROM golang:1.14.0 as go-builder # Build golang plugin(s) WORKDIR /build COPY ./custom-go-plugins ./ WORKDIR /build/go-hello/src RUN go get -insecure ./... RUN go build -buildmode=plugin . # Build golang pdk RUN go get github.com/Kong/go-…

@thatbenguy , Note that your go-builder stage uses a Debian base image, while kong:2.0 is based on Alpine – as such, the binary you generate isn’t valid for the target system and you get that error message. Try using golang:1.14.0-alpine as Go builder and please let us know how it goes!

Well spotted @salazar ! That fixed my issue with the pluginserver. I do think i hit another issue with using both lua plugins and golang plugins side-by-side waiting for db Error: /usr/local/share/lua/5.1/kong/cmd/start.lua:64: 2020/05/13 23:31:06 failed to open plugin go-hello: plugin: not impleme…

Ah, ok, i figured it out. I was building the plugins without CGO, since in order to have cgo i had to apk add build-base and I assumed I didn’t need it… A few people belly-aching about it here: https://github.com/docker-library/golang/issues/153 Since go’s plugin package requires C functions, witho…

[image] thatbenguy: _helpers.tpl I am trying to follow your docker file only. Trying with go-hello plugin . Able to start the kong successfully, but while executing the plugin, getting error. Follwing are the logs - kong_1 | 2020/08/26 18:12:33 [crit] 26#0: *368 connect() to unix:…
