How to use these plugins?

[jainrocks]

I didn't install or set any path for go in my Amazon linux instance, where kong is running.
Okay, will check for this.
Thanks a lot @gszr

Hi @jainrocks,

Thanks for posting this question!

Additionally to passing the go_plugins_dir directive (which simply tells the go-pluginserver where to find Go plugins), you need to enable the Go plugin - as with any custom Kong plugin. See this.

So, do something like

go_plugins_dir = /usr/local/kong/goplugins
plugins = bundled,go-hello

Hi @gszr,
Thank you so much for the quick reply. I am getting this:

Kong stopped Error: /usr/local/share/lua/5.1/kong/cmd/start.lua:64: 2020/06/10 15:03:09 stat /usr/local/kong/goplugins/go-hello.so: no such file or directory nginx: [error] init_by_lua error: /usr/local/share/lua/5.1/kong/db/dao/plugins/go.lua:455: bad argument #1 to 'ipairs' (table expected, got nil) stack traceback: [C]: in function 'ipairs' /usr/local/share/lua/5.1/kong/db/dao/plugins/go.lua:455: in function 'get_plugin' /usr/local/share/lua/5.1/kong/db/dao/plugins/go.lua:481: in function 'load_plugin' /usr/local/share/lua/5.1/kong/db/dao/plugins.lua:151: in function 'load_plugin_handler' /usr/local/share/lua/5.1/kong/db/dao/plugins.lua:227: in function 'load_plugin' /usr/local/share/lua/5.1/kong/db/dao/plugins.lua:275: in function 'load_plugin_schemas' /usr/local/share/lua/5.1/kong/init.lua:427: in function 'init' init_by_lua:3: in main chunk
I am new to go language, please help.

@jackkav did you compile the Go plugin? Take a look at the makefile in this repo.

[jainrocks]

@gszr
No I didn't compile earlier. My bad.
I tried compiling now using make
I get:

go build -buildmode=plugin go-hello.go
make: go: Command not found
make: *** [go-hello.so] Error 127

[gszr]

From the error, it looks like you either don't have a Go compiler installed -- or it isn't in the PATH.

@gszr
Still getting the above issue.
After installing the go and setting the path.
go env is gibing the below result
GO111MODULE="" GOARCH="amd64" GOBIN="" GOCACHE="/home/ec2-user/.cache/go-build" GOENV="/home/ec2-user/.config/go/env" GOEXE="" GOFLAGS="" GOHOSTARCH="amd64" GOHOSTOS="linux" GONOPROXY="" GONOSUMDB="" GOOS="linux" GOPATH="/home/ec2-user/go" GOPRIVATE="" GOPROXY="https://proxy.golang.org,direct" GOROOT="/usr/local/go" GOSUMDB="sum.golang.org" GOTMPDIR="" GOTOOLDIR="/usr/local/go/pkg/tool/linux_amd64" GCCGO="gccgo" AR="ar" CC="gcc" CXX="g++" CGO_ENABLED="1" GOMOD="/usr/local/kong/goplugins/go.mod" CGO_CFLAGS="-g -O2" CGO_CPPFLAGS="" CGO_CXXFLAGS="-g -O2" CGO_FFLAGS="-g -O2" CGO_LDFLAGS="-g -O2" PKG_CONFIG="pkg-config" GOGCCFLAGS="-fPIC -m64 -pthread -fmessage-length=0 -fdebug-prefix-map=/tmp/go-build005273170=/tmp/go-build -gno-record-gcc-switches"
But still getting the above issue.

@jainrocks please post the entire output - in the same terminal you ran the go env.

[jainrocks]

@gszr
Below is the output for the same.

[jainrocks]

@gszr Please help here.

[gszr]

@jainrocks note that you are doing sudo make, while the commands before printed the environment for the current user, not root. Try make, without sudo.

Closing this as resolved. Please post an update if you still need help. Thanks!
