Kong: Error "plugin is in use but not enabled"

[vikaskmr1008]

We are trying to use the hello-world plugin described in this page - https://streamdata.io/blog/developing-an-helloworld-kong-plugin/

We are facing this error in logs:
2017/09/19 09:47:15 [error] 1#0: init_by_lua error: /usr/local/share/lua/5.1/kong.lua:154: hello-world plugin is in use but not enabled
stack traceback:
/usr/local/share/lua/5.1/kong.lua:154: in function 'init'
init_by_lua:3: in main chunk

The Kong version we are using is 0.11.0.

Can someone suggest what could we be missing?

1.vim /usr/local/share/lua/5.1/kong/templates/kong_defaults.lua +8
2.custom_plugins = hello-world 
3.kong restart

[Tieske]

that message means the plugin "hello-world" is in use (eg. there is a reference in the database to it), but it is not enabled (eg. you did not define the custom_plugins configuration property).

do KONG_CUSTOM_PLUGINS=hello-world kong start

I fixed this issue by adding things in custom_plugins and lua_package_path .

Here are the steps to enable and use custom plugin in kong Env.

1 - Add custom plugin name in --- custom_plugins = hello-world

2 - Install hello-world plugin by using following steps ---

If you have source code of your plugin then move into it and execute the command --- "luarocks make"

it will install your plugin.

now you have to execute a command "make install-dev" make sure your plugin have makefile like as --

Once you execute this command "make install-dev". it will create lua file at a location something like that -

/your-plugin-path/lua_modules/share/lua/5.1/kong/plugins/your-plugin-name/?.lua

just copy this path and add it into the kong configuration file in lua_package_path

Something like that --

lua_package_path=/your-plugin-path/lua_modules/share/lua/5.1/kong/plugins/your-plugin-name/?.lua

Now you done your job.

Just start kong -- kong start --vv

You will see that the plugin loaded into kong plugin env.
