Hi everyone!

Currently i’m using Docker for running Kong Gateway and add Python Custom plugin. Below is my error part of Docker-compose file and it’s error:

      - KONG_PLUGINS=bundled,demo-plugin
      - KONG_PLUGINSERVER_NAMES=py
      - KONG_PLUGINSERVER_PY_SOCKET=/usr/local/kong/python_pluginserver.sock
      - KONG_PLUGINSERVER_PY_START_CMD=/opt/kong-python-pdk/kong-pluginserver --no-lua-style --plugins-directory /opt/conf/kong-py-plugins
      - KONG_PLUGINSERVER_PY_QUERY_CMD=/opt/kong-python-pdk/kong-pluginserver --no-lua-style --plugins-directory /opt/conf/kong-py-plugins --dump-all-plugins

Anyone who know this problem or develop plugin before please help me.
