Hello hachemsfar,

Lenses Box includes both Kafka, Kafka Connect, and Schema Registry, so you don’t have to setup a separate container for Kafka Connect.

Try to mount your connector plugins under `/connectors` inside Lenses Box, then once everything’s up, you can create new connectors via Lenses.

E.g:

```auto
version: '3'
services:   
  lenses:
    image: lensesio/box:latest
    container_name: lenses
    ports:
      - "3030:3030"
      - "9092:9092"
    environment:
      ADV_HOST : 127.0.0.1
      EULA: https://licenses.lenses.io/d/?id=KEY
    volumes: 
        - "./connectors

```

That’s all!
