  </code></pre>
  
  <p>So:</p>
  
  <pre><code>$ docker run cp-ksql-cli:5.3.1 http://ksql-server:8088
  </code></pre>
  
  <p>also it:</p>
  
  <pre><code>$ docker run confluentinc/cp-ksql-cli:5.3.1 http://ksql-server:8088
  </code></pre>
  
  <p>and got the error:</p>
  
  <pre><code>Unable to find image 'cp-ksql-cli:5.3.1' locally
  </code></pre>
  
  <p>I'am a new on KSQL and I don't know if this is the correct way to access the CLI. On the google I found this <a href="https://docs.confluent.io/current/ksql/docs/tutorials/basics-docker.html#ksql-quickstart-docker" rel="nofollow noreferrer">tutorial</a> but I can't understanted how enter on the KSQL CLI terminal. Besides that I don't know how it connect with my Kafka broker, zookeper and others..</p>
  
  <p><strong>SOLVED</strong></p>
  
  <p>Accessed using: <code>$ docker-compose exec ksql-cli ksql http://ksql-server:8088</code></p>
