   • local schema, key store, and trust store files referenced in adapters.xml

2. Run the command:

   $ ./build.sh

   which will:

   • create and copy the distribution package to the tmp folder;
   • build the Docker image.

3. Check that the image has been created:

   $ docker image ls kafka-connector-<version>
   
   REPOSITORY                            TAG               IMAGE ID       CREATED          SIZE
   lightstreamer-kafka-connector-0.1.0   latest            f77fc60f7892   13 minutes ago   602MB

4. Launch the container with:

   $ docker run --name kafka-connector -d -p 8080:8080 lightstreamer-kafka-connector-<version>
