On the server that contains the Kong container, use the docker container ls command to get the ID of the Kong container.

docker container ls

Let's say the ID of the Kong container is d937372c09ab9.

CONTAINER ID     IMAGE              COMMAND                 CREATED         STATUS     PORTS     NAMES
d937372c09ab9    kong_kong:2.0.1    "/docker-entrypoin..."  6 minutes ago   Up 13 days 8000-8001/tcp, 8443-8444/tcp

Use the docker exec command to get a shell in the Kong container. You can now issue commands in the container.

docker exec -it <container id> sh
