ad response from Docker engine

To get a response from the Docker engine, you can use the Docker client command-line interface (CLI) or the Docker API. Here are a few examples:

1. Using Docker CLI: Open your terminal and run the following command to get a response from the Docker engine:

   docker <command>

Replace `<command>` with the desired Docker command, such as `docker ps` to list running containers or `docker images` to list available images. The output will be displayed in the terminal.

2. Using Docker API: You can also interact with the Docker engine programmatically by making HTTP requests to the Docker API. Here's an example using curl in a command-line interface:

   curl -X GET --unix-socket /var/run/docker.sock http:/v1.40/<endpoint>

Replace `<endpoint>` with the desired Docker API endpoint, such as `/containers/json` to get a list of containers. The response will be returned in JSON format.

Remember to adjust the version number (`v1.40`) and socket path (`/var/run/docker.sock`) based on your Docker setup.
