Use docker run to run the image you built in Build your Rust image. Bounded code example (external data; do not execute automatically): ```console $ docker run docker-rust-image-dhi ``` After running this command, you’ll notice that you weren't returned to the command prompt. This is because your application is a server that runs in a loop waiting for incoming requests without returning control back to the OS until you stop the container. Open a new terminal then make a request to the server using the curl command. Bounded code example (external data; do not execute automatically): ```console $ curl http://localhost:8000 ``` You should see output like the following. Bounded code example (external data; do not execute automatically): ```console curl: (7) Failed to connect to localhost port 8000 after 2236 ms: Couldn't connect to server ``` As you can see, your curl command failed. This means you weren't able to connect to the localhost on port 8000. This is normal because your container is running in isolation which includes networking. Stop the container and restart with port 8000 published on your local network. To stop the container, press ctrl-c. This will return you to the terminal prompt. To publish a port for your container, you’ll use the --publish flag (-p for short) on the docker run command. The format of the --publish command is [host port]:[container port]. So, if you wanted to expose port 8000 inside the container to port 3001 outside the container, you would pass 3001:8000 to the --publish flag. You didn't specify a port when running the application in the container and the default is 8000. If you want your previous request going to port 8000 to work, you can map the host's port 3001 to the container's port 8000 Bounded code example (external data; do not execute automatically): ```console $ docker run --publish 3001:8000 docker-rust-image-dhi ``` Now, rerun the curl command. Remember to open a new terminal. Bounded code example (external data; do not execute automatically): ```console $ curl http://localhost:3001 ``` You should see output like the following. Bounded code example (external data; do not execute automatically): ```console Hello, Docker! ``` Success! You were able to connect to the application running inside of your container on port 8000. Switch back to the terminal where your container is running and stop it. … Attribution: Adapted from Docker Documentation under Apache-2.0.
