💡 Why This Matters

🌍 Real World

Docker inspect is used daily by developers and system admins to check container settings, network info, and troubleshoot issues.

💼 Career

Knowing how to inspect containers helps in debugging, monitoring, and managing containerized applications in DevOps roles.

1

Create a Docker container named my_nginx

Run the command to create and start a Docker container named my_nginx using the nginx image in detached mode.

Docker

# Run the docker command to create and start the container
# Your code here

Need a hint?

Use docker run -d --name my_nginx nginx to start the container in the background.

2

Use docker inspect to get detailed info about my_nginx

Run the command docker inspect my_nginx to get detailed JSON information about the container named my_nginx.

Docker

docker run -d --name my_nginx nginx
# Run docker inspect on my_nginx
# Your code here

Need a hint?

Use docker inspect my_nginx to see detailed info about the container.

3

Extract the container's IP address from the inspect output

Use docker inspect with the --format option and Go template '{{range .NetworkSettings.Networks}}{{.IPAddress}}{{end}}' to extract and display the IP address of the my_nginx container.

Docker

docker run -d --name my_nginx nginx
docker inspect my_nginx
# Extract and display the IP address of my_nginx
# Your code here

Need a hint?

Use docker inspect --format='{{range .NetworkSettings.Networks}}{{.IPAddress}}{{end}}' my_nginx to get the IP address.

4

Display the IP address of the my_nginx container

Run the command to display only the IP address of the my_nginx container using docker inspect with the correct format option.

Docker

docker run -d --name my_nginx nginx
docker inspect my_nginx
docker inspect --format='{{range .NetworkSettings.Networks}}{{.IPAddress}}{{end}}' my_nginx
# Display the IP address
# Your code here

Need a hint?

The IP address usually starts with 172. or 192. depending on your Docker network.
