Inspect Container​

View detailed information about a container.

$ docker inspect container_id

✅ Docker Compose​

Docker Compose is a tool for defining and running multi-container Docker applications.

Create and Start Services​

Docker networks allow containers to communicate with each other.

Create a Network​

Create a custom network.

$ docker network create network_name

List Networks​

View a list of available networks.

$ docker network ls

Attach a Container to a Network​

Connect a container to a custom network.

$ docker network connect network_name container_name

✅ Dockerfile​

Build a Docker image using a Dockerfile.

$ docker build -t image_name:tag .

✅ Additional Docker Commands​

Logs​
