Introduction
In this lab, you will be transported back to the ancient Roman arena, where Docker containers battle for supremacy in the virtual world. You are cast as an eager spectator, with the goal of understanding and mastering the art of managing Docker containers. As you witness the thrilling Docker battles, your task is to learn how to control and manipulate the Docker system for various scenarios.
Exploring Docker
In this step, you will embark on an exploration of Docker by pulling and running a simple container.
- Pull the "hello-world" Docker image:
docker pull hello-world
- Run the "hello-world" container:
docker run hello-world
Creating Your Own Container
In this step, you will create a simple Dockerfile to build your own custom Docker image.
Create a file named Dockerfile in the ~/project directory with the following content:
FROM alpine:latest
CMD ["echo", "Welcome to the Docker Arena"]
Build the Docker image from the Dockerfile:
docker build -t docker-arena .
Run the custom Docker container based on the newly-built image:
docker run docker-arena
Managing Containers
In this step, you will learn how to start, stop, and remove Docker containers.
- Start a container named "nginx" using the official nginx image:
docker run --name nginx -d -p 8080:80 nginx
- Stop the running "nginx" container:
docker stop nginx
- Remove the "nginx" container:
docker rm nginx
