Containers - Using ContainerD & Nerdctl

Prerequisites

• containerd
• nerdctl

Assignment

• Lets start by creating a container for running a website in a container using containerd and nerdctl.

1. Create an index.html file for the website.

    mkdir mywebsite
   

2. Add content to the index.html file

    echo "<h1>Welcome to Containers!</h1>" > ./mywebsite/index.html   
   

3. Verify the content of the index.html file

    cat ./mywebsite/index.html
   

4. Create a Dockerfile to create an container

    touch  ./mywebsite/Dockerfile
   

5. Add the below steps in the Dockerfile

    cat <<EOF > ./mywebsite/Dockerfile
    # Use a lightweight web server base image
    FROM nginx:alpine
   
    # Copy the HTML file to the web server's root directory
    COPY index.html /usr/share/nginx/html/index.html
   
    # Expose the web server's port
    EXPOSE 80
    EOF
   

6. Build an image with nerdctl using the Dockerfile

    nerdctl build -t mywebsite-nerd:latest ./mywebsite
   

7. Verify if the images has been created

    nerdctl images
   

8. Run the Container using the image created in the previous step

    nerdctl run -d -p 8081:80 --name container-demo mywebsite-nerd:latest
   

9. Verify if the container is up and running

    nerdctl ps
   

10. Browse the Website using the port 8080

    /mnt/c/Program\ Files/Google/Chrome/Application/chrome.exe http://localhost:8080/
