Working with Docker Volumes

In this Live Environment, you are working on a personal project for a friend who wants to host a website. You have a server running Docker and figure this would be a good use case to containerize the small HTML website. Create a Dockerfile that will use Nginx as the base image and set up two volumes: one volume for the HTML files and the second for logs. Then run the container using the image built from the Dockerfile.

  2. Challenge

    Create a volume for the HTML files

    The following command should be run:

    docker volume create nginx-code
    

    This creates a directory on the lab server: /var/lib/docker/volumes/nginx-code/_data

  3. Challenge

    Create a volume for Nginx logs

    The following command should be run:

    docker volume create nginx-logs
    

    This creates a directory on the lab server: /var/lib/docker/volumes/nginx-logs/_data

  4. Challenge

    Create a Docker Container

    This is the command that should be run:

    docker run -d --name=nextgen-dev -p 80:80 --mount source=nginx-code,target=/usr/share/nginx/html --mount source=nginx-logs,target=/var/log/nginx la/static-site:latest
    

    Use docker ps to show the container.

    Sample output:
