Run Dockerfile

If you want to run a container using a Dockerfile, you'll need to follow these steps

Steps to Run a Container from a Dockerfile

  1. Create a Dockerfile
  2. Navigate to the directory where you want to create the Dockerfile: bash cd /opt/docker/
  3. Create a new file named Dockerfile: bash nano Dockerfile:
  4. Add the following content to the Dockerfile: dockerfile FROM httpd:latest COPY . /usr/local/apache2/htdocs EXPOSE 80

  5. Save and exit.

  6. Build the Docker Image

  7. Run the following command to build the image: bash docker build -t my-httpd .

  8. Run the Container

  9. Start the container with the required parameters: bash docker run -d --name httpd -p 3003:80 -v /opt/finance:/usr/local/apache2/htdocs my-httpd

  10. This command:

    • Runs the container in detached mode (-d).
    • Names the container httpd.
    • Maps port 3003 on the host to 80 inside the container.
    • Mounts the /opt/finance directory from the host to /usr/local/apache2/htdocs inside the container.

  11. Verify the Container is Running

  12. Check the running containers: bash docker ps
  13. Ensure that port mapping is correct: bash docker inspect httpd | grep -i "3003"

Now your httpd container should be up and running based on the Dockerfile! Let me know if you need any modifications or troubleshooting assistance.
