A python app needed to be Dockerized, and then it needs to be deployed on App Server 3. We have already copied a requirements.txt file (having the app dependencies) under /python_app/src/ directory on App Server 3. Further complete this task as per details mentioned below:
Create a Dockerfile under /python_app directory:
Use any python image as the base image. Install the dependencies using requirements.txt file. Expose the port 8087. Run the server.py script using CMD.
Build an image named nautilus/python-app using this Dockerfile.
Once image is built, create a container named pythonapp_nautilus:
Map port 8087 of the container to the host port 8099.
Once deployed, you can test the app using curl command on App Server 3.
- Access App Server 3 via SSH
- Switch to root user:
sudo su - Create Dockerfile: Dockerfile
- Build image:
docker build -t nautilus/python-app . - Run the container:
docker run -p 8099:8087 --name pythonapp_nautilus -d nautilus/python-app - Check the result:
curl http://localhost:8099
