Pack your application into Docker container

Here is the short plan we follow:

1. Initial assessment: Assess the current web application architecture and resource requirements.
2. Dockerization strategy: Develop a strategy for containerizing the web application using Docker.
3. Dockerfile creation: Create Dockerfiles for each component of the web application.
4. Docker image building: Build Docker images using the Dockerfiles.
5. Image registry setup: Set up a Docker image registry for storing and managing the Docker images.
6. Testing and validation: Conduct thorough testing of the Dockerized web application images.
7. Image deployment: Deploy the Dockerized web application images to the desired environment.
8. Monitoring and logging: Set up monitoring and logging for the Dockerized web application containers.
9. Documentation and training: Provide documentation and training on managing and maintaining the Dockerized web application containers.
10. Post-conversion support: Offer ongoing support for the Dockerized web application containers.

Note: This is a high-level outline, and the specific details of each step may vary depending on your web application requirements.
