This summary provides an overview of deploying a PHP application that communicates with a Couchbase NoSQL container using Docker and Docker Compose. The project structure includes two containers: one for the PHP application and another for the Couchbase server, each with its own Dockerfile and configuration files. The PHP application uses environment variables to connect to the Couchbase cluster, while the Couchbase server is automatically provisioned using a script in the Dockerfile. The docker-compose.yml file defines the services and their dependencies, including port mappings and environment variables. The containers are deployed using the `docker-compose run` command, which builds and deploys each image with the defined ports and configuration.
