Description of the issue

"Port Already Allocated" Error Hinders Database Container Local Installation Progress.

Reason for the issue

Database container docker image already occupies port 5432, Resulting in a "Port Already Allocated" Error During Local database Installation.

Ideas of solution

Port Mapping Adjustment:

Advantages:

• Quick and straightforward solution.
• Minimal adjustments to the current setup.

Disadvantages:

• Not suitable if both containers need the same port.
• Risk of conflicts with other services when using common ports.

docker run -p "5433:5432" -v "$(pwd)/oeplatform_data:/var/lib/postgresql/data" ghcr.io/openenergyplatform/oeplatform-postgres:latest

Workflow checklist

• I am aware of the workflow in CONTRIBUTING.md

There have been added some updates to the docker setup. You can check again if you want. Ince you pull the latest docker image you also have to delete the data directory in the oeplatform/docker/ as otherwise it will attempt to use the content from the previous database setup.
