feat: add containerfile and build config

[vhscom]

Summary

This pull request adds a Dockerfile for building and running the OpenRailwayMap project. The Dockerfile includes three stages: setting up PostGIS, building dependencies, and configuring Apache to serve the application. This setup will facilitate a streamlined and consistent development environment.

Changes

• Added a multi-stage Dockerfile:
  • Stage 1: PostGIS Setup
    • Installs PostgreSQL and PostGIS dependencies.
    • Configures PostgreSQL with custom settings.
  • Stage 2: Build Stage
    • Installs necessary build dependencies.
    • Clones the OpenRailwayMap repository and installs Leaflet.
  • Stage 3: Final Stage
    • Installs required runtime packages.
    • Sets up and configures Apache with virtual hosts.
    • Copies the built files and PostgreSQL data from previous stages.
    • Exposes necessary ports and starts services.
• Included Apache virtual host configuration files:
  • www.openrailwaymap.test.conf
  • api.openrailwaymap.test.conf
  • tiles.openrailwaymap.test.conf

Instructions for Running

This can be done using either Podman or Docker. Tested with Podman 4.9.4 during development.

1. Ensure /etc/hosts contains new hostfile entries for .test domain like:

   127.0.0.1   openrailwaymap.test www.openrailwaymap.test
   ::1         openrailwaymap.test www.openrailwaymap.test
   127.0.0.1   a.tiles.openrailwaymap.test b.tiles.openrailwaymap.test c.tiles.openrailwaymap.test
   ::1         a.tiles.openrailwaymap.test b.tiles.openrailwaymap.test c.tiles.openrailwaymap.test
   

2. Build the container image:

   podman build -t openrailwaymap:latest .
   

3. Run the container image:

   docker run -d -p 8080:80 -p 5432:5432 --name openrailwaymap openrailwaymap:latest
   

4. Access the container's shell (if needed for debugging):

   docker exec -it openrailwaymap /bin/bash
   

5. View Apache logs (within the container):

   tail -f /var/log/apache2/error.log /var/log/apache2/access.log
   

Without any further configuration or set-up, the user should be able to access the running application on their local machine (and localhost:8080 will show a default apache site so we know it works).

Tested on Asahi Linux 6.8.9-404.asahi.fc39.aarch64+16k using Podman 4.9.4 on 25 May 2024.

I merged #857 a minute ago. Could you please update your pull request. At least postgis_sfcgal and postgis_topology are not required any more.

Updated postgres setup to accomodate postgis changes and reran locally with success:

podman run -d -p 8080:80 -p 5432:5432 --replace --name openrailwaymap openrailwaymap:latest

Branch updated with squashed changes.
