VPS with Caddy Reverse Proxy for Multiple Hosted Applications

Runs all docker images for side projects. To setup a new VPS:

1. ssh user@vps_ip_address
2. cd /path/to/project
3. git clone https://github.com/tr3mulant/vps-proxy-multi-site
4. cd vps-proxy-multi-site
5. ./install.sh
   1. Installs required packages for a Ubuntu 22.x VPS instance from a provider like DigitalOcean:
      • ca-certificates
      • curl
      • docker-ce
      • docker-ce-cli
      • containerd.io
      • docker-buildx-plugin
      • docker-compose-plugin
   2. Pulls the images as defined in docker-compose.yml.
      • This requires a .env file with some variables set in order to login to a docker registry of choice with associated credentials.
        • DOCKER_USER
        • DOCKER_PASS
        • DOCKER_REGISTRY
      • Note: the script assumes all images needed in docker-compose.yml are located in the registry pointed to by the DOCKER_REGISTRY env variable.
   3. Once the images are pulled, docker compose builds the containers and starts them

To add a new side project:

1. Build project as a standalone image in the same registry pointed to by DOCKER_REGISTRY in the .env file
2. Add new docker compose definition to docker-compose.yml
3. Commit and push to github repository
4. ssh user@vps_ip_address
5. ./update.sh
   1. Install repository if it does not exist
   2. Pull latest changes from main branch
6. ./reload.sh
   1. Reloads the Caddy reverse proxy
