Caddy UI server

➡️ Server responsible to serve the Caddy UI and communicate with the Caddy server API

Please refer to the caddy-ui repository for end-user instructions.

Architecture

This server is stateless and does the following:

• Serve the built static files of the frontend to the user
• Act as an intermediary proxy to communicate with your Caddy server (to work around CORS)

It is written in Go in order to have a small static binary on a Docker Scratch image.

Repository

The repository contains:

• the HTTP API server written in Go
• the web frontend app written in ReactJS, as the ui Git submodule

Setup

1. Use the following command:

   docker run -d -p 8000:8000/tcp qmcgaw/caddy-ui

   You can also use docker-compose.yml with:

   docker-compose up -d

2. You can update the image with docker pull qmcgaw/caddy-ui or use one of tags available

Development

1. Setup your environment

   Using VSCode and Docker (easier)

   1. Install Docker
      • On Windows, share a drive with Docker Desktop and have the project on that partition
      • On OSX, share your project directory with Docker Desktop
   2. With Visual Studio Code, install the remote containers extension
   3. In Visual Studio Code, press on F1 and select Remote-Containers: Open Folder in Container...
   4. Your dev environment is ready to go!... and it's running in a container 👍 So you can discard it and update it easily!

   Locally

   1. Install Go, Docker and Git

   2. Install Go dependencies with

      go mod download

   3. Install golangci-lint

   4. You might want to use an editor such as Visual Studio Code with the Go extension. Working settings are already in .vscode/settings.json.

2. Commands available:

   # Build the binary
   go build cmd/app/main.go
   # Test the code
   go test ./...
   # Lint the code
   golangci-lint run
   # Build the Docker image
   docker build -o build ui
   docker build -t qmcgaw/caddy-ui .
   # Run the container
   docker run -it --rm -p 8000:8000/tcp qmcgaw/caddy-ui
