# Containerizing the IGP App with Docker
|
||||
|
||||
## Steps Performed
|
||||
|
||||
### 1. Created a Multi‑Stage Dockerfile (`Dockerfile`)
|
||||
|
||||
Two stages:
|
||||
|
||||
| Stage | Image | Purpose |
|
||||
|---|---|---|
|
||||
| `build` | `mcr.microsoft.com/dotnet/sdk:10.0` | Restores dependencies, builds, and publishes the Blazor WASM app |
|
||||
| `final` | `nginx:alpine` | Copies the published `wwwroot/` output and a custom `nginx.conf` that serves it |
|
||||
|
||||
### 2. Created a Custom nginx Config (`nginx.conf`)
|
||||
|
||||
- Listens on port **8887** (not the default 80) so it doesn't conflict with other containers.
|
||||
- Adds Blazor‑required MIME types: `application/wasm` (`.wasm`), `application/octet-stream` (`.dll`, `.blat`, `.dat`, `.webcil`).
|
||||
- Enables `gzip_static` so pre‑compressed `.gz` variants are served automatically.
|
||||
- Implements SPA fallback: `try_files $uri $uri/ /index.html` for client‑side routing.
|
||||
|
||||
### 3. Built the Image
|
||||
|
||||
```
|
||||
docker build -t igp-app:latest -f Dockerfile .
|
||||
```
|
||||
|
||||
Result: `docker.io/library/igp-app:latest`
|
||||
|
||||
### 4. Ran the Container
|
||||
|
||||
```
|
||||
docker run -d --name igp-app -p 8887:8887 igp-app:latest
|
||||
```
|
||||
|
||||
The container is now serving at **http://localhost:8887**.
|
||||
|
||||
### 5. Verified
|
||||
|
||||
- `docker ps` shows the container `Up` and port mapping `0.0.0.0:8887->8887/tcp`.
|
||||
- `curl http://localhost:8887/` returns HTTP `200`.
|
||||
|
||||
## Files
|
||||
|
||||
| File | Purpose |
|
||||
|---|---|
|
||||
| `Dockerfile` | Multi‑stage build: .NET SDK → publish → nginx |
|
||||
| `nginx.conf` | nginx config with Blazor MIME types, gzip, SPA fallback, port 8887 |
|
||||
|
||||
## How to Stop
|
||||
|
||||
```
|
||||
docker stop igp-app
|
||||
docker rm igp-app
|
||||
```
|
||||
|
||||
## How to Rebuild
|
||||
|
||||
```
|
||||
docker build -t igp-app:latest -f Dockerfile .
|
||||
docker rm -f igp-app
|
||||
docker run -d --name igp-app -p 8887:8887 igp-app:latest
|
||||
```

# Publishing and Serving the IGP App Locally
|
||||
|
||||
## Steps Performed
|
||||
|
||||
### 1. Publish the Blazor WebAssembly App
|
||||
|
||||
Ran `dotnet publish` targeting Release configuration, outputting to `publish_release/`:
|
||||
|
||||
```
|
||||
dotnet publish .\IGP\IGP.csproj -c Release -o .\publish_release
|
||||
```
|
||||
|
||||
This produced a standard Blazor WASM publish layout:
|
||||
- `publish_release/wwwroot/` — static assets (HTML, CSS, JS, WASM, DLLs)
|
||||
- `publish_release/dotnet.js` — .NET runtime loader
|
||||
- `publish_release/web.config` — IIS configuration
|
||||
|
||||
### 2. Serve the Published Files on Port 8777
|
||||
|
||||
Wrote a small Node.js static file server (`serve_publish.cjs`) that:
|
||||
|
||||
- Serves files from `publish_release/wwwroot/`
|
||||
- Maps correct MIME types for `.wasm` ( `application/wasm` ), `.dll` ( `application/octet-stream` ), `.js` ( `application/javascript` ), `.br`, `.gz`
|
||||
- Implements SPA fallback: non-file routes serve `index.html` so Blazor's client-side routing works on refresh
|
||||
|
||||
```
|
||||
node serve_publish.cjs
|
||||
```
|
||||
|
||||
Server is now running at **http://localhost:8777**.
|
||||
|
||||
### 3. Verify
|
||||
|
||||
- `netstat -ano | findstr ":8777"` confirms the process is LISTENING
|
||||
- `curl -s -o NUL -w "%{http_code}" http://localhost:8777/` returns `200`
|
||||
|
||||
## How to Stop
|
||||
|
||||
Find the process and kill it:
|
||||
|
||||
```
|
||||
netstat -ano | findstr ":8777.*LISTENING"
|
||||
Stop-Process -Id <PID>
|
||||
```
|
||||
|
||||
## Files
|
||||
|
||||
| File | Purpose |
|
||||
|---|---|
|
||||
| `publish_release/wwwroot/` | Published static output |
|
||||
| `serve_publish.cjs` | Simple Node.js HTTP server with Blazor MIME support |
