- Multi-stage Docker build: Dockerfile compiles frontend (Node.js) and backend (Gradle) inside Docker; no local Java/Node.js required - Security hardening: replaced full host root mount with specific directory mounts (/proc, /sys, /etc, /var, /home, /opt, /tmp, /srv, /usr) - Host metrics consistency: LinuxMemoryService and CpuDetailsService now read from /host/proc instead of container OSHI - Concurrency: replaced synchronized with AtomicReference in 3 services - Global error handling: added @RestControllerAdvice for JSON error responses - Unit tests: added 32 tests for /proc parsers, CPU usage, process uptime - Docker security: non-root user, read-only FS, no-new-privileges, healthcheck - Debug logging: added log.debug() in silent catch blocks - Documentation: updated README, INSTALLATION, DEVELOPMENT, CONFIGURATION, ARCHITECTURE, CHANGELOG Co-authored-by: Junie <junie@jetbrains.com>

# Installation
|
|
|
|
## Requirements
|
|
|
|
- Docker Engine
|
|
- Docker Compose
|
|
|
|
No local Java or Node.js installation is required — the Dockerfile uses multi-stage build to compile everything inside Docker.
|
|
|
|
## Build and start with Docker Compose
|
|
|
|
From the repository root, run a single command:
|
|
|
|
```bash
|
|
docker compose up -d --build
|
|
```
|
|
|
|
The `--build` flag triggers the multi-stage Docker build that compiles both the Angular frontend and the Spring Boot backend inside Docker. No local JDK or Node.js is needed.
|
|
|
|
The default Compose configuration maps host port `8088` to container port `8080`.
|
|
|
|
Open http://localhost:8088 in your browser.
|
|
|
|
## Alternative: Build the image manually
|
|
|
|
If you prefer to build the Docker image separately:
|
|
|
|
```bash
|
|
docker build -t htop-web .
|
|
docker compose up -d
|
|
```
|
|
|
|
## Alternative: Local Gradle build (requires Java 21 and Node.js)
|
|
|
|
If you need to build locally (for example, to run tests):
|
|
|
|
```bash
|
|
cd backend
|
|
./gradlew clean build
|
|
cd ..
|
|
```
|
|
|
|
The Gradle build also builds the Angular frontend and packages its production assets into the Spring Boot application.
|
|
|
|
## Check status and logs
|
|
|
|
```bash
|
|
docker compose ps
|
|
docker compose logs -f htop-web
|
|
```
|
|
|
|
## Stop the application
|
|
|
|
```bash
|
|
docker compose down
|
|
```
|
|
|
|
## Simple Scenario of using
|
|

|
|
restart: unless-stopped
|
|
pid: host
|
|
read_only: true
|
|
security_opt:
|
|
- no-new-privileges:true
|
|
tmpfs:
|
|
- /tmp:noexec,nosuid,size=64m
|
|
volumes:
|
|
- /proc:/host/proc:ro
|
|
- /sys:/host/sys:ro

|
- /etc/hostname:/host/etc/hostname:ro

|
|
- /usr:/host/usr:ro
