Installation Guide

RackPeek can run in two ways:

Docker (includes Web UI + CLI)
Native CLI binary

RackPeek stores everything in a writable config/ directory as YAML (including automatic backups). Wherever you run it, that directory must be writable.

Docker (Recommended)

This gives you:

Web UI on port 8080
CLI available inside the container

Docker Compose

version: "3.9"

services:
  rackpeek:
    image: aptacode/rackpeek:latest
    container_name: rackpeek
    ports:
      - "8080:8080"
    volumes:
      - rackpeek-config:/app/config
    restart: unless-stopped
    healthcheck:
      test: ["CMD", "curl", "-fsS", "http://localhost:8080/health"]
      interval: 30s
      timeout: 5s
      start_period: 15s
      retries: 3

volumes:
  rackpeek-config:

Start it:

docker compose up -d

Open:

http://localhost:8080

This uses a named volume, which avoids permission issues and is recommended for most users.

RackPeek stores its ASP.NET DataProtection keys under config/.dataprotection on the same volume, so browser sessions survive container upgrades. If you run the container with a read-only root filesystem, also mount a tmpfs for the app's temp directory:

    read_only: true
    tmpfs:
      - /app/tmp:uid=1654,gid=0

Portainer

Use the same Compose file above in a stack. Portainer typically handles user permissions automatically.

Bind Mount (Advanced)

If you want the YAML stored directly on your host:

volumes:
  - /path/on/host/rackpeek:/app/config

⚠️ The directory must be writable.

If you see:

Access to the path '/app/config/config.yaml' is denied.

Fix ownership:

sudo chown -R 1000:1000 /path/on/host/rackpeek

Or explicitly set the container user:

user: "1000:1000"

RackPeek must be able to:

Create config.yaml
Update it
Write backup files

Permission issues are almost always the cause of startup failures.

Using the CLI (Without Installing It)

If running Docker, you already have the CLI.

Run commands directly inside the container:

docker exec -it rackpeek rpk --help
docker exec -it rackpeek rpk systems list

Native CLI (Linux Only)

If you prefer running RackPeek directly on Linux:

Download

wget https://github.com/Timmoth/RackPeek/releases/download/RackPeek-0.0.3/rackpeek_0_0_3_linux-x64 -O rackpeek

Or:

curl -L https://github.com/Timmoth/RackPeek/releases/download/RackPeek-0.0.3/rackpeek_0_0_3_linux-x64 -o rackpeek

Install

chmod +x rackpeek
sudo mv rackpeek /usr/local/bin/rpk

Create Config Directory

RackPeek expects a config folder next to the binary:

sudo mkdir -p /usr/local/bin/config
sudo touch /usr/local/bin/config/config.yaml

⚠️ It must be writable, since RackPeek writes backups there as well.

If needed:

sudo chown -R $USER:$USER /usr/local/bin/config

Test

rpk --help

Where Your Data Lives

RackPeek stores everything in plain YAML:

config/
└── config.yaml

No database. No telemetry. No lock-in.

You own your data.
