Safe Editing: Automatically handles quoting for values with spaces.
System Environment Import: Interactively view and import variables from your current system environment into the .env file.
External Editor Integration: Quickly open the .env file in your default editor ($EDITOR).
Automatic Discovery: Finds and edits the .env file in the project root by default, or you can specify a path.

🧹 Docker Cleanup (`dv-docker-cleanup`)

Description: A utility to clean up unused Docker resources like containers, images, networks, and volumes.

Prune stopped containers, unused networks, unused volumes, and dangling/unused images.
Supports dry-run mode (--dry-run).
Force option (-f) to skip confirmation.

🐳 Docker Compose Autoscaler (`docker-autoscale.sh`)

Description: Utility to automatically scale a Docker Compose service up or down based on resource utilization. It can run as a sidecar container and monitor the target service or on the host.

Note: A Go-based version of this tool is available in docker/go-scale/.

Scales based on CPU, Memory, or a combination of both.
Flexible Scaling Logic:
- cpu: Scale based on average CPU usage.
- mem: Scale based on average Memory usage.
- any: Scale up if either CPU or Memory is high, but only scale down if both are low.
Fine-Grained Control:
- Set min/max replica counts.
- Configure CPU and Memory thresholds for scaling up and down.
- Define cooldown periods to prevent thrashing.
- Specify the number of instances to add during scale-up (--scale-up-step).
- Require multiple consecutive checks before scaling down to ensure stability (--scale-down-checks).
Robust and Informative:
- Automatically detects and uses docker compose (v2) or docker-compose (v1).
- Includes a --dry-run mode to test your configuration without making changes.
- Provides an initial grace period to allow services to stabilize on startup.
- Logs detailed status, scaling decisions, and heartbeats.

Example Usage

Here is a typical docker-compose.yml setup for using the autoscaler as a sidecar container.

# docker-compose.yml
services:
  # This is the sample application we want to autoscale.
  # It has CPU limits to make it easier to stress and trigger scaling.
  webapp:
    image: nginx:alpine
    deploy:
      resources:
        limits:
          cpus: '0.5'
          memory: 128M

  # This service runs the autoscaler script.
  autoscaler:
    image: iamdanielv/utils:autoscale # Or build from source
    volumes:
      # Required to interact with the Docker daemon on the host
      - /var/run/docker.sock:/var/run/docker.sock
      # Mount the compose file so the script can find the service to validate it
      - ./docker-compose.yml:/app/docker-compose.yml
    command:
      - "--service"
      - "webapp"
      - "--min"
      - "1"
      - "--max"
      - "10"
      - "--metric"
      - "cpu"
      - "--cpu-up"
      - "20" # Scale up when avg CPU > 20%
      - "--cpu-down"
      - "5"  # Scale down when avg CPU < 5%
      - "--poll"
      - "5"  # Check metrics every 5 seconds
      - "--initial-grace-period"
      - "15" # Wait 15s on startup before first check
      # - "--dry-run" # Uncomment to test without making changes
    environment:
      # This ensures the compose command inside the container targets the correct project
      - COMPOSE_PROJECT_NAME=${PROJECT_NAME}

To run this example:

Save the content above as docker-compose.yml.
Run PROJECT_NAME=$(basename "$PWD") docker compose up.
The autoscaler will start with one webapp instance.
To trigger a scale-up, you can generate load. For example, using hey or ab:
```
# Install hey: sudo apt install hey
hey -z 1m http://localhost:8080
```
Watch the logs from the autoscaler container to see it detect the high CPU usage and scale the webapp service up to the --max limit. When the load test finishes, it will eventually scale back down.

🗓️ Docker Compose Scheduler (`docker/schedule/scheduler.py`)

Description: A Python-based scheduler that runs one-off tasks from your docker-compose.yml file based on a schedule. It discovers services to run by reading Docker labels.

Cron Scheduling: Run tasks using standard cron expressions (e.g., * * * * *).
Interval Scheduling: Run tasks at a fixed interval (e.g., every 60 seconds).
Simple Setup: Define your tasks as regular services in docker-compose.yml, add a scheduler.cron or scheduler.interval label, and use a profiles: ["donotstart"] to prevent them from running automatically.
Live Log Streaming: The scheduler captures and streams the logs from each task run in real-time, prefixed with the service name for clarity.

Docker Compose Scheduler - Example Usage

Here is a docker-compose.yml that defines the scheduler and two sample tasks: one running every 10 seconds (interval) and another running every minute (cron).

# docker-compose.yml
services:
  # This service runs the scheduler script.
  scheduler:
    image: iamdanielv/utils:scheduler # Or build from source
    volumes:
      # Required to interact with the Docker daemon on the host
      - /var/run/docker.sock:/var/run/docker.sock
      # Mount this compose file so the scheduler can read the labels
      - ./docker-compose.yml:/app/docker-compose.yml:ro
    command:
      - "--project-name"
      - "${PROJECT_NAME}" # Pass the project name to the script
    environment:
      # This ensures the compose command inside the container targets the correct project
      - PROJECT_NAME=${PROJECT_NAME}

  # An example task that runs every 10 seconds.
  task-interval:
    image: alpine:latest
    command: sh -c 'echo "-> Hello from the 10-second interval task! Timestamp: $(date)"'
    labels:
      - "scheduler.interval=10"
    profiles: ["donotstart"] # Prevents this from starting with 'docker compose up'

  # An example task that runs every minute via a cron schedule.
  task-cron:
    image: alpine:latest
    command: sh -c 'echo "-> Hello from the cron task! Timestamp: $(date)"'
    labels:
      - "scheduler.cron=* * * * *"
    profiles: ["donotstart"] # Prevents this from starting with 'docker compose up'

To run this example:

Save the content above as docker-compose.yml.
Run PROJECT_NAME=$(basename "$PWD") docker compose up scheduler.
Watch the logs from the scheduler container. You will see it discover the two tasks and start running them based on their defined schedules, streaming their output in real-time.

🌡️ System Temperature Monitor (`temp-monitor.sh`)

Description: Continuously displays temperatures from system thermal sensors.

Color-coded sensor readings (green/yellow/red).
Trend arrows (↑/↓/→) show change against a moving average.
Supports multiple thermal sensors.
Configurable refresh interval (-i), temperature delta (-d), and averaging count (-a).

🧑‍🤝‍🧑 User Check (`user-check.sh`)

Description: Ensures the script is running as a specific user, attempting to switch with sudo if not.

Automatically switches to target user with sudo -u.

🎲 Random String Generator (`random-string.sh`)

Description: Generates one or more random hexadecimal strings with configurable:

Number of strings to generate (-n, default: 3).
Length of each string (-l, default: 5).

🎨 Color Palette Viewer (`colors.sh`)

Description: A utility to display all 256 terminal colors for both foreground and background.

Helps in choosing colors for shell scripts and TUIs.
Can display colors as numbers or solid blocks (-b flag).
Supports foreground (-g fg) and background (-g bg) modes.

🖥️ VM Manager (`dv-vm-manager`)

Description: A TUI (Text User Interface) for managing KVM/QEMU virtual machines using virsh.

Dashboard: View real-time status, CPU usage, and memory usage of all VMs.
Controls: Start, shutdown, reboot, or force stop VMs.
