Docker Hub Image Tracker

Track Docker Hub images: pull counts, tags, size, architecture support, vulnerability scan status, official images, stars, and update frequency. Search images by keyword or fetch specific repositories. Returns tag history, layer count, and platform support.

Features

• Image stats: pull count, star count, official/automated status, last updated
• Tag details: tag name, digest, size, OS, architecture, last pushed timestamp
• Search: find images by keyword, optionally filtered to official images only
• Batch processing: track multiple images in parallel with concurrency control
• 404 handling: gracefully skips images that do not exist

Input

Field	Type	Description	Default
images	string[]	Docker image names to track	—
searchKeyword	string	Keyword to search Docker Hub	—
maxSearchResults	integer	Max images from search (1–100)	25
includeTags	boolean	Fetch latest 10 tags per image	true
officialOnly	boolean	Filter to official Docker images only	false

Image name formats accepted:

• nginx — official library image
• python:3.12 — tag is stripped, latest data fetched
• grafana/grafana — organization image
• myorg/myrepo:tag — tag stripped, namespace/name used

At least one of images or searchKeyword must be provided.

Output

Each record contains:

{
  "namespace": "library",
  "name": "nginx",
  "full_name": "library/nginx",
  "description": "Official build of Nginx.",
  "is_official": true,
  "is_automated": false,
  "pull_count": 1000000000,
  "star_count": 20000,
  "last_updated": "2024-11-01T10:00:00Z",
  "content_types": ["image"],
  "media_types": ["application/vnd.docker.distribution.manifest.v2+json"],
  "top_tags": [
    {
      "name": "latest",
      "digest": "sha256:abc123...",
      "last_pushed": "2024-11-01T10:00:00Z",

Usage Examples

Track specific images

{
  "images": ["nginx", "redis", "python:3.12", "grafana/grafana"],
  "includeTags": true
}

Search for database images

{
  "searchKeyword": "postgresql",
  "maxSearchResults": 10,
  "includeTags": false
}

Official images only

{
  "searchKeyword": "python",
  "officialOnly": true,
  "maxSearchResults": 5,
  "includeTags": true
}

Combined: specific images + search

{
  "images": ["nginx", "redis"],
  "searchKeyword": "monitoring",
  "maxSearchResults": 5,
  "includeTags": true
}

Pricing

• $0.002 per image analyzed (Pay-Per-Event)
• No authentication required — uses public Docker Hub API
• No proxy needed

Notes

• Official library images use library as the namespace (e.g. library/nginx)
• Tags returned are the 10 most recently pushed, sorted by Docker Hub's default order
• Rate limits: Docker Hub public API allows generous usage without authentication
• The Actor runs without any API keys or tokens required
