🐳 Docker Hub Tags Scraper

🚀 Export public Docker Hub repository tags in seconds. Size, digest, architecture, OS, and per-manifest layer metadata.

🕒 Last updated: 2026-06-05 · 📊 16 fields per record · Any public repo · Multi-arch aware · No login required

The Docker Hub Tags Scraper turns the public hub.docker.com/v2/repositories/{namespace}/{name}/tags endpoint into a clean dataset. It paginates the full tag list of any public repository, flattens each tag's multi-architecture manifest, and lets you filter by name, architecture, or operating system.

Use it to track image release cadence, audit container supply chains, or pull a quick snapshot of which architectures a base image supports.

🎯 Target Audience	💡 Primary Use Cases
🛡️ Container security teams	Audit which tags ship which digests
🚀 DevOps engineers	Track upstream image releases
🏗️ Platform teams	Validate multi-arch coverage for base images
📊 Cloud cost teams	Map image sizes across tags
🧪 Researchers	Study how popular images evolve over time
👩‍💻 Developers	Find the right tag for a new dependency

📋 What the Docker Hub Tags Scraper does

• Paginates https://hub.docker.com/v2/repositories/{repo}/tags with the public unauthenticated API.
• Flattens the per-tag images array so each row carries a primary architecture, OS, and digest.
• Keeps the full per-manifest array as a nested field for multi-arch analysis.
• Filters by tag name substring, architecture, or OS at the scraper level.
• Surfaces upstream HTTP failures as a single diagnostic record.
• Exports to every Apify dataset format.

💡 Why it matters: Docker Hub's REST endpoint is public but its multi-arch shape is awkward. This actor flattens it so you can answer questions like "which arm64 tags shipped this week" with a SQL query.

⚙️ Input

Field	Type	Required	Description
repository	string	No	`namespace/name`. Use `library/` for official images.
maxItems	integer	No	Free 10. Paid up to 1,000,000.
ordering	enum	No	Sort order. Defaults to most recently updated.
nameContains	string	No	Tag-name substring filter.
architecture	enum	No	Keep only manifests for the chosen architecture.
osFilter	enum	No	Keep only manifests for the chosen OS.

Example 1. Latest nginx tags.

{ "repository": "library/nginx", "maxItems": 50 }

Example 2. arm64-only postgres tags.

{ "repository": "library/postgres", "architecture": "arm64", "maxItems": 100 }

⚠️ Good to Know: Anonymous calls to Docker Hub are rate-limited per IP. The actor automatically respects pagination.
