Docker Image Tag Generator

What you'll get

This generator draws from a hand-checked list of 20 entries. Here is a spread of 6 of them, so you can see the style before you generate:

• myapp:1.4.2
• registry.example.com/team/myapp:2026.07.19
• myapp:main
• myapp:1
• myapp:1.4.2-slim
• myapp:1.4.2-arm64

A fixed sample of the list, not a live draw — your own results are picked at random from all 20, without repeating until the list runs out. Original authoring for Generate Random.. Last reviewed 2026-07-19.

How to use this tool

1. Press generate for an example Docker image tag.

Worked examples

Three of the 20

myapp:1.4.2-alpine, myapp:sha-4a3f9c1 and registry.example.com/team/myapp:2026.07.19 — a version with a base-image suffix, a commit reference, and a dated tag under a private registry path.

Common use cases

• Documentation examples
• Placeholder CI/CD config
• Teaching image-tagging conventions

How this generator works

Each press picks from a fixed list of 20 sample tags with your browser's cryptographic random source. Ask for up to 10 at once and no tag repeats within that press; pressing again is a fresh draw, so a tag can come round again.

Limitations and good to know

• The 20 sample tags illustrate common tagging conventions — semantic version, latest, git-sha style — as patterns to copy; none is pulled from a real registry or image.

Practical tips

• Avoid deploying `latest` to anything you care about — it makes a rollback ambiguous.
• Include the commit reference in the tag so an image can be traced back to the source it was built from.
