Docker Image Tag Generator
Generates an example Docker image tag in a realistic format — version tags, environment tags, and commit-SHA-style tags — for documentation or config examples.
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
- Press generate for an example Docker image tag.
Common use cases
- Documentation examples
- Placeholder CI/CD config
- Teaching image-tagging conventions
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.
Entries are chosen with your browser's cryptographic random number generator, so every entry on the list is equally likely. How Generate Random works.
