How can I revert my last push on hub.docker.com?

Question

I have damaged my working docker image by pushing and overwriting by a faulty docker image on hub.docker.com. How can I revert the last push?

Answer 1

There is no revert option that I'm aware of. If you have a good copy of your image somewhere, you can repush that to the registry. To avoid this issue in the future, follow one or more of these steps:

1. Avoid using the latest tag and give each build a unique tag.
2. Use a reproducible build process with a Dockerfile that is saved in version control which uses specific versions for all dependencies. This allows you to checkout a previous state of the Dockerfile to rerun a previous build.
3. Maintain a private registry of your own for your images and any dependencies you have on other images. Make sure to maintain those dependencies (updating periodically) and backup your registry.
