Docker Hub, the world's largest container image repository, has faced controversy due to its recent decision to sunset the free version of Docker Hub. The change would have significantly affected numerous open-source projects and companies relying on it. However, after a public outcry and an apology from Docker, the company has reversed its decision, allowing users to keep their existing organizations without having to switch to paid subscriptions. As a result, the discussion about Docker alternatives continues, with potential workarounds such as hosting images on GitHub's Container Registry or other free registries like GitLab and Quay being explored. Open-source contributors are likely to find alternative solutions to ensure their projects continue working as required.
