It's time to update Docker Engine

Alpine Linux is a minimalistic operating system base for many Linux container images, known for its efficient packaging, frequent updates, and small image size. On June 15, 2021, Alpine Linux released version 3.14, introducing significant updates that require certain components, such as the musl library, to be updated for proper functionality. The update has prompted software products to migrate their container images to this version due to enhancements in network and security use cases. However, this transition has caused issues in CI/CD environments like GitLab, where outdated Docker Engine versions, specifically those older than 20.10.6, have led to execution problems with Alpine 3.14-based images. To address these issues, users are advised to update their Docker Engine and Docker-in-Docker (dind) images to at least version 20.10.6. While temporary workarounds involve using Alpine 3.13 images, the long-term solution requires planning and executing updates to maintain compatibility with Alpine 3.14 and its dependencies.
