Docker Engine v27.2.0: Bug Fixes, Packaging Updates, and Known Issues

- CLI: Fix issue with remote contexts over SSH where the CLI would allocate a pseudo-TTY when connecting to the remote host, which causes issues in rare situations. [docker/cli#5351](https://github.com/docker/cli/pull/5351) - Fix an issue that prevented network creation with a `--ip-range` ending on a 64-bit boundary. [moby/moby#48326](https://github.com/moby/moby/pull/48326) - CLI: IPv6 addresses shown by `docker ps` in port bindings are now bracketed. [docker/cli#5365](https://github.com/docker/cli/pull/5365) - containerd image store: Fix early error exit from `docker load` in cases where unpacking the image would fail. [moby/moby#48376](https://github.com/moby/moby/pull/48376) - containerd image store: Fix the previous image not being persisted as dangling after `docker pull`. [moby/moby#48380](https://github.com/moby/moby/pull/48380) #### Packaging updates - Update BuildKit to [v0.15.2](https://github.com/moby/buildkit/releases/tag/v0.15.2). [moby/moby#48341](https://github.com/moby/moby/pull/48341) - Update Compose to [v2.29.2](https://github.com/docker/compose/releases/tag/v2.29.2). [docker/docker-ce-packaging#1050](https://github.com/docker/docker-ce-packaging/pull/1050) - Update containerd to [v1.7.21](https://github.com/containerd/containerd/releases/tag/v1.7.21). [moby/moby#48383](https://github.com/moby/moby/pull/48383), [docker/containerd-packaging#389](https://github.com/docker/containerd-packaging/pull/389) ### Known Issues - There is a known issue when authenticating against a registry in the Docker CLI (`docker login [registry address]`) where, if the provided registry address includes a repository/image name (such as `docker login index.docker.io/docker/welcome-to-docker`), the repository part (`docker/welcome-to-docker`) is not normalized and results in credentials being stored incorrectly, which causes subsequent pulls from the registry (`docker pull index.docker.io/docker/welcome-to-docker`) to not be authenticated. To prevent this, don't include any extraneous suffix in the registry address when running `docker login`. > [!NOTE] > Using `docker login` with an address that includes URL path segments is not a documented use case and is considered unsupported. The recommended usage is to specify only a registry hostname, and optionally a port, as the address for `docker login`. ## 27.1 Release notes for Docker Engine version 27.1 releases. ### 27.1.2 {{< release-date date="2024-08-13" >}} For a full list of pull requests and changes in this release, refer to the relevant GitHub milestones: - [docker/cli, 27.1.2 milestone](https://github.com/docker/cli/issues?q=is%3Aclosed+milestone%3A27.1.2) - [moby/moby, 27.1.2 milestone](https://github.com/moby/moby/issues?q=is%3Aclosed+milestone%3A27.1.2) - Deprecated and removed features, see [Deprecated Features](https://github.com/docker/cli/blob/v27.1.2/docs/deprecated.md). - Changes to the Engine API, see [API version history](https://github.com/moby/moby/blob/v27.1.2/docs/api/version-history.md). #### Bug fixes and enhancements - Fix a regression that could result in a `ResourceExhausted desc = grpc: received message larger than max` error when building from a large Dockerfile. [moby/moby#48245](https://github.com/moby/moby/pull/48245) - CLI: Fix `docker attach` printing a spurious `context cancelled` error message. [docker/cli#5296](https://github.com/docker/cli/pull/5296) - CLI: Fix `docker attach` exiting on `SIGINT` instead of forwarding the signal to the container and waiting for it to exit. [docker/cli#5302](https://github.com/docker/cli/pull/5302) - CLI: Fix `--device-read-bps` and `--device-write-bps` options not taking effect.

This section outlines bug fixes related to CLI, network creation, IPv6 address display, and containerd image store issues in the Docker Engine v27.2.0. It also details packaging updates, including BuildKit v0.15.2, Compose v2.29.2, and containerd v1.7.21. The section also highlights a known issue with the Docker CLI's `docker login` command and how it handles registry addresses, advising against including extraneous suffixes. It then transitions to Docker Engine version 27.1, specifically v27.1.2, listing bug fixes and enhancements for issues such as resource exhaustion, spurious error messages during `docker attach`, incorrect signal handling, and options not taking effect. Packaging updates for v27.1.2 include BuildKit v0.15.1.
