Oracle is pleased to announce the release of Oracle Container Runtime for Docker version 18.09. Oracle Container Runtime allows you to create and distribute applications across Oracle Linux systems and other operating systems that support Docker. Oracle Container Runtime for Docker consists of the Docker Engine, which packages and runs the applications, and integrates with the Docker Hub, Docker Store and Oracle Container Registry to share the applications in a Software-as-a-Service (SaaS) cloud.
- Oracle has implemented multi-registry support that makes it possible to run the daemon with the --default-registry flag, which can be used to change the default registry to point to a registry other than the standard Docker Hub registry. More flexibility is provided with the --add-registry option which defines alternate registries to be used in case the default registry is not available. Other functionality available in this feature includes the --block-registry flag which can be used to prevent access to a particular Docker registry. Registry lists help ensure that images are prefixed with their source registry automatically, so that a listing of Docker images indicates the source registry from which an image was pulled.
- This release of Docker introduces an integrated SSH connection helper that allows a Docker client to connect to a remote Docker engine securely over SSH.
- The Docker client application can now be installed as an independent package, docker-cli, so that the Docker engine daemon does not need to be installed on a system that may be used to manage a remote Docker daemon instance.
- Docker 18.09 uses a new version of containerd, version 1.2.0. This version of containerd includes many enhancements for greater compatibility with the most recent Kubernetes release.
- This release has integrated additional improvements and security fixes, including the fix to CVE-2019-5736.
