Moby v1.5.0 Release Notes

Release Date: 2015-02-10 // over 9 years ago

  • 🏗 Builder

    • 🏗 Dockerfile to use for a given docker build can be specified with the -f flag
    • 🐳 Dockerfile and .dockerignore files can be themselves excluded as part of the .dockerignore file, thus preventing modifications to these files invalidating ADD or COPY instructions cache
    • ➕ ADD and COPY instructions accept relative paths
    • 🐳 Dockerfile FROM scratch instruction is now interpreted as a no-base specifier
    • 👌 Improve performance when exposing a large number of ports

    Hack

    • 👍 Allow client-side only integration tests for Windows
    • 🐳 Include docker-py integration tests against Docker daemon as part of our test suites

    Packaging

    • 👌 Support for the new version of the registry HTTP API
    • 🐳 Speed up docker push for images with a majority of already existing layers
    • 🛠 Fixed contacting a private registry through a proxy

    Remote API

    • 🐳 A new endpoint will stream live container resource metrics and can be accessed with the docker stats command
    • 🐳 Containers can be renamed using the new rename endpoint and the associated docker rename command
    • Container inspect endpoint show the ID of exec commands running in this container
    • 🐳 Container inspect endpoint show the number of times Docker auto-restarted the container
    • New types of event can be streamed by the events endpoint: ‘OOM’ (container died with out of memory), ‘exec_create’, and ‘exec_start'
    • 🛠 Fixed returned string fields which hold numeric characters incorrectly omitting surrounding double quotes

    ⚙ Runtime

    • 🐳 Docker daemon has full IPv6 support
    • 🐳 The docker run command can take the --pid=host flag to use the host PID namespace, which makes it possible for example to debug host processes using containerized debugging tools
    • 🐳 The docker run command can take the --read-only flag to make the container’s root filesystem mounted as readonly, which can be used in combination with volumes to force a container’s processes to only write to locations that will be persisted
    • 🐳 Container total memory usage can be limited for docker run using the --memory-swap flag
    • Major stability improvements for devicemapper storage driver
    • 👍 Better integration with host system: containers will reflect changes to the host's /etc/resolv.conf file when restarted
    • 👍 Better integration with host system: per-container iptable rules are moved to the DOCKER chain
    • 🛠 Fixed container exiting on out of memory to return an invalid exit code

    Other

    • The HTTP_PROXY, HTTPS_PROXY, and NO_PROXY environment variables are properly taken into account by the client when connecting to the Docker daemon
