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