Docker 1.5.0-rc4 发布，刚发布 Docker 1.5.0 RC3 一天，就又继续发布了 RC4 版本。 二进制包下载： Ubuntu/Debian: https://test.docker.com/ubuntu or curl -sSL https://test.docker.com/ | sh Linux 64bit binary: https://test.docker.com/builds/Linux/x86_64/docker-1.5.0-rc4 Darwin/OSX 64bit client binary: https://test.docker.com/builds/Darwin/x86_64/docker-1.5.0-rc4 Darwin/OSX 32bit client binary: https://test.docker.com/builds/Darwin/i386/docker-1.5.0-rc4 Linux 64bit tgz: https://test.docker.com/builds/Linux/x86_64/docker-1.5.0-rc4.tgz 改进内容： 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 Docker 1.5.0-rc4 发布下载地址
