Daniel, Dao Quang Minh d7bbe2fcb5 document dirperm1 fix for #783 in known issues 
Since `dirperm1` requires a more recent aufs patch than many current OS release,
we cant remove #783 completely. This documents that docker will apply `dirperm1`
automatically for systems that support it

Version 1.5.0

(2015-02-03)

For a complete list of patches, fixes, and other improvements, see the merge PR on GitHub.

New Features

  • [1.6] The Docker daemon will no longer ignore unknown commands while processing a Dockerfile. Instead it will generate an error and halt processing.
  • The Docker daemon has now supports for IPv6 networking between containers and on the docker0 bridge. For more information see the IPv6 networking reference.
  • Docker container filesystems can now be set to--read-only, restricting your container to writing to volumes PR# 10093.
  • A new docker stats CONTAINERID command has been added to allow users to view a continuously updating stream of container resource usage statistics. See the stats command line reference and the container stats API reference. Note: this feature is only enabled for the libcontainer exec-driver at this point.
  • Users can now specify the file to use as the Dockerfile by running docker build -f alternate.dockerfile .. This will allow the definition of multiple Dockerfiles for a single project. See the docker build command reference for more information.
  • The v1 Open Image specification has been created to document the current Docker image format and metadata. Please see the Open Image specification document for more details.
  • This release also includes a number of significant performance improvements in build and image management (PR #9720, PR #8827)
  • The docker inspect command now lists ExecIDs generated for each docker exec process. See PR #9800) for more details.
  • The docker inspect command now shows the number of container restarts when there is a restart policy (PR #9621)
  • This version of Docker is built using Go 1.4

Note: Development history prior to version 1.0 can be found by searching in the Docker GitHub repo.

Known Issues

This section lists significant known issues present in Docker as of release date. It is not exhaustive; it lists only issues with potentially significant impact on users. This list will be updated as issues are resolved.

  • Unexpected File Permissions in Containers An idiosyncrasy in AUFS prevents permissions from propagating predictably between upper and lower layers. This can cause issues with accessing private keys, database instances, etc.

For systems that have recent aufs version (i.e., dirperm1 mount option can be set), docker will attempt to fix the issue automatically by mounting the layers with dirperm1 option. More details on dirperm1 option can be found at aufs man page

For complete information and workarounds see Github Issue 783.

  • Docker Hub incompatible with Safari 8 Docker Hub has multiple issues displaying on Safari 8, the default browser for OS X 10.10 (Yosemite). Users should access the hub using a different browser. Most notably, changes in the way Safari handles cookies means that the user is repeatedly logged out. For more information, see the Docker forum post.
