*New Features*
|
|
|
|
|
|
2015-02-05 15:23:25 +00:00
|
|
|
* [1.6] The Docker daemon will no longer ignore unknown commands
|
|
|
|
|
while processing a `Dockerfile`. Instead it will generate an error and halt
|
|
|
|
|
processing.
|
2015-02-02 03:35:01 +00:00
|
|
|
* The Docker daemon has now supports for IPv6 networking between containers
|
|
|
|
|
and on the `docker0` bridge. For more information see the
|
|
|
|
|
[IPv6 networking reference](/articles/networking/#ipv6).
|
|
|
|
|
* Docker container filesystems can now be set to`--read-only`, restricting your
|
|
|
|
|
container to writing to volumes [PR# 10093](https://github.com/docker/docker/pull/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
|
2015-02-05 15:23:25 +00:00
|
|
|
[`stats` command line reference](/reference/commandline/cli/#stats) and the
|
2015-02-02 03:35:01 +00:00
|
|
|
[container `stats` API reference](/reference/api/docker_remote_api_v1.17/#get-container-stats-based-on-resource-usage).
|
|
|
|
|
**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
|
|
|
|
|
`Dockerfile`s for a single project. See the [`docker build` command reference](
|
|
|
|
|
/reference/commandline/cli/#build) 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](
|
|
|
|
|
https://github.com/docker/docker/blob/master/image/spec/v1.md) for more details.
|
|
|
|
|
* This release also includes a number of significant performance improvements in
|
|
|
|
|
build and image management ([PR #9720](https://github.com/docker/docker/pull/9720),
|
|
|
|
|
[PR #8827](https://github.com/docker/docker/pull/8827))
|
|
|
|
|
* The `docker inspect` command now lists ExecIDs generated for each `docker exec` process.
|
|
|
|
|
See [PR #9800](https://github.com/docker/docker/pull/9800)) for more details.
|
|
|
|
|
* The `docker inspect` command now shows the number of container restarts when there
|
|
|
|
|
is a restart policy ([PR #9621](https://github.com/docker/docker/pull/9621))
|
|
|
|
|
* This version of Docker is built using Go 1.4

## 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
|
2015-03-26 07:46:13 +00:00
|
|
|
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](http://aufs.sourceforge.net/aufs3/man.html)

|
|
* **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](https://forums.docker.com/t/new-safari-in-yosemite-issue/300).
