## Release Notes
|
||||||
|
|
||||||
|
<b>Version 1.1.0</b>
|
||||||
|
|
||||||
|
### New Features
|
||||||
|
|
||||||
|
*`.dockerignore` support*
|
||||||
|
|
||||||
|
You can now add a `.dockerignore` file next to your `Dockerfile` and Docker will ignore files and directories specified in that file when sending the build context to the daemon.
|
||||||
|
Example: https://github.com/dotcloud/docker/blob/master/.dockerignore
|
||||||
|
|
||||||
|
*Pause containers during commit*
|
||||||
|
|
||||||
|
Doing a commit on a running container was not recommended because you could end up with files in an inconsistent state (for example, if they were being written during the commit). Containers are now paused when a commit is made to them.
|
||||||
|
You can disable this feature by doing a `docker commit --pause=false <container_id>`
|
||||||
|
|
||||||
|
*Tailing logs*
|
||||||
|
|
||||||
|
You can now tail the logs of a container. For example, you can get the last ten lines of a log by using `docker logs --tail 10 <container_id>`. You can also follow the logs of a container without having to read the whole log file with `docker logs --tail 0 -f <container_id>`.
|
||||||
|
|
||||||
|
*Allow a tar file as context for docker build*
|
||||||
|
|
||||||
|
You can now pass a tar archive to `docker build` as context. This can be used to automate docker builds, for example: `cat context.tar | docker build -` or `docker run builder_image | docker build -`
|
||||||
|
|
||||||
|
*Bind mounting your whole filesystem in a container*
|
||||||
|
|
||||||
|
`/` is now allowed as source of `--volumes`. This means you can bind-mount your whole system in a container if you need to. For example: `docker run -v /:/my_host ubuntu:ro ls /my_host`. However, it is now forbidden to mount to /.
|
||||||
|
|
||||||
|
|
||||||
|
### Other Improvements & Changes
|
||||||
|
|
||||||
|
* Port allocation has been improved. In the previous release, Docker could prevent you from starting a container with previously allocated ports which seemed to be in use when in fact they were not. This has been fixed.
|
||||||
|
|
||||||
|
* A bug in `docker save` was introduced in the last release. The `docker save` command could produce images with invalid metadata. The command now produces images with correct metadata.
|
||||||
|
|
||||||
|
* Running `docker inspect` in a container now returns which containers it is linked to.
|
||||||
|
|
||||||
|
* Parsing of the `docker commit` flag has improved validation, to better prevent you from committing an image with a name such as `-m`. Image names with dashes in them potentially conflict with command line flags.
|
||||||
|
|
||||||
|
* The API now has Improved status codes for `start` and `stop`. Trying to start a running container will now return a 304 error.
|
||||||
|
|
||||||
|
* Performance has been improved overall. Starting the daemon is faster than in previous releases. The daemon’s performance has also been improved when it is working with large numbers of images and containers.
|
||||||
|
|
||||||
|
* Fixed an issue with white-spaces and multi-lines in Dockerfiles.
