Docker Gets Ignore, Auto-Pauses Containers On Commit
Docker 1.1.0 was recently released, within a month of the 1.0 release, with several features such as .dockerignore, pausing of containers when a commit is made to them, tailing logs and several other improvements.
Some notable features and changes -
- .dockerignore allows you to ignore certain files and directories when sending the files to the daemon
- docker commit now automatically pauses the container to which the commit is being made (can be disabled). This is a convenience feature, since committing to running containers was not recommended in any case.
- Can tail logs of a container to get last x lines of a log
- Can add tar file as context for "docker build"
- Can bind-mount entire file system (/) to a container
There are also several performance, API and other minor improvements. For a complete list, have a look at the release announcement.
