Probably the most interesting new feature that is present in 0.7.0 is the addition of software defined networking or SDN capabilities. Samples of application blueprints using this technique will be available in the 0.7.0 release.
Controller clocker archive#
Usefully, this archive can be automatically generated from the files found in a checkout from the Docker Registry on GitHub. This is achieved by packaging the Dockerfile and associated resources into an archive that can be deployed to a Docker host and used to build an image. Dockerfile SupportĬlocker 0.7.0 also allows the deployment of applications defined solely by Dockerfiles, without requiring the use of specific Brooklyn entities which may not be available. If you have an image pre-configured (such as an AMI) with a set of Docker images, you could also use their IDs when starting an entity, to similar effect. At the moment this is restricted to being shared within a host only, but Clocker 0.8.x will also include the ability to docker push an image out to a remote repository, as well as docker pull from the same or via jFrog’s Artifactory, Docker Hub, quay.io and others.
Controller clocker install#
This means containers for the second and further entities of dome type on a particular Docker host will use that image and customise it, saving the network traffic and install time penalty. With Clocker, after the install phase we execute the docker commit command and save the image data for re-use. tgz archive that is downloaded, or run some APT or Yum commands to set up the environment, which is common to all instances of that type of entity, then customise that for a particular location and launch the service. The normal process in Brooklyn entities is to install them from a. Autogenerating Docker ImagesĬlocker creates the image in the background while it is deploying an entity. The useful thing about Clocker is that this feature is available automatically, for any Brooklyn entity, rather than having to go to the effort of creating new images by hand for each service or application component.
Controller clocker full#
In particular 0.6.2 made full use of the local Docker image repository, in order to take advantage of the fast start-up time that is one of the large benefits of container technology over virtual machines. Version 0.7.0 builds on the previous stable 0.6.2 release, which contained many bugfixes and improvements based on feedback from users, as well as incorporating a few new features such as an affinity strategy and better control of the underlying Docker Engine and containers.
