I wanted to give a quick heads up on some breaking changes that started landing last week with regards to how container images are specified with Heat parameters in TripleO. There are a few patches associated with converting over to the new changes but the primary patches are listed below here [1] and here [2].
Here are a few examples where I'm using a local (insecure) docker registry on 172.19.0.2. The old parameters were: .... DockerNamespaceIsRegistry: true DockerNamespace: 172.19.0.2:8787/tripleoupstream DockerKeystoneImage: centos-binary-keystone:latest ... The new parameters simplify things quite a bit so that each Docker*Image parameter contains the *entire* URL required to pull the docker image. It ends up looking something like this: ... DockerInsecureRegistryAddress: 172.19.0.2:8787/tripleoupstream DockerKeystoneImage: 172.19.0.2:8787/tripleoupstream/centos-binary- keystone:latest ... The benefit of the new format is that it makes it possible to pull images from multiple registries without first staging them to a local docker registry. Also, we've removed the 'tripleoupstream' default container names and now require them to be specified. Removing the default should make it much more explicit that the end user has specified container image names correctly and doesn't accidentally use 'tripleoupstream' by accident because one of the container image parameters didn't get specified. Finally the simplification of the DockerInsecureRegistryAddress parameter into a single setting makes things more clear to the end user as well. A new python-tripleoclient command makes it possible to generate a custom heat environment with defaults for your environment and registry. For the examples above I can run 'overcloud container image prepare' to generate a custom heat environment like this: openstack overcloud container image prepare -- namespace=172.19.0.2:8787/tripleoupstream --env- file=$HOME/containers.yaml We choose not to implement backwards compatibility with the old image formats as almost all of the Heat parameters here are net new in Pike and as such have not yet been released yet. The changes here should make it much easier to manage containers and work with other community docker registries like RDO, etc. [1] http://git.openstack.org/cgit/openstack/tripleo-heat-templates/comm it/?id=e76d84f784d27a7a2d9e5f3a8b019f8254cb4d6c [2] https://review.openstack.org/#/c/479398/17 __________________________________________________________________________ OpenStack Development Mailing List (not for usage questions) Unsubscribe: [email protected]?subject:unsubscribe http://lists.openstack.org/cgi-bin/mailman/listinfo/openstack-dev
