Re: [openstack-dev] [Higgins][Zun] Project roadmap
I think there's a weird cycle in plugging into nova too... Say the cloud has no native container support added except for Zun. The container api Zun provides could be mapped to a Zun plugin that: 1. nova boot --image centos --user-data 'yum install -y docker; yum start docker; ' 2. starts the container that was requested on that docker supporting vm. So if you add a flavor to nova to map to a container, and you accept a flavor to Zun to launch containers on, you have to know to filter out the flavors that might come right back to Zun so you don't get into an infinite loop of nested docker instances.

Re: [openstack-dev] [Higgins][Zun] Project roadmap
Hi all, it looks like Glare may cover some (or all) your use cases. To understand the functionality proposed to Glare I suggest you to read this: https://review.openstack.org/#/c/283136/. It would be cool if Glare supports everything you need. If you need something else please add a comment, we will try to consider your requirements. You can also contact me(kairat), Mike Fedosin (mfedosin) and Nikhil Komawar (nikhil) for any questions related to Glare.

This support is very minimalistic in nature, since it doesn't do anything beyond just storing a docker FS tar ball. I think it was felt that, further support for docker FS was needed. While there were suggestions of private docker registry, having something in band (w.r.t openstack) maybe desirable.

The maturity of the project is also a concern, but we will revisit it later. * Leverage Glance for storing container images. If necessary, contribute to Glance for missing features (i.e. support layer of container images). * Support enforcing multi-tenancy by doing the following: ** Add configurable options for scheduler to enforce neighboring containers belonging to the same tenant. What about have the scheduler pluggable instead of having a lot of configuration options? [Hongbin Lu] For short-term, no. We will implement a very simple scheduler to start. For long-term, we will wait for the scheduler-as-a-service project: https://wiki.openstack.org/wiki/Gantt . I believe Gantt will have a pluggable architecture so that your requirement will be satisfied. If not, we will revisit it. ** Support hypervisor-based container runtimes. Is that hyper.sh?

Will it have ordering primitives, i.e. this container won't start until this one is up and running. ? I also wonder whether the Higgins container abstraction will have rich status reporting that can be used in ordering. For example, whether it can differentiate started containers from those that are already listening in their exposed ports. [Hongbin Lu] I am open to that, but needs to discuss the idea further.

This support is very minimalistic in nature, since it doesn't do anything beyond just storing a docker FS tar ball. I think it was felt that, further support for docker FS was needed.

I also wonder whether the Higgins container abstraction will have rich status reporting that can be used in ordering. For example, whether it can differentiate started containers from those that are already listening in their exposed ports. > > > NOTE: I might forgot and mis-understood something.

[openstack-dev] [Higgins][Zun] Project roadmap
Hi team, During the team meetings these weeks, we collaborated the initial project roadmap. I summarized it as below. Please review. * Implement a common container abstraction for different container runtimes. The initial implementation will focus on supporting basic container operations (i.e. CRUD). * Focus on non-nested containers use cases (running containers on physical hosts), and revisit nested containers use cases (running containers on VMs) later. * Provide two set of APIs to access containers: The Nova APIs and the Zun-native APIs. In particular, the Zun-native APIs will expose full container capabilities, and Nova APIs will expose capabilities that are shared between containers and VMs. * Leverage Neutron (via Kuryr) for container networking. * Leverage Cinder for container data volume. * Leverage Glance for storing container images. If necessary, contribute to Glance for missing features (i.e. support layer of container images). * Support enforcing multi-tenancy by doing the following: ** Add configurable options for scheduler to enforce neighboring containers belonging to the same tenant. ** Support hypervisor-based container runtimes. The following topics have been discussed, but the team cannot reach consensus on including them into the short-term project scope.
