| lakerzhou | hongbin, I have few questions about the capsule feature. Is the implementation based on docker compose api only? | 17:05 |
| lakerzhou | Hongbin, according to the spec, we are defining something between docker compose and k8ts pods. | 17:07 |
| lakerzhou | Hongbin, docker compose is just a way to run an application consisting of multiple micro-services, which share the yml model, NOT cgroup, not IP address, not even a host., | 17:11 |
| lakerzhou | hongbin, while k8ts pods are quite different. user will not create pod directly. It is managed by k8ts. | 17:14 |
| lakerzhou | hongbin, my concerns are mainly on the networking side for capsule. If it is close to docker compose, we are missing networking fields in yml modeling. | 17:15 |
| lakerzhou | hongbin, if it is similar to k8ts pod, e.g. reside within the same host always, then all the containers in a pod share the same network namespace/drivers. | 17:18 |
| lakerzhou | Hongbin, I need some guidance on the networking consideration for capsule, when we introduce SR-IOV for example. I will move on and focus on container-only SR-IOV support for now. | 17:20 |
| hongbin | lakerzhou: i think you can consider it as a pod from networking perspective | 17:38 |
| hongbin | lakerzhou: that is, all containers inside a capsule share a network namespace | 17:38 |
| lakerzhou | hongbin, it is my understanding of capsule so far. But how to create the individual containers while sharing the same network namespace USING DOCKER is a puzzle to me. | 17:41 |
| hongbin | lakerzhou: the approach we are using right now is to create an infra container, then create a real container that joins the network namespace of the infra container | 17:43 |
| *** sudipto has joined #openstack-zun | 17:45 | |
| *** sudipto_ has joined #openstack-zun | 17:46 | |
| hongbin | lakerzhou: the trick is this option: https://github.com/openstack/zun/blob/master/zun/container/docker/driver.py#L92 | 17:46 |
| lakerzhou | hongbin, according to docker's Container Network Model, there are only three components: Sandbox (network configurations), endpoints(service), network (can be single-host or multi-hosts). | 17:47 |
| lakerzhou | hongbin, sharing the sandbox, meaning sharing network configuration. I agree. | 17:49 |
| hongbin | lakerzhou: i think our definition of sandbox is different from the libnetwork definition of sandbox | 17:49 |
| hongbin | lakerzhou: our definition of sandbox is just an infra container | 17:50 |
| lakerzhou | hongbin, I was referring to the official libnetwork doc: https://github.com/docker/libnetwork/blob/master/docs/design.md | 17:52 |
| hongbin | lakerzhou: then "sandbox" in zun is a "docker container" in their doc | 17:53 |
| lakerzhou | hongbin, the way VM using SR-IOV is to create a SR-IOV port, then attach the port to VM (as nova boot option). I am trying to find the similar option in the container world. | 17:55 |
| hongbin | lakerzhou: ok, let me check | 17:57 |
| lakerzhou | hongbin, I originally thought it is similar to endpoint.join function -- attach an endpoint to a container | 17:57 |
| lakerzhou | hongbin, but now I am not so sure. Nevertheless, endpoint is similar to the neutron port concept to me. | 17:59 |
| hongbin | lakerzhou: not sure if you see this: https://docs.openstack.org/developer/kuryr-libnetwork/devref/libnetwork_remote_driver_design.html | 18:00 |
| *** sudipto_ has quit IRC | 18:01 | |
| *** sudipto has quit IRC | 18:01 | |
| hongbin | lakerzhou: it looks it is similar to endpoint.join | 18:01 |
| lakerzhou | hongbin, if endpoint are the same counterpart in container world, then each endpoint connecting to SRIOV network will consume a VF, e.g. I don't think we can share it in a capsule. I am just trying connect my previous concern back to SR-IOV design. | 18:02 |
| lakerzhou | hongbin, I did not find the link you sent, it is exactly what I wanted to see. Let me read through it. | 18:03 |
| hongbin | lakerzhou: ack | 18:04 |
| *** nicolasbock has quit IRC | 18:04 | |
| *** nicolasbock has joined #openstack-zun | 18:05 | |
| hongbin | lakerzhou: i think yes, if users choose to use capsule instead of an individual container, then they should expect all containers inside a capsule can consume a VF | 18:06 |
| hongbin | brb | 18:07 |
| hongbin | back | 18:12 |
| lakerzhou | hongbin, I agree the goal is to have all containers within a capsule sharing same VF | 18:14 |
| lakerzhou | hongbin, but an endpoint can only attached to one container. | 18:18 |
| hongbin | lakerzhou: yes, which is the infra container | 18:18 |
| hongbin | lakerzhou: only the infra container follows the libnetwork model | 18:18 |
| lakerzhou | hongbin, I see. | 18:19 |
| hongbin | lakerzhou: all containers inside a capsule won't have any endpoint since it simply share the network namespace of the infra container | 18:19 |
| lakerzhou | hongbin, got it. | 18:20 |
| hongbin | ok | 18:21 |
| hongbin | i will talk to kevin later, i think the capsule should have its own API, since it is duplicated with the container API | 18:22 |
| hongbin | my thinking is to have zun-api serve the container API, and have another process (i.e. zun-capsule-api) that serves the capsule API | 18:23 |
| hongbin | hopefully, it will make everything clear to end-users | 18:23 |
| hongbin | eventually, i think capsule can be an optional add-on feature | 18:25 |
| hongbin | lakerzhou: what do you think? | 18:26 |
| hongbin | for sr-iov implementation, i think the implementation for container and capsule should be the same, because capsule is also a container | 18:27 |
| hongbin | (from networking point of view) | 18:28 |
| lakerzhou | hongbin, sorry was away from my desk. I am thinking zun capsule client side only parses the yml and send json to the server. Server will do all the handing. the yml will grow to our single-host orchestration model | 18:29 |
| lakerzhou | hongbin, in the future, we might have a separated multi-host orchestration model build on top of capsule. | 18:30 |
| hongbin | lakerzhou: yes, that could be a direction | 18:31 |
| lakerzhou | hongbin, I got your point. I will assume capsule is a container now, and leave the implementation details of sharing network namespace to capsule. | 18:32 |
| hongbin | lakerzhou: yes, i think that is a right approach | 18:33 |
