| *** openstack changes topic to "Roll Call (Meeting topic: zun)" | 02:59 | |
| hongbin | i knew kevin is on vacation today | 03:00 |
| fengshengqin | we may have a short meeting | 03:00 |
| hongbin | sure | 03:00 |
| fengshengqin | #topic Blueprints | 03:00 |
| *** openstack changes topic to "Blueprints (Meeting topic: zun)" | 03:00 | |
| fengshengqin | 1. OpenStack as a virtual Kubernetes node (assignee: kevinz) | 03:01 |
| fengshengqin | #link https://blueprints.launchpad.net/zun/+spec/zun-connector-for-k8s | 03:01 |
| fengshengqin | let's skip it | 03:01 |
| fengshengqin | 2. Introduce quota for containers (assignee: TBD) | 03:01 |
| fengshengqin | #link https://blueprints.launchpad.net/zun/+spec/quota-support | 03:01 |
| hongbin | this one is assigned to kien | 03:01 |
| hongbin | it looks kien is not here | 03:01 |
| hongbin | so we can skip this as well :) | 03:01 |
| fengshengqin | 3. Manage the reverse disk for container images (assignee: fengshengqin) | 03:02 |
| fengshengqin | #link https://blueprints.launchpad.net/zun/+spec/manage-container-image-disk | 03:02 |
| fengshengqin | i have some ideas for it | 03:02 |
| hongbin | what ideas? | 03:02 |
| fengshengqin | first,we would reverse disk for container images | 03:03 |
| hongbin | yes | 03:03 |
| fengshengqin | 2. we may get the image disk info by 'docker system df' | 03:03 |
| fengshengqin | 3. check the size of free_disk for loading a new image | 03:04 |
| fengshengqin | 4. update the disk if the images is deleted | 03:04 |
| fengshengqin | 5. as we know, a image may has multilayers. | 03:04 |
| fengshengqin | so if avail_disk < image_size, we may return exception | 03:05 |
| fengshengqin | or parse the layers of image, and check which has loaded, which not. | 03:05 |
| fengshengqin | then we can calculate the size we need | 03:06 |
| fengshengqin | that's all. | 03:06 |
| hongbin | since image are with layers, i don't think you can get the exact disk size that will be taken by the image | 03:06 |
| hongbin | however, you can run the 'df' command again after the image is pulled | 03:07 |
| fengshengqin | i will check "docker system df" | 03:07 |
| hongbin | sure | 03:07 |
| fengshengqin | yes, we can update database by df | 03:08 |
| hongbin | what i am commenting is "if avail_disk < image_size, we may return exception" | 03:08 |
| hongbin | i don't think it is necessary to raise the exception based on the image size | 03:08 |
| hongbin | because it is hard to estimate the size to be taken | 03:09 |
| fengshengqin | i know | 03:09 |
| hongbin | however, this is minor | 03:09 |
| hongbin | for this one, i think we can do this step by step | 03:10 |
| fengshengqin | we may add a congifure to choose | 03:10 |
| hongbin | which config? | 03:10 |
| fengshengqin | whether need to parse mutil layers | 03:11 |
| hongbin | i think it will be hard to parse | 03:11 |
| hongbin | anyway | 03:11 |
| hongbin | a question though | 03:12 |
| fengshengqin | yes, i will think about it more | 03:12 |
| hongbin | if the disk is not enough, how about deleting some image? | 03:12 |
| hongbin | you can do "docker images" to check which image is not used | 03:13 |
| fengshengqin | no,we may choose other host to create container | 03:13 |
| hongbin | ok | 03:13 |
| fengshengqin | but it is not safe | 03:13 |
| fengshengqin | delete images | 03:13 |
| hongbin | i think you can find which image is unused | 03:14 |
| hongbin | if an image is not used by any container, is it safe to delete ? | 03:14 |
| hongbin | #link https://forums.docker.com/t/command-to-remove-all-unused-images/20/2 | 03:15 |
| fengshengqin | how about adding a task to delete unused images | 03:15 |
| hongbin | yes, it can be a periodic task, that is fine | 03:15 |
| fengshengqin | we can create a new bp | 03:16 |
| hongbin | sure | 03:16 |
| fengshengqin | anything else for this? | 03:17 |
| hongbin | for this image reserve feature, my suggestion is to make the design/implementation as simple as possible | 03:17 |
| fengshengqin | ack | 03:18 |
| hongbin | ok | 03:18 |
| hongbin | nothing else from me, go ahead | 03:18 |
