Kubernetes and Docker Pattern popualate two image tables - Known Error

Kubernetes and Docker Pattern popualate two image tables Description The customer would like to understand the model and when Docker and Kubernetes patterns populate cmdb_ci_docker_image and cmdb_ci_docker_local_image tables.

Steps to Reproduce

Build a docker image from the source code Do not push it to any registry to avoid calculating manifest digest Run Docker discovery Docker Pattern will populate cmdb_ci_docker_local_image table Now push the same image to the local registry Run Docker Pattern again Discovery will populate cmdb_ci_docker_image due to defined manifest Kubernetes images always contain manifest digests so they will be always added to cmdb_ci_docker_image table Workaround The diagram below presents the model which covers images created by Docker and Kubernetes patterns.

Images used by Kubernetes Pods will be always added to cmdb_ci_docker_image table because image digests will be caclualted at the image registry push automatically. Kubernetes doesn't use local images because local images would have to be built at every Kubernetes cluster node.

On the other hand the Docker target image table depends on digests.

In the example below 2 images (myimage/unused/alpine, myimage/alpine) will be added to cmdb_ci_docker_local_image. Others will be added to cmdb_ci_docker_image.

$ docker image ls --digests --format '{{.ID}},{{.Repository}},{{.Digest}}' 3297c4272e3b,127.0.0.1:5000/naveen,sha256:8ce582e708ddfa8af8b18d0b4ec6fca28f2f0a90dfd84d28a6d07c7badb430f0 a8781fe3b7a2,registry,sha256:f4e1b878d4bc40a1f65532d68c94dcfbab56aa8cba1f00e355a206e7f6cc9111 d684d659b474,myimage/unused/alpine, d1397258b209,redis,sha256:e647cfe134bf5e8e74e620f66346f93418acfc240b71dd85640325cb7cd01402 e92fd48047fd,almalinux/9-base,sha256:ba3f7aeb14a07548098888a931243c4e8a911218e8d4e33443cdaabfd2635ee1 c30ffba6de49,almalinux,sha256:b353d3bd6c1b5142d943d88a8c5d452ba11687ecd68015b8f7829ac8ae456e2f 731c8b73370e,192.168.1.219:5000/mybusybox,sha256:e6c7f1eb0cea914a503424a79de7f5117d8cbd771c114213d474ceb99933b6b4 ba5dc23f65d4,busybox,sha256:478209e7be50e5f5c9fd47a6a71d43c119dd44c393160e49dc4bb86f99a439de 3e5d6b89cabf,busybox,sha256:97e3873d1f61ba651b632e4755fc52e1d90c9f6e4f01d9b720f37af5efed17e5 7b338cab6d90,myimage/alpine, 1c10e9375739,busybox,sha256:72010e07a9a0a6517cfa3262ec00cedccd994315b1a1f3ac07bdd42bfdb79bab
