Bug Description

Hi,
I am currently trying DCN for my openstack and when running the deployment command for the edge site i am getting the following error:

FATAL | Pre-fetch all the containers | dcn01-hci-0 | item=172.25.201.68:8787/tripleomaster/openstack-etcd:current-tripleo | error={"ansible_loop_var": "prefetch_image", "changed": false, "msg": "Failed to pull image 172.25.201.68:8787/tripleomaster/openstack-etcd:current-tripleo", "prefetch_image": "172.25.201.68:8787/tripleomaster/openstack-etcd:current-tripleo"}

Can someone please guide me on how to fix this issue?

When i directly run podman pull on the baremetal node:
Trying to pull 172.25.201.68:8787/tripleomaster/openstack-etcd:current-tripleo...
Error: initializing source docker://172.25.201.68:8787/tripleomaster/openstack-etcd:current-tripleo: reading manifest current-tripleo in 172.25.201.68:8787/tripleomaster/openstack-etcd: StatusCode: 404, <!DOCTYPE HTML PUBLIC "-//IETF//DTD HTML 2.0//EN">...

Hey Swogat,

We only download images that are used in the roles during the container image prepare step. So the DCN role isn't one of the defaults, we never would have downloaded the etcd container to the undercloud. In the case of etcd, we only download the image if there is a role using the OS::TripleO::Services:Etcd service:
https://github.com/openstack/tripleo-common/blob/master/container-images/tripleo_containers.yaml.j2#L218-L224

You can pass the `--roles-file` argument to the container image prepare command and specify the roles_data.yaml you're using for dcn:

`openstack tripleo container image prepare -e containers-prepare-parameter.yaml --roles-file roles_data.yaml`

Sounds like you're using undercloud local registry. Can you check if you've the image there tagged appropiately i.e docker://172.25.201.68:8787/tripleomaster/openstack-etcd:current-tripleo ?

I suspect the image won't be there. I notice that https://github.com/openstack/tripleo-heat-templates/blob/master/roles/DistributedComputeHCI.yaml role does not have OS::TripleO::Services::ContainerImagePrepare so the etcd container image required OS::TripleO::Services::CinderVolumeEdge won't be available. Looks like a bug.

You can add OS::TripleO::Services::ContainerImagePrepare to
distributed-roles-data.yaml (your copy of tripleo-heat-templates/roles/DistributedComputeHCI.yaml) and re-deploy the edge stack.

    Add CIP to distributed compute roles

    When running DCN, it's necessary to include the DCN role during the
    container image prepare step. Else the etcd containers will never be
    cached on the undercloud registry. This change adds the
    OS::TripleO::Services::ContainerImagePrepare service to each of the
    distributed compute roles.
