Juju Bootstrap - duplicate metadata record for image id

Hi,

I’m trying to bootstrap Juju controller using Ubuntu 22.04, and it looks like it has a problem with image metadata record:

juju --debug bootstrap PhysicalOpenStack JujuController \
--config network=5757cb1a-125f-462d-8e7f-97d958db00cf \
--config ssl-hostname-verification=false \
--config default-base=ubuntu@22.04 \
--config default-series=jammy \
--bootstrap-image=9ac1acac-a2bc-4e78-bf4d-925671ecf170 \
--bootstrap-base=ubuntu@22.04 \
--bootstrap-constraints="allocate-public-ip=false arch=amd64" \
--metadata-source /Users/mk/simplestreams

The problem is that it fails:

Got any ideas what could be the problem?

Hi and welcome @xe0nic!

I’ll try to replicate this on my side, which might take some time since I have to bring up a local openstack environment.

Regarding the image 9ac1acac-a2bc-4e78-bf4d-925671ecf170, so we can win some time, is it a custom ubuntu image that you have on your simplestreams (/Users/mk/simplestreams)? I ask because I’ll try to reproduce using a jammy image.

also, could you please show me the contents of /Users/mk/simplestreams? specially index.json and/or index2.json

This is imported Jammy Cloud Image - here is what I did:

I haven’t been able to replicate this, I’m waiting for an env. In the meantime, what happens if you don’t provide the --bootstrap-image flag? I think juju should still pick the correct image from the provided simplestreams since you are providing the bootstrap series.

Then I have:

12:06:13 DEBUG juju.environs.instances image.go:66 instance constraints {region: RegionOne, base: ubuntu@22.04, arch: amd64, constraints: arch=amd64 mem=3584M allocate-public-ip=false, storage: []}
12:06:13 ERROR juju.cmd.juju.commands bootstrap.go:984 failed to bootstrap model: cannot start bootstrap instance: no metadata for "ubuntu@22.04" images in RegionOne with arch amd64

ok, I got an o7k env up and running and I can indeed reproduce this. I will look a bit more into detail but probably I will open a bug and keep you informed about it.

Bug #2039648 “Error bootstrapping on openstack when specifying b...” : Bugs : Canonical Juju here it is @xe0nic

I’ll try to get on it as soon as possible.

Hi Nicolas,

any updates when it could be resolved?

Hi Marcin!

I started looking at this problem more deeply yesterday, but still don’t have a fix on our side. In the meantime could you please try:

juju --debug bootstrap PhysicalOpenStack JujuController \
--config network=5757cb1a-125f-462d-8e7f-97d958db00cf \
--config ssl-hostname-verification=false \
--config default-base=ubuntu@22.04 \
--config default-series=jammy \
--bootstrap-image=9ac1acac-a2bc-4e78-bf4d-925671ecf170 \
--bootstrap-base=ubuntu@22.04 \
--bootstrap-constraints="allocate-public-ip=false arch=amd64" \

If you can see the imageId on the list when openstack image list then juju should work without --metadata-source, but I want to see if you get any errors (I tried on my instance and it works).

12

It looks like it worked - I have:

Bootstrap complete, controller "jujucontroller" is now available

Thank you
