[Bug 1660385] Re: Alert user of Ec2 Datasource on lookalike cloud
Wow, sorry for being delinquent in seeing these. Simon, Vladimir, Nick,
and David, thank you for your input.
Cloud-init is making this change with the goal of improvement both in
performance and in user experience (such as attempting http traffic to a
firewalled-off 169.254.169.254 and timing out).
I think your concerns mainly fall into a few different buckets.
a.) (Simon) configuration of: datasource_list: [ Ec2, None ]
This should be working correctly now. If cloud-init sees only one entry (or
one entry and 'None') then it will just select that datasource and go on. If
it is not doing this, please file a bug and we'll get that fixed. Your
'reboot' issue is a result of the Ec2 and Openstack metadata services having a
different instance-id, so cloud-init sees this as a new instance.
b.) RDO provisioned Openstack nova systems were not correctly identifed.
This is fixed under bug 1675349. RDO provisioned nova systems changed
the product_name exposed through smbios to be 'OpenStack Compute' rather
than what upstream has ('OpenStack Nova').
c.) Non AWS desired use of EC2 metadata service.
This can be fixed in one of 2 ways
1.) file a bug, tell me how to identify your platform, and we'll make
cloud-init identify it as legitimate use of Ec2 metadata. I did this
for brightbox at bug 1661693. Please collect some information on
the system like an example qemu command line, and the output of
sudo sh -c 'cd /sys/class/dmi/id && grep -r . *'
Nick, David, this speaks directly to you. I'm perfectly willing to
support your cloud, just tell me how to identify it.
2.) change your launching to make the system look like it *is* in AWS.
http://docs.aws.amazon.com/AWSEC2/latest/UserGuide/identify_ec2_instances.html
. My comment #2 in bug 1661693 shows how to do this in libvirt or qemu.
3.) cloud-init offer another supported way to re-use EC2 metadata service.
cloud-init will have to identify this *somehow* so you'll likely have
to change your qemu/libvirt invocation, but
Vladimir, your idea of NoCloud change here is a good one, and I'm open to
that. I've opened bug 1691772 to address that.
Please feel free to reach out to me in Freenode IRC (smoser in #cloud-init).

[Bug 1660385] Re: Alert user of Ec2 Datasource on lookalike cloud
We are in the same situation as quite a few others have mentioned here in the bug report already. To echo Nick (n6ck)'s comment above, we are also running a EC2 compatible metadata server here as well. Although we fully expect to add our own cloud-init datasource provider, it would be nice to know if the EC2 "strict_id: false" work-around will be here to stay for a while. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1660385 Title: Alert user of Ec2 Datasource on lookalike cloud To manage notifications about this bug go to: https://bugs.launchpad.net/cloud-init/+bug/1660385/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
[Bug 1660385] Re: Alert user of Ec2 Datasource on lookalike cloud
This is also a pretty big issue for us, as we are also running a EC2 compatible metadata server for us. Currently we can suppress the warnings, but it looks like in Ubuntu 16.10 there will be even a timeout included. Is there any option which we can set to stay with the current behaviour (no timeout, no warning, just use EC2 metadata service)? -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1660385 Title: Alert user of Ec2 Datasource on lookalike cloud To manage notifications about this bug go to: https://bugs.launchpad.net/cloud-init/+bug/1660385/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
[Bug 1660385] Re: Alert user of Ec2 Datasource on lookalike cloud
This is a pretty big issue for those of us not running inside any cloud environment, but still relying on non-intrusive ways to provision VMs. I know that NoCloud is the expected datasource for that, but Ec2 was always a hassle-free option. It is trivial to spin up a Ec2-compatible metadata server, and then the only thing you need is to boot a vanilla ubuntu image with no strings attached, it will find ec2 metadata and will just work. Compare this to NoCloud: - pass a kernel command line option, which requires to boot qemu with custom kernel outside of ubuntu guest image and is troublesome or - add config files into the guest's /var/lib/cloud/seed/nocloud, which requires mounting the image on the host and tinkering with it (and as soon as it's mounted, there's little reason to use cloud-init at all, TBH) or - add a virtual cd image with cloud metadata, which requires provisioning those images and some (at times) non-trivial bookkeeping, e.g. when you migrate a vm to a different host (two machines are still a NoCloud). If you are going this route, I would highly suggest you to consider an option where NoCloud can be pointed at network server via, e.g. dmi strings, that are trivially configurable from qemu / libvirt. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1660385 Title: Alert user of Ec2 Datasource on lookalike cloud To manage notifications about this bug go to: https://bugs.launchpad.net/cloud-init/+bug/1660385/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs

Can you consider disabling them for OpenStack clouds?

[Bug 1660385] Re: Alert user of Ec2 Datasource on lookalike cloud
Following up on my last comment: I now understand why cloud-init on our Ubuntu OpenStack images tries to use EC2 metadata rather than OpenStack metadata; the diskimage-builder (DIB) tool puts the following in /etc/cloud/cloud.cfg.d/91-dib-cloud-init-datasource.cfg: datasource_list: [ Ec2, None ] When I add "OpenStack, " in front of that list and reboot, then the warning message disappears (but the datasource change also causes the SSH host key to change, which is a bit annoying). I'll raise this with the upstream diskimage-builder project. I assume that they prefer the EC2 datastore for a reason, so I'll suggest to add the configuration with the "strict_id: false" attribute to the generated images. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1660385 Title: Alert user of Ec2 Datasource on lookalike cloud To manage notifications about this bug go to: https://bugs.launchpad.net/cloud-init/+bug/1660385/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
[Bug 1660385] Re: Alert user of Ec2 Datasource on lookalike cloud
This "bug fix" is a huge regression for me. We run an OpenStack-based cloud and provide (among others) Ubuntu-based images on it, which we regularly refresh. Since the latest refresh, our users get these warnings on every login. The warnings are completely unwarranted, and I don't understand the reasoning behind them: Like most OpenStack clouds, we do provide EC2 metadata over HTTP on the well-known link-local address 169.254.169.254. We also provide metadata in OpenStack's own format, also via 169.254.169.254. Instances can detect that they are running on OpenStack based on DMI values. Now cloud-init is trying to be clever about which kind of cloud it is running on, and use suitable metadata depending on that. So far, so good! On our cloud it should be able to detect (via DMI) that it is running on OpenStack. The reasoning explained in the bug description suggests that cloud-init only wants to use EC2 metadata when running on EC2. (I think it could also use EC2 metadata under OpenStack, but be that as it may.) But shouldn't cloud-init then just use the OpenStack metadata service (which we also provide)? Complaining that the EC2 metadata service exists as well seems pointless to me. Can someone explain the logic of the current behavior under OpenStack to me? Because I don't understand it. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1660385 Title: Alert user of Ec2 Datasource on lookalike cloud To manage notifications about this bug go to: https://bugs.launchpad.net/cloud-init/+bug/1660385/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs

[Bug 1660385] Re: Alert user of Ec2 Datasource on lookalike cloud
** Description changed: + === Begin SRU Template === + [Impact] + Opportunistic polling of the Ec2 Metadata service, which lives at + 169.254.169.254 can be problematic for numerous reasons including timeouts. + + In this first phase of SRU, the code that has been added will be set to + a warn-only mode. + + In 16.04, if cloud-init finds it is using a EC2 Metadata Service but + not running on Amazon AWS, it will warn the user. + + In 16.10, it will warn the user and sleep 10 seconds to increase the + likelyhood of being noticed. + + [Test Case] + TBD + + [Regression Potential] + There is real regression potential here. That is why we have announced + this fairly widely and also are putting this into place with warnings + only first. + + After some time is passed, further SRUs will put more strict behavior + in place. + + [Other Info] + We've announced this fairly widely on mailing lists + https://lists.ubuntu.com/archives/ubuntu-devel/2017-February/039697.html + === End SRU Template === + + Many cloud providers mimic the EC2 Metadata service [1] in order to provide a level of EC2 compatibility for images.
