Public Cloud Infrastructure Update

The SUSE public cloud update infrastructure in Microsoft Azure Virtual Machines, Amazon EC2, and Google Compute Engine is being improved as of June 1, 2020 including:
  1. Consolidation of update servers to serve all products from the same set of servers
  2. Improved HA setup
  3. Support of traffic routing through the datacenter
Things to know about the new update infrastructure:
  • There will be 3 update servers per region spread across multiple AZ's
  • There is now a marker in instances which will identify it to update servers so that Cloud-Datacenter-Cloud dataflow is supported
  • There will be SLES11 repos but none of them will receive any updates since general support has ended for SLES11
  • VM's must be upgraded to the package "cloud-regionsrv-client" version 9.0.0 or greater
    • zypper up cloud-regionsrv-client
  • IP address access restriction checks of old infrastructure will be disabled no later than end of June, 2020. After this Cloud-Datacenter-Cloud access is open for all regions. This also enables the "bring your own IP" feature in AWS
Instances meet all requirements to use updated infrastructure without modification if both:
  1. Instance is patched up-to-date
  2. Instance image date stamp of 20200526 or greater for anything SLE 12 base in AWS and Azure
If instances do not meet requirements, additional packages will need to be installed.  There are issues that may be encountered depending on instance state and public cloud provider. These are detailed in the Resolution section.


Situation 1: In AWS, there was a way to create private images that would drop the identifier in the metadata that makes an instance from this image a PAYG instance. These instances will not meet requirements to have access to the new update infrastructure. A migration to a new instance will be required to get access to update infrastructure.

Situation 2: In AWS, the marker could be lost if an older image was used. For SLES for SAP images with a date stamp prior to 20181212, there was a bug. This bug was caused by the baseproduct pointing to the wrong product definition file. If a zypper lr is run and no repositories are listed, the fix is:

cd /etc/products.d
rm baseproduct
ln -s baseproduct
systemctl start guestregister.service

Situation 3: In GCE, to access update infrastructure where traffic is routed to the datacenter, all instances must have access to instance metadata for identity tokens. This token is used to validate the identity of the request to SUSE's update infrastructure. Instances must have an associated service account in order to generate this token. This is the default behavior when an instance is launched. However, it is possible to create instances without a service account and therefore without the identity token. For such instances, you will need to stop the instance and add a service account to enable access to SLES update infrastructure.

To check if instance is affected by this situation, run the following on the instance:
curl -H "Metadata-Flavor: Google"

If the metadata returned is not a token and instead a message indicating the following, then instance is affected by this situation and remediation will need to be performed:

{"error":"invalid_request","error_description":"Service account not enabled on this instance"}

To remediate, add a service acount to the instance with no scopes replacing <instance>, <zone> and <service_account>:

gcloud compute instances stop <instance> --zone <zone>
gcloud compute instances set-service-account <instance> --zone <zone> --service account <service_account> --no-scopes
gcloud compute instances start <instance> --zone <zone>

To perform a bulk check for multiple instances, run the following gcloud command to list all instances in the project without a service account:

gcloud compute instances list --filter " = ''"

Situation 4: In Azure, AWS, or GCE, access to repositories went away or are no longer present. This happens because access to the update servers was denied. Update the required packages manually.

All commands executed as root.

The example commands below require the substitution of one or two placeholders:
<arch> is either aarch64 if running ARM based instances or x86_64 if running x86_64 instances.
<slebase> is the base version of the SLES release running, either SLE12 or SLE15. 

For AWS instances:
wget --no-check-certificate<arch>_<slebase>.tar.gz
sha1sum late_instance_offline_update_ec2_<arch>_<slebase>.tar.gz
tar -xf late_instance_offline_update_ec2_<arch>_<slebase>.tar.gz
cd <arch>
zypper --no-refresh --no-remote --non-interactive in *.rpm

For Azure:
wget --no-check-certificate<slebase>.tar.gz
sha1sum late_instance_offline_update_azure_<slebase>.tar.gz
tar -xf late_instance_offline_update_azure_<slebase>.tar.gz
cd x86_64
zypper --no-refresh --no-remote --non-interactive in *.rpm

For GCE:
wget --no-check-certificate<slebase>.tar.gz
sha1sum late_instance_offline_update_gce_<slebase>.tar.gz
tar -xf late_instance_offline_update_gce_<slebase>.tar.gz
cd x86_64
zypper --no-refresh --no-remote --non-interactive in *.rpm

Here are the checksums for the tarballs:

AWS aarch64 SLE15: 250be20f24a941ef27fdb9727a3a4d34fc525ea3 late_instance_offline_update_ec2_aarch64_SLE15.tar.gz

GCE SLE12: 497e2c455696db1ae8e3450a07ac8c74f1674fe5 late_instance_offline_update_gce_SLE12.tar.gz
GCE SLE15: b12ef58ff7575aa5314d1cb393a326c08681174b late_instance_offline_update_gce_SLE15.tar.gz

The tarballs contain the latest released packages of the code that connects an instance to the update infrastructure and the related configuration plus the dependencies.

It is not required to re-register the instance. Once the packages are installed, access to the update infrastructure should be restored by checking the following:

zypper ref

This list of situations will be updated if anything new is reported and verified.  If issues are still occurring after working through these resolutions, work through respective cloud service provider support services.
