Description Yuxin Sun 2023-07-13 06:52:48 UTC

Description of problem:
Suggest to install NetworkManager-cloud-setup package, enable Azure configuration and enable nm-cloud-setup.timer and nm-cloud-setup.service. This service can detect the secondary IPs from Azure metadata and configure it inside the VM.

Version-Release number of selected component (if applicable):
RHEL-8/9 RHEL images in the Azure Marketplace
* NetworkManager-nm-cloud-setup version must larger than NetworkManager-1.30.0-13.el8_4, or will hit a critical issue, see BZ#2014510

How reproducible:
100%

Steps to Reproduce:

Actual Results:
There's no NetworkManager-cloud-setup installed in the RHEL images

Expected Results:
1. Install NetworkManager-cloud-setup package
2. mkdir -p /etc/systemd/system/nm-cloud-setup.service.d
cat > /etc/systemd/system/nm-cloud-setup.service.d/10-enable-azure.conf << EOF
[Service]
Environment=NM_CLOUD_SETUP_AZURE=yes
EOF
3. Enable nm-cloud-setup.service, nm-cloud-setup.timer

Additional info:
It has been enabled in the AWS RHEL images. Suggest to also enable it in the Azure images.

> 2. There's "Environment=NM_CLOUD_SETUP_AZURE=yes" in /usr/lib/systemd/system/nm-cloud-setup.service

Files in /usr/lib are provided by the RPM package. It's not good to modify them.
Instead, systemd supports overlaying configuration in /etc.

See "EXAMPLE SETUP FOR CONFIGURING AND PREDEPLOYING NM-CLOUD-SETUP" in `man nm-cloud-setup` for how to enable nm-cloud-setup.

Thank you so much Thomas!

According to 'man nm-cloud-setup', the step 2 should be:

mkdir -p /etc/systemd/system/nm-cloud-setup.service.d
cat > /etc/systemd/system/nm-cloud-setup.service.d/10-enable-azure.conf << EOF
[Service]
Environment=NM_CLOUD_SETUP_AZURE=yes
EOF

I'll correct my step in the comment 0. Thanks!
