From 8f42eb547ddf3202268e1e37a300ba8b2e89cbd2 Mon Sep 17 00:00:00 2001 From: Anh Vo Date: Thu, 5 Aug 2021 15:41:10 -0400 Subject: generate contents for ovf-env.xml when provisioning via IMDS (#959) Azure Linux Agent (WaLinuxAgent) waits for the ovf-env.xml file to be written by cloud-init when cloud-init provisions the VM. This file is written whenever cloud-init reads its contents from the provisioning ISO. With this change, when there is no provisioning ISO, DataSourceAzure will generate the ovf-env.xml file based on the metadata obtained from Azure IMDS. --- cloudinit/sources/DataSourceAzure.py | 15 ++++++++++++++- 1 file changed, 14 insertions(+), 1 deletion(-) (limited to 'cloudinit/sources/DataSourceAzure.py') diff --git a/cloudinit/sources/DataSourceAzure.py b/cloudinit/sources/DataSourceAzure.py index 2e7bfbe3..01e2c959 100755 --- a/cloudinit/sources/DataSourceAzure.py +++ b/cloudinit/sources/DataSourceAzure.py @@ -45,7 +45,8 @@ from cloudinit.sources.helpers.azure import ( is_byte_swapped, dhcp_log_cb, push_log_to_kvp, - report_failure_to_fabric) + report_failure_to_fabric, + build_minimal_ovf) LOG = logging.getLogger(__name__) @@ -540,6 +541,18 @@ class DataSourceAzure(sources.DataSource): ) crawled_data['metadata']['disable_password'] = imds_disable_password # noqa: E501 + if metadata_source == 'IMDS' and not crawled_data['files']: + try: + contents = build_minimal_ovf( + username=imds_username, + hostname=imds_hostname, + disableSshPwd=imds_disable_password) + crawled_data['files'] = {'ovf-env.xml': contents} + except Exception as e: + report_diagnostic_event( + "Failed to construct OVF from IMDS data %s" % e, + logger_func=LOG.debug) + # only use userdata from imds if OVF did not provide custom data # userdata provided by IMDS is always base64 encoded if not userdata_raw: -- cgit v1.2.3
