None - cloud-init 25.1.2 documentation (original) (raw)
Toggle table of contents sidebar
The data source None may be used when no other viable datasource is present on disk. This has two primary use cases:
- Providing user-data to cloud-init from on-disk configuration when no other datasource is present.
- As a fallback for when a datasource is otherwise intermittently unavailable.
When the datasource is None, cloud-init is unable to obtain or render networking configuration. Additionally, when cloud-init completes, a warning is logged that DataSourceNone is being used.
Configuration¶
User-data and meta-data may be passed to cloud-init via system configuration in /etc/cloud/cloud.cfg or/etc/cloud/cloud.cfg.d/*.cfg.
userdata_raw¶
A string containing the user-data (including header) to be used by cloud-init.
metadata¶
The metadata to be used by cloud-init.
Example configuration¶
datasource: None: metadata: local-hostname: "myhost.internal" userdata_raw: | #cloud-config runcmd: - echo 'mydata' > /var/tmp/mydata.txt
