Use of data sources allows a build to use information defined outside of Packer. See the [`data`](/docs/templates/hcl_templates/datasources) block documentation to learn more about working with data sources. For information on an individual data source, choose it from the sidebar. -> **Note:** Data sources is a feature exclusively available to HCL2 templates included in Packer `v1.7.0` (and newer).
