»legacy_isotime Function

The legacy_isotime function returns the current date and time using the given format string. The format string follows golang's datetime formatting. See isotime-function-format-reference for more details.

This function has been provided to create backwards compatibility with Packer's legacy JSON templates. However, we recommend that you upgrade your HCL Packer template to use timestamp and formatdate together as soon as is convenient.

Note: If you are using a large number of builders, provisioners or post-processors, the isotime may be slightly different for each one because it is from when the plugin is launched not the initial Packer process. In order to avoid this and make the timestamp consistent across all plugins, set it as a user variable and then access the user variable within your plugins.
