fileexists Function

fileexists determines whether a file exists at a given path.

fileexists(path)

Functions are evaluated during configuration parsing rather than at apply time, so this function can only be used with files that are already present on disk before Packer takes any actions.

This function works only with regular files. If used with a directory, FIFO, or other special mode, it will return an error.

Examples

> fileexists("${path.folder}/hello.txt")
true

fileexists("custom-section.sh") ? file("custom-section.sh") : local.default_content
