abspath

abspath(path) converts path to an absolute path. Relative paths are resolved from the playbook’s working directory.

Signature

abspath(path string) string

Example

Ensure that a volume mount path in a Docker run command is always absolute, regardless of where errand is invoked from:

variable "data_dir" {
  description = "Path to the data directory to mount"
  type        = string
  default     = "./data"
}

computed "data_abs" {
  description = "Absolute path to the data directory"
  expression  = abspath(var.data_dir)
}

task "run-db" {
  description = "Start the database with a local volume"
  commands    = ["docker run -v ${computed.data_abs}:/var/lib/postgresql/data postgres:16"]
}

./data becomes something like /home/user/project/data, which is required by docker run.

Notes

abspath resolves the path relative to the effective working directory at evaluation time.
If path is already absolute, it is returned cleaned but otherwise unchanged.
