new functions: `parse` and `get` #131

Closed imjasonh closed 6 months ago

imjasonh commented 6 months ago

Provider-defined functions are new in Terraform 1.8+ (and opentofu 1.7+)

This is expected to be a replacement for the oci_string and oci_ref datasources, which perform the same logic, but have their results persisted in state, which adds to slowness.

Usage

output "parsed" {
  value = provider::oci::parse("cgr.dev/chainguard/static@sha256:abc...").digest  # sha256:abcdef...
}

locals {
  parsed = provider::oci::parse("cgr.dev/chainguard/static@sha256:abc...").digest  # sha256:abcdef...
  gotten = provider::oci::get("cgr.dev/chainguard/static").digest  # sha256:...
}
