  • [x] Provide sensible logger output for TTY and non-TTY formats
  • [x] Separate commands to list logs & general status[^2]

[^1]: Unlike in Terraform HCL, values must not contain arithmetic expressions (e.g. 60*60*24 is not valid, but 86400 is valid). Also, declaring multiple resource blocks produces undefined behavior; i.e. defined behavior, but too contrived to explain in a footnote; definitely not what users expect. [^2]: With a special case for $parallelism > 1$ where users can filter logs for a single task.

after a "Provide sensible logger output for TTY and non-TTY formats" I think an attach type command would be helpful to "live" monitor a task.

Part of “Separate commands to list logs & general status” to my mind. It could be log --follow or similar?

Closing in favor of https://github.com/iterative/terraform-provider-iterative/issues/666, which holds the remaining items 😈
