However, neither Trellis (canary version) nor Ansible vault are seeing it.
Confirmed trellis configs: ask_vault_pass: false.
ls -a trellis | grep vault
.vault_pass
I can run without error:
ansible-vault view --vault-password-file .vault_pass trellis/group_vars/all/vault.yml
(Not sure how to manually set the file path using trellis vault. Tried a few different sequences eg trellis vault view -f trellis/group_vars/vault.yml --vault-password-file trellis/.vault_pass).
