x509.certificate_managed can write an error message into the cert file instead of failing

[farcaller]

Description of Issue/Question

x509.certificate_managed will corrupt the pem file and then will die with exception.

Setup

Set up x509.certificate_managed for a signing policy that doesn't exist

Steps to Reproduce Issue

Run the state. The generated cert file will contain a single line, e.g.: Signing policy saltca does not exist. instead on pem data.

Additionally, the state will now fail forever with:

@farcaller can you please share a sanitized version of sls file when running into this issue?

[nvx]

I've run into the same issue. Seems to occur when someone makes a mistake in the pillar top.sls that makes pillar rendering error out - when this happens instead of aborting it nukes the already existing file with "Signing policy mypolicy does not exist."

mycert:
  x509.certificate_managed:
    - name: /etc/mycert.pem
    - ca_server: server.example.com
    - signing_policy: mypolicy
    - public_key: /etc/mycert.key
    - managed_private_key:
        name: /etc/mycert.key
        bits: 2048
        backup: True
