Is there a way to get certificates from the letsencrypt’s staging environment? See https://letsencrypt.org/docs/staging-environment/
I think what you are looking for is when you create the acme-account secret, you specify the different ACME_SERVER_URL. See below.
create secret generic acme-account --from-literal=ACME_EMAIL=youremailhere --from-literal=ACME_SERVER_URL=https://acme-staging-v02.api.letsencrypt.org/directory

Hope that helps.
I did not try yet, but it seems to be the right solution.
I read the documentation… but not the FAQ! Sorry .
