Issuer Tier system

The cert-manager project has a tier system for issuers. This is to help users understand the maturity of the issuer. The tiers are 🥇, 🥈 and 🥉.

NOTE: The cert-manager maintainers can decide to change the criteria and number of tiers at any time.

🥇 Tier (Production-ready)

  • 🥈 Tier criteria.
  • The issuer has an end-to-end tutorial on how to set it up with cert-manager for use in production. At the time of checking1, the used cert-manager version has to be still supported (see Supported Releases). An end-to-end tutorial must include:
    1. a short explanation on how to install cert-manager (including the used version and a link to https://cert-manager.io/docs/installation/)
    2. all required steps to install the issuer
    3. an explanation on how to configure the issuer's Custom Resources
    4. an explanation on how to issue a certificate using the issuer (using a Certificate resource)

🥈 Tier (Maintained)

  • The issuer has had a release in the last 12 months (at the time of checking all issuers2).

🥉 Tier (Unmaintained)
