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 ๐ฅ, ๐ฅ and ๐ฅ.
NOTE: The cert-manager maintainers can decide to change the criteria and number of tiers at any time.
๐ฅ Tier (Production-ready)
- 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:
- a short explanation on how to install cert-manager (including the used version and a link to https://cert-manager.io/docs/installation/)
- all required steps to install the issuer
- an explanation on how to configure the issuer's Custom Resources
- an explanation on how to issue a certificate using the issuer (using a Certificate resource)
๐ฅ Tier (Maintained)
- The issuer has had a release in the last 12 months (at the time of checking all issuers2).
๐ฅ Tier (Unmaintained)
