I think that any guides you find for Gitea + Renovate should work still for Forgejo + Renovate.
I believe the process is:
- Create Forgejo instance
- Create a user for Renovate within Forgejo
- Using the CLI on your local machine (or another tool to complete this step), create an SSH public/private key for the Renovate user
- Log into Forgejo using the Renovate user and configure the previously created SSH keys and separately generate a Forgejo token
- Create a Renovate instance with settings for at least
RENOVATE_GIT_PRIVATE_KEY
(SSH private key value),RENOVATE_TOKEN
(Forgejo token value),RENOVATE_PLATFORM
(gitea
),RENOVATE_ENDPOINT
(Forgejo API base URL), and any other Renovate settings that you may find helpful/necessary to configure (eg:GITHUB_COM_TOKEN
,RENOVATE_AUTODISCOVER
, etc.) - Depending on how you want things to work, you may need to give the Renovate Forgejo user access to individual repos
