SSL renewals

Comes with a Dockerfile so you can just run that image in your pipelines.

A bit of a very specific case, this allows you to renew Let's Encrypt SSL certs on an Azure App Gateway.

The App gateway needs to have storage account set up as Backend to receive the certbot challenge (./well-known/challenge)

The following environment variables need to be set:

  • DOMAIN
  • MULTI_DOMAIN ('yes' or 'no', if yes, will do www as well)
  • RESOURCE_GROUP
  • GATEWAY_NAME
  • GATEWAY_CERT_NAME
  • EMAIL (for certbot comms)
  • STORAGE_ACCOUNT_NAME
  • USERNAME (service principal)
  • PASSWORD (service principal)
  • TENANT

The following environment variables are optional:

  • EXPIRATION_DAY_LEFT (integer, if this value is less than actual expiration day left of cert, cert renewal will be omitted, default is 30)

Credit mostly to Isaac for this one.
