cert-manager

issues public and private SSL certificates using Let's Encrypt and ca-private

This service relies on balena-ca and generates the following structure, placing .ready file in the root of the volume to signal that the volume contains complete set of PKI assets:

/certs
├── {{tld}}-chain.pem -> /certs/private/{{tld}}-chain.pem
├── {{tld}}.key -> /certs/private/{{tld}}.key

The public directory will contain the corresponding LetsEncrypt certificates, if:

  • DNS_TLD does not end with .local (mDNS); and
  • DNS_TLD points to a domain managed by CloudFlare or Gandi; and
  • CLOUDFLARE_API_TOKEN or GANDI_API_TOKEN environment variable is present

In this instance, ${tld}-chain.pem will symlink to public/ instead.
