Secret TLS

To add an SSL Certificate you must create a secret.

Nanocl stores TLS certificate, private-key, certificate-authority, and DH parameter values as PEM contents in CockroachDB. ncproxy writes those values to its runtime directory only when Nginx requires files.

Manual Setup

💡

You can create secrets directly from a deployment Statefile!
But we recommend you to use Secret kind of Statefile and manage them separatly.

There is an Statefile example on how to do it:


ApiVersion: v0.18

You can also load local PEM files with the CLI. Nanocl reads the files before creating the secret, so CockroachDB stores their contents instead of the local paths:


nanocl secret create tls tls.secret \
--certificate-path ./server.crt \
--certificate-key-path ./server.key \
--certificate-client-path ./ca.crt

On the first startup after upgrading to Nanocl 0.18, nanocld converts the legacy database TLS secret from readable filesystem paths to PEM contents. Keep the old files available for that startup. If they will not be available, patch the secret to PEM contents while the 0.17 daemon and files are still accessible, or restore the files before starting 0.18.

Automatic with Let’s Encrypt

You can use certbot to generate a certificate for your domain.
To do so we crafted a generic Statefile for you that can handle the job and create a proper secret.
The secret will be named as follow: cert.{domain_name}.


nanocl state apply -fs nr.next-hat.com/v0.18/certbot -- --email [email protected] --domain deploy-example.com

After the command finished Ssl will be enabled already but you need to update your ProxyRule.
To use the secret for your next deployment:


ApiVersion: v0.18
