Configure with HTTPReq DNS plugin information

In this guide, we will go through the steps neccessary to use the LEGO Operator for providing certificates to another charm using the httpreq dns plugin.

Create a Juju Model:

juju add-model <your model name>

Deploy the Lego charm:

juju deploy lego --channel 4/edge

Configure the charm with your ACME information:

juju config lego \
  server=<your ACME server> \
  email=<your email address> \
  plugin=httpreq

Lego operator accepts all of the environment variables defined in the LEGO documentation as keys in the secret you’ve provided. Provide the configuration for the httpreq as a juju secret:

$ juju add-secret lego-credentials httpreq-endpoint=kgemalmaz.com
secret:crr9g37mp25c77tv2atg
$ juju grant-secret lego-credentials lego
$ juju config lego plugin-config-secret-id=crr9g37mp25c77tv2atg

If the URL is valid, you should see that your charm is now in an active state

Deploy your charm that requires TLS certificates and integrate it with the Lego charm:

juju deploy <your charm>
juju integrate <your charm> lego
