# Staging (test) certificates

Lets Encrypt puts fairly tight constraints on the number of times you can request a certificate for a given domain (5 per day).

During testing we recommend that you use a Lets Encrypt staging certificate as the limits are much higher.

You can select a staging certificate via the `nginx-le config` command or setting the `PRODUCTION` environment variable to false when creating your docker container.
