# This script is called weekly from /etc/periodic/weekly/croncert.sh

# Duing the weekly check, if certs are renewed,

# If the environment varialbe TESTCERT is defined, this script
|

|
|
# will use --staging --test-cert for obtaining a cert and --dry-run for renewal
|
||
|
|
# This allows the user to test out the configuration and connectivity for obtaining
|
||
|
|
# certs without running into LetsEncrypt limits. It's advisable to define TESTCERT
|
||
|
|
# when initially bringing up the container. Once the logs (docker logs <containername>)
|
||
|
|
# show that LetsEncrypt is working fine, then remove TESTCERT environment variable
|
||
|
|
# to let this script obtain and manage the real certificates
