#!/usr/bin/env sh
# Deployment script for F5 BIGIP
#
# IDNs are currently not supported (Only domain names that follow the [A-Za-z][0-9]()*+,-:;<=>?@[]^_|~. regex are supported)
#
# As ClientSSL profiles do not support * in their names, domain names with wildcards are replaced with a _ character, which can result in a conflict if a domain name similar to _.example.com is used
# however you can set a custom ClientSSL profile name to workaround this issue or use a regular subdomain as CN with wildcard or _ as alternative name
#
# All of the environment variables are optional
# DEPLOY_F5_BIGIP_CLIENT_SSL_PROFILE_DISABLE = yes/no - Whether to create ClientSSL profile or just install the cert/key/chain into certificate store (defaults to: no)
# (this also means that everytime a new cert/key/chain is generated you will have to add it manually to a clientssl profile)
# DEPLOY_F5_BIGIP_CLIENT_SSL_PROFILE - Changes the name of the ClientSSL profile. The limit is 255 chars (imposed by bigip itself) (defaults to: SSL-ACME-${domain})
# DEPLOY_F5_BIGIP_CLIENT_SSL_PROFILE_SETTINGS - allows you to change the ClientSSL profile settings (defaults to: cipher-group f5-secure ciphers none options {no-tlsv1 no-tlsv1.1 dont-insert-empty-fragments})
# DEPLOY_F5_BIGIP_BACKUP = yes/no - Whether to keep 2 cert/key/chain combos (the installed one and a backup) at all times or delete the previously installed ones straight away (defaults to: yes)
