I'm currently trying to find the best way to install the Jumpcloud package to a machine and then also pass a connect key via script. The connect key will not change more than a few times a year at which part I can update the script.
I'm trying to "dumb down" the below script which also installs the Jumpcloud agent using a specific user and then silently passes the connect key. I no longer need the specific user and just need the package installed and then the key passed silently under the logged in user. The current script also pulls the current version of the Jumpcloud agent to install.
I'm either trying to figure out way to modify this script to just download and install the Jumpcloud agent using the Amazon link in the script and then silently pass the connect key or if it's easier and less problematic attach a shorter script that just passes the connect key during the PKG install via a policy ie: the Jumpcloud.pkg is attached to a policy that also triggers a script to pass the Connect Key.
Due to other internal complications the script itself will not work for my use case.
If anyone has any ideas they would be very much appreciated.
#!/bin/bash
#
# Populate the below variables before running the command
#
# Enter your connect key within the '' of YOUR_CONNECT_KEY='' with your orgs key found on the new system aside in the admin console
YOUR_CONNECT_KEY='XXXXXX'
# Enter the SECURETOKEN_ADMIN_USERNAME within the '' of SECURETOKEN_ADMIN_USERNAME=''
SECURETOKEN_ADMIN_USERNAME=USERREMOVED’
# Enter the SECURETOKEN_ADMIN_PASSWORD within the '' of SECURETOKEN_ADMIN_PASSWORD='' with the credentials of the admin with a secure token
SECURETOKEN_ADMIN_PASSWORD='XXXXX'
# Flag for installing without checking SECURETOKEN_ADMIN_USERNAME or SECURETOKEN_ADMIN_PASSWORD
SILENT_INSTALL=1
# You can also specify one or more values with parameters
# -k YOUR_CONNECT_KEY -u SECURETOKEN_ADMIN_USERNAME -p SECURETOKEN_ADMIN_PASSWORD
while getopts k:u:p:sh option; do
case "${option}" in
k) YOUR_CONNECT_KEY=${OPTARG} ;;
u) SECURETOKEN_ADMIN_USERNAME=${OPTARG} ;;
