This happens when not reading the docs until the end. I was searching for an automated OS Management patch job to patch my Oracle Cloud Infrastructure compute instances. Thanks on Twitter to @svilmune, @dhoogfr and @patrickjoss, who show me the menu in the OCI GUI and yes, there is a scheduler. In the meantime, I wrote a small bash script based on the OCI-CLI and instance principals. Credits to Iterating OCI CLI list data in bash (apextips.blogspot.com).
Script
#!/bin/bash
set -e
# set compartment
comp=ocid1.compartment.oc1..aaaaaaaaoqti273775l2ye4xv4yqi35bcon3o4qb64yqfaxyj2jdagnvtsja
# start check
echo ""
echo "---------------------------------------------------------------------------------"
echo "OCI OS Management Update Check $(date)"
echo "---------------------------------------------------------------------------------"
#list OSMS registered instances
managedinstanceList=$(oci os-management managed-instance list -c $comp --auth instance_principal)
for i in $(echo "$managedinstanceList" | jq '.data | keys | .[]')
do
ocid=$(echo $managedinstanceList | jq -r ".data[$i].\"id\"")
displayname=$(echo $managedinstanceList | jq -r ".data[$i].\"display-name\"")
osfamily=$(echo $managedinstanceList | jq -r ".data[$i].\"os-family\"")
updatesavailable=$(echo $managedinstanceList | jq -r ".data[$i].\"updates-available\"")
rebootrequired=$(echo $managedinstanceList | jq -r ".data[$i].\"is-reboot-required\"")
# show details
echo "OCID: $ocid"
echo "Display Name: $displayname"
echo "OS Family: $osfamily"
echo "Updates available: $updatesavailable"
echo "Reboot required: $rebootrequired"
# verify if update is required or not
if [ $updatesavailable -gt 0 ] ; then
echo "id do an OS update on $displayname - please verify if an OS reboot is required"
oci os-management managed-instance install-all-updates --managed-instance-id $ocid --auth instance_principal

echo "no update for $displayname"
