+# This script can be used to automate the setting of git commits in the values file to the head of each branch specified in the
+# package's git settings. To run simply run:
+
+# ./hack/update.sh
+
+# which will call updates on istio, clusterAuditor, gatekeeper, logging, monitoring and twistlock.  
+# As more addons get added we will have to update the wrapper script to know about them, or loop
+# over all addons.X section.
+
+# To update just one package, pass it as an argument into the script:
+
+# ./hack/update.sh monitoring
+
+
+
+# Assumes we have yq installed
+function update() {
+   # Get the git repo
+   REPO=`yq r chart/values.yaml "$1.git.repo"`
+   # Get the current branch specified in the values file
+   CURR_BRANCH=`yq r chart/values.yaml "$1.git.branch"`
+   # use the ls-remote git command to pull put the newest commit on that branch
+   NEW_HEAD=`git ls-remote ${REPO} | grep "refs/heads/${CURR_BRANCH}" | cut -f 1`
+
+#    echo "REPO: ${REPO}"
+#    echo "CURR_BRANCH: ${CURR_BRANCH}"
+#    echo "NEW_HEAD: ${NEW_HEAD}"
