Execute commands when SIGTERM received K8S - docker

Question

I am having difficulty with getting script to run when a pod is executed and running, I have a python script and install registration command running but when I test with deleting the pod which sends SIGTERM, I never recieve the output of the command or deos the command / function run.
Dockerfile and entrpoint are set correctly
CMD ["/app/entrypoint.sh"]
entrypoint both of script
## Remove
removal() {
echo "Removing agent..."
python3 /app/token_getter.py
GET_TOKEN=$(cat /app/token.txt)
cat <<< $GET_TOKEN | login --with-token
}
#Trap SIGTERM
trap 'removal' SIGTERM
## Add Agent
AGENT_NAME=$HOSTNAME-$RANDOM
echo $AGENT_NAME > /app/agent_name.txt
./config.sh --unattended --name $AGENT_NAME --labels $AGENT_NAME
./run.sh --once
The Add Agent commands run fine and registers and just runs in background, when I kill the pod , I cannot seem to get the removal command to run. I see below in logs each time.
