I tried to delete a cluster:
	"The Cluster cannot be deleted while Services are active."
I tried to delete the service called 'nginx':
	"The service cannot be stopped while the primary deployment is scaled above 0"

	Select service, click 'Update' - set 'Number of tasks' to 0
	This changed the number of 'Desired Tasks' to 0

Or I guess:
aws ecs update-service --service nginx --desired-count 0 --cluster ecscluster1 --profile devops

How to: Allow Node to bind to port 80 without sudo

TL;DR

Only do this if you understand the consequences: all node programs will be able to bind on ports < 1024

sudo setcap 'cap_net_bind_service=+ep' /usr/local/bin/node

Important: your node location may vary. Use which node to find it, or use it directly in the command:
