CLI tools for working with AWS ECS Service Discovery. In the absense of any useful Console view of thw whole Service Discovery scene in an account, I've found it necessary to come up with all this.

shell.sh

# A "1-liner" for listing all services.
aws servicediscovery list-services --query 'Services[].{Id:Id,Name:Name}' --output text | sort -bk 2

# A "1-liner" for deleting cruft services, and any associated insttance registrations.
# The `$id` at the start is one from the first column of the above command to list services.
id=''; \
  instances=$( \
    aws servicediscovery list-instances --service-id $id --query 'Instances[*].Id' --output text \
    ); \
  for x in $instances; do
    echo "drop instance ${x} from ${id}"; \
    aws servicediscovery deregister-instance --service-id $id --instance-id $x; \
  done; \
  echo "delete service $id"; \
  sleep 2; \
  aws servicediscovery delete-service --id $id

# Create Service
# Needs two variables:
#  $SD_NAME   The name of the service to create
#  $SD_NS_ID  The ID of the Namespace to create the Service within
aws servicediscovery create-service \
  --name "${SD_NAME}" \
  --dns-config "NamespaceId=${SD_NS_ID},RoutingPolicy=MULTIVALUE,DnsRecords=[{Type=A,TTL=60}]"

#===================================

# ToDo:
#  * Adjust "list services" above to also output the Namespace for each
#  * Could probably employ `jq` to clean up output & mix together values from separate `aws` commands
