An error occurred (MissingParameter) when calling the CreateRoute operation

Running part 11 (https://github.com/prabhatsharma/kubernetes-the-hard-way-aws/blob/master/docs/11-pod-network-routes.md) and running into this message. Probably missing something really dumb that I did myself.

Hi, Probably you have closed/change your terminal/console. You will need to set up again variables which point to your routing table:

VPC_ID=$(aws ec2 describe-vpcs --filters Name=tag:Name,Values=kubernetes-the-hard-way --output text --query 'Vpcs[0].VpcId') ROUTE_TABLE_ID=$(aws ec2 create-route-table --vpc-id ${VPC_ID} --output text --query 'RouteTable.RouteTableId')

I just hit the same issue as ROUTE_TABLE_ID does not appear to be defined. At least in the script in that section on setting up the routing.

I'll check your suggestion tstachlewski - thanks

You can query for the route table id again with this command: aws ec2 describe-route-tables --filters 'Name=tag:Name,Values=kubernetes' --query 'RouteTables[].Associations[].RouteTableId'
