Hi! I'm trying to create a bastion host to connect my private (subnet) RDS. I created a VPC with

awsx

and it throws an error at assigning public subnet ID from newly created VPC to a new EC2 instance. Please help me.

const vpc = new awsx.ec2.Vpc("my-vpc");

// Create bastion host
const bastionHost = new awsc.ec2.Instance("bastion-host", {
  ami: ami.id,
  instanceType: awsc.ec2.InstanceTypes.T2_Micro,
  associatePublicIpAddress: true,
  // Reference the public subnet from the custom vpc above
  subnetId: vpc.publicSubnetIds.apply(x => x![0]), // ! Property apply does not exist on type ...
  vpcSecurityGroupIds: [ec2SecurityGroup.id],
  keyName: sshKey.keyName,
});

The publicSubnetIds array is automatically lifted. Don't use

apply()

.

subnetId: vpc.publicSubnetIds[0]

works fine.

I tried but it says

1. Element implicitly has an 'any' type because expression of type '0' can't be used to index type 'Promise<Output<string>[]>'.

Property '0' does not exist on type 'Promise<Output<string>[]>'.

Ah, that's awsx for you. Promises instead of outputs. Is there an equivalent method / member that gives outputs?

It works! Thanks, brother.
