I created a VPC like this:

new awsx.ec2.Vpc("vpc-dev-1", {
        cidrBlock: "10.0.0.0/16",
        instanceTenancy: "default",
        numberOfAvailabilityZones: 3,
        numberOfNatGateways: 2,
});

I now realize I need some tags on each public and private subnet. Is there a way to easily go back and add those tags to each subnet without destroying and re-creating the entire stack?

Maybe https://www.pulumi.com/registry/packages/aws/api-docs/ec2/tag/ ?

@mammoth-airline-91759 absolutely! tags are not an immutable API call, so just update your code, something like this:

const vpc = new awsx.ec2.Vpc(`${name}-vpc`, {
    cidrBlock: "172.16.0.0/24",
    subnets: [
        {
            type: "private",
            tags: {
                "<http://kubernetes.io/role/internal-elb|kubernetes.io/role/internal-elb>": "1",
            }
        },
        {
            type: "public",
            tags: {
                "<http://kubernetes.io/role/elb|kubernetes.io/role/elb>": "1",
            }
        }],
    tags: {
        Name: `${name}-vpc`,
        Owner: "lbriggs",
        owner: "lbriggs",
    }
});

I tried adding the

subnets

array, but the

pulumi up

preview showed replacements for all of the vpc components.

ah that's probably because the subnets themselves weren't defined, I'd suggest trying @wonderful-twilight-70958's suggestion

adding the tags using

ec2.Tag

worked. thanks folks!
