Hi <@UCJF480LR>. Simply by changing the tag on the subnet and then `pulumi up`.?

Perhaps it’s not that easy. Can you give us context:
1. Are you using the <https://www.pulumi.com/docs/reference/pkg/nodejs/pulumi/eks/|NodeJS-package >`@pulumi/eks`?
2. Or another language than TypeScript/JavaScript?

thanks,  it's nodeJS `eks` to setup a cluster, `awsx` to setup VPC.

tricky thing is that i need to create vpc before cluster, but subnet needs a cluster name in the tag, so it needs to be updated after cluster is created.

at least this is how i think it is.

```const vpc = new awsx.ec2.Vpc("xxx", {})
const cluster = new eks.Cluster("xxx", {
  vpcId: vpc.id,
  subnetIds: vpc.publicSubnetIds,
})

const subnets = vpc.publicSubnets```
is there a method to update tags? couldn't find it in the class description: <https://github.com/pulumi/pulumi-aws/blob/77e0ff920b7c5506e93aa1564cbe97b77621e377/sdk/nodejs/ec2/subnet.ts#L49>

If you’re fine to not have the <https://www.pulumi.com/docs/reference/pkg/nodejs/pulumi/eks/#ClusterOptions-name|automatic name suffix>, you could set the `eks.Cluster(name, {name})`.

&gt; subnet needs a cluster name in the tag
I don’t know such details. Sorry.

Might be good if you then ask in <#CRH5ENVDX|> channel.

thanks, much appreciated. setting a name without suffix would allow to set the tag on creation. that could work, thanks

original problem was setting up alb ingress. autodiscovery can get tricky there. finally i just set subnet ids annotation and it worked right away

You’re welcome. Just remembered there was a <https://pulumi-community.slack.com/archives/C84L4E3N1/p1582118168389100|similar issue with EKS and security-group ID>. Maybe that helps you, too.

Is it possible to create the name before the VPC, then pass it into both
- awsx.ec2.Vpc's constructor (args as `{ subnets: [ {type: "public", tags: { cluster: "name"}} ]`), and
- eks.Cluster (name).
