Can someone help with this horrible bit of code that always wants to delete/replace network associations each time I up the stack its in: var i = 0; for (var subnetId of privateSubnetIds) { new aws.ec2clientvpn.NetworkAssociation(
assoc-${i}
, { clientVpnEndpointId: vpnEndpoint.id, subnetId: subnetId, }); i++; }
I tried sorting the privateSubnetIds.sort() but that didn't help.. still thinks there's always been a change to one of these network associations, like the ordering its getting the subnets is changing

Can you provide the
pulumi preview --diff
output?

Where is
privateSubnetIds
coming from?
I suspect you're right. The
privateSubnetIds
doesn't appear to be in consistent order. Sorting it should work.

The associations were created with .sort() but I still get the error. I removed them and tried again just in case, but still have the same problem.

Code is just privateSubnetIds.sort() .. privateSubnetIds is pulumi.Output<string>[] originating from awsx.ec2.Vpc.privateSubnetIds

If
privateSubnetId
is unique & stable (doesn't change), then you should be able to hash (sha1/md5) that value and use it to create an ID that won't change. If the ID doesn't change, pulumi won't try to delete/create - it will only update if the subnetId of vpnEndpoint.id value changes.

I would think privateSubnetId is unique and stable after the sort. I was trying to create a unique name with the assoc-${i} there. I'm not sure why a more complex string there would help things unless I need to use that value in some other way.

Does it make any difference if you use the subnetIds to name the association? ``assoc-${subnetId}``

i'll give that a shot. it's certainly makes for a cleaner look.
i do like that code better, but unfortunately it does not fix it: pulumipulumiStack: (same) [urn=urnpulumistage:managed infrapulumipulumiStack:managed-infra-stage] +-awsec2clientvpn/networkAssociationNetworkAssociation: (replace) [id=cvpn-assoc-0a4503e03505d5108] [urn=urnpulumistage:managed infraawsec2clientvpn/networkAssociationNetworkAssociation:assoc-subnet-08301af09876e1446] [provider=urnpulumistage:managed infrapulumiprovidersawsdefault 1 19 0:20df1138-1914-4916-aa26-b87c05e0ab2d] ~ subnetId: "subnet-037eec31203453d7b" => "subnet-08301af09876e1446" +-awsec2clientvpn/networkAssociationNetworkAssociation: (replace) [id=cvpn-assoc-023b05af829b07830] [urn=urnpulumistage:managed infraawsec2clientvpn/networkAssociationNetworkAssociation:assoc-subnet-0d8f31780fdb9602b] [provider=urnpulumistage:managed infrapulumiprovidersawsdefault 1 19 0:20df1138-1914-4916-aa26-b87c05e0ab2d] ~ subnetId: "subnet-037eec31203453d7b" => "subnet-0d8f31780fdb9602b" Resources: +-2 to replace 52 unchanged Permalink: https://app.pulumi.com/Synthesis-AI-Dev/managed-infra/stage/previews/7d5cd998-3ac9-43d1-8bd8-9f7b191bb86e
code now looks like this: for (var subnetId of privateSubnetIds) { subnetId.apply(subnetId => new aws.ec2clientvpn.NetworkAssociation(
assoc-${subnetId}
, { clientVpnEndpointId: vpnEndpoint.id, subnetId: subnetId, })); }
that's after first removing the ones that were there (assoc-[0-2]) and creating with the code above.. and then the following preview --diff. ugh!

Seems like a bug to me. Not sure how else to explain it 😞
