04/27/2020, 4:18 PMHello, I have some questions on the pulumi 2 migration I didn’t see covered in the migration guide.
Is the pulumi v2 cli compatible with running pulumi v1 projects? Can I upgrade the cli and deploy old projects as usual?
How would I rewrite the following code to avoid requireOutputSync? I’ve tried casting to
pulumi.Output<string>[]unknown Copy code
const vpcId = stackRef.requireOutput('vpcId');
const vpcPrivateSubnetIds = <string[]>stackRef.requireOutputSync('vpcPrivateSubnetIds');
const vpcPublicSubnetIds = <string[]>stackRef.requireOutputSync('vpcPublicSubnetIds');
const vpc = awsx.ec2.Vpc.fromExistingIds('vpc', {
privateSubnetIds: vpcPrivateSubnetIds,
publicSubnetIds: vpcPublicSubnetIds,
vpcId,
});f

04/27/2020, 10:17 PM@faint-table-42725 Regarding my 2nd question, this code typechecks on v2, but now pulumi is trying to delete my vpc, which is not what I want.
Copy code
const vpcId = stackRef.requireOutput('vpcId');
const vpcPrivateSubnetIds = (stackRef.requireOutput('vpcPrivateSubnetIds') as unknown) as pulumi.Output<string>[];
const vpcPublicSubnetIds = (stackRef.requireOutput('vpcPublicSubnetIds') as unknown) as pulumi.Output<string>[];
const vpc = awsx.ec2.Vpc.fromExistingIds('vpc', {
privateSubnetIds: vpcPrivateSubnetIds,
publicSubnetIds: vpcPublicSubnetIds,
vpcId,
});f

04/28/2020, 12:31 AMI don’t know if you can cast like that because I would expect the actual type to be
Output<string[]>a

04/28/2020, 4:03 AMI ended up casting to Output<string[]> like you said, and it does work if I then wrap the rest of my code in apply, like so:
Copy code
const vpcId = stackRef.requireOutput('vpcId');
let vpcPrivateSubnetIds = stackRef.requireOutput('vpcPrivateSubnetIds') as pulumi.Output<string[]>;
let vpcPublicSubnetIds = stackRef.requireOutput('vpcPublicSubnetIds') as pulumi.Output<string[]>;
pulumi.all([vpcPrivateSubnetIds, vpcPublicSubnetIds]).apply(([priv, pub]) => {
const vpc = awsx.ec2.Vpc.fromExistingIds('vpc', {
privateSubnetIds: priv,
publicSubnetIds: pub,
vpcId,
});
