3. if I want to publish a custom resource somewhere semi-officially, where would I do this? 4. doc error: https://www.pulumi.com/docs/iac/concepts/inputs-outputs/apply/ python code

server = aws.ec2.Instance(
    "web-server",
    ami="ami-0319ef1a70c93d5c8",
    instance_type="t2.micro",
)

url = instance.public_dns.apply(
    lambda dns_name: "https://" + dns_name
)

instead of

instance

it should be

server.
