How do I set up a AWS Cloud9 instance using AWS-CDK? - amazon-web-services

Question

I love the idea behind the AWS CDK, but I'm struggling to create a Cloud9 Environment using it.
Every time the below code runs, an "Error while creating Cloud9" error message pops up in the AWS console, followed by "CREATE_FAILED" in the local terminal. First instincts suggest that the way to implement cloud9 is to establish a connection between ec2 and cloud9 – but I don't have any idea how to do that – has anybody successfully used the CDK to create a Cloud9 environment? Any advice would be greatly appreciated.
AWS Console error message
VSCode terminal error message
scroll down a little further in ther terminal and this message is at the end:
Stack Deployments Failed: Error: The stack named MjwFirstCdkStack failed creation,
it may need to be manually deleted from the AWS console: ROLLBACK_COMPLETE: Cannot
create the AWS Cloud9 environment. There was a problem connecting to the environment.
The code used
import * as cdk from "aws-cdk-lib";
import * as ec2 from "aws-cdk-lib/aws-ec2";
import * as cloud9 from "aws-cdk-lib/aws-cloud9";
import { Construct } from "constructs";
export class MjwFirstCdkStack extends cdk.Stack {
constructor(scope: Construct, id: string, props?: cdk.StackProps) {
super(scope, id, props);
// create a vpc
const vpc = new ec2.Vpc(this, "my-vpc-id", {
natGateways: 1,
maxAzs: 2,
ipAddresses: ec2.IpAddresses.cidr("10.0.0.0/16"),
subnetConfiguration: [
{
name: "private-subnet-1",
subnetType: ec2.SubnetType.PRIVATE_WITH_EGRESS,
cidrMask: 24,
},
{
name: "public-subnet-1",
subnetType: ec2.SubnetType.PUBLIC,
cidrMask: 24,
},
],
});
// create a cloud9 env
const myCloud9Environment = new cloud9.CfnEnvironmentEC2(
this,
"MyCloud9Environment",
{
name: "MyCloud9EnvironmentName",
instanceType: "t2.micro",
automaticStopTimeMinutes: 60,
subnetId: vpc.privateSubnets[0].subnetId,
}
);
}
}

Answer 1

have you tried deploy to the public subnet, refer to the vpc requirements for Cloud9 here
note that you need to delete the previously failed deployment before you run "cdk deploy" again. this can be done from the CloudFormation console
