I made ec2
instance with this code.
const ec2Instance = new ec2.Instance(this, "Instance", {
vpc,
instanceType: ec2.InstanceType.of(
ec2.InstanceClass.T2,
ec2.InstanceSize.MICRO
),
machineImage: new ec2.AmazonLinuxImage({
generation: ec2.AmazonLinuxGeneration.AMAZON_LINUX_2,
cpuType: ec2.AmazonLinuxCpuType.X86_64,
}),
securityGroup: securityGroup,
keyName: "default_aws"
});
ec2
is correctly made but ,there is no application in int ( That's of course)
Normally, after starting the ec2
I log-in and do some commands such as
sudo yum update
sudo yum install wget
sudo yum install emacs
I want to exec these command as default when ec 2 is built.
For Docker image I can write the command in Dockerfile
Is there any equivalent things to do?
- I checked the ec2 aws UI and found some images and template, is it relevant?
2)Or Can I have something like start scripts in cdk
??
I guess It might be common requirement, though, I can't find good information yet.
My final goal is making mysql installed ec2 with cdk, but at first I need to understand the basic idea of ec2
start script
CodePudding user response:
You can put those commands in a file and read that file in the script like so:
const userDataScript = readFileSync('./lib/user-data.sh', 'utf8');
// add user data to the EC2 instance
ec2Instance.addUserData(userDataScript);
