Deploy the Changes
Now let’s deploy our changes.
$ pulumi up
Pulumi computes the minimally disruptive change to achieve the desired state described by the program.
Previewing update (dev): Type Name Plan pulumi:pulumi:Stack quickstart-dev + ├─ aws:ec2:SecurityGroup web-secgrp create + ├─ aws:ec2:Instance web-server-www create - └─ aws:s3:Bucket my-bucket delete Resources: + 2 to create - 1 to delete 2 changes. 1 unchanged Do you want to perform this update? yes > no details
Pulumi will delete the bucket since we’re no longer defining it in our program, and it will create the EC2 security group and EC2 instance since those are now defined in the program.
yes will proceed with the update.
Do you want to perform this update? yes Updating (dev): Type Name Status pulumi:pulumi:Stack quickstart-dev + ├─ aws:ec2:SecurityGroup web-secgrp created + ├─ aws:ec2:Instance web-server-www created - └─ aws:s3:Bucket my-bucket deleted Outputs: - bucketName : "my-bucket-68e33ec" + host : "ec2-3-86-229-103.compute-1.amazonaws.com" Resources: + 2 created - 1 deleted 2 changes. 1 unchanged Duration: 44s
We can use
pulumi stack output to get the value of stack outputs from the CLI. So we can
curl the EC2 instance to see the HTTP server running there.
$ curl $(pulumi stack output host) Hello, World!
Next, we’ll destroy the stack.
