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

    + 2 to create
    - 1 to delete
    2 changes. 1 unchanged

Do you want to perform this update?
> no

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.

Choosing yes will proceed with the update.

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

  - bucketName : "my-bucket-68e33ec"
  + host       : ""

    + 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.
