15.3. Creating and automatically uploading images to the AWS Cloud AMI

Procedure

1. In the RHEL image builder dashboard, click the blueprint name that you previously created.
2. Select the tab Images.

3. Click Create Image to create your customized image.

   The Create Image window opens.

   1. From the Type drop-down menu list, select Amazon Machine Image Disk (.raw).
   2. Check the Upload to AWS checkbox to upload your image to the AWS Cloud and click Next.

   3. To authenticate your access to AWS, type your AWS access key ID and AWS secret access key in the corresponding fields. Click Next.

      注記

      You can view your AWS secret access key only when you create a new Access Key ID. If you do not know your Secret Key, generate a new Access Key ID.

   4. Type the name of the image in the Image name field, type the Amazon bucket name in the Amazon S3 bucket name field, and type the AWS region field for the bucket you are going to add your customized image to. Click Next.

   5. Review the information and click Finish.

      Optionally, click Back to modify any incorrect details.

      注記

      You must have the correct IAM settings for the bucket you are going to send your customized image to. This procedure uses the IAM Import and Export, so you have to set up a policy for your bucket before you are able to upload images to it. For more information, see Required Permissions for IAM Users.

4. A pop-up on the upper right informs you of the saving progress. It also informs that the image creation has been initiated, the progress of this image creation, and the subsequent upload to the AWS Cloud.

   After the process is complete, you can see the Image build complete status.

5. In a browser, access Service→EC2.

   1. On the AWS console dashboard menu, choose the correct region. The image must have the Available status to indicate that it is uploaded.
   2. On the AWS dashboard, select your image and click Launch.
6. A new window opens. Choose an instance type according to the resources you need to start your image. Click Review and Launch.
7. Review your instance start details. You can edit each section if you need to make any changes. Click Launch.

8. Before you start the instance, select a public key to access it.

   You can either use the key pair you already have or you can create a new key pair.

   Follow the next steps to create a new key pair in EC2 and attach it to the new instance.

   1. From the drop-down menu list, select Create a new key pair.
   2. Enter the name of the new key pair. It generates a new key pair.
   3. Click Download Key Pair to save the new key pair on your local system.

9. Then, you can click Launch Instance to start your instance.

   You can check the status of the instance, which displays as Initializing.

10. After the instance status is running, the Connect button becomes available.

11. Click Connect. A window is displayed with instructions on how to connect by using SSH.

    1. Select A standalone SSH client as the preferred connection method to open a terminal.

    2. In the location where you store your private key, ensure that your key is publicly viewable for SSH to work. To do so, run the command:

       $ chmod 400 <your_instance_name>.pem

    3. Connect to your instance by using its Public DNS:

       $ ssh -i <your-instance_name>.pem ec2-user@<your-instance-IP-address>

    4. Type yes to confirm that you want to continue connecting.

       As a result, you are connected to your instance over SSH.
