Step 5: Launch an Instance
Use AWS OpsWorks Stacks to start up an Ubuntu Server Amazon EC2 instance. This instance uses the settings that you defined in the layer you created earlier in this walkthrough. (For more information, see Instances.)
To launch the instance
In the service navigation pane, choose Instances. The Instances page is displayed.
For MyLinuxDemoLayer, choose Add an instance.
On the New tab, leave the defaults for the following:
Leave the defaults for the following:
Scaling type (24/7)
SSH key (Do not use a default SSH key)
Operating system (Ubuntu 14.04 LTS)
OpsWorks Agent version (Inherit from stack)
Tenancy (Default - Rely on VPC settings)
Root device type (EBS backed)
Volume type (General Purpose (SSD))
Volume size (8)
Your results must match the following screenshot:
Choose Add Instance. AWS OpsWorks Stacks adds the instance to the layer and displays the Instances page.
For MyLinuxDemoLayer, for demo1, for Actions, choose start:
Over the course of several minutes, the following occurs:
The setting up circle changes from 0 to 1.
Status turns from stopped to requested, to pending, to booting, to running_setup, and then finally to online. Note that this process can take several minutes.
After Status changes to online, the setting up circle indicator changes from 1 to 0, and the online circle changes from 0 to 1 and changes to bright green. Do not proceed until the online circle changes to bright green, and shows 1 instance online.
Your results must match the following screenshot before you continue (if you receive a failure message, you may want to consult the Debugging and Troubleshooting Guide):
You now have an instance that is ready for the app to be deployed to it.
If you want to log in to the instance to explore it further, you must first provide
AWS OpsWorks Stacks with information about your public SSH key (which you can create with tools such as
ssh-keygen or PuTTYgen), and then you must set permissions on the
MyLinuxDemoStack stack to enable your IAM user to log in to the
instance. For instructions, see Registering an IAM User's Public SSH Key and Logging In with SSH. If you plan to use SSH to connect to instances
through PuTTY, see Connecting to Your
Linux Instance from Windows Using PuTTY in the AWS documentation.
In the next step, you will deploy the app to the instance.
