Create a Virtual Private Cloud (VPC)¶

In this section, you will create and configure a Virtual Private Cloud (VPC) and configure the related resources for your VPC like the subnet, security group and floating IP.

Environment Variables¶

Set the following environment variables to be used in the remainder of the tutorial. Set the USERNAME to a unique value shorter than 10 characters and set the IBMID to the email you used to create the IBM Cloud account. The other variables don't need to be changed but you can choose to rename them if you prefer.

USERNAME=<bnewell>
IBMID=<b.newell2@email.com>

Using the previous values, set the following environment variables,

RESOURCE_GROUP=$MY_RG
MY_REGION=us-south
MY_ZONE=$MY_REGION-1
MY_VPC_NAME=$USERNAME-vpc1
MY_VPC_SUBNET_NAME=$USERNAME-vpcsubnet1
MY_PUBLIC_GATEWAY=$USERNAME-public-gateway1
MY_NAMESPACE=my-guestbook

Set Targets¶

Target the region and the resource group to create our VPC environment.

ibmcloud target -r $MY_REGION -g $RESOURCE_GROUP

The VPC must be set up in the same multi-zone metro location where you want to create your cluster. Target generation 2 infrastructure.

$ ibmcloud is target --gen 2
Target Generation: 2

Create a VPC¶

This section uses the IBM Cloud CLI to create a cluster in your VPC on generation 2 compute.
