Best Practice VPC Configuration for Red Hat Ansible

1 min read

Secure SSH access to IBM Cloud VPC Gen2 environments for application provisioning with Red Hat Ansible and IBM Cloud Schematics.

With IBM Cloud VPC, it is quick and simple to deploy new applications—a characteristic that becomes even more powerful when coupled with Terraform and Red Hat Ansible to automate the end-to-end deployment of both VPC infrastructure and applications. Applying Infrastructure as Code (IaC) principles, Terraform and Ansible enable open-source-based apps to be deployed repeatably and reliably into VPC Gen2 environments in minutes. 

Terraform modules for IBM Cloud Gen2 VPC

To get users started with Terraform, Red Hat Ansible, and VPC, IBM Cloud Schematics has released Terraform modules for IBM Cloud Gen2 VPC. These modules and an example Terraform template implement a best practice configuration for secure application provisioning with Ansible in VPC environments.

The example delivers an out-of-the-box implementation of SSH access via a bastion host. At the same time, it keeps strong control over network security configuration using VPC Security Groups and network Access Control Lists (ACLs). The configuration also gives Ansible users access to the wide choice of open source software available from public repositories. 

To get users started with Terraform, Red Hat Ansible, and VPC, IBM Cloud Schematics has released Terraform modules for IBM Cloud Gen2 VPC.

These Terraform 0.12 modules for application provisioning in IBM Cloud VPC environments support the following features:

  • Automation of network ACL and Security Group setup
  • Best practice application of ACLs and Security groups to secure SSH public network access
  • Bastion host deployment and config
  • Multi-tier application support  
  • Network config for multi-zone high availability
