Overview

go-strategize is a simple CLI program that provisions your infrastructure using terraform and configures it using ansible. To connect the two, it assumes that you're writing the ansible inventory to a file somewhere with terraform.

To learn how to do that trick read local file example and hosts.tmpl.

go-strategize does the following in order:

• Clone your terraform and ansible playbooks
• [Optional] Copies your .tfvars file(terraform) over to the cloned terraform repo folder
• Makes sure some playbooks are available in the provided folder path for playbooks
• Executes terraform init and terraform apply
• Reads the (hopefully) generated ansible hosts file from the provided path
• Copies ssh public keys for passwordless auth using ssh-copy-id
• Executes ansible-galaxy collection install
• Executes all the playbooks present in a folder

It's specially useful for people who usually have very long running ansible playbooks and need them to be running in a closed network. Imagine you need to provision some VMs and then install vanila k8s or whatever application on them. In a closed network you probably don't care about SSH key verification. Assuming the these two points are valid, you can utilize go-strategize with flag '-strict=false' to skip hostname verification and go grab a cup of coffee while your infrastructure is being provisioned and configured!
