HCL-Vsphere-Infra

Hands-On Ready IaC for Vsphere, Terraform and Packer stack

Acknowledgements

Only ubuntu-server 20.04 lts version OS user-data and os specific configurations should be considered for this module. All sensible value containing extensions (.tfstate, .pkvars, .tfvars)should be treated as a secret.

Deployment

Install Terraform ~ v1.2.7
Install Packer ~ v1.8.3
Clone the repository To deploy this project you should set general aggregated variables for both tools in root folder. Also for packer additional local variable values should be set for each type of packer template (i.e consul.pkr.hcl - containing values for consul server)

Consolidated inputs:

File containing input variables for Terraform variables.tf should be created as a symlink to the variables.hcl file in root folder.
File containing input variables for Packer variables.pkr.hcl should be created as a symlink to the variables.hcl file in root folder.

File containing input variable values for Terraform terraform.tfvars should be created as a symlink to the values.hcl file in root folder.
File containing input variable values for Packer packer.auto.pkrvars.hcl should be created as a symlink to the values.hcl file in root folder.

Usage/Examples

Packer scripts should be launched only with bash executable -> packer-build

Data containin file examples are shown below.
