Testing Addons

This repository contains testing addons for the cert-manager project.

It is to save time when testing cert-manager working with external dependencies.

Mainly refer this proposal.

Current Available Workflows:

• Cert-manager and Vault
• Cert-manager and Gateway
• Cert-manager and Ingress

Precondition

Install Kubectl

Kubectl is used to perform actions that are not supported by native Terraform resources

Install Helm

Helm is the best way to find, share, and use software built for Kubernetes.

Install Terraform

Terraform is an IT infrastructure automation orchestration tool.

Install Terragrunt

Terragrunt is a thin wrapper that provides extra tools for keeping your configurations DRY, working with multiple Terraform modules, and managing remote state.

Configure Terraform Plugin Cache.

The configuration directory of each dependence can share the cache to improve the execution speed.

$ mkdir -p $HOME/.terraform.d/plugin-cache
$ export TF_PLUGIN_CACHE_DIR="$HOME/.terraform.d/plugin-cache" 

Usage Steps

Take Vault as an example.

1. Go to the installation directory of specific dependency.

cd cm-vault

2. Execute terragrunt run-all init

$ terragrunt run-all init
