GitOps repo module

Module that prepares a GitOps repo for use with ArgoCD. If the provision flag is true then a new git repo will be provisioned. If not, the provided repo name is expected to already exist.

After cloning the git repo, an initial directory structure is set up along with bootstrap configuration to perform the initial setup of ArgoCD.

Supported git servers

The module supports creating a repository in one of six different git servers:

• GitHub
• GitHub Enterprise
• Gitlab
• Bitbucket
• Gitea
• Azure DevOps

The selection of the git server type is determined by the value provided for the host and the returned api headers.

Default git server config

This module allows for fall-back git server configuration if the git server configuration values are not provided as input. This default git server is typically Gitea and previously the gitea config values were explicitly provided as direct input to this module. With a recent change, these values have been removed and should be provided via the gitops provider configuration in the default_*** fields. See example/provider.tf for an example of this configuration.

Note: This is actually how the test case is configured. For all the test cases, the gitea config is provided for the default git server information. When the test case is non-gitea, the git server information is provided in the host, org, username, and token fields. For the gitea test case, those fields are left blank and the gitea config is used.

Software dependencies

The module depends on the following software components:

Command-line tools

• terraform >= v0.15
• git

Terraform providers

• cloud-native-toolkit/gitops
• cloud-native-toolkit/clis

Module dependencies

This module makes use of the output from other modules:

• Sealed Secret Cert - github.com/cloud-native-toolkit/terraform-util-sealed-secret-cert
