AWS RDS Versions

What is it

This repository contains tags with all versions of AWS RDS databases of type aurora-postgresql that are updated regularly using the official AWS RDS API. The purpose of this repo is to provide a datasource for Renovate to monitor and update the database engine versions in your Terraform files.

How it works

This repo uses a GitHub Action to fetch the latest RDS versions from the AWS API and create or update the corresponding tags. The tags are named as engine_version, such as 13.4. The tags are sorted by the docker versioning scheme, which follows the semantic versioning rules. The GitHub Action runs every Monday at 00:00 UTC and pushes any new or updated tags to this repo.

How to use

To use this repo, you need to have Renovate installed and configured. You need to add a custom regex manager in your renovate.json file, like this for example:

"regexManagers": [ 
   { 
     "description": "Update AWS RDS versions", 
     "fileMatch": ["^.*/[^/]+\.(tf|tfvars)$"], 
     "matchStringsStrategy": "combination", 
     "matchStrings": [
        "engine\\s*=\\s*\"(?.*)\"",
        "\\sengine_version\\s*=\\s*\"(?.*)\""
      ], 
      "datasourceTemplate": "github-tags",
      "depNameTemplate": "Revolgy-Business-Solutions/{{{depName}}}",
      "versioningTemplate": "docker" 
    } 
 ]

The regex manager will match the engine name and version from your Terraform files that match the file pattern:

engine         =  "aurora-postgresql"
engine_version =  "14.7"

The regex manager will use the github-tags datasource to fetch the latest tags from this repo as the available versions for the engine.
