Multi Registry Authenticator (MRA)

About

Overview

This Action enables bulk login to multiple container registries at once

Why did write this action?

When using the official login action provided by Docker, there is no possibility to login into multiple registries at once.
Therefore, I wanted to enable this feature and eliminate the need to run the login action N times within a workflow.

How does this action Work?

The action works very simple. It loops over a semicolon separated string of registries and logs into them.

What are the limitations of this Action?

This action in its 1st version does not support logout from registries as post job stage. This feature will be supported soon in the 2nd version.

Usage

Using this Action is just as simple as using the official Docker/login-action.

Caution

Please store registry access credentials in a secure place such as GitHub Secrets

Input

registries:
- Required: Yes
- Description: A Multi-line string containing all registries to log into. Each in the format: REGISTRY_HOST;USERNAME;PASSWORD

Example
