appengine-maven-repository

Private Maven repositories hosted on Google App-Engine, backed by Google Cloud Storage, supporting HTTP Basic authentication and minimalistic user access control deployed in less than 5 minutes.

Why ?

Private Maven repositories shouldn't cost you an arm and a leg, nor requires you to become a Linux Sys-Admin to setup, and should ideally be zero maintenance and costs nothing.

Thanks to Google App-Engine's free quotas, you'll benefits for free of:

  • 5GB of storage
  • 1GB of daily incoming bandwidth
  • 1GB of daily outgoing bandwidth
  • 20,000+ storage ops per day

Moreover, no credit card is required to benefits of the quotas above.

Installation

Prerequisites

Create a new Project

First of all, you'll need to go to your Google Cloud console to create a new App Engine application:

As soon as your project is created, a default Google Cloud storage bucket has been automatically created for you which provides the first 5GB of storage for free.

Setup the Google Cloud SDK

Follow the official documentation to install the latest Google Cloud SDK. As a shorthand, you'll find below the Ubuntu/Debian instructions:

$ export CLOUD_SDK_REPO="cloud-sdk-$(lsb_release -c -s)"
$ echo "deb http://packages.cloud.google.com/apt $CLOUD_SDK_REPO main" | sudo tee -a /etc/apt/sources.list.d/google-cloud-sdk.list
$ curl https://packages.cloud.google.com/apt/doc/apt-key.gpg | sudo apt-key add -
$ sudo apt-get update && sudo apt-get install google-cloud-sdk

Do not forget to install the app-engine-java component. If you installed the Google Cloud SDK using the instructions above:

$ sudo apt-get install google-cloud-sdk-app-engine-java

As a last step, configure the gcloud command line environment and select your newly created App Engine project when requested to do so:

$ gcloud init
$ gcloud auth application-default login

Configuration

Clone (or download) the source code:

$ git clone https://github.com/renaudcerrato/appengine-maven-repository.git

Update WEB-INF/users.txt to declare users, passwords and permissions:

# That file declares your users - using basic authentication.
# Minimalistic access control is provided through the following permissions: write, read, or list.
# Syntax is:
# <username>:<password>:<permission>
# (use '*' as username and password to declare anonymous users)
admin:l33t:write
john:j123:read
donald:coolpw:read
guest:guest:list

The list permission allows users to list the content of the repository but prohibits downloads. The read permission allows downloads (and implies list). The write permission allows uploads (and implies read).

Anonymous users are supported by using "*" for both username and password. For example, *:*:read will allow anonymous read access.

Deployment

Once you're ready to go live, just push the application to Google App-Engine:

$ cd appengine-maven-repository
$ ./gradlew appengineDeploy

And voilà! Your private Maven repository is hosted and running at the following address:

https://<your-project-id>.appspot.com

Usage

You'll find some usage examples in the examples folder. There's absolutely no extra steps required to fetch and/or deploy Maven artifacts to your repository: simply use your favorite Maven tools as you're used to do.

An example deploying artifacts using the maven plugin for Gradle:

apply plugin: 'java'
apply plugin: 'maven'

...

uploadArchives {
    repositories {
        mavenDeployer {
            repository(url: "https://<your-project-id>.appspot.com") {
                authentication(userName: "admin", password: "s3curepa55w0rd")
            }
            pom.version = "1.0.0"
            pom.artifactId = "test"
            pom.groupId = "com.example"
        }
    }
}

Using the above plugin, deploying artifacts to your repository is as simple as:

$ ./gradlew upload

In the other way, accessing password protected Maven repositories using Gradle only requires you to specify the credentials closure:

repositories {
    ...
    maven {
        credentials {
            username 'user'
            password 'YouCantGuess'
        }
        url "https://<your-project-id>.appspot.com"
    }
}

Ensure you do NOT commit credentials with your code. With Gradle, you can achieve this by amending the above examples using the approach specified here of moving your creds to ~/.gradle/gradle.properties and only referring to the variable names within your build.

Limitations

Google App-Engine HTTP requests are limited to 32MB - and thus, any artifacts above that limit can't be hosted.

File Management (Google Cloud File Storage)

The provided examples only provide a few gradle files that upload an installed local maven artifact. Sometimes there might be need to perform more file functions not available from gradle such as deletion. The documentation includes a button that launches a browser based file browser which presents a browser interface to perform file management.
