Beginning right this moment, directors of bundle repositories can handle the configuration of a number of packages in a single single place with the brand new AWS CodeArtifact bundle group configuration functionality. A bundle group lets you outline how packages are up to date by inside builders or from upstream repositories. Now you can permit or block inside builders to publish packages or permit or block upstream updates for a gaggle of packages.
CodeArtifact is a completely managed bundle repository service that makes it simple for organizations to securely retailer and share software program packages used for software improvement. You should utilize CodeArtifact with standard construct instruments and bundle managers corresponding to NuGet, Maven, Gradle, npm, yarn, pip, twine, and the Swift Bundle Supervisor.
CodeArtifact helps on-demand importing of packages from public repositories corresponding to npmjs.com, maven.org, and pypi.org. This enables your group’s builders to fetch all their packages from one single supply of reality: your CodeArtifact repository.
Easy functions routinely embody dozens of packages. Massive enterprise functions might need a whole lot of dependencies. These packages assist builders pace up the event and testing course of by offering code that solves frequent programming challenges corresponding to community entry, cryptographic features, or information format manipulation. These packages is likely to be produced by different groups in your group or maintained by third events, corresponding to open supply initiatives.
To reduce the dangers of provide chain assaults, some organizations manually vet the packages which can be obtainable in inside repositories and the builders who’re licensed to replace these packages. There are 3 ways to replace a bundle in a repository. Chosen builders in your group would possibly push bundle updates. That is sometimes the case on your group’s inside packages. Packages may also be imported from upstream repositories. An upstream repository is likely to be one other CodeArtifact repository, corresponding to a company-wide supply of authorized packages or exterior public repositories providing standard open supply packages.
Here’s a diagram exhibiting totally different potentialities to show a bundle to your builders.
When managing a repository, it’s essential to outline how packages may be downloaded and up to date. Permitting bundle set up or updates from exterior upstream repositories exposes your group to typosquatting or dependency confusion assaults, for instance. Think about a nasty actor publishing a malicious model of a well known bundle underneath a barely totally different title. For instance, as a substitute of coffee-script, the malicious bundle is cofee-script, with just one “f.” When your repository is configured to permit retrieval from upstream exterior repositories, all it takes is a distracted developer working late at evening to sort npm set up cofee-script as a substitute of npm set up coffee-script to inject malicious code into your techniques.
CodeArtifact defines three permissions for the three doable methods of updating a bundle. Directors can permit or block set up and updates coming from inside publish instructions, from an inside upstream repository, or from an exterior upstream repository.
Till right this moment, repository directors needed to handle these vital safety settings bundle by bundle. With right this moment’s replace, repository directors can outline these three safety parameters for a gaggle of packages directly. The packages are recognized by their sort, their namespace, and their title. This new functionality operates on the area stage, not the repository stage. It permits directors to implement a rule for a bundle group throughout all repositories of their area. They don’t have to keep up bundle origin controls configuration in each repository.
Let’s see intimately the way it works
Think about that I handle an inside bundle repository with CodeArtifact and that I need to distribute solely the variations of the AWS SDK for Python, often known as boto3, which have been vetted by my group.
I navigate to the CodeArtifact web page within the AWS Administration Console, and I create a python-aws repository that can serve vetted packages to inside builders.
This creates a staging repository along with the repository I created. The exterior packages from pypi will first be staged within the pypi-store inside repository, the place I’ll confirm them earlier than serving them to the python-aws repository. Right here is the place my builders will hook up with obtain them.
By default, when a developer authenticates towards CodeArtifact and kinds pip set up boto3, CodeArtifact downloads the packages from the general public pypi repository, levels them on pypi-store, and copies them on python-aws.
Now, think about I need to block CodeArtifact from fetching bundle updates from the upstream exterior pypi repository. I need python-aws to solely serve packages that I authorized from my pypi-store inside repository.
With the brand new functionality that we launched right this moment, I can now apply this configuration for a gaggle of packages. I navigate to my area and choose the Bundle Teams tab. Then, I choose the Create Bundle Group button.
I enter the Bundle group definition. This expression defines what packages are included on this group. Packages are recognized utilizing a mixture of three elements: bundle format, an non-compulsory namespace, and title.
Listed here are just a few examples of patterns that you should use for every of the allowed mixtures:
- All bundle codecs: /*
- A particular bundle format: /npm/*
- Bundle format and namespace prefix: /maven/com.amazon~
- Bundle format and namespace: /npm/aws-amplify/*
- Bundle format, namespace, and title prefix: /npm/aws-amplify/ui~
- Bundle format, namespace, and title: /maven/org.apache.logging.log4j/log4j-core$
I invite you to learn the documentation to study all the chances.
In my instance, there isn’t a idea of namespace for Python packages, and I need the group to incorporate all packages with names beginning with boto3 coming from pypi. Due to this fact, I write /pypi//boto3~.
Then, I outline the safety parameters for my bundle group. On this instance, I don’t need my group’s builders to publish updates. I additionally don’t need CodeArtifact to fetch new variations from the exterior upstream repositories. I need to authorize solely bundle updates from my inside staging listing.
I uncheck all Inherit from mum or dad group bins. I choose Block for Publish and Exterior upstream. I depart Enable on Inside upstream. Then, I choose Create Bundle Group.
As soon as outlined, builders are unable to put in totally different bundle variations than those licensed within the python-aws repository. After I, as a developer, attempt to set up one other model of the boto3 bundle, I obtain an error message. That is anticipated as a result of the newer model of the boto3 bundle isn’t obtainable within the upstream staging repo, and there’s block rule that forestalls fetching packages or bundle updates from exterior upstream repositories.
Equally, let’s think about your administrator needs to guard your group from dependency substitution assaults. All of your inside Python bundle names begin along with your firm title (mycompany). The administrator needs to dam builders for by chance downloading from pypi.org packages that begin with mycompany.
Administrator creates a rule with the sample /pypi//mycompany~ with publish=permit, exterior upstream=block, and inside upstream=block. With this configuration, inside builders or your CI/CD pipeline can publish these packages, however CodeArtifact is not going to import any packages from pypi.org that begin with mycompany, corresponding to mycompany.foo or mycompany.bar. This prevents dependency substitution assaults for these packages.
Bundle teams can be found in all AWS Areas the place CodeArtifact is offered, at no further price. It lets you higher management how packages and bundle updates land in your inside repositories. It helps to forestall numerous provide chain assaults, corresponding to typosquatting or dependency confusion. It’s one further configuration you could add right this moment into your infrastructure-as-code (IaC) instruments to create and handle your CodeArtifact repositories.
