Beginning immediately, 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 inner builders or from upstream repositories. Now you can permit or block inner builders to publish packages or permit or block upstream updates for a gaggle of packages.
CodeArtifact is a totally managed bundle repository service that makes it simple for organizations to securely retailer and share software program packages used for software improvement. You need to use CodeArtifact with well-liked 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 purposes routinely embrace dozens of packages. Giant enterprise purposes may need a whole lot of dependencies. These packages assist builders velocity up the event and testing course of by offering code that solves widespread programming challenges corresponding to community entry, cryptographic features, or information format manipulation. These packages could be produced by different groups in your group or maintained by third events, corresponding to open supply tasks.
To reduce the dangers of provide chain assaults, some organizations manually vet the packages which are out there in inner 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 in your group’s inner packages. Packages may also be imported from upstream repositories. An upstream repository could be one other CodeArtifact repository, corresponding to a company-wide supply of accepted packages or exterior public repositories providing well-liked open supply packages.
Here’s a diagram exhibiting totally different potentialities to reveal a bundle to your builders.
When managing a repository, it’s essential to outline how packages might 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 identify. 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 night time to kind npm set up cofee-script as a substitute of npm set up coffee-script to inject malicious code into your programs.
CodeArtifact defines three permissions for the three potential methods of updating a bundle. Directors can permit or block set up and updates coming from inner publish instructions, from an inner upstream repository, or from an exterior upstream repository.
Till immediately, repository directors needed to handle these essential safety settings bundle by bundle. With immediately’s replace, repository directors can outline these three safety parameters for a gaggle of packages without delay. The packages are recognized by their kind, their namespace, and their identify. This new functionality operates on the area degree, not the repository degree. It permits directors to implement a rule for a bundle group throughout all repositories of their area. They don’t have to take care of bundle origin controls configuration in each repository.
Let’s see intimately the way it works
Think about that I handle an inner bundle repository with CodeArtifact and that I wish 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 may serve vetted packages to inner 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 inner 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 wish to block CodeArtifact from fetching bundle updates from the upstream exterior pypi repository. I need python-aws to solely serve packages that I accepted from my pypi-store inner repository.
With the brand new functionality that we launched immediately, 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-obligatory namespace, and identify.
Listed below are a number of examples of patterns that you should use for every of the allowed combos:
- All bundle codecs: /*
- A selected bundle format: /npm/*
- Bundle format and namespace prefix: /maven/com.amazon~
- Bundle format and namespace: /npm/aws-amplify/*
- Bundle format, namespace, and identify prefix: /npm/aws-amplify/ui~
- Bundle format, namespace, and identify: /maven/org.apache.logging.log4j/log4j-core$
I invite you to learn the documentation to be taught all the probabilities.
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. Subsequently, 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 wish to authorize solely bundle updates from my inner staging listing.
I uncheck all Inherit from mum or dad group containers. I choose Block for Publish and Exterior upstream. I depart Enable on Inner 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 out there within the upstream staging repo, and there may be block rule that stops 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 inner Python bundle names begin together with your firm identify (mycompany). The administrator needs to dam builders for unintentionally 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 inner upstream=block. With this configuration, inner 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 obtainable, at no extra price. It lets you higher management how packages and bundle updates land in your inner repositories. It helps to stop numerous provide chain assaults, corresponding to typosquatting or dependency confusion. It’s one extra configuration that you may add immediately into your infrastructure-as-code (IaC) instruments to create and handle your CodeArtifact repositories.
