Kubernetes has become the de facto platform for orchestrating containers. Open standards complement Kubernetes by defining best practices for its implementation. These standards are developed by the open-source Kubernetes community (not a single vendor), ensuring vendor neutrality, easier integration with other tools, and overall system efficiency.

, a Linux Foundation project, was created to establish open, industry-wide standards for container formats and runtimes. It focuses on two core specifications:

: A reference container runtime engine used by most container platforms, including Docker. It serves as the foundation for many modern runtime environments.

: Defines how containers are built, distributed, and executed. While Docker remains widely used, OCI represents the community's commitment to standardized, open container technologies.

This shift has driven demand for registries that support Helm chart storage in OCI format. 

Cloudsmith is proud to be one such registry

, fully supporting Helm charts with OCI compliance.

Cloudsmith support moves from EA to GA for OCI

 released today (5th June 2025), we’re announcing full support for Helm OCI. Previously, Cloudsmith offered a Docker registry (

) that was fully compliant with the OCI v1.1 standard. While users could push any OCI artifact to this registry, non-Docker artifacts were still displayed as Docker packages.

This functionality had been marked as Early Access (EA) in our documentation, as the user experience was fully optimized only for Docker. Although users could technically push and pull any OCI artifact, display limitations persisted for non-Docker types.

With today’s update, we’ve significantly improved our support by fully enabling Helm OCI. We've reworked the implementation and introduced a dedicated endpoint (

) which allows users to push and pull Helm charts as OCI artifacts, now correctly identified and displayed as Helm packages.

In addition, we're introducing a compatibility bridge that enables legacy Helm charts and OCI-based Helm charts to coexist. We are now in a unique position to support legacy Helm chart repositories and OCI, allowing our users to push via legacy means and pull via OCI - offering greater flexibility and smoother transitions.

Open Container Initiative (OCI) Support in Cloudsmith

Apache Maven is a popular and widely-used open-source build automation and project management tool primarily designed for Java projects.

We're excited to announce a major enhancement to our Maven repository support at Cloudsmith. As a Java developer, you can now upload and distribute 

 using Maven repositories, unlocking more flexible and powerful workflows for your projects.

Arbitrary files are files that are ignored by Maven unless explicitly included in the Project Object Model (

 configuration. This update means that Cloudsmith can now support unique package names that don't support Maven convention or use arbitrary classifiers or extensions, so really they should be able to upload any file regardless of the extension.

Previously, Cloudsmith Maven repositories only supported standard artifacts that followed the traditional 

). That meant non-standard files (such as custom dependencies, configuration files, or other useful assets) couldn’t be cached from upstream sources or uploaded directly.

you can now cache and distribute arbitrary files

, whether they’re pulled from upstream sources or uploaded directly using your preferred tooling.

Not every project follows the “standard” Maven structure (and that’s okay!). Whether you're dealing with:

Binary assets like .zip, .tar.gz, .exe, or .dmg

Configuration files, templates, or scripts

You can now fully embrace these flexible workflows without needing to hack around repository limitations. Cloudsmith's improved Maven support now includes:

: Cache and serve arbitrary files that don’t follow Maven’s strict packaging rules (even from external sources).

 Upload arbitrary files manually or automatically as part of your CI/CD pipeline.

Securely Store and Distribute OCI Artifacts

As software complexity advances, understanding what’s happening across every part of your software supply chain becomes crucial. You need to see where artifacts are used, how secure they are, and whether they meet compliance standards.

The ability to capture this is known as observability. Observability goes beyond data collection to provide essential insights that help teams understand, troubleshoot, and enhance complex systems. It enables engineers to ask critical questions, anticipate issues, and respond proactively—fostering resilience and reliability.

Overcoming the Challenges of Limited Observability

Without good observability, teams are often left in the dark, relying on incomplete data and reactive troubleshooting when issues arise. This can lead to longer downtime, unexpected costs, and missed security risks, as there’s no clear visibility into where problems occur or why. The lack of insights also makes it harder to anticipate trends, manage resources efficiently, and ensure compliance, ultimately compromising system reliability and customer trust.

Knowing this, we wanted to take a step forward and create a solution that provided a quick turnaround on insights that drive immediate corrective action. As a result, Cloudsmith has launched an advanced observability suite, offering enterprises unparalleled insights into their software supply chain. With a fully redesigned user experience, customers can now make data-driven decisions more effectively, managing artifacts with greater precision and control.

Enhanced Observability for Usage Management

Cloudsmith’s advanced observability features give engineering managers and DevOps teams the insights needed to monitor and manage artifact quality and usage across their systems. These tools are built to handle complex, large-scale environments, helping teams track trends, accurately attribute costs, and proactively address risks—essential for maintaining control over a dynamic software supply chain.

"Cloudsmith's analytics and alerts are instrumental in helping us manage our usage more effectively and plan for increases in demand for software artifacts,...We can catch unexpected spikes in artifact consumption, improving our security posture and avoid usage surprises at the end of the month" Dave Bresci, Senior Manager, SRE, PagerDuty.

Cloudsmith’s new observability suite offers several key features geared to upgrading observability:

: Granular dashboards and reports provide a clear view of consumption patterns over time, enabling informed resource management.

Introducing Cloudsmith’s Advanced Observability Suite for Enterprise Artifact Management

It’s a fairly common perception that a package repository is basically a file share or file storage, and perhaps for some of the most simple implementations, this is a reasonable analogy.

However, when thinking of Cloudsmith, this analogy misses a lot of important details that make Cloudsmith package repositories rather unique.

If you have used Cloudsmith, you may have noticed that when you publish/upload a package to Cloudsmith or fetch a package from a public package repository (Like Maven Central or PyPi) into Cloudsmith, the first thing that happens is that the package enters a “Synchronizing” state. What exactly is synchronizing?Put simply, synchronization is where Cloudsmith processes the uploaded/ingested package. But that still belies a lot of the detail. What possible processing could a package need? Well, quite a lot actually!

Some of the steps that synchronization/package processing involves are:

 - Setting up the initial state, tools and environment for synchronization.

 - Getting the package files from the upload storage location.

 - Extracting the package files and package assembly (layers and configs for Docker images, for example)

 - Once we have the complete package file set, we scan the files for trojans, malicious content etc.

 - Verify and generate package checksums and signatures, as well as parse and verify package metadata and licenses.

 - Local and Distributed Storage synchronization.

These processes are automatic, require no user interaction and run asynchronously on Cloudsmith's global infrastructure. They are a large part of what empowers Cloudsmith users to implement effective package controls. As they say, knowledge is power - and it’s by the process of synchronization that we gain the knowledge of packages.

Once a package has been synchronized, we can then use the metadata generated to apply things like Vulnerability, Licence and Package Deny policies, create a scoped access token, add tags to the package, or fire a webhook for specific packages/versions. The data generated from synchronization drives a lot of the subsequent actions and workflows that you can perform.

Also, you may encounter occasions where a package fails synchronization:

This is typically a good thing (contrary to initial impressions!) because it can alert you to a problem with the package itself such as invalid/missing/incorrect metadata (the package not meeting the specification for the package type, for example), the presence of Malware in the package, or that you are attempting to upload/publish a package that already exists in the repository (as above). Package synchronization is an essential step in verifying the “correctness” of a package and It’s always better to catch things earlier in your processes than later, as the cost of remediation rises dramatically the later issues are identified.

Cloudsmith Package Repositories do far more than just store your packages, and they have a lot more functionality than just storing your packages in an AWS S3 bucket or Azure Blob Storage, or spinning up a simplistic instance of a package repository. Packages in Cloudsmith repository are so much more than just “bits on disk”, and treating them as such is really doing them a disservice!

What happens when you upload a Package?

Package promotion workflows are a great way to isolate and protect production repositories, allowing progressive levels of security and permissiveness for development, staging, and production environments.

Once a binary is uploaded to Cloudsmith, it can move from development -> staging -> production, maintaining the integrity of the asset and its provenance trail. This migration takes place entirely within Cloudsmith; there’s no package delivery cost.

The differences between Dev, Staging and Production environments.

Cloudsmith's package promotion instructions- package copy/move actions

Complementary features that play nicely with package promotion, including webhooks, quarantining, policy management and upstreaming. These can be used together to create workflows and drive actions.

A Potential workflow for package promotion

Policy management that lets you set up policies that serve as prerequisites to package promotion.

Differences between Dev, Staging, and production environments

Typical software development organizations maintain three types of environments: development, stage, and production.

environment is used for developers early in the software process to see how new features will work, to try out improvements and pull in new dependencies or update existing dependencies.

 environment is used for testing integration and is a production-

environment that allows user creation without impacting production data. Only whitelisted IPs typically have access to Staging.

 environment is what end users are using on a live system.

Cloudsmith's package promotion workflows are powered by features to copy and move packages between repositories, usually for promoting immutable versions of packages between separate build, test, staging and production pipelines. The package that was verified in build is the same package in production when it gets promoted to there. Cloudsmith facilitates the automation of copying and moving packages using our command line interface (CLI).

 for vulnerabilities and license issues. This ensures that only secure and compliant artifacts are promoted through the pipeline, with policies applied to block or quarantine packages that fail these checks.

Let's see an example of moving a package in action:

 package was moved (or "promoted") from the source repository to the destination repository. Copying packages works the same, except it duplicates the package rather than moving it from the source to the destination.

In addition to moving and copying packages, you can also resync packages via the CLI, whereby the CLI will retry packages that have failed (for whatever reason) up to a configurable amount of attempts.

To see the full list of help for actions, run the following commands:

Package promotion on its own is great, and you can couple it with other features to create workflows and drive actions. Let's talk about tagging, webhooks, multiformat repos, vulnerability scanning, and setting up upstream.

 feature allows you to label your packages with tags like "dev", "staging", or "prod" as they move through your pipeline. These tags help in tracking packages across different environments, and enable targeted searches, filtering, and control over what artifacts are accessible. By using 

, you can automate package promotions based on tag transitions, such as promoting a "staging" package to "prod" once it passes certain tests). This enhances visibility and governance within your pipeline and simplifies the overall package management process.

Webhooks let apps send automated messages or information to other apps. 

 are great for integrating Cloudsmith with other systems in your build pipeline, by sending data or notifications to other tools in your stack and helping to enable automation across your workflows.

Cloudsmith has webhooks for vulnerability scanning. Anytime a scan is completed, Cloudsmith can dispatch a corresponding vulnerability webhook to trigger some action, like creating a Jira ticket.

Cloudsmith's vulnerability scanning is particularly effective when combined with upstreams. Upstream proxying and caching allow you to upload and use the packages you author in-house directly, while Cloudsmith fetches and caches your dependencies from public repositories like Maven Central or NuGet.org.

This enables you to use Cloudsmith as a first-class cache and a central source of truth for packages, to protect you from issues related to use of external services, such as downtime, rate limiting, or non-availability of a previously available package.

Packages fetched from a caching-enabled upstream will be automatically scanned for vulnerabilities for Ultra customers.

Multi-format repositories allow you to store artifacts of different formats in the same place. Organize your packages by environment, project, package type, or whatever way you see fit.

Package vulnerability scanning is a key step in securing your software delivery pipeline and reducing the risk of releasing insecure software into production.

Cloudsmith automatically scans every supported package format pushed to a Cloudsmith repository or fetched from a caching-enabled upstream.

Cloudsmith's vulnerability scanning feature is available for the following package formats:

Cloudsmith's Security Scanning page shows a breakdown of the number of packages scanned/not scanned, the age of scans, the pass/fail count overall and the maximum severity of those found.

Setup your Dev repository with upstreams and your Staging repos with no upstream

Push your package to Dev repository and tag the package with ‘dev’.

Automatically tag the package with ‘staging’ and move the package to the Staging repository when the results return with no vulnerabilities.NOTE: you may want to run more manual tests against this package before promoting it.

 for the examples below. The CLI interfaces with Cloudsmith's API and allows users, machines and other services to access and integrate smoothly with Cloudsmith without requiring explicit plugins or tools.

Setup your Dev repository with upstreams and your Staging repository with no upstreams

Create 2 repositories Dev and Staging by following the instructions 

.

Set up an upstream for the Dev repo by following the instructions 

A vulnerability scan is automatically triggered for supported packages every time they are pushed into a Cloudsmith repository. If you set up an upstream, your 3rd party dependencies are also scanned for vulnerabilities.

Cloudsmith supports over 30 different types of packages. 

Upload via the package-specific native CLI / tools e.g. using Maven's 

Upload via the API using tools/integrations (such as the official Cloudsmith CLI).

To upload a package via the Cloudsmith CLI, use the cloudsmith push command:

Setting up webhooks so Cloudsmith can send automated messages to alert another system when a package had been scanned is great for setting up vulnerability workflows.

 in your repository and then create a new webhook. Then:

 with the tool you want to receive your webhook like 

You can test out the Webhook by selecting to 

The webhook is triggered when the scan is finished and will have a payload in the HTTP req with information about the package and any vulnerabilities, including:

This information can drive actions such as tagging and promoting a package based on the maximum severity reported.

, use the command cloudsmith tag as follows:

cloudsmith tag add OWNER/REPOSITORY/PACKAGE TAG1, TAG2

 promote a package use the Cloudsmith CLI command cloudsmith cp or mv as follows:

For example, using the data from the snippet above where

cloudsmith cp demo/examples-repo/IB6FYhIvaoAy

Enhance your Workflows with Policy Management

To further secure and streamline your package promotion workflows, Cloudsmith’s 

 features can be used to automate and enforce critical security measures. With 

, you can automatically block or quarantine packages that violate license rules, while 

 scan for potential risks, quarantining packages based on severity. 

 enforce API-key rotation to ensure secure access.

These policies make your workflows more secure, compliant, and automated—minimizing manual intervention and reducing risk across your software supply chain. To explore these features in more detail, check out our blog on 

Looking ahead, Cloudsmith’s Enterprise Policy Manager will further enhance promotion workflows with advanced controls.

 It will allow policies to be applied at any decision point, ensuring real-time enforcement of security and compliance rules like “should we allow this action?”

How to Manage Your Package Promotion Workflows with Cloudsmith

Getting Started with Unity and Cloudsmith

A short demo of how to get started with Unity packages and Cloudsmith, including pushing a package to a private Cloudsmith repository and then adding a package to a Unity project.

It’s official: regulations by the US and UK governments are coming down the track to secure the software supply chain.


Earlier this month, President Biden signed an 

 (EO) to increase cybersecurity defences across the U.S, with an emphasis on enhancing the security of the software supply chain. Now, the 

 is following suit, having announced their own call for advice on defending against software supply-chain attacks. The supply chain attacks at SolarWinds and 

 have shaken governments. The EO targets the software industry when it says, “Too much of our software, including critical software, is shipped with significant vulnerabilities that our adversaries exploit.” The US wants to know what is in the software they rely on and how securely it is built.

How could this affect your DevOps and Software Engineering teams?


Within 60 days of the EO, the US government will publish the following:

Minimum elements for a Software Bill of Materials (SBOM).

Guidelines recommending minimum standards for vendors’ testing of their software source code, including identifying recommended types of manual or automated testing (such as code review tools, static and dynamic analysis, software composition tools, and penetration testing).


The SBOM is a critical element of the EO, essentially a record of all of the components and dependencies used in building software. Most software contains libraries and packages sourced from the open-source community or commercial software. The end-user can use the SBOM to perform vulnerability or license analysis, both of which can evaluate risk in a product.

The EO specifically calls out actions to prove the security and provenance of open-source software (OSS). There is a fear that the OSS supply chain is a potential avenue of attack for hackers. Most modern software relies on many OSS packages, which will only increase moving forward as software becomes more and more complex. The EO indicates that OSS packages used in software will need to be checked for:

The EO may force Software developers and DevOps Engineers to change their practices and update their CI/CD pipelines to increase the visibility of the software composition, increase automation and attest to their security practices.

The EO's 10 steps to securing your software supply chain

Secure software development environments using administratively separate build environments, controlling access, 2-factor authentication and by monitoring operations on the build environments.

Provide proof that your software was developed in a secure software development environment when requested by a purchaser.

Use automation to maintain trusted source code supply chains, thereby ensuring the integrity of the code.

Automation tools checking for known and potential vulnerabilities and fixes shall operate regularly.

The Purchaser may request proof of Automation and a summary report of risks and mitigations.

Maintain accurate and up-to-date data, provenance (i.e., origin) of software code or components, and controls on internal and third-party software components, tools, and services present in software development processes, and regularly perform audits and enforcement of these controls.

Participate in a vulnerability disclosure program that includes a reporting and disclosure process.

Attest to conformity with secure software development practices.

Attest to the integrity and provenance of OSS used within any portion of a product.

Cloudsmith is uniquely positioned to help Engineers secure their supply chain and meet the new requirements the US and UK government will be introducing. Cloudsmith provides an entirely managed cloud-native ‘single source of truth’ for all software and its dependencies, isolating and protecting you and your customers from supply chain attacks. Using continuous packaging (CP), we offer the observability and control to ensure that your software is always verified, packaged and ready to deliver.

Build and ship your software with Cloudsmith to secure your supply chain and comply with future regulations.
