docs(marketplace): add Application Marketplace section - #672
Conversation
Document the PackageSource-based marketplace: publishing a repository (init/validate/push and the community index), connecting a repository to a cluster (search/tap/add and the dashboard), and a full cozypkg command reference. Lives under docs/next/ as an upcoming-release feature. Signed-off-by: IvanHunters <xorokhotnikov@gmail.com>

Tapped repositories keep their own declared PackageSource name instead of a community. prefix, and a clash with a core component is rejected at tap time. Drops the reserved-name note and the --allow-reserved-names flag, updates the CLI examples to declared names, and describes the collision behaviour and the label-based untap.

Kubernetes object names DNS subdomain metadata.name underscores invalid official documentation
💡 Result:
In Kubernetes, most object names—specified in the metadata.name field—must adhere to the DNS subdomain name standard as defined in RFC 1123 [1]. Under this standard, underscores (_) are invalid [1][2][3]. Valid metadata.name values must [1]: - Contain only lowercase alphanumeric characters, hyphens (-), or dots (.). - Start and end with an alphanumeric character. - Be no more than 253 characters in length. This restriction exists because Kubernetes object names are frequently used as hostnames or within DNS records for service discovery, which requires compliance with DNS naming conventions [1][4][5]. It is important to distinguish this from Kubernetes labels, which have different validation rules [6]. Label keys and values do permit the use of underscores [7][6]. If you encounter a validation error when creating an object, ensure your metadata.name does not contain underscores and follows the DNS subdomain format [2][3].

Make the tap validation exception explicit.
Line 80 says that tapping validates the artifact unconditionally, but --skip-validate at Line 87 disables validation. Rewrite this sentence to say “by default” and state what validation remains when the flag is used.
Suggested wording
- Tapping is idempotent and validates the artifact's structure but does not verify its cosign signature.
+ Tapping is idempotent. By default, it validates the artifact's structure; `--skip-validate` bypasses that check. Tapping does not verify its cosign signature.📝 Committable suggestion

Carefully review the code before committing. Ensure that it accurately replaces the highlighted code, contains no missing lines, and has no issues with indentation. Thoroughly test & benchmark the code to ensure it meets the requirements.

Describe add as creating Package resources.
PackageSource defines what is available. Package selects a variant and represents what is deployed. The command reference should say that cozypkg add installs packages from PackageSource resources and creates Package resources, not that it installs a PackageSource. (cozystack.io)

site:github.com/cozystack/cozystack cozypkg "dot" "--installed" "--components"
💡 Result:
The command cozypkg dot --installed --components is part of the Cozystack CLI tool, which is used for managing packages and package sources within a Cozystack environment [1]. The cozypkg dot command specifically generates a dependency graph of the packages in the cluster [1]. When you use the provided flags, the behavior is as follows: --installed: This flag tells the tool to build the dependency graph based on the currently installed Package resources in the cluster, rather than looking at all available PackageSource resources [1]. --components: This flag instructs the tool to include component-level detail in the dependency graph, such as variant-specific edges [1]. The tool emits the resulting graph in Graphviz DOT format, which can then be visualized or processed by other tools [1]. The cozypkg CLI itself was introduced to provide an interface for interacting with Package and PackageSource resources, offering functionality for adding, deleting, listing, and analyzing package dependencies [1].

cozystack/cozystack pull request 1756 cozypkg dot kubeconfig
💡 Result:
Cozystack pull request #1756 introduced the initial version of the cozypkg CLI tool, which was designed to manage Package and PackageSource resources within the Cozystack ecosystem [1]. Key features included in PR #1756: - Interactive commands to add, delete, and list packages, including dependency resolution and topological installation ordering [1]. - A dependencies command capable of emitting Graphviz DOT graphs to visualize package and component relationships [1]. - Standard CLI flags, including --kubeconfig, to allow users to specify the path to their Kubernetes configuration file [1]. Shortly after its introduction, the cozypkg tool was renamed to cozyhr in pull request #1763 to better reflect its function and branding as a wrapper around Helm and Flux CD [2][3]. Consequently, documentation and tooling now refer to this utility as cozyhr [4][2].

site:github.com/cozystack/cozystack "cozypkg dot" "--kubeconfig"
💡 Result:
The command cozypkg dot --kubeconfig is used within the Cozystack ecosystem to generate a Graphviz DOT representation of package and component dependencies [1]. The cozypkg tool is a CLI utility for managing Package and PackageSource resources in Cozystack [1][2]. When running the dot subcommand, the tool builds a dependency graph from the cluster's resources and outputs it in the DOT format [1]. Key details regarding the --kubeconfig flag and the command include: - Purpose: The --kubeconfig flag allows you to specify the path to your Kubernetes configuration file [1]. If it is not provided, the tool defaults to using the file located at ~/.kube/config or the value set in the KUBECONFIG environment variable [1]. - Functionality: The dot command analyzes PackageSource and Package resources [1]. It supports various options to customize the output, such as filtering for installed packages (--installed) or including component-level detail (--components) [1]. - Underlying implementation: The command utilizes github.com/emicklei/dot to generate the graph, which can include variant-specific edges and account for both local and external package references [1]. In addition to dot, cozypkg provides several other management commands, such as add, del, list, and dependencies [1].

Define the merge lane for every entry field.
The two-lane policy does not assign homepage or tags changes to either lane. It also requires a “new artifact” for a description-only change, although that change does not identify a new artifact. State the exact review and validation rule for these edits so contributors and the index gate use the same contract.

What
Adds a new "Application Marketplace" section under
docs/next/documenting the PackageSource-based marketplace and thecozypkgCLI:_index.md): the marketplace model, key objects (PackageSource,ApplicationDefinition,Tap,OCIRepository), thecommunity.namespace, and the trust model. Cross-links the legacy External Apps page.Why
The marketplace is a new way to extend the application catalog with external repositories. It has no user-facing documentation yet.
Notes
docs/next/(the unreleased trunk), so it is excluded from production builds until the feature ships. It documents functionality still in review upstream (feat(marketplace): community marketplace for External-Apps repositories cozystack#3940); the pages track that work and should land alongside the release that includes it.Summary by CodeRabbit
