AWS CodeArtifact is a fully managed artifact repository compatible with language-native package managers and build tools such as npm, Apache Maven, and pip. You can use CodeArtifact to share packages with development teams and pull packages. Packages can be pulled from both public and CodeArtifact repositories. You can also create an upstream relationship between a CodeArtifact repository and another repository, which effectively merges their contents from the point of view of a package manager client. AWS CodeArtifact Components Use the information in this guide to help you work with the following CodeArtifact components: Repository : A CodeArtifact repository contains a set of package versions, each of which maps to a set of assets, or files. Repositories are polyglot, so a single repository can contain packages of any supported type. Each repository exposes endpoints for fetching and publishing packages using tools like the npm CLI, the Maven CLI ( mvn ), and pip . Domain : Repositories are aggregated into a higher-level entity known as a domain. All package assets and metadata are stored in the domain, but are consumed through repositories. A given package asset, such as a Maven JAR file, is stored once per domain, no matter how many repositories it's present in. All of the assets and metadata in a domain are encrypted with the same customer master key (CMK) stored in AWS Key Management Service (AWS KMS). Each repository is a member of a single domain and can't be moved to a different domain. The domain allows organizational policy to be applied across multiple repositories, such as which accounts can access repositories in the domain, and which public repositories can be used as sources of packages. Although an organization can have multiple domains, we recommend a single production domain that contains all published artifacts so that teams can find and share packages across their organization. Package : A package is a bundle of software and the metadata required to resolve dependencies and install the software. CodeArtifact supports npm, PyPI, and Maven package formats. In CodeArtifact, a package consists of: A name (for example, webpack is the name of a popular npm package) An optional namespace (for example, @types in @types/node) A set of versions (for example, 1.0.0, 1.0.1, 1.0.2, etc.) Package-level metadata (for example, npm tags) Package version : A version of a package, such as @types/node 12.6.9. The version number format and semantics vary for different package formats. For example, npm package versions must conform to the Semantic Versioning specification. In CodeArtifact, a package version consists of the version identifier, metadata at the package version level, and a set of assets. Upstream repository : One repository is upstream of another when the package versions in it can be accessed from the repository endpoint of the downstream repository, effectively merging the contents of the two repositories from the point of view of a client. CodeArtifact allows creating an upstream relationship between two repositories. Asset : An individual file stored in CodeArtifact associated with a package version, such as an npm.tgz file or Maven POM and JAR files. CodeArtifact supports these operations: AssociateExternalConnection : Adds an existing external connection to a repository. CopyPackageVersions : Copies package versions from one repository to another repository in the same domain. CreateDomain : Creates a domain CreateRepository : Creates a CodeArtifact repository in a domain. DeleteDomain : Deletes a domain. You cannot delete a domain that contains repositories. DeleteDomainPermissionsPolicy : Deletes the resource policy that is set on a domain. DeletePackageVersions : Deletes versions of a package. After a package has been deleted, it can be republished, but its assets and metadata cannot be restored because they have been permanently removed from storage. DeleteRepository : Deletes a repository. DeleteRepositoryPermissionsPolicy : Deletes the resource policy that is set on a repository. DescribeDomain : Returns a DomainDescription object that contains information about the requested domain. DescribePackageVersion : Returns a PackageVersionDescription object that contains details about a package version. DescribeRepository : Returns a RepositoryDescription object that contains detailed information about the requested repository. DisposePackageVersions : Disposes versions of a package. A package version with the status Disposed cannot be restored because they have been permanently removed from storage. DisassociateExternalConnection : Removes an existing external connection from a repository. GetAuthorizationToken : Generates a temporary authorization token for accessing repositories in the domain. The token expires the authorization period has passed. The default authorization period is 12 hours and can be customized to any length with a maximum of 12 hours. GetDomainPermissionsPolicy : Returns the policy of a resource that is attached to the specified domain. GetPackageVersionAsset : Returns the contents of an asset that is in a package version. GetPackageVersionReadme : Gets the readme file or descriptive text for a package version. GetRepositoryEndpoint : Returns the endpoint of a repository for a specific package format. A repository has one endpoint for each package format: npm pypi maven GetRepositoryPermissionsPolicy : Returns the resource policy that is set on a repository. ListDomains : Returns a list of DomainSummary objects. Each returned DomainSummary object contains information about a domain. ListPackages : Lists the packages in a repository. ListPackageVersionAssets : Lists the assets for a given package version. ListPackageVersionDependencies : Returns a list of the direct dependencies for a package version. ListPackageVersions : Returns a list of package versions for a specified package in a repository. ListRepositories : Returns a list of repositories owned by the AWS account that called this method. ListRepositoriesInDomain : Returns a list of the repositories in a domain. PutDomainPermissionsPolicy : Attaches a resource policy to a domain. PutRepositoryPermissionsPolicy : Sets the resource policy on a repository that specifies permissions to access it. UpdatePackageVersionsStatus : Updates the status of one or more versions of a package. UpdateRepository : Updates the properties of a repository.

AWS AppConfig Use AWS AppConfig, a capability of AWS Systems Manager, to create, manage, and quickly deploy application configurations. AppConfig supports controlled deployments to applications of any size and includes built-in validation checks and monitoring. You can use AppConfig with applications hosted on Amazon EC2 instances, AWS Lambda, containers, mobile applications, or IoT devices. To prevent errors when deploying application configurations, especially for production systems where a simple typo could cause an unexpected outage, AppConfig includes validators. A validator provides a syntactic or semantic check to ensure that the configuration you want to deploy works as intended. To validate your application configuration data, you provide a schema or a Lambda function that runs against the configuration. The configuration deployment or update can only proceed when the configuration data is valid. During a configuration deployment, AppConfig monitors the application to ensure that the deployment is successful. If the system encounters an error, AppConfig rolls back the change to minimize impact for your application users. You can configure a deployment strategy for each application or environment that includes deployment criteria, including velocity, bake time, and alarms to monitor. Similar to error monitoring, if a deployment triggers an alarm, AppConfig automatically rolls back to the previous version. AppConfig supports multiple use cases. Here are some examples. Application tuning : Use AppConfig to carefully introduce changes to your application that can only be tested with production traffic. Feature toggle : Use AppConfig to turn on new features that require a timely deployment, such as a product launch or announcement. Allow list : Use AppConfig to allow premium subscribers to access paid content. Operational issues : Use AppConfig to reduce stress on your application when a dependency or other external factor impacts the system. This reference is intended to be used with the AWS AppConfig User Guide.

Amazon API Gateway Amazon API Gateway helps developers deliver robust, secure, and scalable mobile and web application back ends.

AWS CodeStar Connections This AWS CodeStar Connections API Reference provides descriptions and usage examples of the operations and data types for the AWS CodeStar Connections API. You can use the connections API to work with connections and installations. Connections are configurations that you use to connect AWS resources to external code repositories. Each connection is a resource that can be given to services such as CodePipeline to connect to a third-party repository such as Bitbucket. For example, you can add the connection in CodePipeline so that it triggers your pipeline when a code change is made to your third-party code repository. Each connection is named and associated with a unique ARN that is used to reference the connection. When you create a connection, the console initiates a third-party connection handshake. Installations are the apps that are used to conduct this handshake. For example, the installation for the Bitbucket provider type is the Bitbucket app. When you create a connection, you can choose an existing installation or create one. When you want to create a connection to an installed provider type such as GitHub Enterprise Server, you create a host for your connections. You can work with connections by calling: CreateConnection, which creates a uniquely named connection that can be referenced by services such as CodePipeline. DeleteConnection, which deletes the specified connection. GetConnection, which returns information about the connection, including the connection status. ListConnections, which lists the connections associated with your account. You can work with hosts by calling: CreateHost, which creates a host that represents the infrastructure where your provider is installed. DeleteHost, which deletes the specified host. GetHost, which returns information about the host, including the setup status. ListHosts, which lists the hosts associated with your account. You can work with tags in AWS CodeStar Connections by calling the following: ListTagsForResource, which gets information about AWS tags for a specified Amazon Resource Name (ARN) in AWS CodeStar Connections. TagResource, which adds or updates tags for a resource in AWS CodeStar Connections. UntagResource, which removes tags for a resource in AWS CodeStar Connections. For information about how to use AWS CodeStar Connections, see the Developer Tools User Guide.
