Additional resources Section 3.1, "Viewing artifacts using the Service Registry web console" Section 3.3, "Configuring content rules using the Service Registry web console" Chapter 10, Service Registry content rule reference 3.3. Configuring content rules using the Service Registry web console You can use the Service Registry web console to configure optional rules to prevent invalid or incompatible content from being added to Service Registry. All configured artifact-specific rules or global rules must pass before a new artifact version can be uploaded to Service Registry. Configured artifact-specific rules override any configured global rules. This section shows a simple example of configuring global and artifact-specific rules. Prerequisites Service Registry is installed and running in your environment. You are logged in to the Service Registry web console: http://MY_REGISTRY_URL/ui Artifacts have been added to Service Registry using the web console, command line, Maven plug-in, or a Java client application. When role-based authorization is enabled, you have administrator access for global rules and artifact-specific rules, or developer access for artifact-specific rules only. Procedure On the Artifacts tab, browse the list of artifacts in Service Registry, or enter a search string to find an artifact. You can select from the list to search by specific criteria such as artifact name, group, labels, or global ID. Click an artifact to view its version details and content rules. In Artifact-specific rules , click Enable to configure a validity, compatibility, or integrity rule for artifact content, and select the appropriate rule configuration from the list. For example, for Validity rule , select Full . Figure 3.3. Artifact content rules in Service Registry web console To access global rules, click the Global rules tab. Click Enable to configure global validity, compatibility, or integrity rules for all artifact content, and select the appropriate rule configuration from the list. To disable an artifact rule or global rule, click the trash icon to the rule.

Generating client SDKs for OpenAPI artifacts using the Service Registry web console You can use the Service Registry web console to configure, generate, and download client software development kits (SDKs) for OpenAPI artifacts. You can then use the generated client SDKs to build your client applications for specific platforms based on the OpenAPI. Service Registry generates client SDKs for the following programming languages: C# Go Java PHP Python Ruby Swift TypeScript Note Client SDK generation for OpenAPI artifacts runs in your browser only, and cannot be automated by using an API. You must regenerate the client SDK each time a new artifact version is added in Service Registry. Prerequisites Service Registry is installed and running in your environment. You are logged in to the Service Registry web console: http://MY_REGISTRY_URL/ui An OpenAPI artifact has been added to Service Registry using the web console, command line, Maven plug-in, or a Java client application. Procedure On the Artifacts tab, browse the list of artifacts stored in Service Registry, or enter a search string to find a specific OpenAPI artifact. You can select from the list to search by criteria such as name, group, labels, or global ID. Click the OpenAPI artifact in the list to view its details. In the Version metadata section, click Generate client SDK , and configure the following settings in the dialog: Language : Select the programming language in which to generate the client SDK, for example, Java . Generated client class name : Enter the class name for the client SDK, for example, MyJavaClientSDK. Generated client package name : Enter the package name for the client SDK, for example, io.my.example.sdk Click Show advanced settings to configure optional comma-separated lists of path patterns to include or exclude: Include path patterns : Enter specific paths to include when generating the client SDK, for example, **/.*, **/my-path/* . If this field is empty, all paths are included. Exclude path patterns : Enter specific paths to exclude when generating the client SDK, for example, **/my-other-path/* . If this field is empty, no paths are excluded. Figure 3.4. Generate a Java client SDK in Service Registry web console When you have configured the settings in the dialog, click Generate and download . Enter a file name for the client SDK in the dialog, for example, my-client-java.zip , and click Save to download. Additional resources Service Registry uses Kiota from Microsoft to generate the client SDKs. For more information, see the Kiota project in GitHub . For more details and examples of using the generated SDKs to build client applications, see the Kiota documentation . 3.5. Changing an artifact owner using the Service Registry web console As an administrator or as an owner of a schema or API artifact, you can use the Service Registry web console to change the artifact owner to another user account. For example, this feature is useful if the Artifact owner-only authorization option is set for the Service Registry instance on the Settings tab so that only owners or administrators can modify artifacts. You might need to change owner if the owner user leaves the organization or the owner account is deleted. Note The Artifact owner-only authorization setting and the artifact Owner field are displayed only if authentication was enabled when the Service Registry instance was deployed. For more details, see Installing and deploying Service Registry on OpenShift . Prerequisites The Service Registry instance is deployed and the artifact is created. You are logged in to the Service Registry web console as the artifact's current owner or as an administrator: http://MY_REGISTRY_URL/ui Procedure On the Artifacts tab, browse the list of artifacts stored in Service Registry, or enter a search string to find the artifact. You can select from the list to search by criteria such as name, group, labels, or global ID. Click the artifact that you want to reassign. In the Version metadata section, click the pencil icon to the Owner field. In the New owner field, select or enter an account name. Click Change owner . Additional resources Installing and deploying Service Registry on OpenShift 3.6. Configuring Service Registry instance settings using the web console As an administrator, you can use the Service Registry web console to configure dynamic settings for Service Registry instances at runtime. You can manage configuration options for features such as authentication, authorization, and API compatibility. Note Authentication and authorization settings are only displayed in the web console if authentication was already enabled when the Service Registry instance was deployed. For more details, see the Installing and deploying Service Registry on OpenShift . Prerequisites The Service Registry instance is already deployed. You are logged in to the Service Registry web console with administrator access: http://MY_REGISTRY_URL/ui Procedure In the Service Registry web console, click the Settings tab. Select the settings that you want to configure for this Service Registry instance: Table 3.1. Authentication settings Setting Description HTTP basic authentication Displayed only when authentication is already enabled. When selected, Service Registry users can authenticate using HTTP basic authentication, in addition to OAuth. Not selected by default. Table 3.2. Authorization settings Setting Description Anonymous read access Displayed only when authentication is already selected. When selected, Service Registry grants read-only access to requests from anonymous users without any credentials. This setting is useful if you want to use this instance to publish schemas or APIs externally. Not selected by default. Artifact owner-only authorization Displayed only when authentication is already enabled. When selected, only the user who created an artifact can modify that artifact. Not selected by default. Artifact group owner-only authorization Displayed only when authentication is already enabled and Artifact owner-only authorization is selected. When selected, only the user who created an artifact group has write access to that artifact group, for example, to add or remove artifacts in that group. Not selected by default. Authenticated read access Displayed only when authentication is already enabled. When selected, Service Registry grants at least read-only access to requests from any authenticated user regardless of their user role. Not selected by default. Table 3.3. Compatibility settings Setting Description Legacy ID mode (compatibility API) When selected, the Confluent Schema Registry compatibility API uses globalId instead of contentId as an artifact identifier. This setting is useful when migrating from legacy Service Registry instances based on the v1 Core Registry API. Not selected by default. Table 3.4. Web console settings Setting Description Download link expiry The number of seconds that a generated link to a .zip download file is active before expiring for security reasons, for example, when exporting artifact data from the instance. Defaults to 30 seconds. UI read-only mode When selected, the Service Registry web console is set to read-only, preventing create, read, update, or delete operations. Changes made using the Core Registry API are not affected by this setting. Not selected by default. Table 3.5. Additional properties Setting Description Delete artifact version When selected, users are permitted to delete artifact versions in this instance by using the Core Registry API. Not selected by default. Additional resources Installing and deploying Service Registry on OpenShift 3.7. Exporting and importing data using the Service Registry web console As an administrator, you can use the Service Registry web console to export data from one Service Registry instance, and import this data into another Service Registry instance. You can use this feature to easily migrate data between different instances. The following example shows how to export and import existing data in a .zip file from one Service Registry instance to another instance. All of the artifact data contained in the Service Registry instance is exported in the .zip file. Note You can import only Service Registry data that has been exported from another Service Registry instance. Prerequisites Service Registry instances have been created as follows: The source instance that you are exporting from contains at least one schema or API artifact The target instance that you are importing into is empty to preserve unique IDs You are logged into the Service Registry web console with administrator access: http://MY_REGISTRY_URL/ui Procedure In the web console for the source Service Registry instance, view the Artifacts tab. Click the options icon (three vertical dots) to Upload artifact , and select Download all artifacts (.zip file) to export the data for this Service Registry instance to a .zip download file. In the the web console for the target Service Registry instance, view the Artifacts tab. Click the options icon to Upload artifact , and select Upload multiple artifacts . Drag and drop or browse to the .zip download file that you exported earlier. Click Upload and wait for the data to be imported.
