Docker Hub Destination

Docker Hub
Create a Docker Hub Destination
-
Click the + icon on the Nexset that will be sent to the Docker Hub destination, and select the Send to Destination option from the menu.
-
Select the Docker Hub connector from the list of available destination connectors. Then, select the credential that will be used to connect to the Docker Hub organization, and click Next; or, create a new Docker Hub credential for use in this flow.
-
In Nexla, Docker Hub destinations can be created using pre-built endpoint templates, which expedite destination setup for common Docker Hub endpoints. Each template is designed specifically for the corresponding Docker Hub API endpoint, making destination configuration easy and efficient.
• To configure this destination using a template, follow the instructions in Configure Using a Template.Docker Hub destinations can also be configured manually, allowing you to send data to Docker Hub endpoints not included in the pre-built templates or apply further customizations to exactly suit your needs.
• To configure this destination manually, follow the instructions in Configure Manually.
Configure Using a Template
Nexla provides pre-built templates that can be used to rapidly configure destinations to send data to common Docker Hub endpoints. Each template is designed specifically for the corresponding Docker Hub API endpoint, making destination setup easy and efficient.
-
To configure this destination using a template, select the endpoint to which data will be sent from the Endpoint pulldown menu. Then, click on the template in the list below to expand it, and follow the instructions to configure additional endpoint settings.
Configure Manually
Docker Hub destinations can be manually configured to send data to any valid Docker Hub API endpoint. Using manual configuration, you can also configure Nexla to automatically send the response received from the Docker Hub API after each call to a new Nexla webhook data source.
API Method
-
To manually configure this destination, select the Advanced tab at the top of the configuration screen.
-
Select the API method that will be used for calls to the Docker Hub API from the Method pulldown menu. Common methods for Docker Hub write operations include:
- POST: For creating new resources (repositories, tokens, teams, invitations).
- PUT: For replacing or fully updating an existing resource (e.g., updating a member's organization role).
- PATCH: For partial updates to an existing resource (e.g., updating a token's label or active state).
- DELETE: For permanently removing a resource (e.g., deleting a token or team).
Data Format
- Select the format in which the Nexset data will be sent to the Docker Hub API from the Content Format pulldown menu. Docker Hub's API accepts and returns data in JSON format — select JSON as the content format. Nexla will automatically convert the Nexset data to JSON for each API call.
API Endpoint URL
- Enter the URL of the Docker Hub API endpoint to which you want to send the Nexset data in the URL field. All Docker Hub API endpoints use the base URL
https://hub.docker.com/v2/. For update or delete operations, include the resource identifier at the end of the URL. For example:https://hub.docker.com/v2/namespaces/myorg/repositories— creates a repository undermyorg.https://hub.docker.com/v2/orgs/myorg/members/username— updates a member inmyorg.https://hub.docker.com/v2/access-tokens/token-uuid— updates or deletes a specific personal access token.
The complete Docker Hub API reference, including all available endpoint URLs and their required parameters, is available at https://docs.docker.com/reference/api/hub/latest/.
Request Headers
-
If Nexla should include any additional request headers in API calls to this destination, enter the headers & corresponding values as comma-separated pairs in the Request Headers field (e.g.,
header1:value1,header2:value2).You do not need to include the
Authorizationheader — Nexla automatically includes the bearer token from your Docker Hub credential in every API request.
Exclude Attributes from the Call
-
If any record attributes in the Nexset should be omitted when sending data to this Docker Hub destination, select the attributes from the Exclude Attributes pulldown menu.
-
Any number of attributes can be selected for exclusion, and all excluded attributes will be shown in the field. To remove an attribute from the list, click the X icon next to the attribute name.
Record Batching
-
If records should be sent to this destination in batched API calls, check the box next to Would you like to batch your records together? to enable record batching.
-
Enter the maximum number of records that should be batched together in a single API call in the Batch Size field. By default, this value is set to
100. -
Select the algorithm that will be used to group records into batches from the Grouping Algorithm pulldown menu. The sample request shown in the panel on the right will be updated to reflect the current batching settings. Some algorithms require additional settings—click on an algorithm listed below to view instructions for configuring these settings.
Response Webhook
Nexla can automatically send the response received from the Docker Hub API after each call to a new Nexla webhook data source. This option allows you to keep track of the status of each API call and any additional information returned after each call — for example, to capture the generated token value returned by the Create a personal access token endpoint, or to capture the created repository ID for downstream processing.
- To enable this option, check the box next to Would you like to process the API response as a Nexla Webhook source?.
