API reference

{: #api}

You can use the {{site.data.keyword.codeenginefull}} API to create and manage your {{site.data.keyword.codeengineshort}} entities. To use the CLI, see Setting up the CLI. {: shortdesc}

Retrieve your Kubernetes configuration with REST API

{: #api-rest}

To retrieve your Kubernetes configuration with REST API,

  1. Authenticate with {{site.data.keyword.iamlong}} (IAM) to receive an IAM access token.
  2. Query the {{site.data.keyword.cloud_notm}} catalog and the {{site.data.keyword.cloud_notm}} Resource controller to receive a GUID for your project.
  3. Use the {{site.data.keyword.codeenginefull_notm}} API to receive a Kubernetes configuration.

Authenticate with {{site.data.keyword.iamshort}}

{: #api-iam}

Create your {{site.data.keyword.cloud_notm}} IAM access token{: external} by making a POST request to https://iam.cloud.ibm.com/identity/token.

Determine the GUID of your {{site.data.keyword.codeengineshort}} project

{: #api-guid}

Determine the GUID of your {{site.data.keyword.codeengineshort}} project by querying the {{site.data.keyword.cloud_notm}} catalog and the {{site.data.keyword.cloud_notm}}. As this GUID does not change, you need to do this step only one time. If you already know your {{site.data.keyword.codeengineshort}} project GUID, you can skip this step.

CLI

{: #api-guid-cli}

  1. Log in into {{site.data.keyword.cloud_notm}} and target a region, account, and resource group.

    ibmcloud login target -r REGION -c ACCOUNT_ID -g RESOURCE_GROUP

    {: pre}

  2. Run the ibmcloud resource command.

    ibmcloud resource service-instances --service-name codeengine --long

    {: pre}

Identify the service instance that represents your {{site.data.keyword.codeengineshort}} project and determine the GUID from the output.

REST API

{: #api-guid-restapi}

Before you begin, you must have the access_token from the previous step.

  1. Use following {{site.data.keyword.cloud_notm}} catalog API method: Returns parent catalog entries{: external}.

    Example output

    curl -X GET \
  'https://globalcatalog.cloud.ibm.com/api/v1?include=*&q=name:codeengine+active:true' \
  -H 'Authorization: Bearer ACCESS_TOKEN'

    {: pre}

    Identify the unique resource ID in the resources list. The field name is ID and the JSON path is resources[].id.

  2. Query the {{site.data.keyword.cloud_notm}} Resource controller with the {{site.data.keyword.cloud_notm}} Resource controller API method Get a list of all resource instances{: external}. You must have the {{site.data.keyword.codeengineshort}} project name, the region that your project resides, and the unique resource ID of {{site.data.keyword.codeengineshort}} in the global catalog. Use the name of your {{site.data.keyword.codeengineshort}} project as the query parameter.

    Example output

    curl -X GET \
    'https://resource-controller.cloud.ibm.com/v2/resource_instances?name=MY_PROJECT&resource_id=RESOURCE_ID' \
    -H 'Authorization: Bearer ACCESS_TOKEN'

    {: pre}

    Identify the {{site.data.keyword.codeengineshort}} project from your region in the result list. Find the guid output to use in the next steps.

Query the IBM {{site.data.keyword.codeengineshort}} API

{: #api-query-api}

Before you begin, you must have the following information.

  • The access_token and refresh_token from previous steps.
  • The guid of your {{site.data.keyword.codeengineshort}} project.
  • The region in which your {{site.data.keyword.codeengineshort}} project is located.

Use the get kubeconfig for the specified project{: external} {{site.data.keyword.codeengineshort}} API method to get the Kubernetes configuration.

Example output

{: #api-query-example}

curl -X GET \
    'https://resource-controller.cloud.ibm.com/v2/resource_instances?name=MY_PROJECT&resource_id=RESOURCE_ID' \
    -H 'Authorization: Bearer ACCESS_TOKEN'

{: pre}

Retrieving your Kubernetes configuration with the {{site.data.keyword.codeengineshort}} CLI

{: #api-cli}

  1. Log in into {{site.data.keyword.cloud_notm}} and target a region, account, and resource group.

    ibmcloud login target -r REGION -c ACCOUNT_ID -g RESOURCE_GROUP

    {: pre}

  2. Create your {{site.data.keyword.codeengineshort}} project:

    ibmcloud ce project create --name PROJECT

    {: pre}

  3. Select your {{site.data.keyword.codeengineshort}} project as the current context and append the project to the default Kubernetes configuration file.

    ibmcloud ce project select --name PROJECT --kubecfg

    {: pre}

Now you are ready to use kubectl commands with your project.
