The parent in whose context the Deployments are listed. The *  parent value is in the format: *  'projects/{project_id}/locations/{location}'. */// const parent = 'abc123'/** *  When requesting a page of resources, 'page_size' specifies number of *  resources to return. If unspecified or set to 0, all resources will be *  returned. */// const pageSize = 1234/** *  Token returned by previous call to 'ListDeployments' which specifies the *  position in the list from where to continue listing the resources. */// const pageToken = 'abc123'/** *  Lists the Deployments that match the filter expression. A filter *  expression filters the resources listed in the response. The expression *  must be of the form '{field} {operator} {value}' where operators: '<', '>', *  '<=', '>=', '!=', '=', ':' are supported (colon ':' represents a HAS *  operator which is roughly synonymous with equality). {field} can refer to a *  proto or JSON field, or a synthetic field. Field names can be camelCase or *  snake_case. *  Examples: *  - Filter by name: *    name = "projects/foo/locations/us-central1/deployments/bar *  - Filter by labels: *    - Resources that have a key called 'foo' *      labels.foo:* *    - Resources that have a key called 'foo' whose value is 'bar' *      labels.foo = bar *  - Filter by state: *    - Deployments in CREATING state. *      state=CREATING */// const filter = 'abc123'/** *  Field to use to sort the list. */// const orderBy = 'abc123'// Imports the Config libraryconst {ConfigClient} = require('@google-cloud/config').v1;// Instantiates a clientconst configClient = newConfigClient();async function callListDeployments() {  // Construct request  const request = {    parent,  };  // Run request  const iterable = await configClient.listDeploymentsAsync(request);  for await (const response of iterable) {    console.log(response);  }}callListDeployments();
