View Browser App

This App runs a webserver and exposes two endpoints:



Alternatively, one can click on the 'Open App' button from the UI to get the <app-ip>:<node-port> part automatically.

This is to demonstrate how to write an App for Cohesity's App Platform. It also servers as an example for consumption of Cohesity's App and Management Golang SDKs.


In order to successfully build and run Sample App, you are required to have the following setup in your system: Golang

After installing GO, use go get to install the sample app: viewbrowser:

go get

If this does not work. Follow below steps 1. go mod init view_browser_exec (Run this command in cohesity-appspec/sampleapp/viewbrowser ) 2. go build . 3. Copy generated view_browser_exec binary file to deployment folder

This will also get all the dependencies including Cohesity App and Management Go SDKs.

Container Environment Parameters

The App Container Environment has the following parameters initialized by Cohesity App Server.

HOST_IP  # The Host IP on which the container is running.
APPS_API_ENDPOINT_IP # Cohesity App Server IP.
APPS_API_ENDPOINT_PORT # Cohesity App Server Port.
APP_AUTHENTICATION_TOKEN # Authetication Token to make Cohesity App API calls. 

We use the above variables in various use cases to initialize and make call to App server.

Packaging the App

Please refer to this section to containerize this application.

Uploading the App to Cohesity Marketplace

  • Login to DevPortal.
  • Go to Build App -> Container App.
  • Insert all details in the form.
  • Upload the docker images and .yaml file.
  • You can submit the application for review/download the .pkg file and run it on a Cohesity cluster.

Testing the App

  • Login to your Cohesity cluster.
  • Go to Marketplace -> My Apps.
  • Click on the Upload button (present on the top right section of the page).
  • Select the .pkg file which you got from the DevPortal.
  • Click on Upload and Install.
  • Click on the 'Run App' button will show up which will show up soon after the app installs.

Using App & Management SDK

The Sample App uses Cohesity provides App and Management SDKs to make it easy to write Apps onto Cohesity Management Platform.

Importing the packages:

import (

Init the App Client:

apiEndpointIp = os.Getenv("APPS_API_ENDPOINT_IP")
apiEndpointPort = os.Getenv("APPS_API_ENDPOINT_PORT")
appAuthenticationToken = os.Getenv("APP_AUTHENTICATION_TOKEN")
appClient = CohesityAppSdk.NewAppSdkClient(appAuthenticationToken,

App Client in action:

// Get App Settings.
appSettings, err := appClient.Settings().GetAppSettings()

Get ManagementAccessToken:

managementTokenResponse, err := appClient.TokenManagement().CreateManagementAccessToken() 
managementAccessToken.AccessToken = managementTokenResponse.AccessToken
managementAccessToken.TokenType = managementTokenResponse.TokenType


managementClient = ManagementSdk.NewCohesityClientWithToken(apiEndpointIp, 

Using Management Client to Cohesity Views:

 viewsResult, err := managementClient.Views().GetViews(viewNames, viewBoxNames,
            matchPartialNames, maxCount, maxViewId, includeInactive, tenantIds,
            allUnderHierarchy, viewBoxIds, jobIds, sortByLogicalUsage, matchAliasNames)

Using Management Client to Mount View:

err := appClient.Mount().CreateMount(&mountOptions)
