App42 DevOps

App42 DevOps

To automate and fasten DevOps process (development, build,test and deploy), we are providing integration and automatic wiring of various DevOps tools mentioned below:

  • Chef (systems and Cloud Infrastructure framework or Configuration Management tool) that automates the management of the infrastructure through recipes and cookbooks.
  • Puppet is a Configuration Management tool that allows you to define the state of your IT infrastructure and then automatically enforces the desired state.
  • Jenkins that provides Continuous Integration services for software development.
  • Artifactory(Jfrog) is a Binary Repository Management tool. It helps the DevOps teams to manage, host and control the flow of binary artifacts.
  • JMeter that can be used as a load testing tool for analyzing and measuring the performance of services.
  • Selenium which is a functional testing tool for web applications.

Prerequisite

Key Pair Generation

As part of DevOps solution, we are providing a public/private key authentication to provide secure shell connections.
Steps to create Key-Pair on App42 DevOps:

  • 1.Login to http://devopshq.shephertz.com.
  • 2.Go to Key Section on left menu.
  • 3.Click on Create Key Pair.
  • 4.Enter Key Name and click on Submit button.
    Key-Pair Creation
  • 5. It will prompt the user to save private key.
    Save Private Key
    • Note : Once Key Pair has been created, the public and private key can be used by the user to login into their DevOps VM or standalone VM with username as “paasuser”. While creating the DevOps environment or standalone tools,the public key will be transferred to the VM and the private key is shared with user (described in step 5 above).

Setup DevOps Environment

To setup a complete DevOps environment on App42 DevOps, follow the below steps:

  • 1. Login to http://devopshq.shephertz.com.
  • 2. Click on DevOps on left menu.
  • 3. On Create Environment page, enter the name of Setup.
    • Choose the key pair with which setup has to be created.
    • Select the tools with the required configuration:
      • i.Continuous Integration :  Jenkins.
                                                     Add Master / Slaves (addition of slaves is optional)
      • ii.Configuration Management :   Chef or Puppet.
      • iii.Binary Repository :   Artifactory(Jfrog).

        • Create DevOps Environment-Select tools and configuration
  • 4.Click on Submit button.
  • 5.Once Environment gets created, user will have an option to create Application Nodes for the setup.
    Option to Create Application Nodes
  • 6.If user Select “Yes”, then he will be redirected to the Create Application Node page.
    • Once Application nodes gets created,
    Note : In case of Puppet as Configuration Management tool, the Application nodes will get signed automatically with the Puppet Master present in user’s DevOps Setup.
  • 7.If User Select “NO”, then he will be redirected to the Manage Environment page.
  • 8.User can create and attach Application Nodes separately from DevOps -> Application Nodes section.

Setting up Application Nodes

User can create Application Nodes from DevOps -> Application Nodes section.

If user is creating Application Nodes with DevOps setup, then skip below steps(1,2,3).
  • 1.Choose Setup and Click on Create Application Node.
    Create Application Node
  • 2.Enter the required fields:
    • DevOps Environment: From here, choose Environment with which nodes are required to be associated.
    • Key Pair: Choose key (which you have created in above steps) from Key Pair drop down for your Application Nodes or create new key from “Create Key Pair”.
    • Node: Enter the name of your node. To create more than 1 node, click on Add Node.
    • Click on Submit.
      Configure Application Node
      This will create Application Nodes which will associate with the choosen setup.
  • 3.Once Application nodes gets created,

Manage DevOps Environment

  • 1. View DevOps environment on the DevOps > Manage Environment page.
    DevOps Setup
  • 2. Manage DevOps environment from Manage Environment page.
    Manage DevOps Setup
  • 3.Click on Manage to see the different tools configured for DevOps Environment.

    Note : Start, Stop, Restart and Delete will be applied to entire setup.

      There are 2 options for users to perform start, stop and restart on tools:

    • HARD - will be applied to VM as well as on application.
    • SOFT – will be applied only on application.

    For eg. : If user chooses HARD STOP then the VM as well as the Application, both will stop and they will go into HARD STOP state. Now to start, user need to HARD START them. Similarly, if a resource is in SOFT STOP state, then user can start it with SOFT START .

  • 5.  Click on Launch to open the respective Management Console for the tool.
  • 6.  Click on Manage to perform various operations & update configuration for the tool.

  • 7.  Click on Dashboard on left menu to view setup.
  • 8.  Click on View Health to view the health for virtual machine.
