ServiceNow API Jenkins Plugin

This is a Jenkins plugin that allows a workflow step to automatically build API requests for the ServiceNow API and return appropriately parsed values based on the type of API called.

It defines a set of configuration values that can be used to identify the ServiceNow instance information and configure the API requests.

Jenkins-ServiceNow Change Workflow

The central idea for this plugin is to allow the deployment process through Jenkins to manageeverything about a service now change. One of the first pieces from ServiceNow this plugin uses is the idea of a standard change producer. This allows teams to build change requests templates that their application uses when it is deployed.

Once these templates are created, the goal is to allow Jenkins to carry out everything necessary for the change request, from creation and data gathering (test results, commit messages, and approvals), to managing the change tasks within the change itself, all the way to closing the change request once it completes. This is implemented using the Step mechanism that is available to the Jenkins pipeline.

A standard change workflow can vary based on the ServiceNow implementation at your company. In general, there are pre-tasks, implementation tasks, and post-tasks, as well as change metadata. This plugin provides interfaces to interact with these tasks, update change metadata, proceed task workflows, and attach information from the build to proper locations within the context of a change request.

Plugin Usage

All Steps

Required Parameters

Every step must provide these two arguments in order to connect to the ServiceNow instance

• serviceNowConfiguration
  • instance - Instance of service-now to connect to (https://.service-now.com)
• credentialsId - Jenkins credentials for Username with Password credentials or Vault Role Credentials, if including vaultConfiguration below

Optional Parameters

vaultConfiguration

• url - Vault url
• path - Vault path to get authentication values

serviceNow_createChange

Required Parameters

serviceNowConfiguration

• producerId - Producer ID of the standard change to create

Response

result

• sys_id
• number
• record
• redirect_portal_url
• redirect_url
• table
• redirect_to

Example

Create a service-now change and capture the sys_id and change number

def response = serviceNow_createChange serviceNowConfiguration: [instance: 'exampledev', producerId: 'ls98y3khifs8oih3kjshihksjd'], credentialsId: 'jenkins-vault', vaultConfiguration: [url: 'https://vault.example.com:8200', path: 'secret/for/service_now/']
def jsonSlurper = new JsonSlurper()
def createResponse = jsonSlurper.parseText(response.content)
def sysId = createResponse.result.sys_id
def changeNumber = createResponse.result.number

serviceNow_updateChangeItem

Required Parameters

serviceNowItem

• table - Table of the item to be updated (ex. change_request, change_task)
• sysId - SysId of the item to be updated
• body - Json message (as String) of the properties and values to be updated

Response

result

Example

Update a service-now change with a short description and description

def messageJson = new JSONObject()
messageJson.putAll([
                short_description: 'My change',
                description: 'My longer description of the change'
        ])
def response = serviceNow_updateChangeItem serviceNowConfiguration: [instance: 'exampledev'], credentialsId: 'jenkins-vault', serviceNowItem: [table: 'change_request', sysId: 'adg98y29thukwfd97ihu23', body: messageJson.toString()], vaultConfiguration: [url: 'https://vault.example.com:8200', path: 'secret/for/service_now/']

serviceNow_getChangeState

Required Parameters

serviceNowItem

• sysId - SysId of the change request

Response

state - String representation of the state (@see ServiceNowStates)

Example

Get the current state of a service-now change

def response = serviceNow_UpdateChangeItem serviceNowConfiguration: [instance: 'exampledev'], credentialsId: 'jenkins-vault', serviceNowItem: [sysId: 'adg98y29thukwfd97ihu23'], vaultConfiguration: [url: 'https://vault.example.com:8200', path: 'secret/for/service_now/']
echo response //NEW

serviceNow_getCTask

Required Parameters

serviceNowItem

• sysId - SysId change to get CTask from
• ctask - String description of the ctask for querying (optional)

Response

result - an array of results

• sys_id
• number
• short_description

Example

Get ctask of a service-now change

def response = serviceNow_getCTask serviceNowConfiguration: [instance: 'exampledev'], credentialsId: 'jenkins-vault', serviceNowItem: [sysId: 'agsdh0wehosid9723h30h', ctask: 'UAT_TESTING'], vaultConfiguration: [url: 'https://vault.example.com:8200', path: 'secret/for/service_now/']
def ctaskResponse = new JsonSlurper().parseText(response.content)
def ctaskSysId = createResponse.result[0].sys_id
def ctaskNumber = createResponse.result[0].number

serviceNow_updateTask

There is often a desire to update a change task based on certain fields in the task. For example, you could update all planning tasks to closed based on their type or update a single task that matches a specific field.

This function will run either a query or search for a ctask name, based on the fields set on the serviceNowItem parameter. If there is a ctask field set, then it will not add the query string, as a query is intended to be more broad that the ctask field.

Required Parameters

serviceNowItem

• sysId - SysId change to get CTask from

Optional Parameters

Must specify one of

serviceNowItem

• ctask - String description of the ctask for querying (optional)
• query - A more generic ServiceNow query to locate the task

Response

result - a list of ctask sys_ids that were updated

Example

Update all planning tasks to in progress state

serviceNow_updateTask serviceNowConfiguration: [instance: 'exampledev'],
  credentialsId: 'servicenow',
  serviceNowItem: [sysId: 'fd03ba34db4f9f40ec45b2bd2b96197d',
    query: 'change_task_type=planning',
    body: '{"state":"2"}'
  ]

serviceNow_attachFile

Required Parameters

serviceNowItem

• sysId - SysId to attach to (can be Change Request or CTask)
• body - String body of file to attach
• filename - Filename to upload into ServiceNow

def myFile = readFile file: 'my-test-file.txt'
serviceNow_attachFile serviceNowConfiguration: [instance: 'exampledev'], credentialsId: 'jenkins-vault', serviceNowItem: [sysId: 'agsdh0wehosid9723h30h', body: myFile, filename: 'my-test-file.txt'], vaultConfiguration: [url: 'https://vault.example.com:8200', path: 'secret/for/service_now/']
