[jithendra415]

We are facing problem in installing ALOps pipelines in new customer environments. since few days.

Error:

What we have done:

1. Install BC20 CU5
2. add new instances (OTAP)
3. add new Pipeline instances
4. configure Pipeline instances in BC administration panel
5. link instance to database
6. start the instances
7. Run script (which will be attached)
8. Error comes up at step 7 of the script.

Script:
##1, Import NAV/BC Module
Import-Module 'C:\Program Files\Microsoft Dynamics 365 Business Central\170\Service\NavAdminTool.ps1' ## Change to correct folder
##2, Set variables.
##Change to desired target instance and extension.
$PipelineInstance = 'BC170_PROD_Pipeline'
$Extension = 'Exclude_APIV1'
$DefaultInstance = 'BC170_PROD'
##2.5, Disable Design button to prevent Pipeline errors with conflicting extensions (deze stap zet Task Scheduler uit op de instance)
Set-NAVWebServerInstanceConfiguration -WebServerInstance $DefaultInstance -KeyName Designer -KeyValue false
##3, Check Extensions (APIV1)
##If installed go to step 6!!
Get-NAVAppInfo -ServerInstance $PipelineInstance -Name $Extension | Out-GridView
##4, Publish Extension
##File is in installation file (...\Applications\APIV1\Source\Microsoft__Exclude_APIV1_.app)
Publish-NAVApp -ServerInstance $PipelineInstance -Path '<PATH TO .APP FILE HERE>'
##5, Install App
Install-NAVApp -ServerInstance $PipelineInstance -Name $Extension
##6, Install & Import ExternalDeployer Module (ONLY HAS TO BE EXECUTED ONCE!!)
##If already installed, go to step 8!!
Install-Module ALOps.ExternalDeployer -Force
Import-Module ALOps.ExternalDeployer
##7, Install ALOpst External Deployer (ONLY HAS TO BE EXECUTED ONCE!!)
Install-ALOpsExternalDeployer
##8, Create new deployer
New-ALOpsExternalDeployer -ServerInstance $PipelineInstance
##9, Restart NST.
restart-NAVServerInstance -ServerInstance $PipelineInstance

The reason, why we have experienced, is that the powershell module has been changed. New parameters were added in order to give the possibility to work with multiple business central version on one server. Unfortunately, we were not aware of those changes and that background. Nowadays every serverinstance needs to the linked to own AlOps services (with it own portnumber).
