As we focus more on our brownfield resources, one common requirement is to be able to execute scripts on brownfield VMs(Servers not provisioned through ServicveNow). As far as Greenfield Servers are concerned(VMs provisioned by ServiceNow), we already know about the credentials associated with VM, However, in case of brownfield VM's as Cloud discovery don't give back enough info to run scripts, so there is a manual process involved. Here are the steps which you can follow.
Prerequisite: Any vm on which you need execute script operation, you should know in advance what is the user name/password set , if the VM is accessible through private key, you will need to have that private key available physically.
Step1: Create a new SSH Key Pair type of credential with username/password/private key.
Step2: Associate these credentials with the VM, Go to sn_cmp_vm_node_user_creds,Set Orchestration Credentials as newly created SSH key pair credential. Set node against which these credentials were created.
Step3: Import the update set from share. click here
Step4: Make sure your Virtual Server is assigned to a group so that it shows up on portal. Set the Assign to field if not set already.
Go to Operation > Input Parameters,
1.Add a new parameter as resourceId with mapping as ${parameter.resourceId}
2. Change the expression for NodeAddress as $(Script:CMPVMUtils.getReachableIp[arg=${parameter.resourceId}])
3. Change the expression for NodeCredential as $(Script:CMPBrownfieldHelper.getNodeCredential[arg=${parameter.resourceId},arg=${parameter.CredentialId}])
4. you can alternatively ask the user credentials at runtime too, if that is the use case, you can create another Input parameter as CredentialId with mapping as ${parameter.CredentialId} (Not mandatory right now)
5.Make sure your operation type is public so that it shows up on portal as day2.
6. Cloud Scripts :You should have a valid Cloud Script and template setup in CMP which you can select from portal.
And you are done. Go to Cloud Portal >> Resources, Find your virtual server,
If you need to pass script parameters, you can make use of Resource Policies to pass additional script parameters.
