I was recently ordered by our IT team to disable the NAT pools on my service fabric cluster due to security risks. The only way I could do this was to deploy a new cluster with all its components.
Because this is a test environment I opt to use a self signed cert without a password for my cluster, the certificate is in my vault and the cluster is up and running.
The issue I have now is when I try to deploy my application from an Azure Devops Release Pipeline I get the following message:
An error occurred attempting to import the certificate. Ensure that your service endpoint is configured properly with a correct certificate value and, if the certificate is password-protected, a valid password. Error message: Exception calling "Import" with "3" argument(s): "The specified network password is not correct.
I generated the self signed certificate in Key Vault, downloaded the certificate and used Powershell to get the Base64 string for the service connection.
Should I create the certificate myself, with a password?
With the direction of the two comments supplied, I ended up generating a certificate on my local machine using the powershell script included with service fabric's local run time.
A small caveat here is to change the key size in the script to a large key size than the default, because ke vault does not support 1024 keys.
I then exported the pfx from my user certificates added a password(this is required for the service connection) and impoted the new pfx into my key vault.
Redeployed my cluster and it worked.

I'm running into certificate errors when I run "puppet agent -t" using a vault lookup module in my branch for the agent config. Here's the errors I get:
"Failed to apply catalog: certificate verify failed" and "The certificate for does not match its private key"
The error persists even after I swap back to the production branch for the agent, where we then have to do an SSL clean to get the prod agent config to apply successfully.
Would setting up puppet to be the intermediaery CA be a good idea? Anybody run into this before?
We also setup approle auth for vault, but to no avail. Any help would be appreciated, thanks!
Unsuccessful solutions: vault app role auth, generating new keys, defining the ssl_cert manually in the agent config, and cleaning the agent cert from the master.
I am creating New Kubernetes service connection in Azure DevOps Server 2020 Update 1 via KubeConfig.
When I click to Verify that the connection it says that Verification Failed with the generic error:
Failed to query service connection API: 'https://ekm.mpu.cz/k8s/clusters/c-qmcrb/api/v1/nodes'. Error Message: 'An error occurred while sending the request.'
Please note that the Kubernetess instance is in the other domain.
I have the notion that the error could be with the certs are not imported somewhere on the machine, where the Azure DevOps is hosted, but I am unsure where. The MS documentation is silent about that as well.
So far I've tried to:
Import CA certs to the MMC under trusted publishers.
Import CA certs under cacerts in JAVA-HOME via keytool.
Import CA certs into azureTrustsStore.jks in JAVA-HOME via keytool.
For all 3 I've checked that the CA certs are imported correctly. But to no avail. Could you please advice or redirect me to the method, how to do it?
Additional Info:
While I cannot Verify and Save the connection, I still can Save it and then use it in the pipeline and it works OK! (sucesfully connect and execute the command).
Connection issues can occur for many reasons, but the root cause is often related to an error with one of these items: Network, Authentication, Authorization. You may refer to Basic troubleshooting of cluster connection issues for detailed troubleshooting steps.
i have an app (stateless) running as C# executable in my SF cluster. the App uses Managed identity to connect to Azure Key Vault. i have granted Key vault accss policy to the Virtual Machine Scale set managed identity, but when app tries to connect to Key vault, it gets exeption
" Azure.Identity.AuthenticationFailedException (-2146233088)
DefaultAzureCredential failed to retrieve a token from the included credentials.
EnvironmentCredential authentication unavailable. Environment variables are not fully configured?
Most of the articles talks about this exception when running on local machine. But i am running SF on azure, but still getting exception.
Any pointers on how to troubleshoot further.
I need some help with deploying a Service fabric app from Team Services to Azure.
I’m getting the following error from the Agent in Team Services (see screenshot below):
2018-06-22T13:17:13.3007613Z ##[error] An error occurred attempting to
import the certificate. Ensure that your service endpoint is
configured properly with a correct certificate value and, if the
certificate is password-protected, a valid password.
Error message: Exception calling "Import" with "3" argument(s):

Please advise.
Here is my Service Fabric Security security page, don't remember where I set up the password needed on the VSTS side but I took note of it and believe it's correct.
Here is the Endpoint page on the VSTS side:
Issue resolved with the help of MS Support by creating a new Certificate in the Key Vault and Adding it to the Service Fabric, steps:
Azure Portal:
Home > Key vaults > YourKeyVault - Certificates: Generate/Import
Generate new key with a CertificateName of your choosing and CN=CertificateName as Subject.
Home > Key vaults > YourKeyVault - Certificates > CertificateName
Select the only version available and Download in PFX/PEM format.
Power Shell: Convert to Base64 string, CertificateBase64
[System.Convert]::ToBase64String([System.IO.File]::ReadAllBytes("c:\YourCertificate.pfx"))
Home > YourServicefabric - Security: Add
Add the Certificate you created as Admin Client by providing 's thumbprint.
VSTS/TFS:
Build and release > Your pipeline: Edit
In the Deployment Process Service Fabric Environment click Manage for Cluster Connection and add a new connection. Besides the other information, in the Client Certificate paste the previous CertificateBase64.
Check the Service Endpoint in VSTS:
Whether it has a properly base64 encoded certificate, with a private key.
Also, check if the provided passphrase is correct.
Also, check if the service endpoint is configured as tcp://mycluster.region.cloudapp.azure.com:19000.
Check if the thumbprint is correct.
I want to secure my own HTTPS end point (node.js express.js server) with a certificate which I have deployed to the cluster (that is, it exists in Cert:\LocalMachine\My).
I of course want to avoid having my certificate in source control. I can't use an EndpointBindingPolicy in the ServiceManifest because as far as I'm aware that is just for http.sys(?) based systems, which this isn't.
What I thought is perhaps run a SetupEntryPoint script to:
grab the certificate from the store
export it as a pfx with a random passphrase (or some appropriate format)
copy it to {pkgroot}/certs/ssl_cert.pfx
replace some sort of token in serverinit.js with the random passphrase
This way the server, er, code base doesn't need to have the certificate present, i just needs to trust that it will be there when the service is run.
However I don't think I can do this, if it even is as sensible idea, as the certificates in the store are marked such that the private key is non-exportable! Or, at least, they are with my RDP account!
Is there a way to export the certificate with its private key?
What are my options here?
I ended up writing a powershell script which runs in my release pipeline, arguments are clientID, clientSecret and certificateName. clientSecret is stored as a protected environmental variable for my agent.
Create new application registration under same subscription as KeyVault (which should be same as SF Cluster) (e.g. in portal.azure.com)
Note down app ID
Create app secret
Modify KeyVault ACL with App as principal, set get only on secrets
use REST api with client ID and secret https://learn.microsoft.com/en-us/rest/api/keyvault/getsecret
I chose this over grabbing the certificate in the SetupEntryPoint, for example, as this hides the client secret better from the open world (e.g. developers who shouldn't/don't need access to it)
