I need to install software on Azure VM with Ubuntu image. One way of manually doing it is ssh into the terminal using putty or other command-line tool and executing the installation bash command. Another way of doing it was by automating this by creating a bash script and calling it from Azure automation. But I unable to find a way to call the bash script from the azure automation runbooks. Kindly let me know if this is possible.
I am able to call powershell scripts because Azure Automation supports powershell by default.
I tried using the command New-SshSession and using Invoke-SshCommand to run my command but I get the below error while trying to connect to a session.
Also, what are the prerequisites for using New-SshSession (see below)?
New-SshSession -ComputerName 'ComputerName' -Username 'UserName'
Unable to create SSH client object: Exception calling ".ctor" with "4" argument(s): "Could not load type 'System.Security.Cryptography.HMACRIPEMD160' from assembly 'mscorlib, Version=4.0.0.0, Culture=neutral,
Are there any prerequisites before I should start using New-SshSession? Do I need to install any .Net library on my linux machine?
Welcome to Stack Overflow!!
If the requirement was for Windows VM then it would have been easy by leveraging Invoke-AzVmRunCommand cmdlet but as requirement is for Linux VM so looks like the comment (with sample script) provided by Azure Automation team content author in this GitHub helps you to accomplish your requirement of executing bash commands on Azure Linux VM using azure automation.
Hope this helps!!

Recently, I tried to create self-signed certificate for Azure Service Factory accordingly with Microsoft's manual:
Azure Docs: Secure a Service Fabric cluster, step 2.5, 02/05/2016
But command Invoke-AddCertToKeyVault failed with the next error:
Invoke-AddCertToKeyVault : The term 'Invoke-AddCertToKeyVault' is not
recognized as the name of a cmdlet, function, script file, or operable
program. Check the spelling of the name, or if a path was included,
verify that the path is correct and try again.
I think that Azure Powershell successfully installed on my machine because I was able to login into my Azure account by running Login-AzureRmAccount. Also $env:PSModulePath says that Azure Modules path added to path variable (accordingly with the article: Azure Docs: How to install and configure Azure PowerShell, 04/22/2016). Here they are:
...\Microsoft SDKs\Azure\PowerShell\ResourceManager\AzureResourceManager\;
...\Microsoft SDKs\Azure\PowerShell\ServiceManagement\;
...\Microsoft SDKs\Azure\PowerShell\Storage\;
Also, I have restarted my PC after installing Azure PowerShell.
It is possible that I have missed something, but I am stuck with it. How could it be resolved?
That commandlet is in the package that should be imported -
Import-Module "C:\Users\chackdan\Documents\GitHub\Service-Fabric\Scripts\ServiceFabricRPHelpers\ServiceFabricRPHelpers.psm1"
That is its implementation, by the way, for a reference that it even exists :). Try Import-Module and it should work.
I am creating Windows VMs from the azure xplat cli, using the following command:
azure network vnet create --location "East US" testnet
azure vm create --vm-name xplattest3 --location "East US" --virtual-network-name testnet --rdp 3389 xplattest3 ad072bd3082149369c449ba5832401ae__Windows-Server-Remote-Desktop-Session-Host-on-Windows-Server-2012-R2-20150828-0350 username SAFEpassword!
After the Windows VM is created I would like to execute a powershell script to configure the server. As far I understand, this is done by executing a CustomScriptExtension.
I found several examples for PowerShell but no examples for Xplat cli.
I would like, for example, to run the following HelloWorld PowerShell script:
New-Item -ItemType directory -Path C:\HelloWorld
After reading documentation I should be able to run a CustomExtensionScript by executing something like this (the following command does not work):
azure vm extension set xplattest3 CustomScriptExtension Microsoft.Compute 1.4 -i '{"URI":["https://gist.githubusercontent.com/tk421/8b7dd37145eaa8f82e2f/raw/36c11aafd3f5d6b4af97aab9ef5303d80e8ab29b/azureCustomScriptExtensionTest"] }'
I think that the problem is the parameter -i. I have not been able to find an example on Internet. There are some references and documentation such as MSDN and Github, but no examples.
Therefore, my question: How to execute a PowerShell script after creating a Windows VM in Azure using the xplat cli ?
Please note that the my current approach is a CustomScriptExtension, but anything that allows to bootstrap a configuration script will be considered!
EDIT How do I know it is failing ?
After I run the command azure vm extension ...:
xplat cli confirms that the command has been executed properly.
As per MSDN documentation, the folder C:\Packages\Plugins\Microsoft.Compute.CustomScriptExtension\ is created, but there is no script downloaded to C:\Packages\Plugins\Microsoft.Compute.CustomScriptExtension\{version-number}\Downloads\{iteration}
The folder C:\HelloWorld is not created, which means that the contents of the script has not been executed.
I cannot find any sort of logs or a trace to know what happened. Does anyone knows where can I find this information ?
The parameters (The Json) that I used after reading the MSDN documentation were not correct. However, you can get clues of the correct parameters by reading the C# code.
And the final command is:
azure vm extension set xplattest3 CustomScriptExtension Microsoft.Compute 1.4 -i '{"fileUris":["https://macstoragetest.blob.core.windows.net/testcontainername/createFolder.ps1"], "commandToExecute": "powershell -ExecutionPolicy Unrestricted -file createFolder.ps1" }'
This command successfully creates the C:\HelloWorld directory.
NOTE: I decided to upload the script to Azure as I read in a post and in the documentation that is mandatory. However I just made a test to download the original script from Github and it is working fine, so I guess that the documentation is a bit outdated.
EDIT: I created an detailed article that explains how to provision windows servers with xplat-cli in Azure.
I just installed nodejs on one of my build servers (Win Server 2008 R2) which hosts a Bamboo remote agent. After completing the installation and doing a reboot I got stuck in the following situation:
The remote Bamboo build agent is running as a windows service with user MyDomain\MyUser. When a build with an inline powershell task is executing it fails with the error (from the build agent log):
com.atlassian.utils.process.ProcessNotStartedException: powershell could not be started
...
java.io.IOException: Cannot run program "powershell"
...
java.io.IOException: CreateProcess error=2, The system cannot find the file specified
Loggin on to the server as MyDomain\MyUser, I have checked that powershell is in the path:
where powershell
C:\Windows\System32\WindowsPowerShell\v1.0\powershell.exe
I have tried to restart the service and reboot the machine multiple times. No luck. The only thing that works is if I execute my scripts as a bat file with an absolute path to powershell - but I do not want that.
I have searched for solutions on this, but even though this one seems related: Hudson cannot find powershell after update to powershell 3 - the proposed solutions do not work.
What am I missing here?
If you do a default installation of nodejs you will see that it adds nodejs and npm to the path. Sometimes I have seen that the installer adds a user variable named PATH - it might be that the Bamboo agent decides to read the user path without "merging" it with the system path. I think it would be worth a try to give that a look.
As per Atlassian support page, this is related to a bug in Java Service Wrapper. I tried Workaround-2 since there was no user PATH variable in my system. I had to uninstall bamboo agent service and Java 64 versions from the agent machine to apply the workaround-2.
I've got a continuous integration server (Jenkins ) which builds my code (checks for compilation errors) and runs tests and then deploys the files to a remote server (not a war file, but the actual file structure) I do this with a Jenkins plugin which allows me to transfer files via samba, it does this nightly.
Now, what I need to do is run an ant command on the remote server. And after that I need to start the application server on the remote server, the application server is started by running a .bat file from the command line.
I'm pretty clueless how to accomplish this, I know Jenkins is capable of running batch commands, but how do I make them run in the context of the server and not the context of the build server?
If Jenkins on Windows, remote on *nix, use plink.exe (which is essentially command line PuTTy)
If Jenkins on Windows, remote on Window, use psexec.exe
If Jenkins on *nix, remote on *nix, use ssh
If Jenkins on *nix, remote on Windows, (update 2015-01) Ansible http://docs.ansible.com/intro_windows.html has support for calling Windows commands, eg powershell, from a unix/linux machine, https://github.com/ansible/ansible-examples/blob/master/windows/run-powershell.yml
Tell me what OSes are involved (both on Jenkins and remote), and I will flash this out further.
Edit:
The download page for psexec.exe lists all command line options. You will want something along the lines of:
psexec \\remotecomputername -u remoteusername -p remotepassword cmd /c <your commands here>
Replace <your commands here> with actual commands as you would execute them from command prompt.
Note that psexec first needs to install a service, and required elevated command prompt/admin remote credentials to do so.
Also, you need to run psexec -accepteula once to accept the EULA prompt.
Following Slav's answer above, here is a simpler solution for Jenkins (*nix) to remote (windows):
Install an SSH server on your remote windows (MobaSSH home edition worked well for me)
Make sure your Jenkins user, on your Jenkins machine, has the required certification to open an SSH connection with your remote (you can simply open a terminal and ssh to your remote once, then accept the certification. Make sure it is saved for the Jenkins user).
You can now add an execute shell build phase in your Jenkins job which can SSH to your remote windows machine.
Notes :
The established connection might require some additional work - you might have to set windows environment variables or map network drivers in order for your executed commands or batch files to work properly on your windows machines.
If you wish to run GUI related operations this solution might not be relevant (Following my work on running automation tests which require GUI manipulation).
Using Jenkins SSH plugin is an issue, as seen here.
1、i install (MobaSSH home ) on my remote windows server .
2、and install jenkins ssh plugin
3、edit shell eg: go build project
4、it seems something wrong ,
" go: creating work dir: CreateFile C:\WINDOWS\system32\bsh\tmp: The system cannot find the path specified."
I ended up going with a different approach after trying out psexec.exe for a while.
Psexec.exe and copying files over the network was a bit slow and unstable, especially since the domain I work on has a policy of changing password every months (which broke the build).
In the end I went with the master/slave approach, which is faster and more stable. Since I don't have to use psexec.exe and don't have to copy files over the network.
I am trying to execute a program inside of a power shell script. The PS script is being called from a C# method using Runspaces. The program tries to make an update to a config file on a remote server. When I run this whole thing I get the following error:
System.UnauthorizedAccessException: Access to the path \\some path is denied.
The PS script is on a remote server. If I run the PS script directly on the server then the PS script and the program inside of it runs fine and is able to access the remote system.
Has anyone run into this before? I was told that this is failing because I am running it through Visual Studio and C# and that I won't be allowed to access network resources through a powershell script that is being run through a C# class. Someone else told me that the permissions that I am using to start the PS script in the runspace are not translating to the program that I am calling within the script.
Other ideas and possible solutions?
Thanks
It looks like you're trying to modify a file on a UNC path on a secondary server. This won't work due to the age old "double hop" problem. You are on machine A, executing a remote script on B that tries to modify a file on C. Your authentication from A to B cannot be reused to connect from B to C. This is a design limitation for NTLM (windows integrated authentication.)
However, all is not lost: You must use CredSSP authentication when connecting with powershell remoting from A to B, and then you can connect to C without a problem.
