SSH agent forwarding for devcontainer builds - vscode-devcontainer

is there a way to use SSH agent forwarding during build in devcontainer.json?
For SSH agent forwarding I mean --ssh flag during build and devcontainer being a part of Visual Studio code

running SSH script command from jenkins using SSH

To deploy application on linux ubuntu server I have bunch of SSH commands that i currently run using PuTTY. The server has local account serviceaccount1. In PuTTY i connect to server using serviceaccount1 and executes the following commands one by one
cd /home/serviceaccount1/cr-ml
script /dev/null
screen -S data_and_status
cd cr-ml/notebooks
source activate crml
unset XDG_RUNTIME_DIR
jupyter kernelgateway --api='kernel_gateway.notebook_http' --seed_uri='data_and_status_api.ipynb' --port 8894 --ip 0.0.0.0
...
...
and so on
Now i want automate this using Jenkins. I installed SSH plugin, configured credential using SSH Username serviceaccount1 with private key
Then created a new jenkins project and added a build step Execute shell scripts on remote host using ssh and then add all the above commands.
When i build the jenkins project, it get stuck at executing 2nd command script /dev/null
i see the following console output
To me, it seems the culprit is the screen -S data_and_status command. Once you start a screen, I don't think you would be able to execute the subsequent commands over the SSH connection.
Alternatively, you can try using a tool like Ansible to run a bunch of commands against a remote server.

GitLab CI/CD pipeline, deploy to Windows Server

Using GitLab Runner I have on Linux, I am trying to connect to a Windows Server and run some basic commands there such as git pull.
Does GitLab runner provide any capabilities for accessing windows server?
What other options are there to get such requirement done?
I think you have a few options
install openssh and configure server on your windows machine/vm and connect from your gitlab runner with ssh ( https://learn.microsoft.com/en-us/windows-server/administration/openssh/openssh_install_firstuse )
( as Wojciech Wirzbicki commented) install a gitlab runner instance on windows. https://docs.gitlab.com/runner/install/windows.html . I think this option more secure and easy win
connect to windows server with winrm

Can't connect to "Jenkins-On-Azure"

I created a Jenkins linux vm on Azure on a new resource group.
I followed the steps described here:
Create a Jenkins server on an Azure Linux VM from the Azure portal.
So I ran the command ssh -L 127.0.0.1:8080:localhost:8080 jenkinsadmin#jenkins2517454.eastus.cloudapp.azure.com
(changed the username and dns name to my own) on my linux vm and it seems fine (no errors).
Now whenever I try to connect from my own computer (not on azure) on port 8080 I get on the linux vm the following message: channel 2: open failed: administratively prohibited: open failed and It doesn't let me log in into Jenkins.
How can it be solved?
Thank you
This is not a NSG issue. You don't need add port 8080 on Azure NSG rules.
If you want to connect from your computer with http://localhost:8080/, you should need create a SSH tunnel on your local computer. You could do it with putty.
Configure the Tunnel
Also, you could install Linux on Windows. Please refer to the following steps:
1.Install Linux on Windows.
2.Open Power shell on execute bash
3.Execute sudo -i and ssh -L 127.0.0.1:8080:localhost:8080 jenkinsadmin#jenkins2517454.eastus.cloudapp.azure.com
Now, I could access http://localhost:8080/ on my local computer.(The default user name is admin).
In order to access from external network, you need to "add inbound port rule" as follows:

Grails run-app fails on VM VirtualBox: hangs on build, can't access server

I'm new to Grails and attempting to implement the Hello World app described at grails.org's Getting Started guide.
I have installed Grails using SDKman on an Ubuntu Server 16.04 VM (VirtualBox, running as a service). My host machine is Windows 10.
I configured two network adapters in VirtualBox: the first a NAT with port forwarding (3022 host -> 22 guest, 8080 host -> 8080 guest), the second a Host-Only adapter.
I can SSH into my VM just fine from my Windows host (using Bash): ssh -p 3022 user#localhost
When I run python3 -m http.server 8080 from that SSH session, it successfully listens on both localhost:8080 and :8080. I can access both URLs from a browser on my host machine.
When I run grails run-app it hangs forever, and none of the above endpoints work from my host.
When I run grails run-app --verbose I see it compile without complaint through "Building 85% > :bootRun". I understand that this is expected behavior, but I never see "Application started" or any similar message. It never starts.
ONE TIME the following command succeeded in building and running the app, creating exactly the result I needed:
grails -Dserver.port=8080 -Dserver.host=0.0.0.0 run-app --verbose --stacktrace
However when I stopped the app and tried again, it failed as before.
I notice that VirtualBox > Settings > Network > Adapter #2 which I had set as "Host-Only Network" has multiple times reset itself to Bridged. I suspect that this reset may have caused my problem. But I don't know how to prevent the reset, or to restore that functionality I so briefly had.
Thanks, anyone who can help!
Resolved! Turns out run-app just takes a LONG time to finish compiling and building, upwards of 10 minutes. So I just needed to wait ~5+ minutes with no visual sign of action before the completion message would show and I could access my site. :)

cygwin/sshd and Virtualbox

I'm using vagrant/VirtualBox on my Window (8.1) Laptop to start up a linux-test-vm from a Cygwin terminal... vagrant up, vagrant ssh, everything is working fine.
Now I want to work on that environment remotely from my main Linux-Workstation, so I've set up sshd in Cygwin and I can successfully ssh into my Windows-Box (same user as logged in locally in windows).
But when I cd'ed (via my remote ssh connection to windows-laptop) in my working directory and ran vagrant ssh, it tells me:
VM must be created before running this command. Run 'vagrant up' first
But I see the VM is running in VirtualBox GUI on Windows.
From this point on even locally on the Windows machine I can no longer interact with the running vagrant vm and the .vagrant (sub)directory has not files inside.
Same happens vice versa:
I stopped/deleted the VM in VirtualBox GUI
ran vagrant up via my ssh connection ... worked
ran vagrant ssh via my ssh connection ... works
but I do not see the VM in VirtualBox GUI on Windows
trying vagrant ssh locally on Windows ... same error again and .vagrant directory gets cleared
So I assume the Cygwin/sshd connection creates some sort of different Sessions that do not share the same "instance" of VirtualBox.
Is there any chance to share VirtualBox/vagrant environment between the local Windows and remote ssh session ???
WORKAROUND:
export ssh-config on the windows host: vagrant ssh-config > ssh_config
from the cygwin/ssh jump into the VM: ssh -F ssh_config default
never run any vagrant command from the cygwin/ssh connection
Vagrant has a built-in solution since the 1.7.x versions called vagrant share which also allows you to remote into a box directly (bypassing the Windows host abstraction). It is generally used for the HTTP feature (eg. to show clients or others on a project the current state of work) but there is the ability to connect to any service running on any port. From the docs:
Just call vagrant share. This will automatically share as many ports
as possible for remote connections. If the Vagrant environment has a
static IP or DNS address, then every port will be available.
Otherwise, Vagrant will only expose forwarded ports on the machine.
Note the share name at the end of calling vagrant share, and give this
to the person who wants to connect to your machine. They simply have
to call vagrant connect NAME. This will give them a static IP they can
use to access your Vagrant environment.
Note to use vagrant share you need a (free) account with hashicorp.
