I am running Windows 10 Enterprise (64-bit) in virtual environment.
I have installed Docker and VirtualBox in it.
For my work, I need a Windows container base image (with .NET support).
I tried getting one at https://hub.docker.com/_/microsoft-windows-base-os-images?tab=reviews
But, could not pull a Windows or Windows Server Core image.
Please let me know if you know how to get and use Windows container base image.
According to the documentation available on docker-hub:
Windows requires the host OS version to match the container OS
version. If you want to run a container based on a newer Windows
build, make sure you have an equivalent host build. Otherwise, you can
use Hyper-V isolation to run older containers on new host builds.
You are probably trying to pull a non-compliant image. Check your windows version and accordingly select the proper tag to pull.

I'm trying to profile a Java app running with AdoptOpenJDK 11 version OpenJ9.
My problem is that, when I try to attach JProfiler on my app, it doesn't detect the running instance.
I'm using the last version of JProfiler (11.1.4).
Is it compatible with this JRE?
Is there something to do/configure to make it working?
Best regards
As of JProfiler 11.0, attach mode is not supported for OpenJ9 JVMs. Also, attach mode is not enabled by default for OpenJ9.
When passing the -agentpath VM parameter as given by the integration wizards, profiling OpenJ9 JVMs is fully supported.
I'm currently trying to connect MongoDB to a Windows QT C++ application and am following the tutorial here. While there Windows installation instructions are presented, to avoid having to install Visual Studio or other tools, I'm wondering if I can follow the package-manager or Linux instructions on the inbuilt Linux/ Ubuntu subsystem of Windows 10 and build the libraries in my Linux environment, later somehow accessing them from my Windows development environment.
I don't fully understand how compilation/ byte-code works in the Linux subsystem on Windows, so I haven't been able to piece together an answer for this myself based on my understanding of the various systems involved. Any explanation or assistance would be appreciated.
You can run a Windows executable from a WSL console window or a Linux executable from Windows command line / power shell. And capture the output, pipe between applications etc. But the application must run entirely on one platform; you cannot mix a Windows executable with Linux libraries or vice-versa.
I don't know how you will connect to MongoDB but, if it has a socket interface like MySql, you could create a bash script on WSL which runs your QT application to access the database, wherever it is.
But if you're using QT as a GUI you're going to struggle. People have been able to get a Linux desktop running on WSL by installing an X server on the Windows host but you might find that more trouble than it's worth.
I've got a question about VMs and installing programs.
I've got a vsphere 6.0 running on my server and I try to automatically create new VMs (or use clean installed snapshots) an then automatically install software on these VMs.
e.g.:
A user wishes to create a new Windows 7 with xampp installed and firefox + thunderbird + eclipse. The VM will be created and during the first start these programs will be installed.
Is this possible or are there any tools that can help?
Or can I use the VMware API to realize this?
Thank you very much.
There is no way that Vsphere can do these installations that I know of. In fact I don't know of a way to install an application to a running windows box remotely - you can imagine the security implications of that.
There is an easy way to do this however.
I would build my windows VM, install all the required applications (leaving them as configured or not depending on your needs) then convert the VM into a template and then deploy new vms based on that template. Then you have your windows vms ready to go with the installed applications.
I am beginning to set up on Restcomm Mobicents framework.
In particular I am trying to set up Restcomm on my Windows 8.1 laptop.
Can anyone assist with how to set up RESTCOMM on Windows Server please. The reason I ask this is that most of the information is presumed to be on Linux, Ubuntu. Environments like "installation of screen" and also any sample configuration shared are for Ubuntu, Linux environments, but not specifically on Windows.
Restcomm is currently prepared to run natively on Linux operating systems, indeed.
Considering the diversity of OSs and configurations, a Docker image was created to gather everything Restcomm needs to run properly, as an independent layer.
Please check the following links to install Docker in Windows 8.1 and use Restcomm docker image.
About docker: https://www.docker.com/what-docker
Docker installation: http://docs.docker.com/windows/step_one/
About Restcomm docker image: http://www.telestax.com/docker-image-for-mobicents-restcomm-7-3-0/
Restcomm docker image: https://hub.docker.com/r/gvagenas/restcomm/
You should avoid installing Restcomm on windows, although the simulation will work, when you will have to go live, you will be unable because Windows does not implements the SCTP stack need by Restcomm.
Is is possible to automate the installation of an OS using VMware or any other virtualization product?
One of our products consists of a customized version of CentOS that installs the OS and our application on a server. It's much like any CentOS/RHEL installation where you choose a mode that corresponds to different kickstart options, and then you choose your keyboard type. The rest of the installation is automatic.
What I'd like to have is an automated system that will create a new guest VM, boot it with the ISO image of our product, start the installation (including choosing the keyboard), wait for the reboot, and then launch a set of automated tests.
I know that there are plenty of ways to automate the creation of new VM guests from existing templates/images, and I know you can use the VIX API to interact with virtual machines, but the VIX API seems to require that VMware tools is already running (which won't be the case when you're booting from the CentOS install disk).
This answer (Automating VMWare or VirtualPC) indicates that you can script VMware to boot from an ISO that does an unattended installation, but I would really like to test the same process that our customers will be using.
Another option might be to use Xen's fully-virtualized mode and see if scripting it over the serial port will work.
TIA,
Jason
I have a very very similar question, it is on superuser:
https://superuser.com/questions/36047/moving-vmware-os-image-as-primary-os-on-a-system
You can also use VirtualBox instead of VMWare. The VirtualBox SDK allows you to directly control the keyboard, the mouse the serial port and the parallel port of the guest without the virtualbox guest tools installed.
Unfortunately it doesn't offer a text console interface but the serial port can be connected to a local pipe file and that can probably be worked with just as well.
This may not be exactly what you need:
I have done something similar with a Ubuntu-based install. We used preseeding (Debian's form of kickstart), to answer all the questions during the install - providing the preseed file and the installer via tftp.
In addition to the official Ubuntu mirror we added the apt-server with our own packages in the preseed file. We put a .deb version of vmware-tools on the apt-server and added it to the packages to be installed.
The .deb of vmware tools just contained the .tar.gz and a postinstall script that would extract it to /tmp and run the vmware install script (which has a switch to be run unnattended, so it does not ask any questions).
So after the reboot vmware-tools were up and running and we could use vix to script the rest (which was not very reliable).
If you should encounter problems with running vmware-config.pl during boot, you could make a custom package that just extracts the tools and an init script that installs them on first boot, disables itself and reboots.
Maybe you can use this strategy (replacing apt by yum, preseed by kickstart and tftp by a remastered iso). If you really need to test that your users choose a keyboard in the installer (which is not very different from kickstart) this would obviously not work for you..
