Jacob,


There are three pretty straight forward ways of doing this.  As Chris said, vagrant is a great tool.  You can use HyperV or VirtualBox pretty easily via vagrant.  HyperV is the virtualization technology/engine that vagrant uses to configure and run the VM.  An alternative option for simply getting experience with Linux is docker.  You can install docker and get a Linux container up and running really easily.  The last option is setting up a VM via WSL2.  Again, this is farily easily done.


do you know which Linux distribution your work is going to use for development and for production?  Which technology you use may be somewhat influenced by what target distribution you want to run in your VM.


PuTTY is pretty accessible and easy to use.  personally, I use PuTTY, but I also use the port of bash for MSys2.  Many of the Linux VMs you can get already have a SSH server set up.


Regards,


jad Wauthier

Thanks, I’ll definitely check that out. That would probably be helpful for 
local development. I suspect I may still have a need at some point to access 
some of these pre-existing Hyper-V VMs, so I imagine in that case I’d probably 
just need to get someone to configure it to have a working SSH server.

Jacob,

I've used Vagrant (www.vagrantup.com) for quickly getting virtual
machines up and running.

The Vagrant VMs are meant for development and testing, not production.

The steps would be:

1. make a new directory and cd to it

2. run 'vagrant init' which will create a file called Vagrantfile

3. Edit Vagrantfile to specify the setup of your VM (Linux distribution,
type of networking, etc.).

4. Run 'vagrant up' to create the VM

5. Run 'vagrant ssh' to connect via ssh using command-line, or 'vagrant
ssh-config' to print the ssh configuration that you'd need when setting
up a connection in a GUI client.

Hope this helps.

Chris

In an effort to modernize our software, we are moving away from monolithic 
applications that run on JBOSS. We are starting to containerize our 
applications, which means I will need to start getting educated about Linux 
since I really haven???t used it much at all. I use a screen reader, and I???m 
trying to anticipate any potential accessibility roadblocks now so I can 
hopefully focus on the other aspects of the learning curve without spending a 
bunch of time fighting with screen reading challenges.

I???m wondering if anyone has experience accessing a Linux virtual machine on 
Windows using Hyper-V. I believe I may need to do that in order to manage Linux 
containers, but I???m not sure the best way to make it accessible. It would be 
nice if I could access the VM from a terminal using my Windows screen reader, 
possibly by using Putty or something similar. I suspect the VM would need to be 
configured for that, so I???d probably need sighted help in order to set it up 
each time. If anyone has any suggestions for quickly getting screen reader 
access to a Linux virtual machine I would appreciate it very much.

Thanks!
