Lack of Swap Space in Azure Linux VM

Lack of Swap Space in Azure Linux VM

I’ve recently started using the CentOS Linux VM’s in Azure for some work that requires Linux. One thing I noticed quickly after starting to use them was that these VM’s do not come with any swap space configured by default. You can go ahead and create a swap partition using the standard methods, but when you reboot the VM it won’t perisist, which was a bit infuriating. That was until I discovered that you can make this change in the Azure Linux agent that is installed by default on each VM and it will take care of it for you.
