# Nix application VMs: security through virtualization
|
|
|
|
Simple application VMs (hypervisor-based sandbox) based on Nix package manager.
|
|
|
|
Uses one **read-only** /nix directory for all appvms. So creating a new appvm (but not first) is just about one minute.
|
|
|
|
|
|
|
|
## Dependencies
|
|
|
|
$ sudo apt install golang virt-manager curl git
|
|
$ sudo usermod -a -G libvirt $USER
|
|
|
|
$ echo 'export GOPATH=$HOME/go' >> ~/.bash_profile
|
|
$ echo 'export PATH=$PATH:$GOPATH/bin' >> ~/.bash_profile
|
|
$ echo 'source ~/.bash_profile' >> ~/.bashrc
|
|
$ source ~/.bash_profile
|
|
|
|
You need to **relogin** if you install virt-manager (libvirt) first time.
|
|
|
|
## Install Nix package manager
|
|
|
|
$ sudo mkdir -m 0755 /nix && sudo chown $USER /nix
|
|
$ curl https://nixos.org/nix/install | sh
|
|
$ . ~/.nix-profile/etc/profile.d/nix.sh
|
|
|
|
## Libvirt from user (required if you need access to shared files)
|
|
|
|
$ echo user = "\"$USER\"" | sudo tee -a /etc/libvirt/qemu.conf
|
|
$ sudo systemctl restart libvirtd
|
|
|
|
## Install appvm tool
|
|
|
|
$ go get code.dumpstack.io/tools/appvm
|
|
|
|
## Update appvm tool
|
|
|
|
$ go get -u code.dumpstack.io/tools/appvm
|
|
|
|
## Search for applications
|
|
|
|
$ appvm search chromium
|
|
|
|
## Generate new application
|
|
|
|
$ nix-channel --list
|
|
nix https://nixos.org/channels/nixos-unstable
|
|
$ appvm generate nix.firefox
|
|
|
|
## Run application
|
|
|
|
$ appvm start chromium
|
|
$ # ... long wait for first time, because we need to collect a lot of packages
|
|
|
|
## Synchronize remote repos for applications
|
|
|
|
$ appvm sync
|
|
|
|
You can customize local settings in **~/.config/appvm/nix/local.nix**.
|
|
|
|
Default hotkey to release cursor: ctrl+alt.
|
|
|
|
## Shared directory
|
|
|
|
$ ls appvm/chromium
|
|
foo.tar.gz
|
|
bar.tar.gz
|
|
|
|
## Close VM
|
|
|
|
$ appvm stop chromium
|
|
|
|
## Automatic ballooning
|
|
|
|
Add this command:
|
|
|
|
$ appvm autoballoon
|
|
|
|
to crontab like that:
|
|
|
|
$ crontab -l
|
|
* * * * * /home/user/dev/go/bin/appvm autoballoon
|
