FAQs about using Vagrant for building and managing virtual machine environments
Vagrant is a tool for building and managing virtual machine environments in a single workflow. With an easy-to-use workflow and focus on automation, Vagrant lowers development environment setup time, increases production parity, and makes the “works on my machine” excuse a relic of the past.
First, edit Vagrant file to add external disk configuration.

Git Large File Storage (LFS) is an open source Git extension for versioning large files that replaces large files such as audio samples, videos, datasets, and graphics with text pointers inside Git, while storing the file contents on a remote server like GitLab, GitLab.com, GitHub.com or GitHub Enterprise.
After installing Lens manually (not using a package manager file such as .deb or .rpm) the following will need to be done to allow protocol handling. This assumes that your linux distribution uses xdg-open and the xdg-* suite of programs for determining which application can handle custom URIs.
Create a file called lens.desktop in either ~/.local/share/applications/ or /usr/share/applications (if you have permissions and are installing Lens for all users).
That file should have the following contents, with <path/to/executable> being the absolute path to where you have installed the unpacked Lens executable:
1 2 3 4 5 6 7 8 9 10
[Desktop Entry] Name=Lens Exec=<path/to/executable> %U Terminal=false Type=Application Icon=lens StartupWMClass=Lens Comment=Lens - The Kubernetes IDE MimeType=x-scheme-handler/lens; Categories=Network;
Then run the following command:
1
$ xdg-settings set default-url-scheme-handler lens lens.desktop
If that succeeds (exits with code 0) then your Lens install should be set up to handle lens:// URIs.
