[Astlinux-devel] A quick and easy build environment

[David K. <da...@ke...>]

Devs,
  I just discovered multipass... https://multipass.run and decided to give
it a try.  It supports Mac, Windows (Pro, not Home) or Linux... for me I
installed it on Mac.  Once installed a one-line command gets you a running
Ubuntu 18.04 LTS environment...

multipass launch --name astbuild --cpus 2 --mem 1G --disk 10G

The first time you do that it takes a little time as it has to download the
Ubuntu image.  But once started you can

multipass shell astbuild

and then follow the instructions at
https://doc.astlinux-project.org/devdoc:documentation.

You can speed things up by creating a cloud-init file to install all our
required packages up-front, so for example on the above launch command
add...

 --cloud-init astlinux-cloud-config.yaml

where the contents of the yaml file is...
https://raw.githubusercontent.com/dkerr64/astlinux/develop/astlinux-cloud-config.yaml
so the first time you connect to the shell everything is ready for you to
git checkout the source, build and install Crosstool-NG and then build
AstLinux.

To get the built AstLinux image out of the VM you would want to

multipass mount <host-path> astbuild:<image-path>

so you can copy files in/out of the Ubuntu VM.

Enjoy,
David.
