After construction on Travis, the installer is tested against a range of distribution that match the installer architecture ($ARCH). For example when architecture is aarch64, the constructed installer is tested against:

Centos 7
Debian Buster (10)
Ubuntu 16.04
Ubuntu 18.04
Ubuntu 19.10

Usage

Installers are built and uploaded via Travis but if you want to construct your own Miniforge installer, here is how:

# Configuration
export ARCH=aarch64
export DOCKERIMAGE=condaforge/linux-anvil-aarch64

bash build_miniforge.sh
