A minimal Galaxy for Cosmos used to demonstrate local and offline installation flows.

This repository contains a basic working Galaxy with a small, statically linked hello binary and a sample Nebula (core-stack) to show how a Cosmos install flow works.

• hello – statically linked binary, installs to /usr/bin/hello
• core-stack – a Nebula that depends on hello, simulates a base install stack

1. Add this Galaxy to your config.toml:

[galaxies]
example = "file:///path/to/example-galaxy"

2. Run a test install:

cosmos install core-stack --root ./test-root

3. Inspect:

ls ./test-root/usr/bin
./test-root/usr/bin/hello

Run it if you’re brave:

chroot ./test-root /usr/bin/hello

• A working example of a local/offline Cosmos Galaxy
• A reference for Galaxy structure and metadata layout
• A testable install target for Stellar-built packages

• Secure
• Signed
• Maintained for long-term use
• A full Linux base system (see LFS Galaxy)

To build a new package:

stellar new-star mypkg
# edit star.toml and files/
stellar build-star ./mypkg
# move the .tar.gz to packages/ and star.toml to stars/

Then update meta.toml to include the new Star and version.

• Cosmos CLI & Core
• Stellar Package Builder
• Documentation

If you can install this, you can install the world.
