Bravetools

Bravetools provides a simple and consistent interface to declare, build, and deploy system containers.

Features

Build, version control, and share reproducible application and environment images.
Compose multi-container systems in a simple and declarative way.
Deploy your systems locally or remotely.

How it works

Configuring image environments

The steps to build and deploy an image are configured using a Bravefile.
View sample Bravefiles on GitHub to explore common use cases.

template

Build images

Build new images or layer existing ones using brave build
Resulting image can be stored locally or remotely

Deploy images

System containers can be deployed to a variety of environments with brave deploy, including local development machines, test environments, and remote production systems.

Image management

Manage images with multiple versions and architectures

Deploy multi-unit systems

Systems with multiple units can be declared in a brave compose file.
Build and deploy the system defined in a compose file with the brave compose command.

Installation

Prerequisites:

Mac/Windows: Multipass
Linux:
- LXD
- Ensure your user belongs to the lxd group: sudo usermod --append --groups lxd $USER
- You may also need zfsutils: sudo apt install zfsutils-linux

Installing from source

Linux/MacOS

git clone https://github.com/bravetools/bravetools
cd bravetools
make [ubuntu]/[darwin]

Windows

git clone https://github.com/bravetools/bravetools
cd bravetools
go build -ldflags="-s -w" -o brave.exe -trimpath main.go

Getting Started

Run brave init to start if you haven’t yet.

brave init

Create an example Bravefile

brave template

This creates a file named “Bravefile” in the current working directory. The contents should look like this:

image: example-image/v1.0
base:
  image: alpine/3.16
packages:
  manager: apk
  system:
    - curl
run: 
  - command: echo
    args:
      - hello world
copy:
  - source: ./Bravefile
    target: /root/
service:
  name: example-container
  ports:
    - 8888:8888
  resources:
    ram: 2GB
    cpu: 2
    disk: 10GB

Create an image using the Bravefile

brave build
...

Check images

brave images
IMAGE           VERSION ARCH    CREATED         SIZE    HASH
example-image   v1.0    x86_64  just now        4MB     ef28b49bf36f0b4b9cbad89ff67ef0ee

Deploy image as container

brave deploy

Check running units

brave units
NAME                    STATUS  IPV4            MOUNTS  PORTS     
example-container       Running 10.148.59.45            8888:8888

Add a remote

brave remote add example-remote https://20.0.0.20:8443 --password [PASSWORD]
Certificate fingerprint:  ...

Deploy to remote

brave deploy --name example-remote:example-container

brave units
NAME                                    STATUS  IPV4            MOUNTS  PORTS
example-remote:example-container        Running 20.0.0.7                8888:8888
