Assemble the SeedSigner OS along with the SeedSigner application code into an image file that can be flashed to an SD card and run in your SeedSigner.
macOS / Linux instructions:
- Docker (choose one):
- Desktop users: Docker Desktop
- Or Linux command line: Docker Engine
In a terminal window:
# Copy the SeedSigner OS repo to your local machine
git clone --recursive https://github.com/SeedSigner/seedsigner-os.git
# Move into the repo directory
cd seedsigner-os
# initialize and update submodules (buildroot)
git submodule init && git submodule updateForce Docker to build on a container meant to run on amd64 in order to get an identical result, even if your actual cpu is different:
export DOCKER_DEFAULT_PLATFORM=linux/amd64Select your board type from the Board configs list below.
If you're unsure, most people should specify pi0.
export BOARD_TYPE=pi0Start the build!
SS_ARGS="--$BOARD_TYPE --app-branch=0.7.0" docker compose up --force-recreate --buildBuilding can take 25min to 2.5hrs+ depending on your cpu and will require 20-30 GB of disk space.
Windows PowerShell instructions:
Recommend running these steps in WSL2 (Windows Subsystem for Linux) so that you can just follow the Linux steps below.
- Docker (choose one):
- Desktop users: Docker Desktop
- Or Linux command line: Docker Engine
- Windows PowerShell users may also need to install
git

# Copy the SeedSigner OS repo to your local machine

git submodule init && git submodule updateForce Docker to build on a container meant to run on amd64 in order to get an identical result, even if your actual cpu is different:
$env:DOCKER_DEFAULT_PLATFORM = 'linux/amd64'Select your board type from the Board configs list below.
If you're unsure, most people should specify pi0.
$env:BOARD_TYPE = 'pi0'Start the build!
# TODO: INCORRECT SYNTAX FOR POWERSHELL(?)
SS_ARGS="--%BOARD_TYPE% --app-branch=0.7.0" docker compose up --force-recreate --buildBuilding can take 25min to 2.5hrs+ depending on your cpu and will require 20-30 GB of disk space.
When the build completes you'll see:
seedsigner-os-build-images-1 | /opt/buildroot
seedsigner-os-build-images-1 | a380cb93eb852254863718a9c000be9ec30cee14a78fc0ec90708308c17c1b8a /opt/../images/seedsigner_os.0.7.0.pi0.img
seedsigner-os-build-images-1 exited with code 0The second line above lists the SHA256 hash of the image file that was built. This hash should match the hash of the release image published on the main github repo. If the hashes match, then you have successfully confirmed the reproducible build!
The completed image file will be in the images subdirectory.
