Implementation of a command to fetch pre-built images from a remote registry, complementing the --push-images option already present on build-containers. The two subcommands used together allow a stack to be deployed without needing to built its images, provided they have been already built and pushed to the specified container image registry. This implementation simply picks the newest image with the right name and platform (matches against the platform Python is running on, so watch out for scenarios where Python is an x86 binary on M1 macs).

Stack Orchestrator
Stack Orchestrator allows building and deployment of a Laconic Stack on a single machine with minimial prerequisites. It is a Python3 CLI tool that runs on any OS with Python3 and Docker. The following diagram summarizes the relevant repositories in the Laconic Stack - and the relationship to Stack Orchestrator.
Install
To get started quickly on a fresh Ubuntu instance (e.g, Digital Ocean); try this script. WARNING: always review scripts prior to running them so that you know what is happening on your machine.
For any other installation, follow along below and adapt these instructions based on the specifics of your system.
Ensure that the following are already installed:
- Python3:
python3 --version>=3.8.10(the Python3 shipped in Ubuntu 20+ is good to go) - Docker:
docker --version>=20.10.21 - jq:
jq --version>=1.5 - git:
git --version>=2.10.3
Note: if installing docker-compose via package manager on Linux (as opposed to Docker Desktop), you must install the plugin, e.g. :
mkdir -p ~/.docker/cli-plugins
curl -SL https://github.com/docker/compose/releases/download/v2.11.2/docker-compose-linux-x86_64 -o ~/.docker/cli-plugins/docker-compose
chmod +x ~/.docker/cli-plugins/docker-compose
Next decide on a directory where you would like to put the stack-orchestrator program. Typically this would be
a "user" binary directory such as ~/bin or perhaps /usr/local/laconic or possibly just the current working directory.
Now, having selected that directory, download the latest release from this page into it (we're using ~/bin below for concreteness but edit to suit if you selected a different directory). Also be sure that the destination directory exists and is writable:
curl -L -o ~/bin/laconic-so https://git.vdb.to/cerc-io/stack-orchestrator/releases/download/latest/laconic-so
Give it execute permissions:
chmod +x ~/bin/laconic-so
Ensure laconic-so is on the PATH
Verify operation (your version will probably be different, just check here that you see some version output and not an error):
laconic-so version
Version: 1.1.0-7a607c2-202304260513
Save the distribution url to ~/.laconic-so/config.yml:
mkdir ~/.laconic-so
echo "distribution-url: https://git.vdb.to/cerc-io/stack-orchestrator/releases/download/latest/laconic-so" > ~/.laconic-so/config.yml
Update
If Stack Orchestrator was installed using the process described above, it is able to subsequently self-update to the current latest version by running:
laconic-so update
Usage
The various stacks each contain instructions for running different stacks based on your use case. For example:
Contributing
See the CONTRIBUTING.md for developer mode install.
Platform Support
Native aarm64 is not currently supported. x64 emulation on ARM64 macos should work (not yet tested).
