jovykit 1.1.1

Layered Jupyter container images and project-local JovyKit environments.

JovyKit

JovyKit provides layered Jupyter notebook container images for data science, machine learning, and research workflows.

The images are designed as progressively larger environments, so users can pick the smallest image that fits their workload:

• minimal: Jupyter runtime plus the core scientific Python stack.
• base: everyday data science, classical machine learning, statistics, and local data access.
• extended: advanced machine learning, NLP, time series, distributed compute, and API tooling.
• full: heavy frameworks, generative AI tooling, graph and geospatial analysis, big data, and additional research utilities.

Images

Published image variants use the following naming pattern:

ghcr.io/mihneateodorstoica/jovykit-TYPE:latest
ghcr.io/mihneateodorstoica/jovykit-TYPE:nightly
ghcr.io/mihneateodorstoica/jovykit-TYPE:lts

TYPE is one of minimal, base, extended, or full.

All image variations include client-side SSH tooling for Git remotes, file copying, and SSH-backed sync:

• ssh, scp, and sftp from OpenSSH
• git
• rsync

Build Locally

Build a specific image target from the repository root:

docker build --target minimal -t jovykit-minimal ./image
docker build --target base -t jovykit-base ./image
docker build --target extended -t jovykit-extended ./image
docker build --target full -t jovykit-full ./image

CLI

JovyKit includes a CLI for project-local container environments. The mental model is:

.jovy is to JovyKit what .venv is to Python.

Create an environment, add project packages, and run Jupyter:

jovy init .jovy --image base --gpus auto
jovy add pandas scikit-learn plotly
jovy run

The CLI creates a local work/ directory for project files and writes a root jovy.toml plus a reproducible overlay build recipe under .jovy/:

jovy.toml
work/
.jovy/
  requirements.txt
  Containerfile
  compose.yaml
  state.json

Useful commands:

jovy --version
jovy status
jovy status --json
jovy build --pull
jovy sync --no-build
jovy start --no-build
jovy run --watch
jovy logs --tail 100 --since 10m --timestamps --no-follow
jovy shell -c "python --version"
jovy exec python --version
jovy stop --timeout 10
jovy destroy --keep-image

Most commands accept --env PATH when you want to operate on a JovyKit environment outside the current project tree. jovy init also supports customizing the generated project name, overlay image name/tag, Jupyter port, GPU mode, Jupyter token/log level, and mounted work directory. Docker Compose watch runs with jovy run; jovy start stays detached and starts a lightweight watcher that restarts the container when jovy.toml changes.

jovy.toml can also customize runtime environment variables, extra volumes, restart policy, Jupyter command/logging, Compose Watch behavior, image build arguments, build target/platform, apt packages, and uv/pip install options.
