mrp

Deploy, launch, manage, and orchestrate heterogeneous robots with ease!

Install

Before installing, you'll need python3+pip, conda, and docker. The later two only if using the runtime.

pip install mrp

Commands

up

Starts all defined processes, or a given subset.

# To bring up all the processes:
mrp up
# To bring up myproc:
mrp up myproc

down

Stops all defined processes, or a given subset.

# To bring down all the processes:
mrp down
# To bring down myproc:
mrp down myproc

logs

All the processes default to running in the background. To see the stdout:

# Attach to the log stream of all processes:
mrp logs
# Attach to the log stream of myproc:
mrp logs myproc
# Attach to the log stream of all processes, starting from the beginning:
mrp logs --old

ps

See the state of running processes:

mrp ps

Runtime

Host

Run a process without sandboxing:

mrp.process(
    name="proc",
    runtime=mrp.Host(
        run_command=["python3", "proc.py"],
    ),
)

Conda

Run a process within a conda environment:

mrp.process(
    name="proc",
    runtime=mrp.Conda(
        yaml="env.yml",
        run_command=["python3", "proc.py"],
    ),
)

The environment can be provided as a yaml file, local env name, or a list of channels and dependencies.

Docker

mrp.process(
    name="api",
    runtime=mrp.Docker(image="ghcr.io/alephzero/api:latest"),
)

The environment can be provided as a dockerfile or image name.

Mount points can be added with

runtime=mrp.Docker(
    image="ghcr.io/alephzero/log:latest",
    mount=["/tmp/logs:/tmp/logs"],
),

Other kwargs passed to Docker will be passed directly to the docker engine.

CLI Auto-Complete

Add the following snippet to your ~/.bashrc to get tab completion:

eval "$(_MRP_COMPLETE=bash_source mrp)"

Code Formatting

We use black and flake8 to lint our code. The formatting test will not pass if your code does not conform.

To make this easy for yourself, you can either

• Add the formattings to your IDE
• Install the git pre-commit hooks by running

  pip install pre-commit
  pre-commit install

To format manually, run: black .
