mapchete Hub CLI

A command line interface for mapchete Hub.

About mapchete Hub CLI

The mapchete Hub CLI provides a user-friendly command line interface (mhub) to interact with a running mapchete Hub instance. It simplifies the process of submitting, monitoring, and managing processing jobs without needing to write custom scripts or use tools like curl.

This CLI is the recommended tool for users who want to script workflows or manage mapchete Hub jobs from their terminal.

Key Features

• 💻 Full Job Lifecycle Management: Intuitive commands to execute, job (status), jobs (list), cancel, and retry processing jobs.

• ⚙️ Inspection: List available processes on a remote mapchete Hub and check remote package --remote-versions.

• 🔒 Authentication Support: Handles basic authentication via command line options (-u, -p) or environment variables.

• 🤖 Script-Friendly: Designed for easy integration into automated scripts and workflows.

Installation

Install the CLI and its dependencies from PyPI:

pip install mapchete-hub-cli

Quickstart

1. Point to your mapchete Hub

All commands require you to specify the mapchete Hub’s URL using the -h or --host option. If the mapchete Hub is running on the same machine with default settings (0.0.0.0:5000), you may not need this option.

2. List Available Processes

You can see what processes are available on the target mapchete Hub instance:

mhub -h 0.0.0.0:5000 processes

3. Prepare a mapchete File

Create a mapchete process file using YAML syntax. Note that all input and output paths must be absolute, as they are resolved on the remote server.

For example, hillshade.mapchete:

process: mapchete.processes.examples.hillshade
zoom_levels:
  - 10
pyramid:
  grid: geodetic
input:
  dem: https://data.example.com/path/to/dem.tif
output:
  path: s3://my-bucket/path/to/hillshade_output
  format: GTiff

4. Execute the Process

Use the execute command to send the job to the mapchete Hub.

mhub -h 0.0.0.0:5000 execute hillshade.mapchete

The mapchete Hub will return a unique job_id:

6227b68b-b7e6-4f40-a396-85763197f481

5. Check Job Status and Progress

Use the job_id with the job command to get a detailed status report, or progress for a quick look at the progress percentage.

# Get detailed status
mhub -h 0.0.0.0:5000 job 6227b68b-b7e6-4f40-a396-85763197f481

# Get just the progress
mhub -h 0.0.0.0:5000 progress 6227b68b-b7e6-4f40-a396-85763197f481

6. Manage Jobs

You can also list all jobs or cancel a running job:

# List all jobs on the mapchete Hub
mhub -h 0.0.0.0:5000 jobs

# Cancel a specific job
mhub -h 0.0.0.0:5000 cancel 6227b68b-b7e6-4f40-a396-85763197f481
