Astronomer CLI Installation for Windows 10

Welcome to Astronomer!

If you're a Windows User looking to install and use the Astronomer CLI, you have 2 options:

  1. Install the Unix-based CLI a Windows Subsystem for Linux (WSL)
  2. Install the Windows-based CLI

Note: Either option will require Windows 10 or greater.

Astronomer CLI on Windows Subsystem for Linux (WSL)

This guide will walk you through the setup and configuration process for using the Astronomer CLI in the Windows Subsystem for Linux (WSL) on Windows 10. Before you start, make sure:

  • You're running the bash terminal
  • You have the the WSL enabled
  • You're on Windows 10

Note: We use Ubuntu as our Linux flavor of choice, but this guide should work for other distributions as well.

Much of the setup process is borrowed from a guide written by Nick Janetakis. Find the full guide here: Setting Up Docker for Windows and WSL to Work Flawlessly

Step 1. Install Docker CE for Windows

Follow the Docker for Windows Install Guide.

Step 2. Expose the Docker Daemon

In your docker settings, under general, enable the Expose daemon on tcp://localhost:2375 without TLS setting.

This will allow the docker daemon running on windows to act as a remote docker service for our WSL instance.

Step 3. Install Docker for Linux in WSL

In your WSL terminal, follow the Docker CE for Ubuntu install guide here: Install Docker CE for Ubuntu

Docker will not run in the WSL instance, however this will give us access to the docker CLI through our Linux environment.

Step 4. Connect your WSL instance to Docker on Windows

Now, you need to point our docker host route to the remote docker daemon running in Windows. To do this we need to add an export path to our ~/.bashrc file.

Run: echo "export DOCKER_HOST=tcp://" >> ~/.bashrc && source ~/.bashrc to add a new line to your bashrc file pointing the docker host to your exposed daemon and re-source your bashrc file.

Step 5. Custom Mount Points

To ensure docker can properly mount volumes, we need to create custom mount paths that work in the WSL instance.

This process differs depending on the version of Windows 10 you're running. In our case, we're running build 1709.

First, create a new mount point directory:

sudo mkdir /c

Then bind this mount point:

sudo mount --bind /mnt/c /c

You're all set! You can now run docker run hello-world through your WSL instance to ensure everything works as expected. Keep in mind that you will need to bind your mount point each time you start up a new WSL instance.

Last thing: Whenever you run Docker-compose up, you'll want to make sure you navigate to the /c/Users/name/dev/myapplication first, otherwise your volume won't work. In other words, never access /mnt/c directly.

Step 6. Final Install

Once you've completed the steps above, head over to our CLI Quickstart Guide to finish the installation and start deployment DAGs.

Astronomer CLI on Windows 10

If for any reason you can't install WSL, you can install a Windows adapted version of the Astronomer CLI directly by following the instructions below.

Step 1. Pre-Flight Checklist

Make sure you have the following installed:

Step 2. Enable Hyper-V

Make sure you enabled Hyper-V, which is required to run Docker and Linux Containers.

If you have any issues with Docker, check out Docker's Troubleshooting Guide for Windows.

Step 3. Download the Astronomer CLI

Currently, Astronomer on Windows outside of WSL is only supported by Astronomer CLI versions 0.8 and beyond.

You can download the latest version of the CLI here.

Step 4. Extract the contents

After following step 3, you should see a zip file on your machine that contains the following:

  • A file titled astro.exe

Grab that astro.exe file and move it to a location that won't be deleted.

Step 5. Extract the contents

Add the location of astro.exe in your %PATH%. If you don't know how to do this, check out this helpful guide.

Step 6. Final Command

Now, open your Terminal or PowerShell console and run the following:

C:\Windows\system32>astro version
Astronomer CLI Version: 0.8.2
Git Commit: f5cdab8f832da3c6184a7ac167b491e3bac3c022

If you get a response like the above, you're all set! Happy Airflow-ing.

Potential Postgres Error

As a Windows user, you might see the following error when trying to call astro dev start on your newly created workspace:

This is an issue pulling Postgres that should be fixed by running the following:
