Astronomer CLI

The Astronomer CLI can be used to build Airflow DAGs locally and run them via Docker-Compose, as well as to deploy those DAGs to Astronomer-managed Airflow clusters and interact with the Astronomer API in general.

Install

• via curl

  curl -sSL https://install.astronomer.io | sudo bash
  

Previous Versions

-via curl

curl -sSL https://install.astronomer.io | sudo bash -s -- [TAGNAME]

ie

curl -sSL https://install.astronomer.io | sudo bash -s -- v0.3.1

Note: If you get mkdir error during installation please download and run godownloader script locally.

$ cat godownloader.sh | bash -s -- -b /usr/local/bin

Getting Started

1. Confirm the install worked:

   $ astro
   

2. Create a project:

   $ mkdir hello-astro && cd hello-astro
   $ astro airflow init
   

This will generate a skeleton project directory:

.
├── dags
│   ├── example-dag.py
├── Dockerfile
├── include
├── packages.txt
├── plugins
└── requirements.txt

Dags can go in the dags folder, custom airflow plugins in plugins, python packages needed can go in requirements.txt, and OS level packages can go in packages.txt.

1. Start airflow

Run astro airflow start to start a local version of airflow on your machine. This will spin up a few locally running docker containers - one for the airflow scheduler, one for the webserver, and one for postgres. (Run docker ps to verify)

Help

The CLI includes a help command, descriptions, as well as usage info for subcommands.

To see the help overview:

$ astro help

Or for subcommands:

$ astro airflow --help

$ astro airflow deploy --help

Development

How to get started as a developer.

1. Build:

   $ git clone git@github.com:astronomerio/astro-cli.git
   $ cd astro-cli
   $ make build
   

2. (Optional) Install to $GOBIN:

   $ make install
   

3. Run:

   $ astro
   

Testing Locally

astro-cli is a single component of the much larger Astronomer Enterprise platform. In order to test locally you will need to

1. setup both houston-api and orbit-ui.
2. edit your global or project config to enable local development

ex.

local:
  enabled: true
  houston: http://localhost:8870/v1
  orbit: http://localhost:5000

Docs

Docs (/docs) are generated using the github.com/spf13/cobra/doc pkg. Currently this pkg is broken with go vendoring, the following instructions include a workaround

1. Remove the /vendor/github.com/spf13/cobra pkg, forcing Go to search your go path for the package instead
2. go run gendocs/gendocs.go
3. restore /vendor/github.com/spf13/cobra

Versioning

Astronomer Enterprise is under very active development. Because of this we cannot make backwards compatibility guarantees between versions.

THe astro-cli is following a semantic versioning scheme

{MAJOR_RELEASE}.{MINOR_RELEASE}.{PATCH_RELEASE}

with all releases up until 1.0.0 considered beta.

Compatibility

Starting with v0.3.3 the astro-cli began tightly tracking the platform release versioning, this means that compatibility is only guaranteed between matching minor versions of the platform and the astro-cli.

ie. astro-cli v0.4.0 is guaranteed to be compatible with houston-api v0.4.x but with houston-api v0.5.x

Note

These changes were introduced platform wide with v0.4.0
