Astronomer Platform Helm Charts
This repository contains the helm charts for deploying the Astronomer Platform into a Kubernetes cluster.
Astronomer is a commercial "Airflow as a Service" platform that runs on Kubernetes. Source code is made available for the benefit of our customers, if you'd like to use the platform reach out for a license or try out Astronomer Cloud.
Docker images for deploying and running Astronomer are currently available on DockerHub.
The Astronomer Platform documentation is located at https://www.astronomer.io/docs/
We welcome any contributions:
- Report all enhancements, bugs, and tasks as GitHub issues
- Provide fixes or enhancements by opening pull requests in Github
Install the following tools:
- docker (make sure your user has permissions - try 'docker ps')
- mkcert (make sure mkcert in PATH)
Run this script from the root of this repository:
For MacOS, if kind version >=0.8.1, use the following command
Each time you run the script, the platform will be fully reset to the current helm chart.
Customizing the local deployment
Turn on or off parts of the platform
Modify the "tags:" in configs/local-dev.yaml
- platform: core Astronomer components
- logging (large impact on RAM use): ElasticSearch, Kibana, Fluentd (aka 'EFK' stack)
- monitoring: Prometheus
- kubed: leave on
Add a Docker image into KinD's nodes (so it's available for pods):
kind load docker-image $your_local_image_name_with_tag
Make use of that image:
Make note of your pod name
kubectl get pods -n astronomer
Find the corresponding deployment, daemonset, or statefulset
kubectl get deployment -n astronomer
Replace the pod with the new image Look for "image" on the appropriate container and replace with the local tag, and set the pull policy to "Never".
kubectl edit deployment -n astronomer <your deployment>
Change Kubernetes version:
bin/reset-local-dev -K 1.16.3
Locally test HA configurations:
You need a powerful computer to run the HA testing locally. 28 GB or more of memory should be available to Docker.
- USE_HA: when set, will deploy using HA configurations
- CORDON_NODE: when set, will cordon this node after kind create cluster
- MULTI_NODE: when set, will deploy kind with two worker nodes
- Use bin/run-ci to start the cluster
- Modify / use bin/drain.sh to test draining
export USE_HA=1 export CORDON_NODE=kind-worker export MULTI_NODE=1 bin/run-ci
After the platform is up, then do
Usage of Astronomer code requires an Astronomer Platform Enterprise Edition license.
