Redash

Redash is an open source tool built for teams to query, visualize and collaborate.

Introduction

This chart bootstraps a Redash deployment on a Kubernetes cluster using the Helm package manager.

This is a contributed project developed by volunteers and not officially supported by Redash.

Current chart version is 3.0.0-beta1

• https://github.com/getredash/redash

Prerequisites

• At least 3 GB of RAM available on your cluster
• Kubernetes 1.19+ - chart is tested with latest 3 stable versions
• Helm 3 (Helm 2 depreciated)
• PV provisioner support in the underlying infrastructure

Installing the Chart

To install the chart with the release name my-release, add the chart repository:

$ helm repo add redash https://getredash.github.io/contrib-helm-chart/

Create a values file with required secrets (store this securely!):

$ cat > my-values.yaml <<- EOM
redash:
  cookieSecret: $(openssl rand -base64 32)
  secretKey: $(openssl rand -base64 32)
postgresql:
  postgresqlPassword: $(openssl rand -base64 32)
redis:
  password: $(openssl rand -base64 32)
EOM

Install the chart:

$ helm upgrade --install -f my-values.yaml my-release redash/redash

The command deploys Redash on the Kubernetes cluster in the default configuration. The configuration section and and default values.yaml lists the parameters that can be configured during installation.

Tip: List all releases using helm list

Uninstalling the Chart

To uninstall/delete the my-release deployment:

$ helm delete my-release

The command removes all the Kubernetes components associated with the chart and deletes the release.

Upgrading

• See the changelog for major changes in each release
• The project will use the semver specification for chart version numbers (chart versions will not match Redash versions, since we may need to update the chart more than once for the same Redash release)
• Always back up your database before upgrading!
• Schema migrations will be run automatically after each upgrade

To upgrade a release named my-release:

helm repo update
helm upgrade --reuse-values my-release redash/redash

Below are notes on manual configuration changes or steps needed for major chart version updates.

From 2.x to 3.x

• The Redash version is updated from v8 to v10 (v9 never had a stable release)
• The upgrade should be automatic, but please test on a staging environment first!
• There are now additional “genericworker” and “scheduler” deployments, with associated configuration in values.yaml
• 3.x and higher will not run with Redash v8 - if you have overriden the image you will need to update that
• This chart now requires Kubernetes 1.19+
• Helm 2 is now depreciated and support will be removed in a future version

From 1.x to 2.x

• There are 3 required secrets (see above) that must now be specified in your release
• The server.env is now depreciated (except for non-standard variables such as PYTHON_*) to allow for better management of Redash configuration and secret values - any existing configuration should be migrated to the new values

From pre-release to 1.x

• The values.yaml structure has several changes
• The Redash, PostgreSQL and Redis versions have all been updated
• Due to these changes you will likely need to dump the database and reload it into a fresh install
• The chart now has it’s own repo: https://getredash.github.io/contrib-helm-chart/
