Open-source charts

You can use open-source Helm charts in your application. At deployment time, Release will add the Helm repository and install its dependencies.

Here's an example showing how you can define an application that will use both Elasticsearch and Vault open-source Helm charts:

charts:
- name: elasticsearch
  add: elastic
  install: elastic/elasticsearch
  repo_url: https://helm.elastic.co
  directory: helm/elasticsearch
  values: 
  - values.yaml
- name: vault
  repo_url: https://helm.releases.hashicorp.com
  add: hashicorp
  install: hashicorp/vault
  directory: helm/hashicorp
  values: 
  - values.yml

Release will use the values files located in your source control repository. By default, Release will look for the values files in the root of the repository, but you can define a directory where the values files are located in your source control repository.

Once you've configured the charts, you can use them in a workflow. Workflows allow you to run the Helm charts in parallel and orchestrate the deployment of all your services.

Here's an example workflow that deploys Elasticsearch and Vault in parallel:

workflows:
- name: setup
  parallelize:
  - step: opensource-backend
    tasks:
    - charts.elasticsearch
    - charts.vault
- name: patch
  parallelize:
  - step: opensource-backend
    tasks:
    - charts.elasticsearch
    - charts.vault
