Helm 3 Preview: Charting Our Future – Part 6: Introducing Library Charts
Thu, May 9, 2019
This is part 6 of 7 of our Helm 3 Preview: Charting Our Future blog series on library charts. You can find our previous blog post on the Helm chart dependencies here.
Helm 3 supports a class of chart called a "library chart". This is a chart that is shared by other charts, but does not create any release artifacts of its own. A library chart's templates can only declare define elements. Globally scoped non-define content is simply ignored. This allows users to re-use and share snippets of code that can be re-used across many charts, avoiding redundancy and keeping charts
DRY.
Library charts are declared in the dependencies directive in Chart.yaml, and are installed and managed like any other chart.
dependencies:
- name: mylib
version: 1.x.x
repository: quay.io
We're very excited to see the use cases this feature opens up for chart developers, as well as any best practices that arise from consuming library charts.
