helmvendor

This tool is extracted from tanka. It is intended to act as the missing "vendor" sub-command of the helm CLI.

It is equivalent to tk tool charts, with all of the jsonnet specific functionality removed.

Helmvendor

Helm does not make vendoring incredibly easy by itself. helm pull provides the required plumbing, but it does not record its actions in a reproducible manner.

Installation

Using the go toolchain:

$ go install github.com/baranyildirim/helmvendor@latest

Create a chartfile.yaml, install charts

Start by creating a chartfile using the init command:

$ helmvendor init

To add a chart, use the following:

$ helmvendor add <repo>/<name>@<version>

This will also call `helmvendor vendor``, so that the charts/ directory is updated.

For example, to install the MySQL chart at version 1.6.7 from the stable repository:

$ helmvendor add stable/mysql@1.6.7

Add repository

By default, the stable repository is automatically set up for you. If you wish to add another repository, you can use the add-repo command:

$ helmvendor charts add-repo grafana https://grafana.github.io/helm-charts

Another way is to modify chartfile.yaml directly:

version: 1
repositories:
  - name: stable
    url: https://charts.helm.sh/stable
+ - name: grafana
+   url: https://grafana.github.io/helm-charts

Installing multiple versions of the same chart: If you wish to install multiple versions of the same chart, you can write them to a specific directory. You can do so with a : suffix in the add command, or by modifying the chartfile manually.

helmvendor add stable/mysql@1.6.7:1.6.7
helmvendor add stable/mysql@1.6.8:1.6.8

The resulting chartfile will look like this:

version: 1
directory: charts
repositories:
- name: stable
  url: https://charts.helm.sh/stable
requires:
- chart: stable/mysql
  directory: 1.6.7
  version: 1.6.7
- chart: stable/mysql
  directory: 1.6.8
  version: 1.6.8

Install charts from chartfile

To install charts from an existing chartfile, use the following:

$ helmvendor vendor

Optionally, you can also pass the --prune flag to remove vendored charts that are no longer in the chartfile.
