The Helm downloader plugin that provides GIT protocol support.
This fits multiple use cases:
- Need to keep charts private
- Doesn't want to package charts before installing
- Charts in a sub-path, or with another ref than
master
Use helm CLI to install this plugin:
$ helm plugin install https://github.com/aslafy-z/helm-git --version 0.8.1
To use the plugin, you only need git. If you want to build the plugin from source, or you want to contribute
to the plugin, please see these instructions.
$ helm plugin remove helm-git
helm-git will package any chart that is not so you can directly reference paths to original charts.
Here's the Git urls format, followed by examples:
git+https://[provider.com]/[user]/[repo]@[path/to/charts][?[ref=git-ref]&[sparse=0]]
git+ssh://git@[provider.com]/[user]/[repo]@[path/to/charts][?[ref=git-ref]&[sparse=0]]
git+file://[path/to/repo]@[path/to/charts][?[ref=git-ref]&[sparse=0]]
git+https://github.com/jetstack/cert-manager@deploy/charts?ref=v0.6.2&sparse=0
git+ssh://git@github.com/jetstack/cert-manager@deploy/charts?ref=v0.6.2&sparse=1
git+ssh://git@github.com/jetstack/cert-manager@deploy/charts?ref=v0.6.2
Add your repository:
$ helm repo add cert-manager git+https://github.com/jetstack/cert-manager@deploy/charts?ref=v0.6.2
You can use it as any other Helm chart repository. Try:
$ helm search cert-manager
NAME CHART VERSION APP VERSION DESCRIPTION
cert-manager/cert-manager v0.6.6 v0.6.2 A Helm chart for cert-manager
$ helm install cert-manager/cert-manager --version "0.6.6"
Fetching also works:
$ helm fetch cert-manager/cert-manager --version "0.6.6"
$ helm fetch git+https://github.com/jetstack/cert-manager@deploy/charts/cert-manager-v0.6.2.tgz?ref=v0.6.2
| name | description | default |
|---|---|---|
| ref | Set git ref to a branch or tag. Works also for commits with sparse=0 |
master |
| sparse | Set git strategy to sparse. Will try to fetch only the needed commits for the target path. | 1 |
As this plugin uses git CLI to clone repos. You can configure private access in the same manner that with any git repo.
- using ssh: Start a ssh-agent daemon
- using https: Use a credentials helper
You can enable debug output by setting HELM_GIT_DEBUG environment variable to 1:
HELM_GIT_DEBUG=1 helm repo add cert-manager git+https://github.com/jetstack/cert-manager@deploy/charts?ref=v0.6.2
In order to debug in a more efficient maneer, I advise you use helm fetch instead of helm repo add.
Contributions are welcome! Please see these instructions that will help you to develop the plugin.
