helm push plugin
Helm plugin to push chart package to ChartMuseum
Install
Based on the version in plugin.yaml, release binary will be downloaded from GitHub:
$ helm plugin install https://github.com/chartmuseum/helm-push
Downloading and installing helm-push v0.2.1 ...
https://github.com/chartmuseum/helm-push/releases/download/v0.2.1/helm-push_0.2.1_darwin_amd64.tar.gz
Installed plugin: push
Usage
You must start by adding a ChartMuseum-backed repo via Helm CLI (if not already added)
$ helm repo add chartmuseum http://localhost:8080
For all available plugin options, please run
$ helm push --help
Pushing a directory
Point to a directory containing a valid Chart.yaml and the chart will be packaged and uploaded:
$ cat mychart/Chart.yaml
name: mychart
version: 0.3.2
$ helm push mychart/ chartmuseum
Pushing mychart-0.3.2.tgz to chartmuseum...
Done.
Pushing with a custom version
The --version flag can be provided, which will push the package with a custom version.
Here is an example using the last git commit id as the version:
$ helm push mychart/ --version="$(git log -1 --pretty=format:%h)" chartmuseum
Pushing mychart-5abbbf28.tgz to chartmuseum...
Done.
If you want to enable something like --version="latest", which you intend to push regularly, you will need to run your ChartMuseum server with ALLOW_OVERWRITE=true.
Push .tgz package
This workflow does not require the use of helm package, but pushing .tgzs is still suppported:
$ helm push mychart-0.3.2.tgz chartmuseum
Pushing mychart-0.3.2.tgz to chartmuseum...
Done.
Authentication
Basic Auth
If you have added your repo with the --username/--password flags (Helm 2.9+), or have added your repo with the basic auth username/password in the URL (e.g. https://myuser:mypass@my.chart.repo.com), no further setup is required.
The plugin will use the auth info located in ~/.helm/repository/repositories.yaml in order to authenticate.
If you are running ChartMuseum with AUTH_ANONYMOUS_GET=true, and have added your repo without authentication, the plugin recognizes the following environment variables for basic auth on push operations:
$ export HELM_REPO_USERNAME="myuser"
$ export HELM_REPO_PASSWORD="mypass"
With this setup, you can enable people to use your repo for installing charts etc. without allowing them to upload to it.
Token
Although ChartMuseum server does not define or accept a token format (yet), if you are running it behind a proxy that accepts access tokens, you can provide the following env var:
$ export HELM_REPO_ACCESS_TOKEN="<token>"
This will result in all basic auth options above being ignored, and the plugin will send the token in the header:
Authorization: Bearer <token>
Custom Downloader
This plugin also defines the cm:// protocol that you may specify when adding a repo:
$ helm repo add chartmuseum cm://my.chart.repo.com
The only real difference with this vs. simply using http/https, is that the environment variables above are recognized by the plugin and used to set the Authorization header appropriately. As in, if you do not add your repo in this way, you are unable to use token-based auth for GET requests (downloading index.yaml, chart .tgzs, etc).
By default, cm:// translates to https://. If you must use http://, you can set the following env var:
$ export HELM_REPO_USE_HTTP="true"
