Helm push artifactory plugin

A Helm plugin to push helm charts to artifactory:

• A version for artifactory of helm-push: https://github.com/chartmuseum/helm-push
• Using a couple of things from Jfrog-cli-go: https://github.com/jfrog/jfrog-cli-go
• And a bit of makefile magic from: https://github.com/helm/helm

Install

IMPORTANT: by default helm plugin install will install the version from the master branch, and that version is for Helm v2, if you are using Helm v3 please add --version 1.0.1 (or the version you want to use) to your helm plugin install command. Also please always use the flag --version in your CI/CD system to avoid surprises when new changes are merged to master!

Based on the version in plugin.yaml, release binary will be downloaded from GitHub:

$ helm plugin install https://github.com/belitre/helm-push-artifactory-plugin

Uninstall

helm plugin remove push-artifactory
Removed plugin: push-artifactory

Local and virtual repositories

Artifactory has two types of repositories: local and virtual. Local repositories are the ones where you push the charts, but to get a chart you'll need to use a virtual repository!

This plugin works with local repositories, you can add them through the Helm CLI like a virtual repository and use it later instead of the URL. But remember: you won't be able to get charts from a local repository

Example:

• We can add our local repository with helm CLI:

  $ helm repo add --username myuser --password mypass my-local-repo https://artifactoryhost/my-local-repo
  "my-local-repo" has been added to your repositories

• We can use this repository later to push charts:

  $ helm push-artifactory mychart-0.3.2.tgz my-local-repo 
  Pushing mychart-0.3.2.tgz to https://artifactoryhost/my-local-repo/mychart/mychart-0.3.2.tgz...
  Done.
  Reindex helm repository my-local-repo...
  Reindex of helm repo my-local-repo was scheduled to run.

• We can't get the helm chart from a local repo:

  $ helm fetch my-local-repo/mychart
  Error: Get local://mychart/mychart-0.3.2.tgz: unsupported protocol scheme "local"

• We can add the virtual repo and get the chart:

  $ helm repo add --username myuser --password mypass my-virtual-repo https://artifactoryhost/my-virtual-repo
  "my-virtual-repo" has been added to your repositories
  $ helm repo update
  Hang tight while we grab the latest from your chart repositories...
  ...Skip local chart repository
  ...Successfully got an update from the "my-local-repo" chart repository
  ...Successfully got an update from the "my-virtual-repo" chart repository
  Update Complete. ⎈ Happy Helming!⎈ 
  $ helm fetch my-virtual-repo/mychart
  $ ls
  mychart-0.3.2.tgz

Usage

Example using URL:

$ helm push-artifactory /my/chart/folder https://my-artifactory/my-local-repo --username username --password password

Example using helm repo added through CLI:

$ helm push-artifactory /my/chart/folder my-local-repo

For all available plugin options, please run:

$ helm push-artifactory --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-artifactory mychart/ https://my-artifactory/my-local-repo
Pushing mychart-0.3.2.tgz to https://my-artifactory/my-local-repo/mychart/mychart-0.3.2.tgz...
Done.
Reindex helm repository my-local-repo...
Reindex of helm repo my-local-repo was scheduled to run.

Pushing with a custom version

The --version or -v 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-artifactory mychart/ --version="$(git log -1 --pretty=format:%h)" https://my-artifactory/my-local-repo
Pushing mychart-5abbbf28.tgz to https://my-artifactory/my-local-repo/mychart/mychart-5abbbf28.tgz...
Done.
Reindex helm repository my-local-repo...
Reindex of helm repo my-local-repo was scheduled to run.

Pushing overriding values

The --set or -s flag can be provided, which will push the package overriding values in the values.yaml file.

Here is an example using a custom version and default image tag:

$ helm push-artifactory mychart/ -v="0.5.1" -s image.tag="0.5.1" https://my-artifactory/my-local-repo
Pushing mychart-0.5.1.tgz to https://my-artifactory/my-local-repo/mychart/mychart-0.5.1.tgz...
Done.
Reindex helm repository my-local-repo...
Reindex of helm repo my-local-repo was scheduled to run.

If we check the values.yaml of the chart we'll find:

image:
  tag: 0.5.1

We can override multiple values:

$ helm push-artifactory mychart/ -v="0.5.1" -s image.tag="0.5.1" -s service.name="my-custom-name" https://my-artifactory/my-local-repo
Pushing mychart-0.5.1.tgz to https://my-artifactory/my-local-repo/mychart/mychart-0.5.1.tgz...
Done.
Reindex helm repository my-local-repo...
Reindex of helm repo my-local-repo was scheduled to run.

This will set in values.yaml:

image:
  tag: 0.5.1
service:
  name: my-custom-name

Push .tgz package

This workflow does not require the use of helm package, but pushing .tgz is still supported:

$ helm push-artifactory mychart-0.3.2.tgz https://my-artifactory/my-local-repo
Pushing mychart-0.3.2.tgz to https://my-artifactory/my-local-repo/mychart/mychart-0.3.2.tgz...
Done.
Reindex helm repository my-local-repo...
Reindex of helm repo my-local-repo was scheduled to run.

Push with path

You can set a path to push your chart in your Artifactory local repository:

$ helm push-artifactory mychart/ https://my-artifactory/my-local-repo --path organization
Pushing mychart-0.3.2.tgz to https://my-artifactory/my-local-repo/organization/mychart/mychart-0.3.2.tgz...
Done.
Reindex helm repository my-local-repo...
Reindex of helm repo my-local-repo was scheduled to run.

Skip repository reindex

You can skip triggering the repository reindex:

$ helm push-artifactory mychart/ https://my-artifactory/my-local-repo --skip-reindex
Pushing mychart-0.3.2.tgz to https://my-artifactory/my-local-repo/mychart/mychart-0.3.2.tgz...
Done.

Authentication

Basic Auth

The plugin will not use the auth info located in ~/.helm/repository/repositories.yaml in order to authenticate.

You can provide username and password through commmand line with --username username --password password or use the following environment variables for basic auth on push operations:

$ export HELM_REPO_USERNAME="myuser"
$ export HELM_REPO_PASSWORD="mypass"

Access Token

You can provide an access token through command line with --access-token my-token or use the following env var:

$ export HELM_REPO_ACCESS_TOKEN="<token>"

If only the access token is supplied without any username, the plugin will send the token in the header:

Authorization: Bearer <token>

If a username is supplied with an access token, the plugin will use basic authentication, using the access token as password for the user.

Api Key

You can provide an api key through command line with --api-key my-key or use the following env var:

$ export HELM_REPO_API_KEY="<api-key>"

If only the api key is supplied without any username, the plugin will send the api key in the header:

X-JFrog-Art-Api: <api-key>

If a username is supplied with an api key, the plugin will use basic authentication, using the api key as password for the user.

TLS Client Cert Auth

If you need to setup your TLS cert authentication, the following options are available:

--ca-file string    Verify certificates of HTTPS-enabled servers using this CA bundle [$HELM_REPO_CA_FILE]
--cert-file string  Identify HTTPS client using this SSL certificate file [$HELM_REPO_CERT_FILE]
--key-file string   Identify HTTPS client using this SSL key file [$HELM_REPO_KEY_FILE]
--insecure          Connect to server with an insecure way by skipping certificate verification [$HELM_REPO_INSECURE]
