Syncing Your Chart Repository

Note: This example is specifically for a Google Cloud Storage (GCS) bucket which serves a chart repository.

Prerequisites​

  • Install the gsutil tool. We rely heavily on the gsutil rsync functionality
  • Be sure to have access to the Helm binary
  • Optional: We recommend you set object versioning on your GCS bucket in case you accidentally delete something.

Set up a local chart repository directory​

Create a local directory like we did in the chart repository guide, and place your packaged charts in that directory.

For example:

$ mkdir fantastic-charts
$ mv alpine-0.1.0.tgz fantastic-charts/

Generate an updated index.yaml​

Use Helm to generate an updated index.yaml file by passing in the directory path and the url of the remote repository to the helm repo index command like this:

$ helm repo index fantastic-charts/ --url https://fantastic-charts.storage.googleapis.com

This will generate an updated index.yaml file and place it in the fantastic-charts/ directory.

Sync your local and remote chart repositories​

Upload the contents of the directory to your GCS bucket by running scripts/sync-repo.sh and pass in the local directory name and the GCS bucket name.

For example:

$ pwd
/Users/me/code/go/src/helm.sh/helm
$ scripts/sync-repo.sh fantastic-charts/ fantastic-charts

Verifying Prerequisites....
Thumbs up! Looks like you have gsutil. Let's continue.

Starting synchronization
Would copy file://fantastic-charts/alpine-0.1.0.tgz to gs://fantastic-charts/alpine-0.1.0.tgz
Would copy file://fantastic-charts/index.yaml to gs://fantastic-charts/index.yaml

Congratulations your remote chart repository now matches the contents of fantastic-charts/

Updating your chart repository​

You'll want to keep a local copy of the contents of your chart repository or use gsutil rsync to copy the contents of your remote chart repository to a local directory.

For example:

$ gsutil rsync -d -n gs://bucket-name local-dir/    # the -n flag does a dry run

Starting synchronization
Would copy gs://bucket-name/alpine-0.1.0.tgz to file://local-dir/alpine-0.1.0.tgz
Would copy gs://bucket-name/index.yaml to file://local-dir/index.yaml

$ gsutil rsync -d gs://bucket-name local-dir/       # performs the copy actions
