Manage packages

This page explains how to manage packages with Config Sync from the Google Cloud console.

A package is a set of Kubernetes resource object manifests that are managed in a source of truth and synced to a cluster by Config Sync. Each package definition is contained in a RootSync or RepoSync object on the cluster. For more detailed information about RootSync and RepoSync objects, see Config Sync architecture.

Before you begin

Deploy a package

After you have registered your clusters to a fleet and installed Config Sync, you can configure Config Sync to deploy a package to a cluster from a source of truth. You can deploy the same package to multiple clusters or deploy different packages to different clusters. You can edit a package after deploying it, except for some settings like package name and sync type. For more information, see Manage packages.

To deploy a package, complete the following steps:

  1. In the Google Cloud console, go to the Config Sync dashboard.

    Go to Config Sync dashboard

  2. Click Deploy Package.

  3. In the Select clusters for package deployment table, select the cluster that you want to deploy a package to and then click Continue.

  4. Select either Package hosted on Git or Package hosted on OCI as your source type and then click Continue.

  5. In the Package details section, enter a Package name, which identifies the RootSync or RepoSync object.

  6. In the Sync type field, choose either Cluster scoped sync or Namespace scoped sync as the sync type.

    Cluster scoped sync creates a RootSync object and Namespace scoped sync creates a RepoSync object. For more information about these objects, see Config Sync architecture.

  7. In the Source section, complete the following:

    • For sources hosted in a Git repository, enter the following fields:

      1. Enter the URL of the Git repository that you're using as a source of truth as the Repository URL.
      2. Optional: Update the Revision field to check out if you're not using the default HEAD.
      3. Optional: Update the Path field if you don't want to sync from the root repository.
      4. Optional: Update the Branch field if you're not using the default main branch.

    • For sources hosted in an OCI image, enter the following fields:

      1. Enter the URL of the OCI image that you're using as a source of truth as the Image.
      2. Enter the path of the directory to sync from, relative to the root directory, as the Directory.

  8. (Optional): Expand the Advanced settings section to complete the following:

    1. Select an Authentication type. Config Sync needs read-only access to your source of truth to read the configuration files in the source and apply them to your clusters. Unless your source requires no authentication, such as a public repository, ensure that you grant Config Sync read-only access to your Git repository, OCI image, or Helm chart (gcloud CLI only). Choose the same authentication type that you configured when you installed Config Sync:

      • None: Use no authentication.
      • SSH: Authenticate by using an SSH key pair.
      • Cookiefile: Authenticate by using a cookiefile.
      • Token: Authenticate by using an access token or password.
      • Google Cloud Repository: Use a Google service account to access a Cloud Source Repositories repository. Only select this option if Workload Identity Federation for GKE is not enabled in your cluster.
      • Workload Identity: Use a Google service account to access a Cloud Source Repositories repository.

    2. Enter a number in seconds to set the Sync wait time, which determines how long Config Sync waits between attempts to pull from the source of truth.

    3. Enter a Git proxy URL for the HTTPS proxy to be used when communicating with the source of truth.

    4. Choose Hierarchy to change the Source format.

      The default value Unstructured is recommended in most cases since it lets you organize your source of truth however you want.

  9. Click Deploy Package.

    You are redirected to the Config Sync Packages page. After a few minutes, you should see Synced in the Sync status column for the cluster that you configured.

Edit a package

To edit a package that you've already deployed, complete the following steps:

  1. In the Google Cloud console, go to the Config Sync Packages tab.

    Go to Packages

  2. (Optional): Expand the Quick filters menu and then select a filter to help find the package that you want to edit.

  3. Expand the package name that you want to edit and then, in the row that contains the cluster name, click the context menu and then click Edit package.

  4. Review and update the package settings that you want to change.

  5. Click Save.

Uninstall a package

To uninstall a package from the Google Cloud console, complete the following steps:

  1. In the Google Cloud console, go to the Config Sync Packages tab.

    Go to Packages

  2. (Optional): Expand the Quick filters menu and then select a filter to help find the package that you want to uninstall.

  3. Expand the package name that you want to uninstall and then, in the row that contains the cluster name, click the context menu and then click Uninstall package.

  4. In the confirmation dialog, select whether to uninstall only the RootSync or RepoSync object, or uninstall the RootSync or RepoSync and all of the resources managed by the RootSync or RepoSync.

  5. Type the confirmation message and then click Uninstall.
