Grafana Dashboard Synchronizer

A small CLI tool to do a tag-base automatic synchornization and backup Grafana of dashboards across multiple Grafana instances.

This application can be used to synchronize dashboards, using a Git repository, across multiple Grafana instances.
A possible use cases:

  • Backup certain dashboards regularly using a Git repository
  • Push Grafana dashboards from one Grafana instance to a Git repository and import them into another Grafana instance. In addition, users can use tags to determine for themselves when a dashboard should be synchronized.
  • Preload new Grafana instances with predefined dashboards.

Example Usecase

This can be useful to stage dashboards from "dev" to "prod" environments.

Usage

The application can be used as follows:

$ ./grafana-dashboard-synchronizer [options]

By default, the application will use a configuration file named configuration.yml next to the binary. A custom configuration file can be used using the --config or -c option flag:

$ ./grafana-dashboard-synchronizer --config /custom/configuration.yml

In addition, a dry-run flag can be used. When the --dry-run flag is used, the application does not perform any modifications. This can be useful when testing what changes would be made.

$ ./grafana-dashboard-synchronizer --dry-run

By default, the application logs in an easy-to-read text format. With the --log-as-json flag, the application generates logs in JSON format, which is convenient if the logs are processed by other tools such as Logstash:

$ ./grafana-dashboard-synchronizer
  INFO[0000] Synchronizing Grafana dashboards...
  ...

compared to:

$ ./grafana-dashboard-synchronizer --log-as-json
  {"level":"info","msg":"Synchronizing Grafana dashboards...","time":"2022-02-08T16:41:26+01:00"}
  ...

Configuration

The configuration file can contain multiple jobs, which will be sequentially executed. Furthermore, the push (export) step of a job is executed before its pull (import) step.

See the following configuration for available configuration options:

- job-name:      "example-job"
  # API token to interact with the specified Grafana instance
  grafana-token: "eyJrIjoiSEp4dzhGdVBxMUhBdm..."
  # Base URL of the Grafana instance
  grafana-url:   "http://localhost:3000"
  # SSH-URL of the Git repository to use
  git-repository-url: "<GIT_REPOSITORY_URL>"
  # Private key to use for authentication against the Git repository
  private-key-file:   "<PRIVATE_SSH_KEY>"

  # push (export) related configurations
  push-configuration:
     # whether to export dashboards
     enable: true
     # the branch to use for exporting dashboards
     git-branch: "push-branch"
     # only dashboards with match this pattern will be considered in the sync process
     filter: ""
     # the tag to determine which dashboards should be exported
     tag-pattern: "agent"
     # whether the sync-tag should be kept during exporting
     push-tags: true

  # pull (import) related configurations  
  pull-configuration:
     # whether to import dashboards
     enable: true
     # the branch to use for importing dashboards
     git-branch: "pull-branch"
     # only dashboards with match this pattern will be considered in the sync process
     filter: ""

Development

Getting started

  1. Update and get dependencies:

    go mod tidy
  2. Build binaries for Linux, Windows and Darwin:

    mage -v
  3. List all available Mage targets for additional commands:

    mage -l

Releasing the Application

The release process of the application is automated using Github Actions. On each push to the main branch, a new prerelease is created and the corresponding commit is tagged "latest". Old prereleases will be deleted.

To create a normal release, the commit that is used as the basis for the release must be tagged with the following format: v*.*.*. After that, the release is built and created with the version number extracted from the tag. Furthermore, a new commit is created, which sets the current version in the main branch to the version that has been released.
