Datadog is a helm plugin to annotate deployments with datadog specific annotation to map deployed resource to their location. You can read more about it in the documentation.

Helm 4 introduced a new plugin system that requires splitting plugins into multiple packages when they have multiple capabilities.

datadog: A plugin that adds add cli command support. datadog-post-renderer: A plugin that adds annotations in post-rendering.

Both plugins needs to be installed using following commands (note verification is enabeld):

helm plugin install https://github.com/DataDog/helm-plugin/releases/download/v0.1.3/datadog-0.1.3.tgz --verify=false

helm plugin install https://github.com/DataDog/helm-plugin/releases/download/v0.1.3/datadog-post-renderer-0.1.3.tgz --verify=false

Note that verification is disabled for now, but we are working on enabling it.

Please check latest release version here: https://github.com/DataDog/helm-plugin/releases

Verification of plugins is supported in Helm 4 and enabled by default. You can choose to skip verification of the plugins during installation by adding the --verify=false flag.

Install a specific version (recommend).

The --version flag is not supported in Helm 4, so you need to specify the exact download URL for the desired version.

Install a specific version (recommend):

helm plugin install https://github.com/DataDog/helm-plugin --version vX.Y.Z

Please check latest release version here: https://github.com/DataDog/helm-plugin/releases

Install latest version from main branch:

helm plugin install https://github.com/DataDog/helm-plugin

If you have issues installing the plugin you can debug it by addind environment variable: HELM_DEBUG=1

Example: HELM_DEBUG=1 helm plugin install https://github.com/DataDog/helm-plugin

If you already using helm to manage your deployments then switching to use the plugin could be done just by adding a call to the plugin:

Regular Helm call: helm install <release> <chart/path> <flags>

Helm call using plugin: helm datadog <plugin flags> install <release> <chart/path> <flags>

Helm plugins cannot be enabled by default. However, you can make the experience more seamless by defining an alias: alias helm=helm datadog
