By default, the Datadog Helm chart uses the Agent 7 image that embeds the Python 3 runtime.

To keep the Datadog Agent updated, edit your datadog-values.yaml to remove any information under the agent.image and the clusterChecksRunner.image sections.

To use a specific container registry, set it with agent.image.repository and clusterChecksRunner.image.repository. Ensure that agents.image.tag and clusterChecksRunner.image.tag are undefined.

The default registry is gcr.io/datadoghq/agent.

agent:
  image:
    repository: public.ecr.aws/datadog/agent

clusterChecksRunner:
  image:
    repository: public.ecr.aws/datadog/agent

To set the Agent to a specific version, set agents.image.tag and clusterChecksRunner.image.tag. All image tags starting with 7.* embed the Python 3 runtime.

agent:
  image:
    tag: 7.34.0

clusterChecksRunner:
  image:
    tag: 7.34.0

You can use both options at the same time.

agent:
  image:
    repository: public.ecr.aws/datadog/agent
    tag: 7.34.0

clusterChecksRunner:
  image:
    repository: public.ecr.aws/datadog/agent
    tag: 7.34.0

By default, the Datadog Operator uses an agent:7.*.* image that embeds the Python 3 runtime.

If the image information is not specified in the DatadogAgent resource, the Operator deploys a Python 3 Datadog Agent image.

If you have previously pinned the image version:

apiVersion: datadoghq.com/v2alpha1
metadata:
  name: datadog
spec:
  override:
    clusterChecksRunner:
      image:
        tag: 6.33.0
    nodeAgent:
      image:
        tag: 6.33.0

or you are using image.name:

apiVersion: datadoghq.com/v2alpha1
metadata:
  name: datadog
spec:
  global:
    credentials:
      apiKey: <DATADOG_API_KEY>
      appKey: <DATADOG_APP_KEY>
  override:
    # ...
    nodeAgent:
      image:
        name: gcr.io/datadoghq/agent:6.33.0
    # ...
    clusterChecksRunner:
      image:
        name: gcr.io/datadoghq/agent:6.33.0

Use the spec.global.registry if you need to change the default registry. The default is gcr.io/datadoghq/agent.

Then, pin the Agent 7 image tag in spec.override.nodeAgent.image.tag.

If you have enabled cluster check runners deployment, also pin the Agent 7 image tag in spec.override.clusterChecksRunner.image.tag.

apiVersion: datadoghq.com/v2alpha1
metadata:
  name: datadog
spec:
  # ...
  global:
    registry: public.ecr.aws/datadog
  override:
    # ...
    nodeAgent:
      image:
        tag: 7.33.0
    # ...
    clusterChecksRunner:
      image:
        tag: 7.33.0

Note: Datadog recommends that you do not set the *.image.tag. Instead, let the Datadog Operator keep the Agent image tag up-to-date with an Agent 7 image.

If you need to use an Agent JMX image, you can set it without specifying the Agent *.image.tag:

apiVersion: datadoghq.com/v2alpha1
metadata:
  name: datadog
spec:
  # ...
  global:
    registry: public.ecr.aws/datadog
  override:
    # ...
    nodeAgent:
      image:
        jmxEnabled: true
    clusterChecksRunner:
      image:
        jmxEnabled: true

In your DaemonSet manifest, update the image tag in each container definition:

• Each spec.template.spec.containers[*].image value
• Each spec.template.spec.initContainers[*].image value

For example, if your previous image value was gcr.io/datadoghq/agent:6.33.0, update it to gcr.io/datadoghq/agent:7.33.0.

Before:

apiVersion: apps/v1
spec:
  template:
    spec:
      containers:
      - name: agent
        image: gcr.io/datadoghq/agent:6.33.0
        # ...

After:

apiVersion: apps/v1
spec:
  template:
    spec:
      containers:
      - name: agent
        image: gcr.io/datadoghq/agent:7.33.0
        # ...

Use the extra_config field to set the python_version field to 3:

default_attributes(
   'datadog' => {
     'extra_config' => {
       'python_version' => '3'
     }
   }
 )

Use the agent_extra_config field to set the python_versionfield to 3:

class { "datadog_agent":
    agent_extra_options => {
        python_version => 3,
    },
}

Set the python_version to 3 inside of your datadog_config:

datadog_config:
  python_version: 3
