System Environment Variables in amazon-cloudwatch-agent.json?

[shihborl]

Hi All,

I just wanted to check with the community about using env variables in this json file.

Is doing something like this supported?

{
  "logs": {
    "credentials": {
      "role_arn": "arn:aws:iam::${MONITORING_ACCOUNT}:role/CrossAccountMonitoringAgentRole"
    },
    "log_stream_....

The expectation is for the agent to be able to fill MONITORING_ACCOUNT with the defined value in env and publish to that account using this role.

MONITORING_ACCOUNT=1234567890
