I'm trying do this simple command but it keeps failing:

 echo "secret_backend_command: /home/ec2-user/dd-get-secrets.py" >> /etc/datadog-agent/datadog.yaml"

I tried all the following:

        - [ sh, -c, echo "secret_backend_command: /home/ec2-user/dd-get-secrets.py" >> /etc/datadog-agent/datadog.yaml ]

        - 'sh -c "echo \"secret_backend_command: /home/ec2-user/dd-get-secrets.py\" >> /etc/datadog-agent/datadog.yaml"'

        - sh -c "echo 'secret_backend_command: /home/ec2-user/dd-get-secrets.py' >> /etc/datadog-agent/datadog.yaml

any idea how to fix this quotes ?

note I tested with another file rather than datadpg.yaml because I'm getting Permission denied for this one.

examples I found in here didn't work

I changed the way of doing it and instead of having it in the yaml list in runcmds, I created a script and instead put this command inside and call the script in the runcmds. By doing so, I got rid of the tricky handling of ":" and quotes in cloud-init. 

  UserData:
    'Fn::Base64': !Sub |
      #cloud-config
      write_files:
        - path: /home/ec2-user/update-datadog-config.sh
          permissions: 0744
          owner: root
          content: |
            #!/usr/bin/env bash
            set -e
            echo "secret_backend_command: /home/ec2-user/dd-get-secrets.py" >> /etc/datadog-agent/datadog.yaml
      runcmd:
        - bash /home/ec2-user/update-datadog-config.sh
