Configuring the Upwind Sensor
To configure the Upwind Sensor according to your environment and security requirements, you can use the environment variables listed above. These variables allow you to specify essential configuration details, such as the Upwind API credentials, logging preferences, service limits, and more.
Setting Environment Variables
Before running the installation or configuration script for the Upwind Sensor, set the desired environment variables in your shell. Use the export command for each variable you wish to configure:
export VARIABLE_NAME="value"
Replace VARIABLE_NAME with the name of the variable you're setting, and "value" with the desired setting.
Installing the Upwind Sensor
After setting the environment variables, you can install the Upwind Sensor by executing the following command:
curl -s https://get.upwind.io/agent.sh | bash -s install
This command downloads and runs the installation script with the environment variables you've set, ensuring the sensor is configured as per your specifications.
Editing Configuration After Installation
If you need to edit the configuration after installation, you can modify the environment variables and re-run the configuration part of the script as follows:
curl -s https://get.upwind.io/agent.sh | bash -s configure
This command will re-apply the configuration changes based on the newly set environment variables.
By following these steps, you can ensure that your Upwind Sensor is customized to meet the specific needs of your infrastructure and security policies.
