# Install the Go agent without the Contrast Service

### Important

If you did not opt-in to install the Go agent without the service, then follow the install the Go agent (legacy) instructions.

You can opt-in to configure the agent to report directly to Contrast by installing the Go agent without the Contrast service.

The executable must be built using contrast-go to instrument the application with the agent. A basic installation of the Go agent consists of two parts: producing an executable and running the executable. An installation overview looks like this:

• Go agent

• contrast_security.yaml

Ensure your yaml or environment variables are set to bypass:true.

agent:
service:
bypass: true

Alternatively, the same feature can be enabled using environment variables:

CONTRAST__AGENT__SERVICE__BYPASS=true
2. Set up appropriate permissions.

3. Build the Go application, replacing go with contrast-go to get a final application artifact which contains the Go agent.

4. Run the executable.

5. Exercise and test your application.

6. Verify that Contrast sees your application.
