Performance Testing with Docker and OpenVPN

This guide provides the steps to run performance tests using Docker and OpenVPN.

Prerequisites

• Docker installed on your machine.
• OpenVPN configuration files available.

Running the Tests

Basic Test

Run the following command to execute a basic test:

docker run -e APP=Google -e FILE=googlebrowse -e STAGE_1_DUR=1m -e STAGE_1_VUS=3 ae1986694f40

Extended Test with VPN

Use this command to run an extended test with VPN:

docker run -e APP=Google -e FILE=googlebrowse -e STAGE_1_DUR=20m -e STAGE_1_VUS=1 -e VPN_USERNAME=freeopenvpn -e VPN_PASSWORD=180846206 --cap-add=NET_ADMIN -v /dev/net:/dev/net --network k6_bridge 08b45d28b828

OpenVPN Client

To start an OpenVPN client container, execute:

docker run -it --rm --cap-add=NET_ADMIN -v /dev/net:/dev/net -v /Users/prem/Desktop/premsvmm/PerformanceTestingK6/vpnbook-openvpn-fr200:/etc/openvpn openvpn-client

Running k6 with Custom Network

If you need to run k6 with a custom network configuration, use:

docker run --rm -it --network my_network your-k6-image [K6_OPTIONS]

Setting Up OpenVPN on Alpine Linux

1. Update the package index:

   apk update

2. Install OpenVPN:

   apk add openvpn

3. Copy the OpenVPN configuration file into the container:

   docker cp /Users/prem/Desktop/premsvmm/PerformanceTestingK6/vpnbook-openvpn-fr200/vpnbook-fr200-tcp80.ovpn d789d7ecd050:/app/

4. Start OpenVPN with the configuration file:

   sudo openvpn --config vpnbook-fr200-tcp80.ovpn
