Tests

  • copy tests/load.yaml from tests/load.yaml.example and replace $SERVER and $PORT variables in tests/load.yaml

  • copy tests/monitoring.xml from tests/monitoring.xml.example and replace $SERVER and $USERNAME variables in tests/monitoring.xml

  • get token from https://overload.yandex.net and put it to file tests/overload_token.txt

  • put ssh public key to target server

  • run yandex-tank:

cd tests && docker run -v $(pwd):/var/loadtest -v $HOME/.ssh:/root/.ssh --net host -it direvius/yandex-tank
