Yandex-Tank TLS requests with phantom

Question

How can I setup yandex-tank to tell phantom to use TLS encryption instead of SSL? I already found that phantom can be configured to used TLS via it's startup parameter --ssl-protocol=tlsv1, but I don't know how can I pass this parameter when using yndex-tank configs.

Here is the part of load.ini file which is configuring phantom load generator.

[phantom]
address=%(env_url)s:443
ssl=1
writelog=1
rps_schedule=step(1, 70, 5, 15s) line(1, 70, 1m)
header_http=1.1
uris=/

I'm trying to test Google Cloud Functions directly just to confirm breaks in connection, and as it turned out, GCF using TLS encryption. I tested this with curl, so now I need to configure it somehow using tank.

Answer 1

1) Correct link to load generator - https://github.com/yandex-load/phantom, which uses openssl library.

2) Checked openssl's SSLv23_client_method which is used in phantom code

These are the general-purpose version-flexible SSL/TLS methods. The actual protocol version used will be negotiated to the highest version mutually supported by the client and the server.

So, just make sure that target's webserver and openssl on load server both support TLS.

3) Option ssl=1 just says to phantom "use tls encryption" and doesn't specify proto version
