[IMPORTANT - test issue #99] Issues with installing when running behind a web proxy


More about proxies:

Here is update on the Lava proxy business. Please, read this very
carefully, since this is the solution to the problems with Lava
proxies, as well as Lava DUT ones.

YES, after applying what Remi advised to me, the qemu01 test:

worked like a charm. I simply copied /etc/lava-server/env.yaml to
/etc/lava-server/env.dut.yaml (and created the new file).

Remi, I would like to thank you for the advise!

Best Regards,
Zoran Stojsavljevic

Not exactly.

1/ The process that is deploying, booting and testing a DUT (Device
Under test) is called lava-run.
lava-run environment variables are controlled by /etc/lava-server/env.yaml

By default, all environment variables are removed and only a small set
of variables are added.
This helps to make executions reproducible between dispatchers and instances.

So if you need an environment variable to be set, then you have to add
it to /etc/lava-server/env.yaml

2/ On the DUT itself, by default, we don't add or change any
environment variable. Because that's the user responsibility.
However, if /etc/lava-server/env.dut.yaml does exists, it will be used
to add environment variables to the DUT shell.
To create the list of environment variables to add to the DUT, we take
the full environment from lava-run (as defined by
/etc/lava-server/env.yaml) and we apply the rules from env.dut.yaml.

I hope that does help you to understand how environment is setup in lava.

At the end of test issue #99, I added the solution to this problem.

Lava does NOT read VM's ENV variables. It ignores them. Lava reads
/etc/lava-server/env.yaml as setup proxy file!

Included there also /etc/lava-server/env.yaml file example.

It could be done also DIRECTLY (every time bringing up the VM) using
python, tapping into the urllib3 python code (example given):

I've tried this, using in-line python interpreter, it worked.
