The certificate generation is based on work by Lars Karlitski in our osbuild
CA. The server and client certs now contains Subject Alternative Name making
Python's request module and Go 1.15 happy (they deprecated certificates
without SAN).
Several reasons why we want to switch to the certificate generation:
1) The pre-generated certificates are not documented. If someone wants
to inspect them, he must know the right openssl incantation. This way,
you are able to see what's inside the certificates in a plain text.
2) The pre-generated certificates are going to expire at one point and
someone will be surprised.
3) Shipping private keys in RPMs is iffy. I know, it's just for testing but
still...
4) Auth tests are generating their own certificates. To achieve consistency,
we have two options:
a) Ship also all certificates for auth tests. That's extra 8 ones or
something like that.
b) Generate all certificates on fly. This commit does that.
5) The setup introduced by this commit is very similar to the one in our CA
making the test environment very similar to what's running in production.
tl;dr: I think this is a good step forward.
The test package should be self-contained and contain all the configuration
necessary for a known-good test run (minus secrets). This moves repo
overrides from the test orchestration into the test package.
We want all the external sources (including boot isos and repositories) to
be pinned by their content hash, and never use anything that is not strictly
defined. This moves us in the right direction, but we still have some tests
to update to use these shipped repos rather than official mirrors.
One remaining challenge is that we must make sure all our test runners have
access to the RHEL snapshots, which is not currently the case for the runners
in EC2, but a solution is in the works.
