Description Jan Zmeskal 2020-01-23 09:25:30 UTC

Description of problem:
If you don't specify "ovirt_insecure: true" in your oVirt credentials config, the installation will eventually fail apparently because machine-controller container (and maybe some others as well) does not trust engine's CA. Even though the CA is trusted by the bastion's operating system.

Version-Release number of the following components:
./openshift-install version
./openshift-install unreleased-master-2320-g6791d02a6fadedd44f9263fb72f9f65dbd51bfe0-dirty
built from commit 6791d02a6fadedd44f9263fb72f9f65dbd51bfe0
release image registry.svc.ci.openshift.org/ovirt/ovirt-release@sha256:c46483c4bfd9418226d3bbf46e15b7905dfefcccfe899b652db3a8c88b522b96

How reproducible:
I tried it only once but I believe this behaviour is consistent.

Steps to Reproduce:
1. Make sure your bastion machine (the one from where you conduct the installation) trusts your engine's CA. If your engine is your bastion, then it's easy as running this:
ln -sf /etc/pki/ovirt-engine/ca.pem /etc/pki/ca-trust/source/anchors/ && update-ca-trust

2. Now just follow the installation steps with one specific. When you're setting up your ovirt credentials file, completely omit the line that says "ovirt_insecure: true". It should default to false. Mine looks like this:
cat ~/.ovirt/ovirt-config.yaml
ovirt_url: https://<engine_fqdn>/ovirt-engine/api
ovirt_username: admin@internal
ovirt_password: <pass>

3. Try to install OCP4 and monitor the progress.

Actual results:
The installation got pretty far and most of the cluster operators came up, not all though: http://pastebin.test.redhat.com/828699
Also workers nodes were not created.

Expected results:
The installation is finished successfully.

Comment 4 Jan Zmeskal 2020-03-19 13:27:59 UTC

Verified with openshift-install-linux-4.5.0-0.nightly-2020-03-19-042419

Verification steps:
1. Create /root/.ovirt/ovirt-config.yaml with following content:

ovirt_url: https://<engine_fqdn>/ovirt-engine/api
ovirt_username: admin@internal
ovirt_password: "<pass>"
ovirt_ca_bundle: |-
  -----BEGIN CERTIFICATE-----
<CA gibberish>
  -----END CERTIFICATE-----

2. Prepare valid install-config.yaml and copy it to install-dir
3. Run openshift-install create cluster --dir=install-dir
