Bug 1417525 - Using openshift_hosted_logging_deploy=true fails on repeated runs

Doc Type: Bug Fix
Doc Text:
Cause: Rerunning the installation playbook with 'openshift_hosted_logging_deploy=true' would redeploy the logging deployer pod using the install mode and would fail because logging was already installed. Consequence: The ansible playbook fails due to waiting on the deployer pod to complete successfully. Fix: With 3.5 we no longer use the logging deployer pod to install logging but rather the openshift_logging role. It is able to handle previously installed logging. Result: The playbook will complete successfully

Description Peter Larsen 2017-01-30 05:27:21 UTC
Description of problem:
When setting openshift_hosted_logging_deploy=true on a deployment, re-running the config.yaml playbook will fail the deployment as existing objects are found which blocks the deployer from running. As a result, ansible times out and errors out. 

Version-Release number of selected component (if applicable):

3.4 - pretty sure this applies to prior versions too. 

Steps to Reproduce:
1. Do default install with openshift_hosted_logging_deploy=true
2. After successful run where logging was attempted, re-run the install with the same configuration parameters.

Actual results:
Install failure

Expected results:
Logging configuration wiped out, replaced/reinstalled from scratch.

Can you provide the errors that are seen? Can you also please attach the logs from the Deployer pod?

It's the same error you get when you attempt to run the logging deployer after having run the deployer before. It errors out saying templates already exist, or service accounts already exists etc. Depending on where in the process it was. There are options on the deployer template to "redeploy" and avoid these kinds of errors - I don't know if that is the right strategy for the ansible installer though.

Comment 4 ewolinet 2017-01-30 20:38:27 UTC
Yeah, I'm not sure if using the 'redeploy' mode is the correct approach to avoid those errors... 

As stated above, with the rewrite for 3.5 we no longer rely on the deployer pod, so we should better handle cases where objects already exist without needing to remove and then reinstall.

Tested logging 3.5.0 deployment with the latest codes from https://github.com/openshift/openshift-ansible -b master, re-run playbooks succeeded, did not encounter error. Logging can be deployed successfully. Set to verified.
