This error may occur when using extundelete with -o:

extundelete: No such file or directory while creating directory

The problem is that -o expects a relative path to the current directory (not an absolute path). Either use -o with a relative path or remove -o.

Reference: https://help.ubuntu.com/community/Oracle%20Instant%20Client

Tested on: Ubuntu 18.04, 20.04

Decide which version of the Oracle client to install
- Each version of the client supports certain versions of the database; for example, Oracle client 12.1 supports Oracle database 10.2 - 19c
- See here for more information: http://support.oracle.com/epmos/faces/DocumentDisplay?id=207303.1
Download the Oracle client packages
- Go here and download the desired RPM package(s): https://www.oracle.com/database/technologies/instant-client/downloads.html

Change apiVersion from:
```
- apiVersion: v1
```
(or apiVersion: apps.openshift.io/v1)

to:

Why

Unlike Docker, buildah doesn't need root privileges to run
Buildah can pass yum entitlements from build container to container being built
- Since this has to be done manually (see /run/secrets:/run/secrets below) couldn't Docker do this as well?

Steps

Make sure you're using a RHEL host registered with yum
Make sure you're using RHEL build container image, such as:

Problems

Application logs are mixed with kubernetes logs. They can be searched using a query similar to this one, but it's a bit unwieldy as it's not using Graylog fields (for example, the quotes can't be left out): "container_name=mycontainer"

The actual log message is prefixed with a bunch of extra information that makes the logs difficult to read in the Graylog UI. For example, the message in Graylog shows up as:

app1.openshift.example.org output_tag: namespace_name=mynamespace, container_name=myapplication, pod_name=myapplication-7dd79c7bb7-qkfzk, message=Web server listening at: http://0.0.0.0:3000

But the actual log message is:

Overall impression

Splunk—the de-facto standard—is a much better product overall and requires less tweaking to get things working. If you can work with the limitations of Splunk Free (500 MB daily limit, no authentication/RBAC, no alerts, no clustering, etc), use it.

Otherwise, Graylog is a decent product and works well, but will require some tweaking.
