There are cases where the kubeconfig can be read only like when running
Kraken as a kubernetes deployment. This commit fixes the instances to
use -n flag instead of a namespace context switch.
This commit:
- Adds timeout to avoid operations hanging for long durations.
- Improves exception handling and exits wherever needed.
- Sets KUBECONFIG env var globoally to access the cluster.
This commit modifies the wait time from 60 seconds to 3 seconds between
each of the requests to the API to capture the components state at a more
granular level by default.
This commit:
- Adds support to automate the infrastructure pieces leveraged by Kraken
including Cerberus and Elasticsearch
- Adds a Kraken config that can be used to discover all the infra pieces
automatically without having to tweak the configuration.
* Support for baremtal node scenarious
* Finished baremetal support
* Added documentation for baremetal
* Clarify limitations of implementation in documentation
* Add baremetal support to new run.py file
* Allow use on newer machines
Some older machines require lanplus instead of lan
* Setup to allow per-device user, pass, and bmc address
Also set min version for a dependency
* Fix linting issues
* More linting issue fixes
* More linter issues
* Account for linter standard non-conformity
* Added baremetal warning

This commit enables alerting in Kraken based on the Prometheus queries defined
by the user and modifies the return code of the run to determine pass/fail for
the run.
This commit:
- Enables Kraken to leverage kube-burner to scrape metrics from
Prometheus and index them into Elasticsearch. This way we can
take a look at the metrics in Grafana long term even after the
cluster is terminated.
- Enables separation of operations based on distribution with
OpenShift as the default option. One of the use cases is to
capture Prometheus instance details as it's installed by default
while it's optional for Kubernetes.
This commit:
- Refactors the code base to be more modular by moving functions
into respective modules to make it lean and reusable.
- Uses black to reformat the code to follow PEP 8 practices.
This commit:
- Adds a pointer to a new blog which emphasizes the importance
of making chaos part of Perf/Scale test runs.
- Bumps up the allowed max-line-length for the linters.
This commit enables performance monitoring on the cluster when
running Kraken to be able to observe how cluster reacts to failures
as it's important to make sure the cluster is healthy in terms of
both recovery as well as performance.
