Community Infrastructure Maintainer for ELK Services


The OpenStack community is seeking developers and system administrators with a background in maintaining Unix/Linux servers and free software to join the Infrastructure team (TaCT SIG now). This team is responsible for designing, building and maintaining the systems that are used in the day to day operation of the OpenStack project as a whole.

There is a critical need for infrastructure team members for maintaining Logstash, Elasticsearch, Elastic-recheck services. These services (collectively called ELK) + elastic-recheck service which automate the identification of most critical failures. These services are used by upstream community development in day to day software development and testing. This helps the community to deliver the stable code. To know more details about the criticality of these services in upstream development please refer to this ML thread

Business Case

Sponsorship of a team member is a way to visibly help build and maintain the development, collaboration, and testing tools used by the third most active open source project in the world without having to donate hardware. Team members interact with contributors across all the OpenStack projects as well as with the OpenStack service providers who supply resources for OpenStack CI systems.

Sponsors of infrastructure team members have a “seat at the table” as decisions are made about how to improve and scale OpenStack infrastructure going forwards.

Sponsors gain in-house expertise and experience building large-scale, adaptive software development infrastructure with open-source tools and public configuration management. There is no better way to gain exposure to, and expertise with, leading-edge CI/CD in advance of potential deployment at home, than to place someone on the team deploying one of the world’s most scaled out instances of the Zuul project.

The software developed, skills involved, and open community practices learned can have high value downstream in a sponsor’s own enterprises and software products.

Technical Details

The OpenStack community team pushes a lot of code changes and to test it thoroughly, each code change runs a lot of jobs in CI in an integrated way with a different set of configurations. All of the tests make sure that OpenStack as a whole stack works and is stable software when delivered at the end. This complete process involves a lot of tooling and their maintenance.

The infrastructure team is responsible for designing, building and maintaining the systems that are used in the day to day operation of the OpenStack project as a whole; this includes development, testing, and collaboration tools. All of the software it runs is open source, and under public configuration management so that everyone in the community has the opportunity to participate. One very effective way to get involved in OpenStack and gain a deep understanding and visibility within the community is by helping operate this infrastructure.

A few of the tools which are critical for day to day upstream development are Logstash, Elasticsearch, Kibana (ELK as short) and Elastic-recheck and because there is no maintainer, they are being proposed for retirement.

In particular, the team seeks developers and systems administrators with a background both in maintaining Unix/Linux servers and free software, to maintain the ELK services. Everything possible goes through code review, and gets extensively documented and communicated with the rest of the community over IRC and mailing lists. Server resources are donated by companies operating OpenStack services so there is substantial opportunity both for people who have experience in those technologies as well as anyone wishing to gain more familiarity with them.


The infrastructure team leverages resources donated from companies operating OpenStack services. The community uses the software it produces as a tool for testing it. Every day, contributors submit thousands of patches for review. Infrastructure tools deploy each patch and test it against thousands of tests and scenarios. This volume provides an opportunity to improve the software we write by giving us first-hand experience with issues at scale. The benefit of fixing these issues for the OpenStack CI system is two-fold:

  1. It makes the test platform more stable and robust

  2. Products or services benefit from the fixes being applied upstream

Don’t Repeat Yourself or Your Testing (DRY)

The culture built around extensive testing in OpenStack makes it easier for us to trust patches proposed for review. We’ve integrated this culture into our review process. Duplicating a social and technical CI system of this size takes incredible amounts of time, people, and patience. Bolstering the CI system we already have in place allows you to focus on testing that is specific to your product or service.

Immediate Feedback

The OpenStack CI system is the backbone of feedback for contributors and operators. Users get this feedback early, ideally before the patch lands. Ensuring early feedback through a robust CI system and testing means fewer surprises down the road when you attempt to integrate your product into a new release or deploy a new version of a service. Without the ELK services, it will be very difficult to debug a failure and to deliver the stable code.
