A couple weeks ago I was faced with the challenge of installing Red Hat 3scale and configuring its tenants using solely the command line — no GUI allowed. This is a rather interesting use case, so I decided to write this article and show how to do it with just seven commands!
(By the way, I also decided to include Red Hat Single Sign-On (SSO) in the mix because I want my APIs to use OpenID Connect (OIDC) for authentication. But I’ll leave those commands to a future article.)

When I talk about desired outcomes or answer a question about where to get started with any part of a DevOps initiative, I like to mention NASCAR or Formula 1 racing. Crew chiefs for these race teams have a goal: finish in the best place possible with the resources available while overcoming the adversity thrown at you. If the team feels capable, the goal gets moved up a series of levels to holding a trophy at the end of the race.
To achieve their goals, race teams don’t think from start to finish; they flip the table to look at the race from the end goal to the beginning. They set a goal, a stretch goal, and then work backward from that goal to determine how to get there. Work is delegated to team members to push toward the objectives that will get the team to the desired outcome.

In this article, I demonstrate a systematic method to configure LDAP user and group synchronization in Red Hat OpenShift, as well as OpenShift role-based access control (RBAC) for these LDAP users and groups. Following these steps makes the management of your LDAP users and groups within OpenShift much easier. I achieve this goal by demonstrating:
- How to validate your
ldap parameters with
ldaptool prior to installing OpenShift.
- How to enable LDAP authentication in OpenShift for specific LDAP groups and organization units.
- The scripts and commands that let you synchronize members of your LDAP groups to OpenShift, which in turn lets you apply custom OpenShift RBAC rules on specific users or groups.

In the previous article of this series, Deploy your API from a Jenkins Pipeline, we discovered how the 3scale toolbox can help you deploy your API from a Jenkins Pipeline on Red Hat OpenShift/Kubernetes. In this article, we will improve the pipeline from the previous article to make it more robust, less verbose, and also offer more features by using the 3scale toolbox Jenkins Shared Library.

In a previous article, 5 principles for deploying your API from a CI/CD pipeline, we discovered the main steps required to deploy your API from a CI/CD pipeline and this can prove to be a tremendous amount of work. Hopefully, the latest release of Red Hat Integration greatly improved this situation by adding new capabilities to the 3scale CLI. In 3scale toolbox: Deploy an API from the CLI, we discovered how the 3scale toolbox strives to automate the delivery of APIs. In this article, we will discuss how the 3scale toolbox can help you deploy your API from a Jenkins pipeline on Red Hat OpenShift/Kubernetes.

Red Hat OpenShift 4.1 offers a developer preview of OpenShift Pipelines, which enable the creation of cloud-native, Kubernetes-style continuous integration and continuous delivery (CI/CD) pipelines based on the Tekton project. In a recent article on the Red Hat OpenShift blog, I provided an introduction to Tekton and pipeline concepts and described the benefits and features of OpenShift Pipelines.

Container-native development is primarily about consistency, flexibility, and scalability. Legacy Application Lifecycle Management (ALM) tooling often is not, leading to situations where it:
- Places artificial barriers on development speed, and therefore time to value,
- Creates single points of failure in the infrastructure, and
- Stifles innovation through inflexibility.
Ultimately, developers are expensive, but they are the domain experts in what they build. With development teams often being treated as product teams (who own the entire lifecycle and support of their applications), it becomes imperative that they control the end-to-end process on which they rely to deliver their applications into production. This means decentralizing both the ALM process and the tooling that supports that process. In this article, we’ll explore this approach and look at a couple of implementation scenarios.

Microservices architecture is taking over software development discussions everywhere. More and more companies are adapting to develop microservices as the core of their new systems. However, when going beyond the “microservices 101” googled tutorial, required services communications become more and more complex. Scalable, distributed systems, container-native microservices, and serverless functions benefit from decoupled communications to access other dependent services. Asynchronous (non-blocking) direct or brokered interaction is usually referred to as messaging.

In Part 5 this series, we looked into details that determine how your integration becomes the key to transforming your customer experience.
It started with laying out the process of how I’ve approached the use case by researching successful customer portfolio solutions as the basis for a generic architectural blueprint. Now it’s time to cover various blueprint details.
This article covers the final elements in the blueprint, storage services, which are fundamental to the generic architectural overview.
