Structured application logs in OpenShift

Logs are like gold dust. Taken alone they may not be worth much, but put together and worked by a skillful goldsmith they may become very valuable. OpenShift comes with The EFK stack: Elasticsearch, Fluentd, and Kibana. Applications running on OpenShift get their logs automatically aggregated to provide valuable information on their state and health during tests and in production.

The only requirement is that the application sends its logs to the standard output. OpenShift does the rest. Simple enough!

In this blog I am covering a few points that may help you with bringing your logs from raw material to a more valuable product.

Configuring Spring Boot on Kubernetes with Secrets

In the Part-I of the series, we saw how we used ConfigMaps in configuring spring boot application Kubernetes. ConfigMaps are OK when we use simple configuration data that do not contain sensitive information. When using sensitive data like API Keys, passwords etc. Secrets are the preferred and recommended way. In this second part of the series, we will explore configuring spring boot on kubernetes with Secrets.

The sources for this blog post are available in my github repo.

Configuring Spring Boot on Kubernetes with ConfigMap

ConfigMaps is the Kubernetes counterpart of the Spring Boot externalized configuration. ConfigMaps is a simple key/value store, which can store simple values to files. In this post  “Configuring Spring Boot on Kubernetes with ConfigMap”,  we will see how to use ConfigMaps to externalize the application configuration.

Configuring Spring Boot Application on Kubernetes

When the developers plan to deploy Spring Boot application on Kubernetes, the first question comes to a spring developer’s mind is “Can I use Spring Config server?” Spring Config server is a de-facto way of doing centralized configuration of a distributed application. Yes, we can use Spring Config server, but let’s think of some constraints that Spring Config server can have in a typical Enterprise deployment:

Easily secure your Spring Boot applications with Keycloak

What is Keycloak?

Although security is a crucial aspect of any application, its implementation can be difficult. Worse, it is often neglected, poorly implemented and intrusive in the code. But lately, security servers have appeared which allow for outsourcing and delegating all the authentication and authorization aspects. Of these servers, one of the most promising is Keycloak, open-source, flexible, and agnostic of any technology, it is easily deployable/adaptable in its own infrastructure.

Moreover, Keycloak is more than just an authentication server, it also provides a complete Identity Management system, user federation for third parties like LDAP and a lot more … Check it out on here.

The project can also be found on Github
