 This post is about some of the struggles I’ve had while dealing with configuring HTTP(s) proxy for docker daemon process. I note it here for myself as well as others who might run into this issue in future. People familiar with Docker will know that it has a process (called docker daemon) which is responsible for handling requests from a ...

Container Orchestration | Definition, Benefits & How It Works In the 1970’s, the concept of a container-based application emerged to transform the IT world. For the first time, the software was deployed consistently and reliably regardless of the target environment’s changes (private or public cloud, personal computer, etc.). With the development of containers, container orchestration has become a trending topic ...

Part of our everyday ci/cd tasks involve using containers in order for the tests to take effect.So what if you could control the containers you use through your tests and serve your scenarios better.Also what if you could do this in a more managed way? Testcontainers is a Java library that supports JUnit tests, providing lightweight, throwaway instances of common ...

In an earlier video, I shared how to run the Quarkus remote-dev mode in Docker containers, which is very helpful for local and remote development environments. Since Quarkus version 1.6, however, the way how we execute the remote dev mode has changed. Assuming, we’d like to have the same setup like in the mentioned video. What’s new is that we ...

Previously we created successfully a Zookeeper ensemble, now it’s time to add some Kafka brokers that will connect to the ensemble and we shall execute some commands. We will pick up from the same docker compose file we compiled previously. First let’s jump on the configuration that a Kafka broker needs. 01 02 03 04 05 06 07 08 09 ...

What are we going to do… I am going to install docker and docker-compose on a centos 8 host and I am going to deploy a docker container that will ...

Previously we spun up Zookeeper and Kafka locally but also through Docker. What comes next is spinning up more than just one Kafka and Zookeeper node and create a 3 node cluster. To achieve this the easy way locally docker-compose will be used. Instead of spinning up various instances on the cloud or running various Java processes and altering configs, ...

Kafka popularity increases every day more and more as it takes over the streaming world. It is already provided out of the box on cloud providers like AWS, Azure and IBM Cloud. Eventually for cases of local development it is a bit peculiar due to requiring various moving parts. This blog will focus on making it easy for a developer ...

In this second part of docker tutorial, I’ll explain basics of networking in docker with stand-alone containers. Remember from the previous part of the tutorial where we mapped port of our host machine and the container? In this part, we will setup our containers so they can communicate with each other and for that we don’t need to do an ...
