However the principals can apply to any distributed system.Īs a long time vagrant user, I'm used to building vagrant infrastructure using this workflow. Apache Spark is a distributed Big Data processing framework with a master/slave architecture (you need one master, and at least one slave). lets play around with some different ways to create a docker container that runs Apache Spark. These services are small, highly decoupled and focus on doing a small task."

"In computing, microservices is a software architecture design pattern, in which complex applications are composed of small, independent processes communicating with each other using language-agnostic APIs. The reason this is important is that the definition of a microservice is quite vague, and in my opinion, it allows for quite a few anti-patterns, like ssh provisioning. However, by implementing this anti-pattern, we can better appreciate the microservices design pattern, in the way that it really properly implemented. the mutable nature of the VMs leads to many things which can go wrong, and also to systems which might be poorly documented, with multipurpose functionality that isn't composable, or easily load balanced.

This is a common design pattern for typical cloud based infrastructures and testing, and it is extremely flexible and easy to hack around with - but a its also an anti-pattern. In the first attempt, we will create some simple containers, and use SSH to get into them, so that we can start some services. This intimate connection will be realized in this post by building some dockerized spark containers (first, the wrong way), and then rebuilding them as proper standalone microservices.

I hope that, by the end of this post, a light bulb will go off in your head, and you to will see the connection between immutable infrastructure, idiomatically designed microservices, and portable testing of distributed applications (in this case, we will use vagrant, but you can use any orchestration framework you want to test a microservice, thanks to its self-sufficient and easily composable nature - even a shell script).

In any case, I have tried to keep the code snippets to the point so that this post can be read in isolation. If you are on a non linux system, you can install VMWare/VirtualBox and have vagrant launch the containers for you in a VM of your choice which is docker friendly. To leverage the snippets here, you will need Docker and Vagrant installed. And, even if you don't fully buy into the microservices ecosystem in its current state, building clean and simple containers which do one thing perfectly is probably never a mistake.įor those wondering how you can use vagrant in the post VM universe which we are now living in, this post should also be helpful.
#Centos install apache spark how to
There are many ways to containerize an application, but currently the microservices movement, which is becoming a more popular idiom for using docker, provides a lot of benefits which cannot be realized on just "any" Dockerfile.Additionally, for folks interested in spark, we will demonstrate how to orchestrate and test a spark microservices cluster using Docker on Centos. In this post, I'll walk through two different ways to containerize an application. To really grok these connections, you need to build a distributed system with containers from scratch. this paves the way for a new paradigm in load balancing, high availability, and dynamic resource sharing.Įnough high level stuff. Immutable services can, by definition, be deployed without any heavy weight installers or configuration management. One of the most exciting things about containers, is that they (if designed properly) can embrace the immutability principle, which is a fundamental concept behind many increasingly popular functional programming languages (which gave rise to frameworks such as Spark and MapReduce), and highly reliable software systems which are easy to parallelize operations on top of. Rather than serving as lightweight VMs, we are seeing that the common practice for containerization of an application is evolving in lock step with the microservices movement, which is quite different from the pre-container world view of scalable systems (which involved, typically, mutable services on VMs and heavy-weight provisioning).

but in some ways, this can be a bit of an anti-pattern. For example, for beginners, you can build a container as a "lightweight VM". There are a few different ways to build a container. Note: This post is done using centos7 as a base for the containers, but these same recipes will apply with RHEL and Fedora base images. Today we'll talk about the idioms we can use for containerization, and specifically play with apache spark and cassandra in our use case for creating easily deployed, immutable microservices. Containerizing things is particularly popular these days.
