NIXus a docker powerered next generation application server kind.
Application servers are typically coupled to ecosystems like .NET platform or JavaEE. They are able to run just some kind of applications. In JavaEE, a server will run just JVM aplications deployed as WAR or EAR files.
Docker is a relatively new technology. It's an application container. It allows to run any contenerized application without having to install all the required runtime in the host machine.
NIXus is basically a group of microservices containers that run in choreography.
Basically it can run anything.
Install Docker Toolbox and configure docker.
Run the following command:
curl -L https://raw.githubusercontent.com/aitoroses/NIXus/master/install.sh | bash
Get NIXus running:
$ nixus start
Run a hello world container two times (cluster), and specify a NIXUS_{PORT}:
docker run -d -it -p :8000 -e NIXUS_8000=whoami-app jwilder/whoami
docker run -d -it -p :8000 -e NIXUS_8000=whoami-app jwilder/whoami
Try to do a CURL:
$ curl -L http://dev.docker/whoami-app
$ curl -L http://dev.docker:8000
Will return the container ID of the one that responds.
I'm c1b218dd8881
If you setup your DNS to resolve whoami.dev.docker you can also do
curl -L http://whoami-app.dev.docker
Thats all, your hello-world container is running with service discovery and clusterized.
NIXus registers when a new container has started/stoped and then it creates the correspoinding configuration files and stores the required container information.
The autodiscovery container magically is able to map a route to a container automatically.
For example, just by doing docker run -it -p :8000 -e NIXUS_8000=hello-app hello the hello image will run as a container and it's context will be hello-app.
The port tcp/8000 will be mapped to an arbitrary port in the host tcp/8000 -> tcp/31892.
NIXus will recognize that information and make the container discoverable through:
http://domain.com:8000http://domain.com/hello-apphttp://hello-app.domain.com
Other interesting property is that the proxy can replicate and load balance those containers across different hosts, so that each container is clusterizable on itself.
Like in the example above, we can just do:
docker run -d -it -p :8000 NIXUS_8000=hello-app hellodocker run -d -it -p :8000 NIXUS_8000=hello-app hellodocker run -d -it -p :8000 NIXUS_8000=hello-app hello
The same container will be spawned 3 times and NIXus will handle load balancing by default.
