Install Apache SOLR 4.9.0 in one command using Docker

Hey! Just a quick post to mention my new container for Apache SOLR 4.9.0. Use: docker run -d -p 127.0.0.1:2222:22 -p IP_ADDRESS:8080:8080 -t -i tehes/solr-4.9.0 This will pull the solr-4.9.0 image from my public repository, build and run the containers. Just replace IP_ADDRESS with your server's external ip address for example. The port 2222 of the host will be redirected to the port 22 of the container. The port 8080 of the host will be redirected to the port 8080 of the container. Access your container: http://IP_ADDRESS:8080 http://IP_ADDRESS:8080/solr ssh [email protected] -p 2222 (password = password // SSH only allowed from the host) Docker repository : https://registry.hub.docker.com/u/tehes/solr-4.9.0/ ...

Docker is an open platform for developers and sysadmins to build, ship, and run distributed applications, whether on laptops, data center VMs, or the cloud. With docker, you can setup and run a fully isolated environment with just one command, and this environment will be able to run on any platform where Docker runs. It's trully amazing how fast you can now deploy environments. The installation is pretty easy on Ubuntu but can be a little bit tricky on Debian 7.
