Dockerized XNAT

Use this repository to quickly deploy an XNAT instance on docker.

Introduction

This repository contains files to bootstrap XNAT deployment. The build creates five containers:

docker
docker-compose (Which is installed along with docker if you download it from their site)

Start the system

 $ cd containerized-xnat
 $ docker-compose up -d

 wget --quiet --no-cookies https://bintray.com/nrgxnat/applications/download_file?file_path=xnat-web-1.7.4.war -O webapps/xnat.war

Your XNAT will soon be available at http://localhost/xnat.

Get a shell in a running container:

To list all containers and to get container id run

docker ps

To get into a running container
```
`docker exec -it <container ID> bash`
```
Read Tomcat logs:

docker exec -it <container id for xnatdocker_xnat-web_1 > tail -f /opt/tomcat/logs/catalina.2017-07-28.log
Bring all the instances down by running

docker-compose down --rmi all (this will bring down all container and remove all the images)
Bring XNAT instance up again

docker-compose up -d

Browse to http://localhost:9090/graph

To view a graph of total cpu usage for each container (nginx/tomcat/postgres.cAdvisor/Prometheus) execute the following query in the query box container_cpu_usage_seconds_total{container_label_com_docker_compose_project="xnatdocker"}
Browse to http://localhost:8082/docker/
