RESTful JOptTourOptimizer in Docker

Containerizing an application helps to use it more conveniently across different platforms and, most importantly, as a microservice. Further, scaling an application becomes more straightforward as different standardized orchestration tools can be utilized. It can be launched either (locally) as part of a docker-compose or as a highly-scalable web-micro-service in a Kubernetes cluster, to give an example.

Setup JOptTourOptimizer-Docker

Setting up JOptTourOptimizer in your Docker environment only takes these three steps:

1) Pulling the image:

docker pull dnaevolutions/jopt_touroptimizer

2) Running a container:

docker run -d --rm \
    --name myJOptTourOptimizer \
    -e SPRING_PROFILES_ACTIVE="cors" \
    -p 8081:8081  \
    dnaevolutions/jopt_touroptimizer

Same command as a single line:

docker run -d --rm  --name myJOptTourOptimizer -e SPRING_PROFILES_ACTIVE="cors" -p 8081:8081  dnaevolutions/jopt_touroptimizer

Activating the profile "cors" will allow doing REST-calls from the same localhost from another application.

(If desired, please adjust docker run argument to your needs)
