docker compose를 이용해서 r-shiny app을 구동하는 proxy 서버를 띄우는 작업을 해야하는데 r로 이런걸 하는건 처음이라 좀 오래 걸렸다. 반나절을 다 써버렸네... 시간 아깝구로.. 그리고 공식 홈페이지 설명은 개떡같다. 도커고 도커 컴포즈고 네트워크고 잘 모르는 사람이 했다면 시간 엄청 잡아먹었을듯... 역시 프레임워크 선정은 사람이 많이 쓰는걸 해야 에러 잡기가 쉽다. 레퍼런스가 많으니... 아무튼 감사의 의미와 잊지 않겠다는 의미로 아래에 해당 내용을 정리한 것을 붙여넣었다.

Docker uses networks to enable communication between containers. For ShinyProxy to communicate properly with the Shiny App, the network specified in docker-compose.yml must be the same as the same as that listed in application.yml. (Tip, if you’re using a docker-compose file to launch the app, don’t set up the docker network manually, see here for why).
Each container listed in services: is named in container_name, with the Dockerfile being pointed to via. the context and Dockerfile variables. If the container was terminated with an error code, the restart line instructs Docker what action is to be taken . The networks variables lists the Docker network that the container has access to.
The network used by all applications in this docker-compose must match the network specified in the ShinyProxy application.yml.
Building and running
# Go into your project folder
cd shinyproxy-config/docker-compose-example
# Build all docker images
docker-compose build
# Run shinyproxy
docker-compose up -d shinyproxy
Visit: http://localhost:8080
To stop shinyproxy use docker-compose down.
