Now for the gory details.

Files

The basic files required for a product-only webservice (no UI) are the following:

├── Makefile
├── NEWS.md
├── README.md
├── README_THIS_IS_GIT_BRANCH_master
├── docker
│   ├── docker-compose-desktop.yml
│   ├── docker-compose-test.yml
│   └── docker-compose-v1.yml

└── plot-service
    ├── Dockerfile-test
    ├── Dockerfile-v1
    └── R
        ├── plot-service-app.R
        ├── server-load
        │   ├── createDataList.R
        │   ├── createInfoList.R
        │   ├── createProduct.R
        │   ├── createTextList_en.R
        │   └── createTextList_es.R
        └── sharedUtils
            └── createAPIList.R

A single server-load sub-service is defined with all relevant R scripts located in plot-service/R/server-load/.

Running the app from RStudio

Inside RStudio you can run the app with:

• cd plot-service/
• "Files > More > Set As Working Directory"
• open up R/plot-service-app.R
• set breakpoints if desired
• click the 'Source' button

The app will be available at:

localhost:8080/plot-service/test/

Running the app with Docker

You can create and run a docker image with the app by:

• typing make desktop_reboot

The app will be available at:

localhost:8080/plot-service/test/

The Makefile has targets for three different types of deployment: desktop, test, operational.

A quick refresher on docker commands is available at the docker cheatsheet.

Host Computer Settings

Log Files

Log files will be written to a directory named after the deployment type:

/var/log/plot-service/test/app or /var/log/plot-service/operational/app

except for desktop which are written to:

plot-service/logs

ProxyPass Settings

On AWS instances, ProxyPass settings are defined in:

/etc/apache2/sites-enabled/default-ssl.conf

Testing the app

You can ask to see the api by hitting the service with no sub-service specified:

http://localhost:8080/plot-service/test

You can ask for a plot:

http://localhost:8080/plot-service/test/server-load?serverid=joule.mazamascience.com
