# 2 Docker container

## 2.1 Build container locally

The `Dockerfile` is included with the package in `inst/docker` folder.

Here is the current content of `Dockerfile`:

You can simply build it locally, enter folder which contain that `Dockerfile`, in this case, it is under `inst/docker/sevenbridges`

    docker build -t sevenbridges/sevenbridges-r .

## 2.2 Pull from Docker Hub

A hook is added to build the Docker image automatically from the sevenbridges-r GitHub repository. It is automatically built on Docker Hub. You can directly use this image `sevenbridges/sevenbridges-r`. Everytime a push is made in the GitHub repo, the Docker container is re-built.

# 3 Launch RStudio Server from Docker container

For example, you can ssh into your AWS instance, here I suppose you already have Docker installed, and pull the image

    docker pull sevenbridges/sevenbridges-r

To launch sevenbridges RStudio Server image, I recommend you read this tutorial

Or following the quick instruction here

    docker run -d -p 8787:8787 sevenbridges/sevenbridges-r
    docker run -d -p 8787:8787 -e USER=<username> -e PASSWORD=<password> rocker/rstudio

You will be able to access the RStudio in the browser by something like

`http://<your_ip_address>:8787`

Sometimes you want to add more users, to add users

    ## Enter the container
    docker exec -it <container-id> bash
    ## Interactively input password and everything else
    adduser <username>

## 3.1 Launch both RStudio Server and Shiny Server from the same Docker container

Sometimes it is very conventient to launch both RStudio Server and Shiny Server from a singel container and your users can manage to using RStudio Server and publish Shiny apps at the same time in the same container. To do so, just pull the same image and launch them at different port.

    docker run  -d -p 8787:8787 -p 3838:3838 --name rstudio_shiny_server sevenbridges/sevenbridges-r

To mount file system you need to use `--privileged` with fuse.

    docker run  --privileged -d -p 8787:8787 -p 3838:3838 --name rstudio_shiny_server sevenbridges/sevenbridges-r

check out the ip from docker machine if you are on mac os.

    docker-machine ip default

In your browser, `http://<url>:8787/` for RStudio Server, for example, if 192.168.99.100 is what returned, visit `http://192.168.99.100:8787/` for RStudio Server.

For Shiny Server, per user app is hosted `http://<url>:3838/users/<username of rstudio>/<app_dir>`, for example, for user `rstudio` (a default user) and an app called `01_hello`, it will be `http://<url>:3838/users/rstudio/01_hello/`. To develop your Shiny app from RStudio Server, you can log into your RStudio Server with your username, and create a fold at home folder called `~/ShinyApps` and develop Shiny apps under that folder, for example, you can create an app called `02_text` at `~/ShinyApps/02_text/`.

Let’s try this, please log into your RStudio at `http://<url>:8787` now, then try to copy some example over to your home folder under `~/ShinyApps/`

    dir.create("~/ShinyApps")
    file.copy("/usr/local/lib/R/site-library/shiny/examples/01_hello/",
              "~/ShinyApps/", recursive = TRUE)

If you logged in with the username `rstudio`, then visit `http://192.168.99.100:3838/rstudio/01_hello` you should be able to see the hello example.

Note: Generic Shiny apps can also be hosted `http://<url>:3838/` or for particular app, `http://<url>:3838/<app_dir>` and inside the Docker container, it is hosted under `/srv/shiny-server/`.
