BIND MOUNT INSIDE CONTAINER

docker run -v /path/on/host:/data busybox ls /data

Equivalent way but managed with "docker volume" - This do not work with file, only with directory

docker volume create --opt type=none --opt device=/path/on/host --opt o=bind my_vol
docker run -v my_vol:/data busybox ls /data

The user lauching alpine docker image is member of docker group. As he does not need sudo to use docker

sudo ls -al /root
drwx------  3 root root 4096 aoÃ»t   9  2015 .
drwxr-xr-x 25 root root 4096 fÃ©vr. 11  2017 ..
-rw-r--r--  1 root root 3106 fÃ©vr. 20  2014 .bashrc
-rw-r--r--  1 root root  140 fÃ©vr. 20  2014 .profile
-rw-r--r-- 1 root root 36 janv. 5 2015 .smbcredentials

sudo lsof -i -n -P | grep TCP

Determine the user + group which has ownership :

stat --format '%U:%G' "/bin/path"

ownership="$(stat --format '%U:%G' '/bin/path')"

Update ownership & right :

## app.R ##
library(shiny)
library(shinydashboard)

ui <- dashboardPage(
  dashboardHeader(),
  dashboardSidebar(),
  dashboardBody(print('Hello World'))
)
