A bash function to get inside a running docker container ... still needs tweaking, requires nsenter ( https://github.com/jpetazzo/nsenter )

getInside.sh

getInside() {
  # pass in a container ID
  CONTID=$1;
  # This prints out export commands you can paste into the terminal once inside the container - not always needed
  sudo docker inspect $CONTID | awk '/(PATTERN FOR ENV VARIABLES YOU CARE ABOUT)/ { gsub(/[",]/,"",$1); print "export " $1 } '
  # Get the process ID
  PID=$(sudo docker inspect --format {{.State.Pid}} $CONTID );
  # Status message
  echo "Entering container $CONTID with PID $PID";
  # Enter the container
  sudo nsenter --target $PID --mount --uts --ipc --net --pid
}
