#!/usr/bin/env bash

Echo commands

set -o xtrace

Exit on error to stop unexpected errors

set -o errexit

Keep track of the current directory

TOOLS_DIR=$(cd $(dirname "$0") && pwd)
TOP_DIR=$(cd $TOOLS_DIR/..; pwd)

Import common functions

. $TOP_DIR/functions

Change dir to top of devstack

cd $TOP_DIR

Source params

source ./stackrc

Echo usage

usage() {
    echo "Add stack user and keys"
    echo ""
    echo "Usage: $0 [full path to raw uec base image]"
}

Make sure this is a raw image

if ! qemu-img info $1 | grep -q "file format: raw"; then
    usage
    exit 1
fi

Mount the image

DEST=/opt/stack
STAGING_DIR=/tmp/`echo $1 | sed  "s/\//_/g"`.stage.user
mkdir -p $STAGING_DIR
umount $STAGING_DIR || true
sleep 1
mount -t ext4 -o loop $1 $STAGING_DIR
mkdir -p $STAGING_DIR/$DEST

Create a stack user that is a member of the libvirtd group so that stack is able to interact with libvirt.

chroot $STAGING_DIR groupadd libvirtd || true
chroot $STAGING_DIR useradd $STACK_USER -s /bin/bash -d $DEST -G libvirtd || true

Add a simple password - pass

echo $STACK_USER:pass | chroot $STAGING_DIR chpasswd

Configure sudo

( umask 226 && echo "$STACK_USER ALL=(ALL) NOPASSWD:ALL" \
    > $STAGING_DIR/etc/sudoers.d/50_stack_sh )

Copy over your ssh keys and env if desired

cp_it ~/.ssh $STAGING_DIR/$DEST/.ssh
cp_it ~/.ssh/id_rsa.pub $STAGING_DIR/$DEST/.ssh/authorized_keys
cp_it ~/.gitconfig $STAGING_DIR/$DEST/.gitconfig
cp_it ~/.vimrc $STAGING_DIR/$DEST/.vimrc
cp_it ~/.bashrc $STAGING_DIR/$DEST/.bashrc

Copy devstack

rm -rf $STAGING_DIR/$DEST/devstack
cp_it . $STAGING_DIR/$DEST/devstack

Give stack ownership over $DEST so it may do the work needed

chroot $STAGING_DIR chown -R $STACK_USER $DEST

Unmount

umount $STAGING_DIR
