This document is intended to aid the development workflow described in Developer HowTo for UI Module for Open Source Mano.

In order to develop in your preferred IDE/text editor, you can "bind mount" a directory from your local computer into an LXD container running on the same host.

First, find out your uid:

$ id
id
uid=1000(stone) gid=1000(stone) groups=1000(stone),4(adm),24(cdrom),27(sudo),30(dip),46(plugdev),113(lpadmin),128(sambashare),129(lxd),131(kismet),138(libvirtd)

#!/bin/bash


# Huge pages 1G auto mount
mkdir -p /mnt/huge
if ! grep -q "Huge pages" /etc/fstab
then
 echo "" >> /etc/fstab
 echo "# Huge pages" >> /etc/fstab
 echo "nodev /mnt/huge hugetlbfs pagesize=1GB 0 0" >> /etc/fstab

1. Create a launchpad branch of the deployable charm

[~/charms/layers/fluentd] $ charm build
