Development

These are the steps required to setup the docker container for development.

Setup

Download the source code

$ git clone https://github.com/nuber-io/nuber

Download dependencies and setup the environment for the installation.

$ cd nuber
$ composer install
$ bin/install
$ npm install ./websocket

Create the database and tables, also setup the database for testing.

$ bin/console db:setup
$ bin/console db:migrate
$ bin/console db:test:prepare
$ chown -R www-data:www-data data

Build the container

$ docker-compose build

Usage

Once you have built the docker image, you can work with it like this

To start the container

$ docker-compose up

Check this works fine https://localhost:3000

Once the Docker container has been started, you can go into it by running the following command:

$ docker-compose exec nuber bash

Enable debug mode by setting the APP_DEBUG environment variable to true, you may need to delete config/.env.php which is the cached version.

$ nano config/.env

Once your done open your browser and goto https://localhost:3000/install. You should get a certificate warning because the certificate self signed, proceed anyway.

If you are using Google Chrome, you will need to enable self signed certs by opening chrome://flags/#allow-insecure-localhost

Follow the instructions, and on the next page enter the IP address and following the instructions for configuring the LXC host. LXD can't be installed in Docker, I use virtual box with a Ubuntu server and a fixed IP address, e.g. 192.168.1.150.

LXD

To setup the LXD host

$ lxc config set core.https_address "[::]:8443"
$ lxc config set core.trust_password "00000000-0000-0000-0000-000000000000"

To see instance logs

$ lxc info alpine --show-log

LXD logs

$ sudo cat /var/snap/lxd/common/lxd/logs/lxd.log

Checking out SNAP journal

$ journalctl -u snap.lxd.daemon -n 100

To list container info on ZFS

$ zfs list

Whilst on BTRFS, go to the directory

$ /btrfs/containers/alpine

To see BTRFS usage

$ sudo btrfs fi show
Label: none  uuid: 916f6d6a-c243-477c-b43b-20d12eb15518
	Total devices 1 FS bytes used 10.88GiB
	devid    1 size 53.50GiB used 21.03GiB path /dev/sda3

To enable debug mode, if you reall get stuck then run the command and check the logs

sudo snap set lxd daemon.debug=true; sudo systemctl reload snap.lxd.daemon
sudo tail -f /var/snap/lxd/common/lxd/logs/lxd.log
