KUSANAGI Runs on Docker

This guide will explain how to create a WordPress environment using KUSANAGI Runs on Docker (KUSANAGI RoD).

Overview

KUSANAGI RoD runs the Ultrafast WordPress Virtual Machine KUSANAGI on a Docker Machine.
KUSANAGI RoD offers the same high speed WordPress execution environment as KUSANAGI, but since it is in beta, the following restrictions apply.

  • ・Operating environment
    You can use Nginx, PHP 7, PHP 5 and MariaDB.
    We will expand to Apache2(httpd) and HHVM at a later time.
  • ・KUSANAGI commands
    You cannot use KUSANAGI commands.
    The “kusanagi provision” and  “bcache/fcache” commands are performed by editing “docker-compose.yml”
  • ・SSL
    You cannot use Let’s Encrypt’s SSL service.
    We will add SSL support at a later time.

Installation

You need Docker, Docker Machine, and Docker Compose to use KUSANAGI RoD.
Installation instructions are as follows.

Docker

Choose the Docker installation for your OS.

Docker Machine

Install Docker Machine from the following:

Docker Compose

Install Docker Compose from the following:

On Windows, installing Docker Toolbox will install Docker Compose as well.

Create a Docker Machine

You can control Docker using your Docker Machine on the local VirtualBox or a cloud platform (such as Microsoft Azure, AWS EC2, etc.)

On VirtualBox

View Get started with Docker Machine and a local VM and create a Docker Machine on VirtualBox. In the following example, we created the Docker Machine “kusanagi-machine”.

# docker-machine create --driver virtualbox --virtualbox-memory=8192 --virtualbox-cpu-count=2 kusanagi-machine

Use the following command to confirm the details of your Docker Machine.

# docker-machine ls                                                                 
NAME                    ACTIVE   DRIVER       STATE     URL                         SWARM   DOCKER    ERRORS         
kusanagi-machine        *        virtualbox   Running   tcp://192.168.99.100:2376           v1.11.1 
# docker-machine env kusanagi-machine
export DOCKER_TLS_VERIFY="1"
export DOCKER_HOST="tcp://192.168.99.100:2376"
export DOCKER_CERT_PATH="/root/.docker/machine/machines/kusanagi-machine"
export DOCKER_MACHINE_NAME="kusanagi-machine"
# Run this command to configure your shell:

On Azure

View Use Docker Machine with the Azure driver and create a Docker Machine on Microsoft Azure. In the following example, we created the Docker Machine “kusanagi-machine”. We set our region as Japan East, and the VM size to Standard_D1.

# docker-machine create -d azure --azure-ssh-user rod \
  --azure-subscription-id <Your AZURE_SUBSCRIPTION_ID> \
  --azure-location "Japan East" \
  --azure-size "Standard_D1" \
  --azure-open-port 80 \
  kusanagi-azure

Occasionally you will be asked to verify your account, so access the webpage shown and enter the code.

(kusanagi-azure) Microsoft Azure: To sign in, use a web browser to open the page https://aka.ms/devicelogin. Enter the code XXXXXXXXX to authenticate.

Use the following command to confirm the details of your Docker Machine.

# docker-machine ls kusanagi-azure                                           
NAME               ACTIVE   DRIVER       STATE     URL                         SWARM   DOCKER    ERRORS
kusanagi-azure     -        azure        Running   tcp://XXX.XXX.XXX.XXX:2376              v1.11.1 
# docker-machine env kusanagi-azure
export DOCKER_TLS_VERIFY="1"
export DOCKER_HOST="tcp://XXX.XXX.XXX.XXX:2376"
export DOCKER_CERT_PATH="/root/.docker/machine/machines/kusanagi-azure"
export DOCKER_MACHINE_NAME="kusanagi-azure"
# Run this command to configure your shell: 
# eval $(docker-machine env kusanagi-azure)

Create KUSANAGI RoD with Docker Compose

Next we will create KUSANAGI RoD by using Docker Compose.

  • (1) Download kusanagi-docker from GitHub.
＃ git clone https://github.com/prime-strategy/kusanagi-docker.git
# cd kusanagi-docker
# ls -A                                                                                                            
.git   LICENSE  README.md
  • (2) Like the README states, create “docker-compose.yml”. In the following example we created it using nginx-1.10.0-1 and php-7.0.6.
  • # cat docker-compose.yml
version: '2'
