mfcloud 0.2.2

Production cloud deployments of fig infrastructure with docker

mfcloud
======

mfcloud alows to deploy your fig infrastructure to remote servers . Also it
provides all the services needed for hosting production apps.

Features:

- define your app config through Dockerfile and fig.yml
- easy deploy through git push
- pushing several versions of app (dev, staging, production ... etc)
- haproxy based balancer tcp
- easy switch balancer endpoint between app versions (ex swap prod and dev)
- persistent storage for containers
- easy copying persistence storage between containers (prod -> staging, etc)
- push and pull persistent volumes from your production server

Installation
-------------

Install docker: http://docs.docker.io/en/latest/installation/

Make sure you can run docker containers::

sudo docker run -i -t ubuntu echo -e "OK";

Install packages::

sudo apt-get install python-pip python-dev
sudo pip install mfcloud

Test that mfcloud is working::

$ mfcloud-server app-list

+-----+---------+-------+
| App | Version | State |
+-----+---------+-------+
+-----+---------+-------+

Create mfcloud user (you can pick any username)::

sudo useradd -s /bin/bash -d /home/mfcloud -m mfcloud
sudo su mfcloud
cd /home/mfcloud
mkdir ~/.ssh
vim ~/.authorized_keys # insert your ssh key and ssh key of your root user into this file
chmod -R go-rwx ~/.ssh

Test you can ssh into your server using mfcloud account::

ssh [e-mail]

Make sure your root user can also access your server::

sudo ssh [e-mail]

Add mfcloud user to docker group::

sudo usermod -a -G docker mfcloud

Check mfcloud can run docker now::

sudo su mfcloud
docker run -i -t ubuntu echo -e "\033[0;32mMfcloud can run Docker - OK\033[0m";
exit

Install haproxy::
sudo apt-get install haproxy
sudo echo "ENABLED=1" | sudo tee /etc/default/haproxy
sudo service haproxy start
sudo curl https://raw.github.com/pywizard/mfcloud/master/examples/haproxy.cfg.tpl | sudo tee /etc/haproxy/haproxy.cfg.tpl

Now install incron to reconfigure haproxy, when you deploy new apps::

sudo apt-get install incron
sudo echo "root" | sudo tee /etc/incron.allow

Edit incrontab file and insert lines generated by inotify-dump in incrontab file::

mfcloud-server inotify-dump

/home/mfcloud/apps-conf IN_MODIFY,IN_CREATE,IN_DELETE,IN_NO_LOOP /usr/local/bin/mfcloud-server balancer-dump /home/mfcloud/apps-conf
/etc/haproxy/haproxy.cfg.tpl IN_MODIFY,IN_CREATE,IN_DELETE,IN_NO_LOOP /usr/local/bin/mfcloud-server balancer-dump /home/mfcloud/apps-conf

$ sudo incrontab -e

And the last thing. Allow mfcloud to read-write any docker container volume:

mfcloud ALL= NOPASSWD:/usr/bin/rsync


Install git:

sudo apt-get install git


Deployement
-------------

Start by creating application that is working locally using fig.yml

Set working ssh account::

$ mfcloud use [e-mail]

Create an application:

$ mfcloud remote app-create foo

Deploy code:

$ git push [e-mail]:apps/foo master:prod

Check port number:

$ mfcloud remote app-list

Configure balancer:

$ mfcloud remote balancer set mydomain.com web:80@foo#prod

Push volume to deployment:

$ filcoud volume-push web/code@foo#master

Push volume from deployment:

$ filcoud volume-pull web/code@foo#master

Remote volume copy:

$ mfcloud remote volume-copy web/code@foo#master foo#v1

Your app is deployed!
