My first blog and my first post.

The reason to start a blog ? The Why ? (I've just finished reading Start with Why by Simon Sinek....)

• Share my experience and projects
• Learn about your experience and projects

Although in the last 100 years technology improve our lives quality about a 10x factor, we still study/learn in the same way of 2000 years before. Write and read are still the best method to share knowledge.

So, here I am.

In honour of the Daniel Pennac's ten rules I'll follow 3 simple rules to make more enjoyable reading this blog:

1. Don't write more than 900 words;
2. Be interesting (don't try to be, remember Yoda ?);
3. Write for your and my fun

So I'll don't overwhelming you with hundreds of thousands of sentences about who come first between egg or chicken. I'll figure out the best I can write about my entreprenurship plan, experience, hobbies, travel (I'm planning to see some countries) and about my strange country (Italy).

I think is always interesting to know what there is behind something, for example behind this blog. Well, I love python and after start this blog with django I choose to use Nikola, a simple and powerful static site generator and hosting it with github.

The dynamic part of the site is based on javascript and ajax calls to a simple django backend. You can use this url api.chrisbarra.me/api/quote/get to get a random quote (json format) or api.chrisbarra.me to see a simple html page.

Back to architect, I use a Digital Ocean vps, with Ubuntu and Docker. Docker is awesome, for the first 2 hours. After that I have a form of hate and love (much love than hate), but I'll talk about this in the next weeks.

I have 1 simple docker container with python, uWSGI and NGINX.

Here you can find my repo with my docker and config files.

Now ssh your digital ocean vps or whatever you want to use

ssh root@ipyourhostmachine

Change your dir

# Clone git repository of your project or change your directory with your ROOT
# project directory, this is very important because this command "ADD ./ /app"
# copy all your files from your current directory to the /app container's dir
cd rootprojectdir

Download my Dockerfile

# Always from ROOT directory of your project download my Dockerfile
# remember to change your uwsgi.ini if your wsgi.py is not located in api/wsgi.py dir
# More information in my Dockerfile
sudo curl -o Dockerfile https://raw.githubusercontent.com/barrachri/dockerfiles/master/dockerfile/Dockerfile_app

Build image from Dockerfile and name it appserver_image

docker build -t appserver_image .

Run a container from appserver_image and expose port 80 from the container to port 80 of the host machine and name this container appserver

docker run -d -p 80:80 --name appserver appserver_image

We looking for mount point directories between our container and host machine

docker inspect --format='{{.Volumes}}' appserver

The output will be something like this

map[
/app:/var/lib/docker/vfs/dir/strangehashcode
/etc/nginx/sites-enabled:/var/lib/docker/vfs/dir/strangehashcode
/var/log/nginx:/var/lib/docker/vfs/dir/strangehashcode]

If you want to stop and restart your container

docker stop appserver
docker start appserver

If something went wrong simple

docker logs appserver

After that we need to set this container to start automatically, we can do that with supervisor

sudo apt-get install supervisor
sudo nano /etc/supervisor/supervisord.conf

And add this text at end

[program:appserver]
command=/usr/bin/docker start -a appserver

Save and then

sudo reboot

Now your python app should be online !

I hope this was useful for other questions I’m here !

Tsuduku !
