Terraform reads all files in the directory and essentially combines them into one big file. The infrastructure essentially consists of three files: the network setup, the instances, and some additional provisioning details.
I’ve split the code into two repositories: the project itself, and the infrastructure. As it’s what a lot of the cool kids are using today, we’ll use this for the grouporder project.
Terraform is software from the same guys who make Vagrant and Consul, that allows us to write our desired state in a language that’s a lot user-friendlier than CloudFormation JSON. CloudFormation is a solution that allows us to describe a desired infrastructure in JSON which can then be applied to AWS. The CLI makes scripting easy, but it’s hard to make scripts that are idempotent and allow for easy changes. The next options come from AWS themselves: the CLI and CloudFormation. However, that would be hard to reproduce, and impossible to version control. We could manually go into the AWS Console and configure everything from there. Now that we know the configuration we want on AWS, we need a way to make it happen.
It would be very hard to install PostgreSQL on it without it.
Not shown in the diagram is the NAT gateway that’s necessary to make sure we can access the internet from the DB host. We’ll also run Ansible configuration changes from this box.Īs only the management and web hosts need to be exposed to the internet, we can put the database host in a private subnet. We’ll use that as an SSH bastion to connect to the other machines. In line with this practice, we’ll add a third EC2 instance to be a ‘management host’. To keep in line with best practices, we’ll want to make only the absolutely necessary ports open. We’ll create a two-tier environment on AWS: a web server, and a database server. There are some difficulties on Windows with the SSH configuration for Terraform.
This blog post was written on Ubuntu it should work as well on macOS.
If you’re interested in seeing how to prepare this application for production, let me know in the comments! The environment we’ll describe here is configured for development, not production. Today, we’ll take our app to AWS, and we’ll set up a remote development environment.
GitHub is the canonical location of this project.In the last two blog posts of this series we discussed how to set up a local VM-based development environment for a cloud application, and then built a Flask-RESTful app within this environment. You can disable the default behavior by using the -nostaticįeel free to open pull requests or issues. Otherwise, you may see 404s when requesting static files. If you're using a wrapper around your WSGI application such as dj_static or WhiteNoise, you probably want to let it handle serving You can tell Django SSL Server to use it with the following arguments: $ python manage.py runsslserver -certificate /path/to/certificate.crt -key /path/to/key.key If you have a certificate/key pair from a certificate authority, Option 2: Use a certificate from a CA that your browser trusts, for example Letsencrypt. The mechanism for this varies from browser to browser. Tab, by installing sslserver/certs/development.crt as a trusted certificate. You can do this in your browser's "advanced settings" Option 1: Tell your browser to explicitly trust the certificate. There are two options for making the certificate warning go away in development: SSL certificate, the server tells the user, "I'm Bank of America, because VeriSign said so (or any other commercial certificate authority)." The server is effectively telling the user, "I'm such-and-such server, because I said so". This is expected.ĭjango SSL Server ships "batteries included" with a self-signed server certificate. Using the default settings, your local browser will make all sorts of noise that it doesn't trust the certificate. You'll now be able to access your Django app on Browser Certificate Errors IPv6 support: $ python manage.py runsslserver -6 :7443 Start a SSL-enabled debug server: $ python manage.py runsslserverĪnd access app on or start server on specified port: $ python manage.py runsslserver 127.0.0.1:9000 Install the module in your Python distribution or virtualenv: $ pip install django-sslserverĪdd the application to your INSTALLED_APPS: INSTALLED_APPS = (. Webserver such as Apache or NGINX handles SSL. ThisĪpp is intended for special use-cases. Please note that this should not be used for production setups. Django SSL Server is a SSL-enabled development server for the Django Framework.
