Let’s change that to 127.0.0.1: g.db = nnect(dbname='flaskapp', In the Flask application, the database host was set to ‘db’ for the Docker Compose configuration. If we look back at P圜harm, we should see the stack trace in the debug window, which shows us that we still need to finish up the database connection. In the wise words of Butters Stotch: oh hamburgers. Now click the debug button to start Flask: On AWS you need to add a new rule to the security group to allow inbound traffic on TCP port 5000 from 0.0.0.0/0.

If you’re running this code on AWS or a similar provider, you may need to open port 5000 in the firewall. We need to provide host=0.0.0.0 as an additional option to Flask: Let’s edit it first, so it’s accessible from the outside world. Now that we’ve taken care of that, we can run our Flask run configuration. Change the path to the Python executable inside the virtualenv ( /home/ubuntu/venv/bin/python): Use the gear icon to choose ‘Show all’, and then click the pencil to edit the interpreter. In order to do so, go back to the interpreter settings screen.

We can do some more cool things with Ansible, like configuring our virtualenv: - name: Install pipĪfter we add these tasks to our playbook (setup.yml) and re-run them, we can then re-configure P圜harm to use the remote venv rather than our box’s system interpreter.

You can do this by running these commands on the server (use the SSH session you started earlier): sudo apt update & sudo apt install -y ansibleĪnd look at that, PostgreSQL is installed: So let’s install Ansible, navigate to this folder, and run this file (called a playbook in Ansible terminology). By default, this is a subfolder of /tmp/. If we create a new file setup.yml with those contents, P圜harm will then automatically upload it to the location we configured during project configuration.

Installing PostgreSQL with Ansible looks like this: - hosts: localhost With Ansible, we can describe the desired state of our Linux server in YAML files, and then use the Ansible tooling to apply the desired configuration. If we’re developing an application, it makes sense to document what we’re doing and make sure that we can reproduce the environment later.Ī great tool for configuring the state of a Linux machine is Ansible. If you’re experimenting on your Raspberry Pi, that’s the way to go. To open an SSH session, either go to Tools | Start SSH session, or use Ctrl+Shift+A to find the ‘Start SSH session’ action:Īt this point, we could just run sudo apt-get install postgresql. So let’s start with installing PostgreSQL. If we want to make this work on a general Linux machine, we’ll need to handle this configuration ourselves. Configuring Our Boxĭocker Compose is very handy, as it allows us to specify and configure services in a very concise way. For example, if you open the Python console, you can run code on your remote box:īefore we can run our Flask script, there are a couple more things we need to take care of. As this is the case for AWS current Ubuntu 16.04 AMI, we’ll make sure to change the interpreter path:Īfter we finish configuring the interpreter, we’re ready to run code. The only exception is if your Linux box only has Python 3 installed, and doesn’t link /usr/bin/python to that version. Then, follow the instructions to connect to your SSH box:įor this tutorial, we’ll mostly accept the default values.

If you don’t see SSH, please make sure you’re using P圜harm Professional 2018.1 or later. To configure the interpreter, open Settings | Project Settings, and use the gear icon to add an interpreter:Ĭhoose SSH on the left-hand side. I’ll be using an AWS EC2 instance, but you can use any other Linux box (including a Raspberry Pi). After opening the project, we need to configure our server. Let’s start by cloning the repository, and then checking out the ‘with-database’ branch. In last year’s blog post, I used Docker Compose to describe an environment with both the Python service and a PostgreSQL database. The application is a very simple old-school guestbook. I’m lazy, so we’ll use a web-app that I made last year as an example. So let’s have a look to see how we can connect P圜harm to a VPS box. If we want to develop in an environment similar to our production environment, how could we approach this? The closest would be to set up a second VM for development purposes. If you’re using a traditional web-host, this is referred to as VPS hosting. Most web applications are deployed to some sort of Linux VM. Although in most cases it’s not possible to provide an exact copy of the production environment for development, pursuing dev-prod parity is a worthwhile cause. One common cause of bugs in many applications is that development and production environments differ.
