Description

Using ansible to deply a flask application on Linode. The original tutorial is located here

Steps

1. Create a Nanode on Linode using UBUNTU 20.04 LTS.

Login on Linode and create a Nanode (or Linode)

2. On your host (laptop/computer) install Ansible

pip install ansible

Screenshots

1. Choose Ubuntu 20.04 LTS
2. Choose your preferred Region
3. Choose Nanode or Linode
4. Choose a password for this tutorial
5. I would suggest that you add a ssh key. That will ease the login to the Remote Host (see point 5)

3. git clone this repo && change diirectory

git clone git@github.com:guinslym/linode_tutorial_deploying_a_flask_application_with_ansible.git
cd linode_tutorial_deploying_a_flask_application_with_ansible

4. Edit the Inventory file

Add your Nanode IP address in the `inventory` file to replace all **???** and add your Nanode **password** into this file. For security reasons it's better to use ansible-vault for password. But for this tutorial we can use leave it blank. **For production servers*** please use ansible-vault.

[all:vars]
ansible_python_interpreter= /usr/bin/python3

[flaskbox_dev]
???.??.???.?? ansible_ssh_user=root ansible_ssh_pass=myPasswrd2

[flaskbox_prod]

5. Try to login to your Nanode to add the ECDSA key fingerprint on your host (laptop/machine)

$ ssh root@???.???.?.??
The authenticity of host '???.???.?.?? (???.???.?.??)' can't be established.
ECDSA key fingerprint is SHA256:cKRKaNMOcD7yuT6lOoqrte8oNmDuczXM47mcgmFPAFg.
Are you sure you want to continue connecting (yes/no/[fingerprint])? yes

once logged in, exit the remote host

root@localhost:~# exit

5. Run the Ansible playbook

ansible-playbook -i inventory ubuntu20-04.yml 

Todos

1. Add virtualenv
