Recipes to setup infrastructure and deploy disinfo.quaidorsay.fr website and API

Recettes pour mettre en place l'infrastructure et déployer le site web et l'API de disinfo.quaidorsay.fr

Requirements

• Install Ansible
• Install required Ansible roles ansible-galaxy install -r requirements.yml

See troubleshooting in case of errors

[For development only] Additionals dependencies

To test the changes without impacting the production server, a Vagrantfile is provided to test the changes locally in a virtual machine. VirtualBox and Vagrant are therefore required.

• Install VirtualBox
• Install Vagrant

Configuration

Allow decrypting all sensitive data.

A password is needed to decrypt encrypted files with ansible-vault. Get the password from the administrator and copy it in a vault.key file at the root of this project, it will avoid entering it every time you run a command.

[For developement only] Configure your host machine to access the VM.

Edit your hosts file /etc/hosts, add the following line so you can connect to the VM to test deployed apps from your host machine's browser:

192.168.33.11    disinfo.local

Now on your browser you will be able to access deployed app on the VM with the URL http://disinfo.local to mimic the real architecture of our servers

The guest VM's IPs can be changed in the VagrantFile:

Usage

To avoid making changes on the production server by mistake, by default all commands will only affect the vagrant developement VM. Note that the VM needs to be started before with vagrant up.
To execute commands on the production server you should specify it by adding the option -i inventories/production.yml to the following commands.

• Setup a phoenix server:

Before all, following backup steps are required:

Prepare data to be copied on the server

• Login to disinfo server
• Create a dump of the Mattermost MySQL database on the remote server with mysqldump -u root mattermost -p -r /tmp/dump.sql. (You will find the password by decrypting the password file ansible-vault decrypt inventories/group_vars/all/vault.yml and looking for vault_mysql_root_password)
• Create a copy of Mattermost data files with mkdir -p /tmp/mattermost/data && sudo cp -a /opt/mattermost/data/ /tmp/mattermost
• Changes Mattermost data files permissions sudo chown debian -R /tmp/mattermost/data
• Logout of disinfo server

Copy exported data on your local machine

• Copy the resulting dump to the Mattermost role's files on your local machine with: scp -r -p [email protected]:/tmp/dump.sql ./roles/infra/mattermost/files.
• Copy Mattermost data files to the Mattermost role's files on your local machine with: scp -r -p [email protected]:/tmp/mattermost/data ./roles/infra/mattermost/files.
• Copy all scrapped political ads data to the new server directly (there is more than 500Go). Connect to disinfo.quaidorsay.fr server and run: rsync -azP /mnt/data/political-ads-scraper/ [email protected]:/mnt/data/political-ads-scraper.

ansible-playbook playbooks/site.yml

• Setup infrastructure only:

ansible-playbook playbooks/infra.yml

• Setup apps only:

ansible-playbook playbooks/apps.yml

• Setup one app only:

ansible-playbook playbooks/apps/<APP_NAME>.yml

You can find all available apps in playbooks/apps directory.

For example, to setup only media-scaleapp on the new server:

ansible-playbook playbooks/apps/media-scale.yml

• Setup one sub part of the infra:

ansible-playbook playbooks/infra/<MODULE>.yml

You can find all available modules in playbooks/infra directory.

For example, to setup only MongoDB on the new server:

ansible-playbook playbooks/infra/mongodb.yml

Options and tags

Options

Ansible provide among many others the following useful options:

• --diff: to see what changed.
• --check: to simulate execution.
• --check --diff: to see what will be changed.

For example, if you modify the nginx config and you want to see what will be changed you can run:

ansible-playbook playbooks/infra/nginx.yml --check --diff

Tags

Some tags are available to refine what will happen, use them with -t:

• setup: to only setup system dependencies required by the app(s) (cloning repo, installing app dependencies, all config files, and so on…)
• start: to start the app(s)
• stop: to stop the app(s)
• restart: to restart the app(s)
• update: to update the app(s) (pull code, install dependencies and restart app)

For example, you can update all apps by running:

ansible-playbook playbooks/apps.yml -t update

…or update only media-scale:

ansible-playbook playbooks/apps/media-scale.yml -t update

…or restart only panoptes:

ansible-playbook playbooks/apps/panoptes.yml -t restart

commands

In order to deploy here are the corresponding commands TODO: make a deploy script

deploy:local:disinfo		    ansible-playbook servers/disinfo/site.yml -i inventories/dev-fix.yml
deploy:local:disinfo:nginx  ansible-playbook playbooks/infra/nginx.yml -i inventories/dev-fix.yml
deploy:local:disinfo:docker ansible-playbook playbooks/infra/docker.yml -i inventories/dev-fix.yml
deploy:disinfo          	  ansible-playbook servers/disinfo/site.yml -i inventories/production.yml --check --diff
deploy:disinfo:nginx        ansible-playbook playbooks/infra/nginx.yml -i inventories/production.yml --check --diff
deploy:disinfo:docker       ansible-playbook playbooks/infra/docker.yml -i inventories/production.yml --check --diff
deploy:disinfo:mongo        ansible-playbook playbooks/infra/mongodb.yml -i inventories/production.yml --check --diff

mongo:restart	              ansible-playbook playbooks/infra/mongodb.yml -i inventories/production.yml --tags restart

Troubleshooting

Failed to connect to the host via ssh: Received disconnect from 127.0.0.1 port 2222:2: Too many authentication failures

Modify ansible ssh options to the inventories/dev.yml file like this:

all:
  children:
    dev:
      hosts:
        '127.0.0.1':
          […]
          ansible_ssh_private_key_file: .vagrant/machines/default/virtualbox/private_key
          ansible_ssh_extra_args: -o StrictHostKeyChecking=no -o IdentitiesOnly=yes
          […]

Or alternatively you can use the dev-fix config by appending -i ops/inventories/dev-fix.yml

ansible: command not found

if you're on mac OSX and tried to install with pip install ansible you may need to add python's bin folder to your path with

export PATH=$PATH:/Users/<yourusername>/Library/Python/3.7/bin

~/.netrc access too permissive: access permissions must restrict access to only the owner

on linux

chmod og-rw /home/<yourusername>/.netrc

on mac OSX

chmod og-rw /Users/<yourusername>/.netrc
