Deployer: deploy your shit and make it run

So lame to have to configure nginx, MySQL, and your filesystem to install a stupid Wordpress instance.

Deployer does my config for me like the slave it is.

All the configuration is defined in group_vars/all/vars.yml, go check.

Create a side group_vars/all/vault.yml for your secrets, and encrypt it with Ansible Vault:

ansible-vault encrypt group_vars/all/vault.yml
# other sub-commands: edit, decrypt...

I usually run the following command:

ansible-playbook --ask-vault-pass sites.yml -i inventory -v

Required packages on remote

Python modules:

  • docker
  • docker-compose
  • pymysql

TODO: Ansible task to install that before the rest

Features

  • Creating Wordpress instances (yoohoo, da best)

    • That send mail!!11!1!
    • Supports existing and new installs
  • Creating Drupal instances

    • Only existing ones (no new installs)
  • Create Gitea instances

    • Nginx and docker-compose configurations
    • Most of the work is by hand, because there is quite a lot of interaction between the host and the container (for forwarding ssh).

Does not support

  • Setting up the host

  • SSL certificate creation (bro, do it yourself!). That is:

    # Make an nginx file for certbot 
    cat << EOF > /etc/nginx/sites-enabled/yoursite.com
    server {
    	listen 80;
    	server_name www.yoursite.com yoursite.com;
    	include snippets/letsencrypt.conf;
    }
    EOF
    nginx -t # Is everything alright?
    # If so, restart nginx
    service nginx restart 
    # Create the certificate
    certbot certonly --webroot -w /var/www/letsencrypt -d yoursite.com -d www.yoursite.com
    # Remove the stupid file
    rm /etc/nginx/sites-enabled/yoursite.com
    service nginx restart
    

Useful SQL commands

select host, user, password from mysql.user order by user;
create user 'arvuhez'@'172.26.0.2' identified by 'kjhs';
grant all on arvuhez.* to 'arvuhez'@'172.26.0.2';
show grants for 'arvuhez'@'172.26.0.2';
