# 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:

```bash
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:

	```bash
	# 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

```sql
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';
```
