Start by editing the wpa-supplicant config file:
sudo nano /etc/wpa_supplicant/wpa_supplicant.conf

network={
    ssid="YOUR_NETWORK_SSID"
    psk="WIFI_PASSWORD"
}

Download docker with:
https://github.com/moby/moby/issues/38175
sudo apt-get install docker-ce=18.06.1~ce~3-0~raspbian

Docker compose can be installed as usual

Im using ngnix to forward mqtt requests from client to pi(conf.d):
server {                                                                   
    listen 1883;                                                              

    server_name YOUR_IP_ADDRESS;                                              

    proxy_redirect off;                                                       
    proxy_buffering off;                                                      
    proxy_set_header Host $host;                                              
    proxy_set_header X-Real-IP $remote_addr;                                  
    proxy_set_header X-Forwarded-For $proxy_add_x_forwarded_for;              

    location / {                                                              
        proxy_pass http://127.0.0.1:1883;                                            
    }                                                                         
}  

as raspberry uses ARM procesors, not all docker images are aviable
Be carefull when using non-offical docker images as they can be tempered with and you can't trust them
