I have no idea what to do with this

But I'm gonna save it anyways because it seems important

In reality

ssh into server 
Cd into project directory 
Git pull and rebase 
Check the current port of the active container 
Pick a port to use (usually alternate between 2 ports) 
backup dockerfile and env files 
Delete env file to avoid conflicts 
Create new one and add new env 
Build new container with a -new prefix 
Once built 
Do a curl in the action to make health checks every few seconds until I get a 200

Timeout in 1 min and rollback if I never get a 200

If I get a 200 
Proceed to Nginx config file 
Replace :port with new port 
Reload nginx

Traffic now on new container 
Wait 1 minute

Delete old container

Rename new container (remove -new) on it

Action ends
