For a project I need to do this
On an EC2 (AWS) instance install docker and in docker a wordpress site with wp-cli. I already have a database (RDS)
So it will be necessary that wordpress (on docker) this automatically connects to my database and also that this is the address of the load balancing that is taken into account because there will be several machines (3 instance) that can be created automatically according to the needs.
So it will be necessary that each machine that will automatically create (scaling group) can connect to the database (RDS) by always taking the address of the load balancing and that the site is always online; if I make a change this impacts on other machines or future machine creates
How to do this?
thank you
