simple_server_express's Introduction

simple_server_express

This project requires the following Repository Secrets to be updated(Github Secrets > Actions > Repository Secrets).

DEV_GITHUB_USER
- Set to pmeaney
- Doesn't need update
DEV_KEY_PRIVKEY_NOPASS_3_26_23
- When we generated the Server with terraform, we provide in the terraform file a public key we use to boot the server (and then log into it-- via our laptop). This is the ssh private key associated with that public key.
- Needs update (If we intend to pull this onto a new server and is not the same as key pair where public key used in terraform script)
- Note: I need to go back and check if it will work with a key pair which has a pw
DEV_SERVER_IP
- Needs update (If we intend to pull this onto a new server)
DEV_SSH_USER
- Doesn't need update (as long as its the same one as terraform script)
GH_PAT_3_26_23
- Doesn't need update

Several of the above items are used for the following:

In a Github Action, github spins up a tempoary CICD Server to do some work for us: Package up our app into a Container, and Deploy our app to our server.
So, we need that temporary Github Ubuntu Server to first be able to access our Hosting Server (e.g. Digital Ocean server).
What we have to do first though, before we can access Hosting Server, is provide the necessary secrets & keys to the temporary Github CICD server.

- name: Take ssh key from github repo, copy it into the ubuntu VM, so we can access the server & download the docker image
