CI/CD Flow w/ Github Actions to EC2 w/ Ubuntu Docker and Nginx

For use with: https://github.com/Two-Trees-Digital/turbo-temp

EC2 Setup

Go to Amazon account and create a new EC2
Choose the Ubuntu option
Choose a system size that suits your project needs
1. Medium and below is probably the most you’ll need with hobby projects
Create a .pem permissions file to be able to ssh into the system
Allot 12-20 GBs of space for system
Create Instance
Once Instance is created, go ahead and open a terminal where the .pem file got downloaded
1. Probably /user/downloads
Press ‘connect to instance’ and select the ssh tab
1. Copy paste that command into terminal
You’ve now connected to your instance
Proceed with downloading Docker

Docker

Nginx EC2

https://www.digitalocean.com/community/tutorials/how-to-install-nginx-on-ubuntu-20-04
Once through setup, you’ll need to go into your config file and input your settings
```
cd / etc / nginx;
```
```
cd sites-available
```
```
ls;
```
You’ll see a file named default here
1. We want to delete this
```
sudo rm -rf default
```
We now create a new default file with:
```
sudo nano default
```
Copy pasta your config settings:

Config File:

`server {``listen 80;``location / {``proxy_pass http://127.0.0.1:3000;``}``location /api/v1 {``rewrite ^/api/v1(/.*)$ $1 break;``proxy_pass http://127.0.0.1:3001;``}``location /dashboard/ {``rewrite ^/dashboard(/.*)$ $1 break;``proxy_pass http://127.0.0.1:3002;``}``}`;

Write out w/ ‘ctrl + O’
Exit w/ ‘ctrl + X’
We now want to cd out and into sites-enabled and delete the default file there too
```
cd ..
```
```
cd sites-enabled
```
```
sudo rm -rf default
```
Now we’re going to run a link command

Link Command:

sudo ln -s /etc/nginx/sites-available/default /etc/nginx/sites-enabled/default

Now restart the nginx server and we’re good to go!

Nginx Command:

sudo /etc/init.d/nginx start

sudo /etc/init.d/nginx restart

Github Actions

Set up of the actions are pretty straight forward

Go to your github repository, and go to the settings tab
Then go to Actions > Runners
Create New Self-Hosted Runner
Input the commands it prompts you with 1 by 1 at the root of your EC2
After sudo ./svc.sh start
1. Check the runners tab again to see your idle runner ready to go

Building the project

Running sudo docker ps shows there isn’t a built image of a container yet in the EC2
Make a test commit to the production or main branch of your code
1. Check the Actions tab in your repository to see a workflow run has been created
After the initial build completes, which may take a while, give sudo docker ps another try to see your container created!

Building Image

docker-compose build turbo-temp
 
docker-compose up --no-deps -d turbo-temp
