Requirement

key
At first, go to the EC2 section and create the key then store it in a safe place. This key is needed for accessing EC2 VMs.
S3 role
Storing cloud_user_accessKeys in EC2 VMs is not safe so I should give EC2 instances a role that can access S3. For simplicity, I give full access to S3.
cloud_user_accessKeys
I want to update our code by Github so it should can access to our beanstalk by cloud_user_accessKeys.

Create Application

go to the Elastic Beanstalk section.
choose proper application name
in Platform choose PHP 7.4 running on 64bit Amazon Linux 2 why this platform? Amazon Linux 2 use Nginx and PHP 7.3 have a bug in CICD.
upload your code as a zip file.
Select Configure more options
In Security Choose your EC2 key pair and IAM instance profile that you create in Requirement.
In Database write proper username and password
Select Create app
It takes a few minutes to show the final status
ssh to EC2 VMs and Import a SQL file into the created DB

    aws s3 cp BACKUP.sql s3://BUCKET_NAME
    mysql -u USER -h DATABASE-URL -p ebdb < BACKUP.sql 
    mysql -u USER -h DATABASE-URL -p -D ebdb -e "UPDATE users SET id=3 WHERE id=1;";

Data base username and password

I can not save username and password in plain text so I should use another way so in config/database.php I use

define('RDS_HOSTNAME',$_SERVER['RDS_HOSTNAME']);
define('RDS_USERNAME',$_SERVER['RDS_USERNAME']);
define('RDS_PASSWORD',$_SERVER['RDS_PASSWORD']);
define('RDS_DB_NAME',$_SERVER['RDS_DB_NAME']);

Nginx

Amazon Linux 1 (AL1) uses Apache2. However, Amazon Linux 2 (AL2) uses Nginx. After I use AL2 I get 404. so how can I solve that? I should add bellow part to /etc/nginx/conf.d/elasticbeanstalk/php.conf

location / {
     try_files $uri $uri/ /index.php?$query_string;
         gzip_static on;
}

I can add this after the VMs is created but I want to do it automatically so I should create .platform and put the php.conf in .platform/nginx/conf.d/elasticbeanstalk/php.conf

Copy .env from S3

I want to download .env from s3. in Create Application we assign S3fullaccess role to EC2. so I can run the S3 command without a secret key or access key. so I create .ebextensions folder and init.config file. In init.config I add


container_commands:
    02_get_env_vars:
      command: aws s3 cp  s3://BUCKET-NAME/.env .

install packages

I can install any packages by adding it to .ebextensions/init.config as below. packages:

  yum:
    curl: []
    git: []
    htop: []
    php-common-7.4.5-1.amzn2.x86_64: []
    php-fpm-7.4.5-1.amzn2.x86_64: []
    php-mbstring-7.4.5-1.amzn2.x86_64: []
    php-xml-7.4.5-1.amzn2.x86_64: []
    php-mysqlnd-7.4.5-1.amzn2.x86_64: []
    php-bcmath-7.4.5-1.amzn2.x86_64: []
    php-json-7.4.5-1.amzn2.x86_64: []

php-tokenizer php-curlphp-zip have been install when I install php-common-7.4.5-1.amzn2.x86_64

Composer install

First I install composer and then I install dependencies. so I add this block to init.config

container_commands:
    03-install-composer:
      command: "curl -sS https://getcomposer.org/installer | php"
    04-install-depenencies:
      command: "composer.phar install --optimize-autoloader"

php artisan and permissions

For run php artisan I should add this code to init.config

container_commands:
    05-generate-key:
      command: "php artisan key:generate"
    06initdb:
        command: "php artisan migrate"
    07-link:
      command: "php artisan storage:link"
    08-add-permission:
      command: "sudo chmod -R ug+rwx storage bootstrap/cache"

I can not run sudo chgrp -R www-data storage bootstrap/cache because there is no www-data group.

Setup a Supervisor

First I should add bellow code to init.config

container_commands:
    01-copy_systemd_file:
      command: "easy_install supervisor"
    02-enable_systemd:
      command: "mkdir -p /etc/supervisor/conf.d"
    03-copy_laravel-worker_config:
      command: "cp .ebextensions/laravel-worker.conf /etc/supervisor/conf.d/laravel-worker.conf"
    04-copy_supervidor_config:
      command: "cp .ebextensions/supervisord.conf /etc/supervisord.conf"
    05-touch_log:
      command: "mkdir -p /var/log/supervisor/ && touch /var/log/supervisor/supervisord.log"

and create laravel-worker.conf in .ebextensions

process_name=%(program_name)s_%(process_num)02d
command=php /var/www/html/artisan queue:work --tries=3
autostart=true
autorestart=true
user=root
numprocs=5
redirect_stderr=true
stdout_logfile=/var/www/html/storage/logs/worker.log

I can not run /bin/supervisord -c /etc/supervisord.conf by container_commands or commands because I should run it after deployment. It has different way in AL2 so be careful. I should create .platform/hooks/postdeploy directory and add 01_Supervisor.sh file. and in 01_Supervisor.sh I can run /bin/supervisord -c /etc/supervisord.conf

#!/usr/bin/env bash
touch /var/www/1.log
/bin/supervisord -c /etc/supervisord.conf

But after I launch this code I get permission denied error. so I should run chmod +x .platform/hooks/postdeploy/01_Supervisor.sh and after that, the error disappears.

Add a Cron entry

There are a lot of ways to do that but I do it by add below code to init.config

container_commands:
    01_remove_old_cron_jobs:
      command: "crontab -r || exit 0"
    02_cronjobs:
      command: "cat .ebextensions/crontab | crontab"
      leader_only: true

and add cron file to .ebextensions.

* * * * * php /var/www/medvoice/artisan schedule:run >> /dev/null 2>&1

The important part is adding new empty line at the end of cron file.

CI/CD

create .github/workflows/ folder and add php.yml. in php.yml I can deploy a code and say what I want to do for example I can create below part and get the timestamp and use it as version_label(version_label: "${{ steps.timestamp.outputs.date}}")

    - name: Get timestamp
      id: timestamp
      run: echo "::set-output name=date::$(date +'%Y-%m-%dT%H-%M-%S-%3NZ')"

I should update

        application_name: APP-NAME
        environment_name: ENV-NAME

in .github/workflows/php.yml after I create application

TODO

In S3 I give EC2 S3fullaccess and I should limit it.
Using AWS command line to deploy.

Notes

I can install npm by

commands:
  01enable_epel:
    command: sudo amazon-linux-extras install epel
  02npm_install:
    command: sudo yum -y --enablerepo=epel install nodejs npm

and It works but I see that the project already work on it and add it to package.json for setting up ssl I can go to AWS Certificate Manager and Provision certificates. and then use this certificate in beanstalk loadbalancer for setting up ssl. I have .ir domain name and I try to use it but AWS do not send email and show error. I do not have .com domain now to show setting up ssl.
