1. build

docker build -t nextjs-app .

aws ecr get-login-password --region ap-southeast-1

Then it will come out the password

2. login

docker login -u AWS -p somePassword 123456789012.dkr.ecr.us-east-1.amazonaws.com

3. tag

docker tag nextjs-app:latest 123456789012.dkr.ecr.us-east-1.amazonaws.com/nextjs-app:latest

4. push

docker push 123456789012.dkr.ecr.us-east-1.amazonaws.com/nextjs-app:latest

Below example for docker login stdin with aws get password

aws ecr get-login-password --region ap-southeast-1 | docker login -u AWS --password-stdin 123456789012.dkr.ecr.us-east-1.amazonaws.com

To increase the space on your AWS instance, follow these steps:

1. Check the Available Storage:
Before expanding, verify the disk space:

df -h

2. Identify the Volume:
Find the attached volumes for your EC2 instance:

Go to the EC2 Console.
Under Elastic Block Store (EBS), select Volumes.
Identify the volume attached to your instance.

3. Modify the EBS Volume:
Select the volume you want to expand.
Click on Actions → Modify Volume.
Increase the size of the volume (e.g., from 8 GB to 20 GB).
Click Modify.

4. Extend the Partition on the EC2 Instance:
After the volume is resized, you'll need to extend the file system to use the new space.

For ext4 file system:
Verify the volume size:

lsblk

Make sure the resized volume reflects the correct size.
Extend the file system:

sudo growpart /dev/nvme0n1 1
sudo resize2fs /dev/nvme0n1p1

For xfs file system:
Extend the file system:

sudo xfs_growfs -d /

5. Verify the Increased Space:
Check the disk space again:

df -h

This process will allow you to increase the disk space without stopping the instance.

To check partition type

lsblk -f

To run multiple PHP versions (8.3 and 7.4) on Ubuntu 24, you can install PHP 7.4 alongside PHP 8.3 and configure PHP-FPM to handle both versions. Here’s a step-by-step guide:

Step 1: Add PHP 7.4 Repository
First, you need to add the ondrej/php PPA, which allows you to install older PHP versions like 7.4.

sudo apt update
sudo apt install software-properties-common
sudo add-apt-repository ppa:ondrej/php
sudo apt update

Step 2: Install PHP 7.4 and PHP 7.4-FPM
Now, install PHP 7.4 along with its FPM package and any required extensions.

sudo apt install php7.4 php7.4-fpm php7.4-cli php7.4-common php7.4-mysql php7.4-xml php7.4-mbstring php7.4-curl

Step 3: Ensure PHP 8.3 FPM is Installed
Make sure you also have PHP 8.3 FPM installed (if not already):

sudo apt install php8.3-fpm

Step 4: Configure Nginx to Use Different PHP-FPM Versions
Now, you need to modify your Nginx configuration to point to the correct PHP-FPM socket for each site or location.

For PHP 8.3 (default):
In your Nginx config file (e.g., /etc/nginx/sites-available/default), set the fastcgi_pass directive to PHP 8.3:

nginx
Copy code
location ~ .php$ {
fastcgi_pass unix:/run/php/php8.3-fpm.sock;
include fastcgi_params;
}

For PHP 7.4 (for specific locations or sites):
For specific sites or locations where you want to use PHP 7.4, you can point to the PHP 7.4 FPM socket:

location ~ \.php$ {
    fastcgi_pass unix:/run/php/php7.4-fpm.sock;
    include fastcgi_params;
}

Step 5: Enable and Restart PHP-FPM Services
Enable both PHP-FPM services to ensure they start on boot:

sudo systemctl enable php8.3-fpm
sudo systemctl enable php7.4-fpm

Then restart both services:

sudo systemctl restart php8.3-fpm
sudo systemctl restart php7.4-fpm

Step 6: Set PHP 8.3 as the Default CLI Version (Optional)
If you want to keep PHP 8.3 as the default for the CLI, use the update-alternatives command:

sudo update-alternatives --set php /usr/bin/php8.3

To switch to PHP 7.4 for the CLI:

sudo update-alternatives --set php /usr/bin/php7.4

Step 7: Verify Installation
To check the installed versions of PHP-FPM, run:

php -v          # To check the default CLI version
sudo systemctl status php7.4-fpm
sudo systemctl status php8.3-fpm

Conclusion
Now you have both PHP 8.3 and PHP 7.4 running on your Ubuntu 24 system, with PHP 8.3 as the default and the ability to use PHP 7.4 for specific locations or virtual hosts.

CPU - get the i5 14th-gen. If budget constrain, i5 12th-gen pun good CPU. Try not get into seller trap, which they might sell AMD Ryzon or something, as AMD is battery hunger, and AMD have bad history of over-heating. If you are gamer, yes, go for AMD.

RAM - if possible, get 16GB RAM. If budget issue, get 8GB minimum. Do not get below 8GB. Chrome nowdays a little mafia-eating-memory. If possible, get 16GB - comfortable for long run usage, example 5 to 10 Chrome tabs.

HDD - get with SSD drive (which range around 256GB to 512GB. Do not get normal spinning 1TB hard drive (seller might hard-sell you, saying 1TB is much more spacious, but, it is slow) - realistically, in normal work, 256GB or 512GB is good enough (unless you need for video editing or Photoshopping)

Screen size - if need big screen, get 15”. But, it is less portable compared to 14” - In my personal case, I prefer to be highly portable, so I opted for 13”, can do work anywhere.

Kalau boleh, if budget is good, boost up the RAM, 24GB ke.
