• [x] Create a snapshot of the current production Lightsail instance:

  • Go to the AWS Lightsail console and select the instance you want to create a snapshot for.
  • Click on "Create snapshot" button.
  • Give a name to the snapshot and click on "Create snapshot" button.

• [x] Create a new instance from the snapshot:

  • Go to the Lightsail console and click on "Snapshots" from the left-hand menu.
  • Select the snapshot you just created and click on "Create instance" button.
  • Choose the instance plan, region and other settings as per your requirements.

• [x] Start the new instance:

  • Once the instance is created, click on "Start" button to start the instance.

• [x] Restart pm2 and refresh it to reflect the changes (URL and PORT) made to the environment variable:

  • Run the following command to restart pm2: sudo LOCAL_BASE_URL='https://conf-gpt.zenuml.com' DATABASE_URL='postgres://xxxx' PORT=8080 NODE_ENV=production pm2 restart app --update-env
  • Run sudo pm2 save to save the effect
  • Run sudo reboot to verify the env variables are persistent

• [x] Enable TLS with self-signed certificate using Nginx to terminate TLS:

  • Install Nginx on the new instance by running the following commands:

    sudo apt update
    sudo apt install nginx

  • Generate a self-signed SSL/TLS certificate

    sudo openssl req -x509 -nodes -days 365 -newkey rsa:2048 -keyout /etc/ssl/private/nginx-selfsigned.key -out /etc/ssl/certs/nginx-selfsigned.crt

  • Configure Nginx to use the certificate and terminate TLS by creating a new configuration file in the /etc/nginx/sites-available directory. Here is an example configuration (see comment)
  • Create a symbolic link to enable the new configuration file by running the following command: sudo ln -s /etc/nginx/sites-available/myapp.conf /etc/nginx/sites-enabled/
  • Restart Nginx by running the following command: sudo systemctl restart nginx

• [x] Attach a static IP to the new instance:

  • Go to the Lightsail console and select the new instance.
  • Click on "Networking" from the left-hand menu.
  • Click on "Create static IP" button and follow the instructions to create a new static IP.
  • Once the static IP is created, click on "Attach" button and select the new instance to attach the static IP to it.

• [x] Create an IPv4 DNS record pointing to the Lightsail instance:

  • Go to your domain registrar's website and log in to your account.
  • Find the DNS settings for your domain and create a new DNS record.
  • Set the type to "A".
  • Set the name to the subdomain you want to use (e.g. "conf-gpt").
  • Set the value to the static IP address you just created.
  • Save the changes.

• [x] Create an IPv6 DNS record pointing to the Lightsail instance:

  • Go to your domain registrar's website and log in to your account.
  • Find the DNS settings for your domain and create a new DNS record.
  • Set the type to "AAAA".
  • Set the name to the subdomain you want to use (e.g. "conf-gpt").
  • Set the value to the IPv6 address of the Lightsail instance.
  • Save the changes.

• [x] Test the new domain:

  • Open a web browser and go to zenuml-stg.atlassian.net.
  • Verify that the application is accessible and functioning correctly.

• [x] Wait for the application is approved before switching it in list
