To create a Cloud Storage bucket for storing CodeIgniter application files on Google Cloud, follow these steps:

1. Login to the Google Cloud Console: https://console.cloud.google.com/
2. Create a new project or select an existing project.
3. Click on the "Navigation Menu" ☰ on the top-left corner of the console and go to "Storage > Browser" under the "Storage" section.
4. Click on the "Create bucket" button.
5. Enter a unique name for your bucket.
6. Choose the default storage class for your bucket. (Standard, Nearline, Coldline, Archive)
7. Select a location where you want your data to be stored.
8. Select the default access control for your bucket. (Fine-grained or Uniform)
9. Click the "Create" button to create the bucket.

Once the bucket is created, you can now use it to store your CodeIgniter application files. You can upload your files to the bucket using the Cloud Console UI, Google Cloud SDK, or any other compatible tools.

How to choose the appropriate virtual machine size for running CodeIgniter on Google Cloud?

To choose the appropriate virtual machine size for running CodeIgniter on Google Cloud, you should consider the following factors:

1. Traffic and Workload: Estimate the expected traffic to your website and the workload it will generate. Higher traffic and workload may require a larger machine size.
2. Application Requirements: Evaluate the specific requirements of your CodeIgniter application. Consider factors such as the number of concurrent users and the amount of data processing required. This will help determine the necessary CPU and memory resources.
3. Scalability: Determine if your application needs to scale easily to handle increased traffic or workload. Google Cloud offers auto-scaling capabilities, so consider if you will need this feature and choose a machine type accordingly.
4. Performance Monitoring: Monitor the performance of your application to analyze its resource usage. Google Cloud provides monitoring tools like Stackdriver that can help you understand CPU usage, memory usage, and other metrics, allowing you to choose the appropriate machine size.
5. Cost Considerations: Determine your budget and compare the costs of different machine types. Higher-end machine types come with more resources but may be more expensive. Consider cost optimization techniques like utilizing preemptible instances or applying discounts for long-term usage.

Ultimately, it is recommended to start with a conservative machine size and monitor the performance of your application. You can then scale up or down as needed based on real-time usage data.

How to connect to a VM instance using SSH on Google Cloud?

To connect to a VM instance using SSH on Google Cloud, you can follow these steps:

1. Open the Google Cloud Console: Go to https://console.cloud.google.com/ and sign in to your Google Cloud account.
2. Navigate to the VM instances page: Select your project from the project drop-down list in the top-left corner of the console. Then, go to the "Compute Engine" > "VM instances" page.
3. Locate your VM instance: Find and select the VM instance you want to connect to.
4. Click the "SSH" button: A web-based SSH session will open in a new browser tab. This method requires a supported web browser (Chrome recommended).
5. (Optional) Configure the SSH session: In the SSH session window, you can perform certain configurations such as port forwarding and adding SSH keys.
6. Begin the SSH session: The SSH session starts automatically, and you will be connected to your VM instance through the command line.

You can also use the command-line tool gcloud to connect via SSH. To do this, open a terminal or command prompt and use the following command:

1

gcloud compute ssh [INSTANCE_NAME]

Replace [INSTANCE_NAME] with the name of your VM instance.

Remember to have the necessary IAM permissions and the appropriate firewall rules configured to allow SSH access to your VM instance.

How to setup SSL/TLS certificates on Google Cloud for secure CodeIgniter deployment?

To setup SSL/TLS certificates for secure CodeIgniter deployment on Google Cloud, follow these steps:

1. Purchase a domain name and verify the ownership.
2. Log in to the Google Cloud Console.
3. Create a new project if you don't have one. Navigate to the project's Dashboard.
4. Enable the necessary APIs: "Google Compute Engine API" and "Google Cloud DNS API".
5. Set up the Compute Engine instance: Go to the "Compute Engine" section and click on "Create Instance". Select the appropriate region and zone. Provide a name for the instance and select the desired machine configuration. Under "Boot disk", select an operating system and click on "Change" to choose a boot disk image. Customize additional settings as needed and create the instance.
6. Configure DNS settings for the domain: Go to the "Network Services" -> "Cloud DNS" section. Create a new managed zone. Enter your domain name and choose a DNS name. Save the changes. Create DNS records for the domain that points to your instance's IP.
7. Install Certbot on your instance: SSH into your instance using a web-based SSH tool or any other SSH client. Run the following commands to install Certbot: sudo apt-get update sudo apt-get install certbot
8. Request and obtain an SSL/TLS certificate: Run the following command to generate the certificate: sudo certbot certonly --manual Follow the prompts to enter your email address, agree to the terms of service, and verify the domain ownership. Certbot will provide instructions to create a DNS TXT record. Follow those instructions to add the TXT record to your Cloud DNS. Once the TXT record is added, run the command again to verify DNS and obtain the certificate.
9. Configure CodeIgniter to use SSL/TLS: Open your CodeIgniter project's configuration file (config.php) and update the base_url parameter to use https:// instead of http://.
10. Enable HTTPS redirection:

• Install Apache's mod_rewrite module (if not already installed): sudo a2enmod rewrite
• Edit the Apache config file: sudo nano /etc/apache2/sites-available/000-default.conf
• Inside the tag, add the following lines to redirect HTTP requests to HTTPS: RewriteEngine On RewriteCond %{HTTPS} off RewriteRule ^(.*)$ https://%{HTTP_HOST}%{REQUEST_URI} [R=301,L]
• Save the changes and restart Apache: sudo service apache2 restart

1. Test the setup: Access your CodeIgniter application using the HTTPS version of your domain (e.g., https://your-domain.com). Verify that the SSL/TLS certificate is properly installed and the website loads securely.

By following these steps, you will be able to set up SSL/TLS certificates on Google Cloud for secure CodeIgniter deployment.
