GIT PUSH

To start a CI/CD pipeline and run automated tests after modifying the code in a cloned repository, the appropriate command is git push. When a developer pushes the changes to the remote repository, it triggers the CI/CD pipeline configured in the repository. Here are the steps:

Clone the repository from GitLab.

Make the necessary code modifications.

Use git commit to commit the changes locally.

Use git push to push the committed changes to the remote repository.

Pushing the changes to the remote repository initiates the CI/CD pipeline, which typically includes steps like building the application, running tests, and deploying the application if tests pass.

One of the key principles of a code review process is to ensure that naming standards are consistent. This helps maintain code readability, understandability, and maintainability. Consistent naming conventions reduce the cognitive load for developers when reading and understanding the code, making it easier to manage and less prone to errors.

In the given Dockerfile, the WORKDIR /app command sets the working directory for any subsequent commands to /app. This means that any commands following this line will be executed within the /app directory inside the Docker container. The COPY . . command copies the contents of the current directory on the host machine to the /app directory in the container. Finally, the CMD ["node", "source/server.js"] command specifies the command to run when the container starts, which in this case is node source/server.js.

To provide an encrypted connection when using API keys to communicate with a REST API, the connection must use HTTPS. The curl command with the -X GET option and an HTTPS URL ensures that the communication is encrypted, protecting the API key and data in transit.

A hybrid cloud deployment model is the best choice for addressing the issue of application crashes due to spikes in user access while allowing for future growth and preserving existing investments. Hybrid cloud integrates on-premises data centers (private cloud) with public cloud services, providing scalability and flexibility. This model allows the company to handle peak loads by offloading traffic to the public cloud while maintaining critical applications and data in the private cloud.

Simplifying the wording: Webhook enables the app to ( push or receive real time) . The clients Webhooks enable applications to receive real-time data by providing a mechanism for one application to send data to another as soon as an event happens. This is done through HTTP callbacks, where an event in the source system triggers an HTTP POST request to a predefined URL in the destination system. This allows the destination system to process the data immediately, ensuring real-time updates.
