What is Continuous Delivery & Drone
Drone is a self-service Continuous Delivery platform that helps to automate software development and delivery processes. But what does this mean, and why is it important?
Continuous Delivery Explained
Continuous Delivery (CD) is a software development practice where code changes are automatically built, tested, and prepared for a release to production. It expands upon Continuous Integration by deploying all code changes to a testing environment and/or a production environment after the build stage.
echo 'This is your code.' > code.txt
echo 'This is your code on Continuous Delivery.' > code-on-cd.txt
diff -u code.txt code-on-cd.txt
# Output:
# --- code.txt
# +++ code-on-cd.txt
# @@ -1 +1 @@
# -This is your code.
# +This is your code on Continuous Delivery.
The above example demonstrates the concept of Continuous Delivery. Your code is continuously updated, tested, and prepared for deployment, just like how the text file code-on-cd.txt
is continuously updated from code.txt
.
The Importance of Drone in Continuous Delivery
In the realm of Continuous Delivery, Drone plays a crucial role. It provides a self-service platform that integrates with your source code management system, automatically triggering the build, test, and deployment processes whenever code is pushed to the repository.
echo 'Push code changes.' > push-code.txt
echo 'Trigger Drone.' > trigger-drone.txt
echo 'Build, test, and deploy.' > build-test-deploy.txt
cat push-code.txt trigger-drone.txt build-test-deploy.txt
# Output:
# Push code changes.
# Trigger Drone.
# Build, test, and deploy.
The above example illustrates the workflow of Drone in Continuous Delivery. When you push code changes, Drone is triggered and starts the build, test, and deployment processes.
Benefits of Using Drone
Drone provides several benefits in the software delivery process, including:
- Automation: Drone automates the build, test, and deployment processes, reducing the risk of human errors and increasing efficiency.
- Self-Service: Drone provides a self-service platform where developers can define and manage their build pipelines.
- Integration: Drone integrates with popular source code management systems like GitHub, GitLab, and Bitbucket.
- Scalability: Drone can scale to support large projects and teams.
In conclusion, Drone is an essential tool for implementing Continuous Delivery, providing automation, self-service, integration, and scalability in the software delivery process.

echo 'Deploying with Drone in a DevOps pipeline.' > devops.txt
cat devops.txt
# Output:
# Deploying with Drone in a DevOps pipeline.
The above example represents how Drone can be part of a larger DevOps pipeline, automating the deployment process.
Drone in Microservices Architecture
In a microservices architecture, Drone can be used to automate the delivery of each service independently. This allows for faster, more reliable deployments and ensures each service is tested and deployed in isolation.
echo 'Deploying microservices with Drone.' > microservices.txt
cat microservices.txt
# Output:
# Deploying microservices with Drone.
The above example demonstrates the role of Drone in deploying microservices, providing isolated, independent deployments for each service.
