Drone CI is an open-source continuous integration and continuous delivery (CI/CD) platform that enables developers to automate the building, testing, and deployment of their applications.
While Drone CI offers an intuitive interface and straightforward configuration, there are many tips and hacks that can help you get the most out of this powerful tool. In this tutorial, we'll explore some advanced tips and tricks to enhance your Drone CI experience.
Before diving into the tips and hacks, make sure you have the following prerequisites:
- A working installation of Drone CI.
- Familiarity with basic Drone CI concepts, such as pipelines, steps, and plugins.
Tip 1: Conditional Pipeline Execution
You can set up conditional execution of pipeline steps using environment variables. For example, you may want to run certain steps only when a specific branch is pushed. Here's how to do it:
kind: pipeline type: docker name: default steps: - name: build image: golang commands: - go build when: branch: exclude: [feature/*] - name: deploy image: alpine commands: - echo "Deploying..." when: branch: include: [release/*]
In this example, the
build step will only execute when the branch does not match any
feature/* pattern, while the
deploy step will only execute when the branch matches a
Tip 2: Parallel Steps
Drone CI allows you to run steps in parallel, which can significantly speed up your builds. Use the
depends_on attribute to specify which steps can run concurrently. Here's an example:
kind: pipeline type: docker name: default steps: - name: test image: node commands: - npm test - name: build image: node commands: - npm build - name: deploy image: alpine commands: - echo "Deploying..." depends_on: - test - build
In this configuration, the
build steps can run in parallel before the
deploy step begins.
Hack 1: Secrets Management
To securely store sensitive data such as API keys and passwords, use Drone CI's secrets management feature.
Define secrets in your repository settings, and then reference them in your pipeline configuration:
kind: pipeline type: docker name: default secrets: - source: my_secret target: MY_SECRET steps: - name: deploy image: alpine commands: - echo "Deploying with secret: $MY_SECRET"
This ensures that sensitive information is not exposed in your repository configuration.
Hack 2: Custom Plugins
Drone CI allows you to create and use custom plugins to extend its functionality. You can write custom plugins in Go, Python, or any language that supports HTTP.
For example, you can create a custom plugin to interact with a unique deployment platform or perform a specialized task.
Hack 3: Caching
To speed up your builds further, consider using the caching feature to store dependencies between pipeline runs.
For example, you can cache your Node.js
node_modules directory to avoid downloading dependencies on every build.
kind: pipeline type: docker name: default steps: - name: cache image: alpine commands: - mkdir -p /root/.cache volumes: - /root/.cache
By adding a
cache step like the one above, you can cache directories and files that you want to persist between builds.
Hack 4: Self-hosted Runners
Drone CI supports self-hosted runners, allowing you to use your own infrastructure for running build jobs. This is useful for handling complex or resource-intensive builds.
Drone CI is a versatile CI/CD platform that offers a range of features and extensibility options. By mastering these tips and hacks, you can optimize your CI/CD pipelines, improve security, and tailor your builds to your specific needs.
