In today’s fast-paced tech world, automating deployments is essential for maintaining efficiency and reliability. For organizations using HumanGov, a SaaS application, deploying AWS CI/CD tools on Kubernetes can significantly streamline the process. This blog post will guide you through setting up an AWS CodeCommit repository, implementing continuous integration with AWS CodeBuild, defining Kubernetes deployment configurations, and creating Dockerfiles for HumanGov application image building.
Setting Up the AWS CodeCommit Repository
AWS CodeCommit is a secure, scalable, and managed source control service that allows teams to host Git repositories. To get started:
- Create a CodeCommit Repository:
Navigate to the AWS Management Console.
Open the CodeCommit console.
Click on “Create repository” and provide a name and description.
- Clone the Repository:
Use the provided clone URL to clone the repository to your local machine.
git clone <repository-url>
- Push Code to CodeCommit:
Add your HumanGov application code to the repository.
Commit and push the changes:
git add .
git commit -m “Initial commit”
git push origin main
Implementing Continuous Integration with AWS CodeBuild
AWS CodeBuild is a fully managed build service that compiles source code, runs tests, and produces software packages. Here’s how to set it up:
- Create a Build Project:
- Go to the CodeBuild console and click on “Create build project.”
- Configure the project settings, including the source provider as CodeCommit, and select the appropriate repository.
- Define Build Specifications:
Create a buildspec.yml file in the root of your repository. This file tells CodeBuild how to run your build.
version: 0.2
phases:
install:
commands:
– echo Installing dependencies…
– npm install
build:
commands:
– echo Build started on `date`
– npm run build
- Run the Build:
- Start the build process in the CodeBuild console and monitor the progress.
Defining Kubernetes Deployment Configurations
To deploy HumanGov on Kubernetes, you need to define your Kubernetes configurations. This includes creating deployment and service YAML files.
- Deployment YAML:
Create a file named deployment.yaml and define the deployment specifications.
apiVersion: apps/v1
kind: Deployment
metadata:
name: humangov-deployment
spec:
replicas: 3
selector:
matchLabels:
app: humangov
template:
metadata:
labels:
app: humangov
spec:
containers:
– name: humangov-container
image: humangov-image:latest
ports:
– containerPort: 8080
- Service YAML:
Create a file named service.yaml to expose your application.
apiVersion: v1
kind: Service
metadata:
name: humangov-service
spec:
type: LoadBalancer
selector:
app: humangov
ports:
– protocol: TCP
port: 80
targetPort: 8080
Creating Dockerfiles for HumanGov Application Image Building
A Dockerfile is a script that contains a series of instructions on how to build a Docker image.
- Create a Dockerfile:
In the root of your repository, create a Dockerfile and define the build steps.
# Use an official Node.js runtime as a parent image
FROM node:14
# Set the working directory
WORKDIR /app
# Copy package.json and package-lock.json
COPY package*.json ./
# Install dependencies
RUN npm install
# Copy the rest of the application code
COPY . .
# Build the application
RUN npm run build
# Expose the port the app runs on
EXPOSE 8080
# Start the application
CMD [“npm”, “start”]
- Build and Push the Docker Image:
Build the Docker image:
docker build -t humangov-image .
Tag and push the image to a container registry (e.g., Amazon ECR):
docker tag humangov-image:latest <your-ecr-repo-url>:latest
docker push <your-ecr-repo-url>:latest
Conclusion
By following these steps, you can automate the deployment of HumanGov on Kubernetes using AWS CI/CD tools. This setup ensures a streamlined, efficient, and reliable deployment process, allowing your team to focus on developing great features.
