Current CI/CD Status
The project does not currently have a CI/CD deployment configuration set up. To implement CI/CD, consider the following next steps:
Next Steps for CI/CD Setup
Choose a CI/CD Tool: Select a CI/CD tool that integrates well with Docker and your version control system. Common options include GitHub Actions, GitLab CI, CircleCI, and Jenkins.
Create Configuration Files: Depending on the CI/CD tool chosen, create the respective configuration files to define the build and deployment pipeline. Below are examples for GitHub Actions and GitLab CI.
Example: GitHub Actions Configuration
Create a file named .github/workflows/ci.yml:
name: CI Pipeline
on:
push:
branches:
- main
pull_request:
branches:
- main
jobs:
build:
runs-on: ubuntu-latest
steps:
- name: Check out code
uses: actions/checkout@v2
- name: Set up Go
uses: actions/setup-go@v2
with:
go-version: '1.18'
- name: Build with Makefile
run: make build
- name: Run Tests
run: make test
- name: Lint Code
run: make lint
- name: Build Docker Image
run: docker build -t my-app .
- name: Deploy
run: |
echo "Deploy to your environment here"
Example: GitLab CI Configuration
Create a file named .gitlab-ci.yml:
image: golang:1.18
stages:
- build
- test
- lint
- deploy
build:
stage: build
script:
- make build
test:
stage: test
script:
- make test
lint:
stage: lint
script:
- make lint
deploy:
stage: deploy
script:
- echo "Deploy your application here"
Docker Dependencies in CI/CD
Make sure to leverage the Docker capabilities during the CI/CD process. Build Docker images efficiently by utilizing caching strategies in the Dockerfile. The following example utilizes several build stages:
FROM golang:1.18 as build
WORKDIR /app
COPY go.mod go.sum ./
RUN go mod download
COPY . .
RUN go build -o my-app .
FROM alpine:latest
WORKDIR /app
COPY --from=build /app/my-app .
ENTRYPOINT ["./my-app"]
Kubernetes and Docker Compose
If deploying to Kubernetes or a Docker Compose setup, additional steps are required. Be sure to integrate the Docker Compose file in your deployment scripts.
Example Docker Compose Command in CI/CD
In your CI/CD configuration, you might want to use Docker Compose to manage multi-container applications. For example:
- name: Run Docker Compose
run: |
docker-compose up -d
# Add additional commands to run tests or health checks
Conclusion
Following the steps outlined, one can set up a CI/CD pipeline tailored to integrate with the provided Docker infrastructure. The key is to ensure that the steps in the CI/CD configuration align with the services defined in the docker-compose.yml and follow best practices for Docker builds and releases.
