Container CI CD Pipelines Cheat Sheet

Container CI/CD pipelines automate the entire lifecycle of containerized applications—from building images to deploying them across environments—while embedding security, testing, and quality gates at every step. These pipelines are the backbone of modern cloud-native development, enabling teams to ship updates rapidly without sacrificing reliability or security. A well-designed pipeline integrates build optimization, vulnerability scanning, image promotion, and GitOps workflows to create a seamless path from source code to production. The key distinction from traditional CI/CD lies in the immutable, portable nature of containers: you build once, test thoroughly, and deploy the same artifact everywhere, ensuring consistency across environments while minimizing configuration drift.

Table 1: Container Build Strategies

Strategy	Example	Description
Multi-stage builds	`FROM golang:1.21 AS builder` `WORKDIR /app` `COPY . .` `RUN go build -o app` `FROM alpine:3.19` `COPY --from=builder /app/app .`	• Separates build environment from runtime • drastically reduces final image size by copying only compiled artifacts to a minimal base image.
Layer caching	`COPY package*.json ./` `RUN npm install` `COPY . .`	• Orders Dockerfile instructions to cache expensive operations • placing dependency installation before source code changes speeds up rebuilds.
Build context optimization	`.dockerignore:` `node_modules` `*.log` `.git`	• Excludes unnecessary files from build context using `.dockerignore` • reduces context size and upload time to build daemon.
BuildKit caching	`docker buildx build --cache-from=type=registry,ref=myrepo/cache --cache-to=type=registry,ref=myrepo/cache .`	• Uses remote cache backends to share layers across builds and runners • enables persistent caching in CI environments where local cache is ephemeral.
Parallel stage execution	`FROM base AS deps` `FROM base AS test` `FROM deps AS prod`	• Runs independent build stages concurrently • reduces total build time by parallelizing non-dependent operations.
