Docker containers production Africa : 2026

Docker / containers = standard packaging app 2026. Production : multi-stage builds + scanning + registry + OCI compliance. Africa adoption forte.

TL;DR

- Docker = de facto containers standard.

- Multi-stage builds : images < 100 MB.

- Scan : Trivy, Snyk, Grype.

- Registry : ghcr, ECR, GAR, Harbor.

Multi-stage best practices

• Dockerfile Node.js exemple :

• # Stage 1 : build
• FROM node : 20-alpine AS build
• WORKDIR /app
• COPY package*.json ./
• RUN npm ci
• COPY . .
• RUN npm run build

• # Stage 2 : runtime
• FROM node : 20-alpine
• WORKDIR /app
• COPY --from=build /app/dist ./dist
• COPY --from=build /app/node_modules ./node_modules
• USER node
• EXPOSE 3000
• CMD ["node", "dist/server.js"]

• Image finale : 80-150 MB vs 800+ MB monolithique

Sécurité

Layers :

• Base image minimal (distroless, alpine)
• USER non-root (jamais root prod)
• No secrets dans layers
• Multi-stage (pas de outils build prod)
• SBOM (Software Bill of Materials)
• Image signing (Cosign)
• Pinned versions (no :latest)

Scan tools :

• Trivy : open source, rapide
• Snyk : SaaS, base CVE riche
• Grype : Anchore CLI
• Docker Scout : intégré Docker

• CI integration : block PR si CVE high+

Registry options

Public :

• Docker Hub (limites pulls anonymes)
• GHCR : gratuit OSS
• Quay : Red Hat

• Cloud privé :
• AWS ECR
• GCP Artifact Registry
• Azure Container Registry
• Africa Liquid Telecom registry

Self-hosted :

• Harbor (CNCF, recommandé)
• Distribution registry
• JFrog Artifactory enterprise

OCI standard

• OCI = Open Container Initiative :
• Image spec (manifest, layers)
• Runtime spec (runc, containerd, CRI-O)
• Distribution spec (registry API)

Pourquoi compte :

• Portabilité runtimes
• Helm charts OCI
• Artifacts OCI (config, signatures)

FAQ

Q : Docker vs Podman ?

R : Podman daemonless + rootless. Drop-in replacement Docker pour la plupart cas. Compatibilité OCI.

Q : Image size optimal ?

R : <200 MB idéal. distroless = <50 MB pour binaires Go.

Conclusion

Docker containers production Africa 2026 : multi-stage + scan + registry privé = stack mature. Image security + signing + SBOM = standard 2026. Adoption universelle, K8s ready.
