Containerization: Docker
Portable, consistent environments. Includes Image Optimization, Vulnerability Scanning, Environment Parity and 12-Factor Compliance — delivered by IQDigital's…
Containerisation packages your application and its dependencies into a portable unit that runs the same way everywhere. IQDigital builds small, secure Docker images with multi-stage builds, scans them for vulnerabilities before release and follows twelve-factor practices so development, staging and production stay identical.
Who it's for
- Teams fighting "it works on my machine" bugs
- Companies preparing to move to Kubernetes or a container platform
- Organisations that need images scanned for vulnerabilities
What is containerisation?
'It works on my machine' is not a valid excuse. IQDigital uses Containerization (Docker) to package your application and all its dependencies into a single, portable unit. This ensures that your code runs exactly the same way on a developer’s laptop, a testing server, and a production cluster. We eliminate 'environmental drift.'
How we build optimised, secure images
We build optimized 'Docker Images.' We use multi-stage builds to keep image sizes small (Alpine Linux base), improving security and deployment speed. We scan images for vulnerabilities (CVEs) before they ever reach production. We decouple the application from the underlying OS, allowing for easy updates and patching.
What the twelve-factor methodology adds
We preach the '12-Factor App' methodology. We configure containers via environment variables, treat backing services as attached resources, and execute apps as stateless processes. Containerization is the fundamental unit of modern cloud architecture, and we ensure your foundation is solid.
What's included
- Image Optimization — Multi-stage builds for lightweight containers.
- Vulnerability Scanning — Automated security checks for images.
- Environment Parity — Consistency across Dev, Stage, and Prod.
- 12-Factor Compliance — Best practices for cloud-native apps.
How an engagement runs
- Diagnose (Week 1) — We find the money before we spend yours.
- Build (2–8 weeks) — Senior engineers. Your stack. Weekly proof.
- Launch (Go-live) — Released against a baseline, not a hope.
- Compound (Ongoing) — The second month should beat the first.
How the work is scoped
- Engagement: Fixed-scope project · optional managed support
Questions about Containerization
What problem does Docker solve?
Environment drift. The same container runs identically on a developer's laptop, a test server and production.
What is a multi-stage build?
A Dockerfile technique that builds the app in one stage and copies only what is needed into a small final image, often on a minimal base such as Alpine Linux — smaller images deploy faster and expose less.
How do you keep images secure?
Images are scanned automatically for known vulnerabilities (CVEs) before they reach production.
What is a twelve-factor app?
A set of practices for cloud-native apps, such as configuration through environment variables, backing services as attached resources and stateless processes.
