Hire Docker Container Experts

Hire Expert Docker Engineers

Deploying your application means a checklist and a held breath, or it only runs on one person's laptop. We containerise it, monoliths included, so builds repeat and a new developer does not lose days to set-up. It is usually a bounded job, so you may not need a monthly engineer, and we will tell you if not.

Monoliths welcome
Local files, hard-coded settings and scheduled jobs get found first
Kubernetes only if you need it
A few services run fine on Compose or a managed container service

What a Docker engineer does to your application

Writing a Dockerfile takes an hour. Making an application behave well in a container, with no local disk and settings from outside, is the real job, and that often means changing the application slightly.

Finds what assumes one server

Uploads written to local disk, settings hard-coded for one machine, cron jobs, sessions in files, and logs written to a file nobody will read. Each one needs a home outside the container before it can be safely replaced.

Builds images people can trust

Multi-stage builds, pinned base images, a non-root user, no secrets in layers, and an image scan in the CI pipeline. Smaller images also mean quicker deploys, and fewer packages to patch when a vulnerability appears.

Picks a sensible way to run it

Docker Compose for local work and small sites, a managed container service for most production, and Kubernetes when you have many services and people to run a cluster. Migrations and rollbacks get planned in as well.

How to judge a Docker engineer in one call

  • Ask where uploaded files and sessions should go, and why not in the container
  • Ask how they would run database migrations during a rolling deploy
  • Ask how they keep secrets out of an image, including its build history
  • Ask whether you need Kubernetes. Listen for questions about your team, not a quick yes
  • Ask them to reduce a slow build. Layer order and a .dockerignore file should come up

Choose your developer level

Compare Docker developer levels, experience, and monthly rates (160 h per month, retainer discount; USD, invoiced in USD, GBP, EUR or INR). Every level is available on hourly, monthly, or dedicated-team engagements; short pieces of work are from $20/h.

How a Docker engagement runs

Your developer is part of our engineering team in India with 3โ€“5 hours of overlap with the UK and Europe; US calls by appointment.

Hourly is often enough

Containerising one application is usually bounded work. Hourly billing may suit you better than a monthly developer, who makes sense only when deployment work is continuous.

What to send us

Your stack, how you deploy today, where it runs, and anything that writes to local disk. After a call we confirm who is free and a start date.

About our proof

Most of our work is delivered under NDA, so many projects cannot be named. We have no public Docker case study, so ask us on the call about work like yours.

It does not fix the app

Containers make deployment repeatable. They do not make slow code quick or a bad schema good. If those are the real problem, we will tell you, and suggest a developer for that instead.

Frequently Asked Questions

Common questions about hiring Docker developers from itmarkerz.

Can you help containerize our legacy applications?
Usually, including monoliths. The awkward parts are files written to local disk, settings hard-coded for one server and scheduled jobs, so we find those first. Containers make deployment repeatable, but they don't fix the code inside them.
Do we need Kubernetes?
Often not. For a few services, Docker Compose or a managed container service is simpler and cheaper to run. Kubernetes earns its cost when you have many services and people to look after the cluster.
Is a full-time Docker engineer worth it?
Often not. Containerising an application is usually a bounded job, so hourly work may suit you better than a monthly developer. A dedicated engineer makes sense when deployment work is continuous.
How do you keep images small and safe?
With multi-stage builds, pinned base images, a non-root user, no secrets in layers and an image scan in the CI pipeline. The result depends on your application, so we check the images you build today first.
