Docker: mercado
Docker is the baseline literacy of modern software work: the container became the unit of code delivery, and 'knows Docker' appears in postings of every profile. We track 12 384 open positions listing Docker, 11 238 of them fresh. For a developer it means Dockerfiles, compose and image debugging; for DevOps — registries, multi-stage builds, image security and runtimes. Docker most often appears next to Kubernetes, AWS and Azure. 36% of the postings allow fully remote work. Below is measured Docker demand from public sources: trend, geography, seniority and the adjacent stack.

Timeline: postings and sources
How many Docker postings appeared each week since Aug 10, and from how many sources. The second line separates market growth from coverage growth: a jump in the week new sources were connected means we started seeing more, not that the market grew.
New postings and active sources per week
Sources over the period: 347
New sources connected: Aug 17 +57 · Aug 24 +31 · Aug 31 +31 · Sep 7 +25 · Sep 14 +19 · Sep 21 +31 · Sep 28 +18 · Oct 5 +17 · Oct 12 +13 · Oct 19 +26
Week = posting first-seen date, all statuses. A posting belongs to the technology by its stack tag; the series starts on 10 Aug 2026 — earlier tags were assigned differently and are not comparable. Sources are distinct collection channels; their names are not published.

Postings in the country, %
Share among postings with a known country; the chart shows the five countries with the most postings over six months. Weeks with fewer than 20 postings with a known country are left blank. A rising share can mean a newly connected source in that country rather than market growth.

Docker is almost never required alone: Kubernetes, AWS and Azure stand next to it — a container makes sense within an orchestration-and-cloud bundle.

Perguntas frequentes
Common questions about Docker on the job market — short answers from the slice.
Is Docker a standalone profession or a supporting skill?
A supporting but mandatory one: 12 384 postings in the slice list Docker across very different roles. A dedicated 'Docker engineer' title barely exists — containers are part of the DevOps, backend, QA-automation and data-engineering profiles.
What level of Docker is expected from a developer?
Write a Dockerfile for your service, build a slim multi-stage image, run an environment with compose, read logs and exec into a container while debugging. Registries, image signing and runtime security belong to DevOps/Platform.
What should I learn after Docker?
The natural ladder: compose → Kubernetes (orchestration), then Helm, one managed cloud cluster and a CI/CD pipeline that builds and publishes images. That is exactly the bundle visible in the adjacent technologies of this slice.
Is Docker still relevant with alternatives growing (Podman, containerd)?
Yes: alternative runtimes are OCI-image compatible, so the skill transfers almost without loss. In postings 'Docker' often means 'containerization in general' — demand for the ability itself keeps growing.
