Companies Using Docker

Docker Usage Statistics

Docker reads 3,445 domains on our June 2026 rollup, 3,745 in July and 3,788 in August. Three points cannot carry a growth rate, and this movement is coverage rather than adoption. Across the whole crawl, active detections went from 321.0M in June to 352.2M in August, a 9.7% widening of what we can see, and Docker's own line moves by close to the same proportion over the same window. A DNS marker adds a second reason for caution about the shape of this line: the record is published once and left in place, so a domain joins this set when we first resolve it, not when the organisation started paying. Read the three points as three sightings of a mostly static population rather than as a trend. The August figure, 3,788, is the one quoted at the top of this page.

Which Countries Use Docker the Most?

Which countries use Docker the most? The United States holds 1,865 of the 3,449 companies we could place, 54.07%, ahead of the United Kingdom on 297 (8.61%) and Germany on 241 (6.99%). Canada (136, 3.94%) and Australia (129, 3.74%) complete a top five covering 2,668 companies, 77.36%. It thins quickly after that: Netherlands 67 (1.94%), Switzerland 66 (1.91%), Sweden and Norway 46 each (1.33%), India 41 (1.19%), Japan 38 (1.1%), Finland 37 (1.07%), France 36 (1.04%), Belgium 34 (0.99%) and Denmark 33 (0.96%). The fifteen countries listed cover 3,112 companies, 90.23%. Two readings are worth separating. The four Nordic countries together are 162 companies, 4.70%, more than France and Japan combined, which is the usual shape for a paid developer tool. And India at 1.19% is a caution rather than a conclusion: Infosys is third on the named list here, but a verified domain belongs to a headquarters, and it says nothing about where the engineers using the account sit.

Docker Market Share Among Cloud Infrastructure

What is Docker's market share? Docker holds 0.5% of Cloud Infrastructure and ranks 6th in that category, on 3,788 domains. Before using that number, look at what sits above it. Amazon S3 leads on 659,040 domains and 86.13%, then DigitalOcean Spaces on 41,623 (5.44%), Google Cloud Storage on 26,268 (3.43%), Alibaba Cloud on 18,768 (2.45%) and Alibaba Cloud Object Storage on 11,150 (1.46%). Every one of those is object storage, and every one is found by reading asset URLs out of a page we crawled, so a site that serves a single image from a bucket counts. Docker is found by resolving a DNS record that only a paying organisation publishes. Those two surfaces produce numbers that mean different things, and the ratio between them is a share of detected domains, not a share of infrastructure spending, workloads or containers.

Docker Customers by Company Size & Age

What size companies use Docker? The distribution peaks in the middle rather than at either end. 773 of the 3,458 companies that report a headcount, 22.35%, employ 1,001 to 5,000 people, the largest single band, with 51-200 (548, 15.85%) and 201-500 (547, 15.82%) effectively tied behind it. Above 1,000 employees the total is 1,445 companies, 41.79%, of which the 10,001+ band is 443, 12.81%. At the small end, 981 companies, 28.37%, employ 200 or fewer and 433, 12.52%, employ 50 or fewer. Counted on domains instead of companies, 393 of the 3,788, 10.37%, belong to organisations with 8,000 or more employees. One detail shapes the whole curve: verifying a domain is a paid organisation feature, so a solo developer or a ten-person team on free accounts never appears here. The thin small end is a property of the marker, not evidence that small companies do not run containers.

What Industries Use Docker the Most?

Software Development leads at 20.21% of the 3,419 companies with a recorded industry, 691 companies, twice IT Services and IT Consulting in second on 349, 10.21%. Financial Services is close behind on 337, 9.86%. Grouping the labels that describe the same buyer makes the concentration clearer: software development, IT services, technology and internet, computer and network security and computer games come to 1,299 companies, 37.99%. Financial services and insurance together are 479, 14.01%. The twelve labels shown cover 2,105 companies, 61.57%, so close to four in ten of the matched base sit outside them, spread across dozens of other industries. This is a technology-weighted distribution with a heavy regulated-industry second tier, which is what a paid engineering tool looks like when it is bought centrally rather than expensed by a team.

Software firms using Docker are the largest block at 691 companies, 20.21% of the 3,419 with a recorded industry, and they are the least surprising row on the page. The interesting one is underneath. IT Services and IT Consulting takes 349 companies, 10.21%, and that is where the consultancies and systems integrators sit: Infosys, IBM, Capgemini, HP, Verizon and Genpact are all filed there or in the neighbouring Business Consulting and Services label, which adds 61 companies, 1.78%, and holds Accenture, Deloitte and Genpact. A verified domain belonging to an integrator represents an engineering population that builds for other companies, so one row here stands for a very different volume of work than one row in a small software vendor. Banks and insurers using Docker come to 479 companies, 14.01%, across Financial Services (337, 9.86%) and Insurance (142, 4.15%), with HSBC, Morgan Stanley, Itau Unibanco and AXA named below. Health care is thinner than its named members suggest at 74 companies, 2.16%, though Abbott, HCA Healthcare, Optum and Medtronic all appear. Computer Games at 58, 1.7%, and Entertainment Providers at 69, 2.02%, are small but real, and both are industries with large internal build pipelines. One record caveat before reading any of these rows too closely: Bosch is filed under Software Development, which describes one part of an engineering group rather than the whole of it, so a handful of the software rows are conglomerates classified by their most digital division.

Docker Alternatives & Competitors

This table needs reading twice, because nothing in it is a container platform. Cloud Infrastructure is ranked by detected domains, and the rows above Docker are object storage: Amazon S3 on 659,040 domains and 86.13%, DigitalOcean Spaces on 41,623 (5.44%), Google Cloud Storage on 26,268 (3.43%), Alibaba Cloud on 18,768 (2.45%) and Alibaba Cloud Object Storage on 11,150 (1.46%). Those are read from the asset URLs of pages we crawl, a surface nearly every website exposes. Docker is read from DNS, on a record only a paying organisation publishes. A company can run all of these at once, so treat the table as a ranking of category neighbours, not a set of substitutes. The pages measured the way this one is are the ones matched by the same kind of record: IBM Cloud, found by an ibmid= TXT record, and Postman's published API docs. A genuine Docker alternative would need a public footprint to be counted at all, and a container runtime chosen inside a private network does not leave one on the open web, which is a limit of the method rather than a statement about the products.

Docker Customer Migration

There is no switching table here, and the reason is not that the corridors came back empty. They came back with numbers we chose not to publish. The largest was 110 domains recorded as gained from Amazon S3, and that pairing carries no meaning: Amazon S3 is object storage detected from asset URLs on a page, Docker is a container platform detected from a DNS record, and nobody replaces one with the other. A migration table has to pass a same-functional-role test before it is worth printing, and every corridor available on this page failed it, so read this section as a measurement that ran, was checked and was rejected. The churn count underneath explains why there is so little movement to attribute in the first place. 27 domains have dropped Docker since we began tracking in March 2026, 0.71% of the 3,788 counted here. That is not a retention statistic. Nobody returns to their DNS zone to delete a TXT record after cancelling a subscription, so this marker records that an organisation once verified a domain and keeps on recording it. The same caution applies on the other pages matched this way, including IBM Cloud with 8 dropped domains.

Tech Stack of Docker-Powered Websites

Because the marker here is a DNS record, this table is not a picture of what these companies run in production. It is two things laid on top of each other. The first is other verified account markers found the same way: DocuSign on 42.68%, and Atlassian on 77.37%, the highest co-occurrence in this group of pages, cited here rather than shown in the table because we hold no icon for it. Products such as Microsoft 365 and Google Workspace land in that column for the same reason. What the block says is that a company which verified a domain for Docker has usually verified domains for several other vendors too, which is a fact about corporate IT procurement and not about containers. The second layer is the company's public website, because a DNS-matched domain sends the crawler to the homepage: Google Tag Manager 78.34%, Google Analytics 68.89%, Cloudflare 57.63%, Priority Hints 52.66%, Google Font API 43.5%, OneTrust 40.27%, Amazon Web Services 38.81% and Bootstrap 37.38%. That is a marketing site, not a container host. One denominator note: divide any overlap count in this table by its own percentage and the base comes out at about 3,906 domains, the wider set our live crawl currently answers for Docker, so these percentages divide by roughly 3,906 rather than by the 3,788 in the August rollup.
