r/docker
Docker is an open-source project to easily create lightweight, portable, self-sufficient containers from any application. The same container that a developer builds and tests on a laptop can run at scale, in production, on VMs, bare metal, OpenStack clusters, public clouds and more.

r/docker — frequently asked
How many members does r/docker have?
r/docker has 319,978 members as of our most recent crawl on Aug 25. Prowlo re-checks tracked communities on a rolling schedule, so this figure moves rather than sitting frozen at whatever it was when a scraper last ran.
Is r/docker growing?
We don't have 30 days of snapshot history for r/docker yet, so we're not going to invent a growth number. We've been tracking it since Aug 7; the chart fills in as history accumulates.
How active is r/docker?
We don't have a reliable posting-rate sample for r/docker yet. Subscriber count alone is a poor guide to whether a community is active, so treat this one as unverified until the next sample lands.
Can I promote my product in r/docker?
Our read on r/docker is medium promo tolerance. A product mention is fine when it genuinely answers the question asked, and unwelcome when it does not. Always read the sidebar rules before you post; moderator enforcement is the thing that actually decides.
How do I monitor r/docker for mentions?
Hit Watch on this page. Prowlo starts crawling r/docker into your Dataset — every new post indexed and embedded, searchable semantically, queryable by your AI agent over MCP, and able to trigger keyword alerts in Slack. Prowlo is read-only; it never posts on your behalf.
Can my AI agent read r/docker's stats?
Yes. Everything on this page is one MCP tool call away: catalog_get_subreddit returns r/docker's members, growth, promo tolerance and similar communities as typed JSON — free, no credits. Connect your agent to api.prowlo.com/mcp and it can vet the community and start watching it in the same conversation.
