What this page is
This page quotes r/docker's rules as ThreadFox read them on 2026-09-26. The quoted text is the community's; the verdict above is our reading of it. Conditions often decide whether a post fits (a required thread, flair, posting day, account age or karma), and r/docker's current rules on Reddit always win over this page.
Free, for a specific product: a researched Reddit plan by email (communities whose rules fit your post, quoted and dated), or ThreadFox Lite, read-only tools an AI assistant can use to read a community's current rules itself, through your own Chrome (Claude Code: claude mcp add threadfox-lite -- uvx threadfox-lite). For an assistant that also writes and posts within each community's rules, the ThreadFox kit is $49 once.
Want to post here? Get ThreadFox ($49): your AI (Claude Desktop, Claude Code or Codex) reads a community's current rules, writes one post that fits and posts once from your own Chrome. No Claude? We'll post for you ($99 per 30-day campaign). Free: a Reddit launch plan for your product, ThreadFox Lite or the posting checklist by email.

What its rules say about promotion
Promotion and Self-Promotion
Promoting requires **prior mod approval**. - Educational content, tutorials, and open-source tools may be shared if they provide genuine value, but **must be approved by mods in advance**. New projects are no exception. - Job offers, hiring posts, or solicitations for freelance work also require **mod approval**. - Posts offering paid services, tools, or courses require **mod approval**. Not sure if your post qualifies? [Message the mods](https://www.reddit.com/message/compose/?to=/r/docker).
Link Posts Must Include Context
- If you post a link (e.g., blog, tutorial, or GitHub repo), you must include a brief description or summary explaining its relevance. Please [send us your draft via modmail](https://www.reddit.com/message/compose/?to=/r/docker) for pre-approval. - Link posts without context may be removed. Unapproved self-promotional links may be removed.
No Spam or Unsolicited Advertising
- Spam, repetitive posts, or excessive self-promotion without community engagement is prohibited.
What its rules say about AI and bots
Avoid Low-Effort Posts and AI-Generated Content Without Validation
- Posts should provide enough detail for meaningful discussion. - Avoid vague questions like _"Docker isn’t working"_ without specifying your setup or error messages. - Wherever possible, posts and comments should be written in your own words. If you use a translation service, include the original. - AI-generated content must be properly disclosed, including the models and prompts used. Do not share AI-generated solutions that you have not verified. - Unauthorized bot posts are prohibited.
All 11 rules of r/docker
- Be Respectful and Professional
- Harassment, abuse, hate speech, or disrespectful behavior is strictly prohibited. - Discussions should remain professional, especially when disagreements arise. - Stay On-Topic
- All posts and comments must be directly related to Docker, containerization, and related technologies (e.g., Kubernetes, Compose, etc.). - Posts about Custom-Container-Images are generally allowed but make sure you are not violating rule #7 or #3. The Image shared must provide genuine value to the community. - Off-topic content will be removed. - Promotion and Self-Promotion

When asking for help, include as much information as possible. At minimum: - Your Docker version - Operating system - Your `Dockerfile` and docker `compose.yml` content (if relevant) - please use markdown code blocks or code fences - Error logs or outputs We may not be able to support third-party images.

- Ensure your content aligns with Reddit’s global policies regarding harassment, spam, and misinformation. - Moderator Discretion
To ensure this community remains a welcoming and positive space for everyone, moderators may remove comments or posts that we determine to be toxic, unconstructive, disruptive or otherwise harmful to the sub. While we encourage open discussion, we will use our discretion to moderate content that detracts from a healthy community environment. This is not about censorship but about curating a space where everyone feels safe to participate. We do not support brigading of any kind
What the written rules don't show
- Unpublished minimums. Many communities remove posts from new or low-karma accounts through AutoModerator settings that are not on the rules page, often before a moderator sees them.
- Reddit's own filters. Reddit's site-wide spam filters can remove posts from accounts that mostly share links to their own site, in any community.
- The community's norms. Many communities see themselves as peers, not an audience: post where you already take part, and make the post worth reading without the link.
