Ignore File Generator

Q: Where should I place .gitignore and .dockerignore

For Git, place .gitignore at the repository root so rules apply to the whole project (you can also add additional .gitignore files in subfolders for tighter scope). For Docker, place .dockerignore in the build context you run docker build from — typically next to your Dockerfile — so Docker does not send unnecessary files to the daemon.

Q: Can I use multiple ignore files

Yes. Git supports multiple .gitignore files (for example per subdirectory) and also machine-wide global ignores. Docker supports a single .dockerignore per build context, so keep it close to your Dockerfile and aligned with what you COPY into the image.

Q: Will this generator upload my code or repository

No. The UI does not ask you to paste source code or file paths. The server only receives a template id and a template type and then returns a plain-text ignore file for download.

Q: Why do ignored files still show up

If a file is already tracked, adding it to .gitignore will not remove it from Git history. You need to untrack it (for example: git rm --cached path/to/file) and then commit. Also check for more specific ignore rules, negations (!), and whether the file is outside the directory scope of a subfolder .gitignore.

Generate clean .gitignore and .dockerignore files for your stack in seconds — search templates and download a ready-to-use ignore file.

Ignore file generator for Git and Docker projects

Ignore files are small text files with a big impact: they tell Git and Docker which files should not be committed or shipped to a build context. The result is cleaner diffs, faster reviews, fewer “works on my machine” artifacts, and smaller Docker builds.

With Packly Ignore File Generator you pick the type (.gitignore or .dockerignore), search a curated template for your stack (for example .NET, Node.js, Python, Java, Go), and download a ready-to-use file in seconds. You can then commit it to your repo and adjust rules as your project evolves.

Tip: place .gitignore at your repository root and commit it. Place .dockerignore next to your Dockerfile (or wherever your build context starts) to avoid sending unnecessary files to Docker.

Why ignore files matter

A good ignore file is one of the simplest ways to improve repository hygiene. It reduces noise in pull requests, prevents accidental commits, and keeps Docker builds focused on what actually matters.

Cleaner commits

Ignore build outputs, caches, and generated files so pull requests focus on meaningful source changes — not churn from your toolchain.

Fewer merge conflicts

Avoid committing machine-specific folders and IDE artifacts that differ across developers, OSes, and CI runners.

Safer repositories

Reduce the risk of leaks by ignoring common environment files and local-only configs (for example .env files or local settings) that may contain secrets.

Faster setup

Start from a curated baseline for your stack, then fine-tune as your project grows — without reinventing ignore patterns every time.

How it works

Generate an ignore file in seconds, then keep it as a living part of your project: commit it to Git, and use .dockerignore to control what gets sent to Docker during builds.

Select the type (Git or Docker) and search by language, framework, or tool (for example .NET, Node.js, Python).
Choose the closest match for your stack.
Click Generate to download the file as .gitignore or .dockerignore (plain text).
Place it in the correct location, commit it, and review rules when you add new tooling or build steps.

Best practices and practical tips

The goal is consistency: ignore what is reproducible (build outputs, caches) and keep what is required to build from scratch. Revisit rules when your stack changes.

Rules that scale

Ignore build outputs and cache folders early (bin/, obj/, dist/, node_modules/) before they show up in commits.
Do not ignore source files required to build from scratch (for example migrations or generated code that is part of your release process).
Ignore local environment files that can contain secrets (.env, local settings) and prefer secret managers in CI/CD.
Use comments to document why a rule exists so future contributors understand the intent.
Review ignore rules when you add new tooling, switch frameworks, or introduce a new build step — especially for Docker builds.

Small example

Example rules you can adapt for many projects:

# Build outputs
bin/
obj/
dist/

# Logs
*.log

# Environment
.env

Frequently asked questions

Answers to common questions about .gitignore and .dockerignore usage, practical troubleshooting steps, and concise recommendations to keep repositories and Docker builds small, secure, and easy to maintain.

Place .gitignore at the repository root so rules apply project-wide; use additional .gitignore files in subdirectories only when you need folder-scoped rules. For Docker, place .dockerignore in the build context (typically next to the Dockerfile) so Docker does not send unnecessary files (node_modules, build artifacts, logs) to the daemon during docker build. Correct placement reduces image size, speeds up builds, and prevents accidental commits of local or sensitive files.

Adding a pattern to .gitignore does not untrack files already committed. To stop tracking a file while keeping it on disk, run: git rm --cached path/to/file, then commit. For folders: git rm -r --cached node_modules. After untracking, the .gitignore rule prevents those files from being re-added. For user-level ignores, configure a global excludes file with: git config --global core.excludesfile ~/.gitignore_global.

No. The Ignore File Generator only accepts a template id and a template type and returns a plain-text ignore file for download. You are not asked to paste source code, file listings, or repository paths. The server validates template ids and serves pre-curated templates, so no project content is uploaded or stored by this tool.

Common causes: the .dockerignore does not exclude the exact paths your Dockerfile copies (check COPY and ADD instructions), or the build context is set to a parent folder that includes large assets. Fixes: ensure .dockerignore is in the build context root (next to the Dockerfile); explicitly exclude large folders like node_modules/, dist/, .git/, and logs/; run docker build from the smallest appropriate directory; and use multi-stage builds to avoid copying dev dependencies into the final image.

Security and privacy

This tool is designed to be safe by default: you do not paste source code, and the server only needs a template id and type to return an ignore file.

No repository contents are uploaded: the UI does not ask for file lists, paths, or code snippets.
The server validates template type and template id against a known list before reading any template file.
The UI POST request is protected with an anti-forgery token to reduce CSRF risk.
The response is a plain-text download intended to be saved as .gitignore or .dockerignore and then reviewed and committed by you.
