Docker Volume Mount Regex for JavaScript

What this pattern does

This page provides a well-structured, multi-part regular expression for matching docker volume mount, ported and verified for JavaScript. A rigorously tested regex reduces debugging time and protects your application from edge-case failures. The snippet below is ready to drop into your JavaScript project — whether you're validating in an Express middleware, a Next.js API route, or a client-side form.

Javascript Implementation

// Docker Volume Mount
// ReDoS-safe | RegexVault — Dev & Systems > Docker

const dockerVolumeMountRegex = /^\\/?[a-zA-Z0-9._\-\\/]+:\\/?[a-zA-Z0-9._\-\\/]+(?::r[ow])?$/i;

function validateDockerVolumeMount(input: string): boolean {
  return dockerVolumeMountRegex.test(input);
}

// Example
console.log(validateDockerVolumeMount("/host/path:/container/path")); // true

Test Cases

When to use this pattern

This pattern is drawn from the Dev & Systems > Docker category and carries a ReDoS-safe certification. That matters for JavaScript developers because especially critical in long-running Node.js event loops where a ReDoS vulnerability can block the entire process. RegexVault audits patterns against known backtracking attack vectors, ensuring you have the necessary context before using this regex in a high-stakes production environment.

Common Pitfalls

Technical Notes

Formats: named volume (name:/path), bind mount (/host:/container), or anonymous. Mode: ro=read-only, rw=read-write, z/Z=SELinux relabeling. z is shared between containers; Z is private.
