[BUG] Docker build fails due to Node version mismatch with engines requirement

[Harsh16gupta]

Describe the bug.

The Docker build fails because the Node.js version used in the Dockerfile does not satisfy the engines requirement defined in package.json.

The project requires:
node >= 24.11
npm >= 11.5.1

However, the Dockerfile currently uses an older Node version, which causes npm ci to fail with an EBADENGINE error during the Docker build.

Expected behavior

The Docker build should use a Node.js version that satisfies the engines requirement so that npm ci completes successfully without errors.

Screenshots

How to Reproduce

1. Clone the asyncapi/generator repository.
2. Build the Docker image using the existing Dockerfile.
3. During the build process, npm ci fails with an EBADENGINE error due to an unsupported Node.js version.

The Docker build fails because the Dockerfile uses Node.js 18, but the project now requires Node.js >=24.11 and npm >=11.5.1 as specified in package.json. This causes the npm ci step to throw an EBADENGINE error.

This has already been fixed in a recent PR: the Docker base image was updated to Node 24, which satisfies the engines requirement and resolves the build failure. You can update your Dockerfile by changing the base image to node:24-alpine (or a compatible 24.x variant). After this change, the build should succeed without manual npm upgrades or workarounds. See the details and example in the merged PR "fix(docker): align Node version with engines requirement".

If you want to ensure npm is always at least 11.5.1, you can add a line like RUN npm install -g npm@11.5.1 after the FROM statement, but the official Node 24 images should already include a compatible npm version.

Let me know if you need a sample Dockerfile snippet!
