resolve-yaml

Merge YAML files and resolve relative file paths

I needed a tool to merge docker-compose files. docker-compose config was ill suited, because it skips unsupported options like deploy that are only used by docker stack deploy.

In contrast to existing tools like merge-yaml this tool transforms relative paths, so the paths are still valid in the merged file. Every string element that starts with ./ is considered a path and is transformed relative to the current working directory.

Installation

npm install -g resolve-yaml

Usage

resolve-yaml file1.yaml file2.yaml [...] >out.yaml

Example

resolve-yaml dir1/docker-compose.yml dir2/docker-compose.yaml >out.yaml

dir1/docker-compose.yml

version: '3'
services:
  serviceA:
    build: ./

dir2/docker-compose.yml

version: '3'
services:
  serviceB:
    build: ./subdirectory

out.yml

version: '3'
services:
  serviceA:
    build: ./dir1

  serviceB:
    build: ./dir2/subdirectory
