container-env

An environment variable management tool for Node.js apps running inside containers

Installation

npm install container-env

or globally:

npm install container-env --global

or run it with npx:

npx container-env

Usage

You need to create a container-env.json file. The cli can help you with this. After the installation it is available by typing container-env or by using the alias cenv.

Create a config file:

container-env init

Answer the questions. All variable names will be transformed to uppercase and spaces will be replaced with underscores ( _ ).

You can then get the configuration read from the env variables like so:

import { getConfig } from "container-env";

const config = getConfig(JSON.parse(fs.readFileSync(path.join(__dirname, "../../container-env.json")).toString()));

The getConfig() function takes one mandatory and one optional parameter: the first one needs to be the configuration object (you just need to read and parse the container-env.json file). You can optionally specify a path where the effective config should be saved.

Helpers

Add variables

Just type

container-env add

Generate run scripts

You can generate a docker-compose.yml or a docker run command by typing

container-env generate compose

or

container-env generate run

The -s flag saves the output to a file in the current working directory.

Just run

container-env help

to display all available commands and their explaination.
