# envstamp

Make docker containers easily configurable with environment variables

![](assets/envstamp.png)

This was built to make it easier to modify config files in a docker

image using environment variables

## Install

```sh

sudo curl -L -o /bin/envstamp https://github.com/jamrizzi/envstamp/releases/download/v0.2.0/envstamp

sudo chmod +x /bin/envstamp

```

## Build

```sh

git clone https://github.com/jamrizzi/envstamp.git

make build

```

## Usage

Assume you have the following template at `/my/custom/template.txt`

```

Hello ${WOLRD}

```

Run the following . . .

```sh

export WOLRD=galaxy

envstamp /my/custom/template.txt

```

All environment variables have been replaced in `/my/custom/template.txt`

```sh

cat /my/custom/template.txt

# Hello galaxy

```

To set a default value when an environment variable does not exist, use the following syntax

```

Hello ${WORLD:universe}

```
