# envassert

Ensure that the environment variables match

what is requested, or abort.

# DESCRIPTION

**envassert** checks that your runtime environment, as defined

with environment variables, matches with what you want.

You can define your required environment in a file.

Default file is **.envdesc** but you can use any file.

It is advantageous to use **envassert** for example when running

a container. If you check your environment for missing or

wrongly defined environment variables at the beginning of

the container run, your container will fail sooner instead

of in a later point in execution when the variables are needed.

# SYNOPSIS

envassert [options]

Options:

    --help

    --man

    --version

    --break-at-error

    --env-description

## INSTALLATION

### Packaging

[![Packaging status](https://repology.org/badge/vertical-allrepos/env-assert.svg)](https://repology.org/project/env-assert/versions)

### CLI interface without dependencies

The **envassert** command is also available

as self contained executable.

You can download it and run it as it is without

additional installation of CPAN packages.

Of course, you still need Perl, but Perl comes with any

normal Linux installation.

This can be convenient if you want to, for instance,

include **envassert** in a docker container build.

    curl -LSs -o envassert https://raw.githubusercontent.com/mikkoi/env-assert/main/envassert.self-contained

    chmod +x ./envassert
