variables.nomad
job "variables" {
    datacenters = ["dc1"]

    group "variables" {
        task "variables" {
            driver = "docker"
            config {
                image = "my-docker-image:latest"
            }

            env {

            }
        }
    }
}

Loading environment variables from .env file

.env
MY_VARIABLE=test
variables.nomad
job "variables" {
    datacenters = ["dc1"]

    group "variables" {
        task "variables" {
            driver = "docker"
            config {
                image = "my-docker-image:latest"
            }

            template {
                data = file("./.env")
                destination = "secrets/file.env"
                env = true
            }
        }
    }
}

External configuration files

variables.nomad
job "variables" {
    datacenters = ["dc1"]

    group "variables" {
        task "variables" {
            driver = "docker"
            config {
                image = "my-docker-image:latest"

                volumes = [
                    "local/config.yaml:/etc/my-app/config.yaml"
                ]
            }

            template {
                data = file("./config.yaml")
