# Example version script.
# Please choose one version or create your own

# Node.js: grep the version from a package.json file with jq
jq -rM '.version' package.json

# Elixir: grep the version from a mix file
cat mix.exs | grep version | grep '\([0-9]\+\.\?\)\{3\}' -o

# INSTALL
# - copy the files deploy.env, config.env, version.sh and Makefile to your repo
# - replace the vars in deploy.env
# - define the version script

# Build the container
make build

# Build and publish the container
make release

# Publish a container to AWS-ECR.
# This includes the login to the repo
make publish

# Run the container
make run

# Build an run the container
make up

# Stop the running container
make stop

# Build the container with differnt config and deploy file
make cnf=another_config.env dpl=another_deploy.env build

# You have to define the values in {}
APP_NAME=my-super-app
DOCKER_REPO={account-nr}.dkr.ecr.{region}.amazonaws.com
# optional aws-cli options
AWS_CLI_PROFILE={aws-cli-profile}
AWS_CLI_REGION={aws-cli-region}

# Port to run the container 
PORT=4000

# Until here you can define all the individual configurations for your app
