Bash script that runs swagger-editor in docker and waits for signal SIGINT to kill and remove containers

script.bash

main() {
    docker_command="docker run -d -p 80:8080 "

    if [[ $1 != "" ]]; then
        absolute_path=$(realpath "$1")
        dir=$(dirname "$absolute_path")

        docker_command+="-v $dir:/tmp -e SWAGGER_FILE=/tmp/$1 "
    fi

    docker_command+="swaggerapi/swagger-editor"

    container_id=$(eval "$docker_command")

    echo "Listening here: \033[1;34mhttp://localhost\033[0m 🍁"

    (
        trap exit SIGINT
        read -r -d '' _ </dev/tty
    )

    docker kill "$container_id" >/dev/null
    docker rm "$container_id" >/dev/null
}
