    someone-yells

    This is a little demo single page webapp build with nodejs + express + pug. It loads an image hosted in s3 and displays the server's IP address and hostname. This demo app is used across multiple repositories to show AWS container services, such as (microservices-ecs-cloudformatio)[https://gitlab.com/henrybravo/microservices-ecs-cloudformation], someone-yells-k8s, helm chart, someone-yells-cdk

    suggested dev environment that runs in a container

    To use the offical node container to develop and build the app, pull the image:

    $ docker pull node

    Start the node container (build on debian jessie) - where we expose port 3000 to localhost so we can preview the app in the browser too

    $ docker run -it -p 3000:3000 node bash

    In the container

    root@fb12900d0e7d:/# apt-get update -y && apt-get install -y vim

    Never work as root

    root@fb12900d0e7d:/# su - node

    Clone this repo

    node@fb12900d0e7d:~$ git clone https://gitlab.com/henrybravo/someone-yells.git
Cloning into 'someone-yells'...
    node@fb12900d0e7d:~$ cd someone-yells

    build the app

    as this repo has an allready installed app, we only pull updates

    node@fb12900d0e7d:~/someone-yells$ npm update

    check if there are findings in the module tree

    node@fb12900d0e7d:~/someone-yells$ npm audit

    if any, see if you can safely fix the findings in the module tree

    node@fb12900d0e7d:~/someone-yells$ npm audit fix

    run and test app

    run the build (in the node container)

    node@fb12900d0e7d:~/someone-yells$ DEBUG=* npm start &

    Test in a browser

    node@fb12900d0e7d:~/someone-yells$ curl localhost:3000

    as we exposed the app port to localhost you can access the app from the local host's webbrowser too -> http://localhost:3000

    deploy to Amazon EKS or Amazon ECS
