ebs-docker-hello's Introduction

rcadena/ebs-docker-hello

Super simple golang webapp docker image project for running on Amazon Elastic Beanstalk.

Runs a web server on :8080 and listens for /.

Prints to stdout using log.

Reads a template file from a templates folder in $GOPATH.

It uses "github.com/gorilla/mux" for routing, though its use is simply to verify that vendor libs are imported during the container build. But you could do without.

It is based on google/golang-runtime

Verify Locally

If you want to see if the docker image runs the app.

Build the image:

docker build --rm --tag=ebs-docker-hello .

Run the image in a new container

docker run -p 8080 -d ebs-docker-hello

Make a request:

$: curl localhost:8080

<!DOCTYPE html>
<html>
<head>
<title>Docker on Beanstalk</title>
</head>
<body>
    <center>
        Hello Docker on Beanstalk!
    </center>
</body>

Run on AWS

This is quite involved, so I made a video run-through available on YouTube

Notes

Currently the Dockerfile specifies the full $GOPATH as /gopath/src/app. Docker v1.3 will expand environment variables in WORKDIR so that the file can then just say:

WORKDIR $GOPATH
