The hello-go-deploy-amazon-ec2 docker image on DockerHub
This repos github webpage built with concourse

OVERVIEW

Every 2 seconds this App will print,

    INFO[0000] Let's Start this!
    Hello everyone, count is: 1
    Hello everyone, count is: 2
    Hello everyone, count is: 3
    etc...

PREREQUISITES

You will need the following go packages,

go get -u -v github.com/sirupsen/logrus
go get -u -v github.com/cweill/gotests/...

SOFTWARE STACK

DEVELOPMENT
- go
OPERATIONS
- concourse/fly (optional)
- docker
SERVICES

- amazon elastic compute cloud (ec2)

RUN

To run.sh,

cd hello-go-deploy-amazon-ec2-code
go run main.go

To create-binary.sh,

cd hello-go-deploy-amazon-ec2-code/bin
go build -o hello-go ../main.go
./hello-go

This binary will not be used during a docker build since it creates it's own.

STEP 1 - TEST

To create unit _test files,

cd hello-go-deploy-amazon-ec2-code
gotests -w -all main.go

To run unit-tests.sh,

go test -cover ./... | tee test/test_coverage.txt
cat test/test_coverage.txt

STEP 2 - BUILD (DOCKER IMAGE VIA DOCKERFILE)

This docker image is built in two stages. In stage 1, rather than copy a binary into a docker image (because that can cause issues), the Dockerfile will build the binary in the docker image. In stage 2, the Dockerfile will copy this binary and place it into a smaller docker image based on alpine, which is around 13MB.

To build.sh with a Dockerfile,

cd hello-go-deploy-amazon-ec2-code/build
docker build -f Dockerfile -t jeffdecola/hello-go-deploy-amazon-ec2 .

You can check and test this docker image,

docker images jeffdecola/hello-go-deploy-amazon-ec2
docker run --name hello-go-deploy-amazon-ec2 -dit jeffdecola/hello-go-deploy-amazon-ec2
docker exec -i -t hello-go-deploy-amazon-ec2 /bin/bash
docker logs hello-go-deploy-amazon-ec2
docker rm -f hello-go-deploy-amazon-ec2

STEP 3 - PUSH (TO DOCKERHUB)

You must be logged in to DockerHub,

docker login

To push.sh,

docker push jeffdecola/hello-go-deploy-amazon-ec2

Check the hello-go-deploy-amazon-ec2 docker image at DockerHub.

STEP 4 - DEPLOY (TO EC2)

Coming soon.

CONTINUOUS INTEGRATION & DEPLOYMENT

Refer to ci-README.md on how I automated the above steps using concourse.
