# Simple example of a Docker server application

# Test a Go API server running in a Docker container

# Go API code is adapted from https://github.com/HakaseLabs/source-blog/blob/master/rest-api/main.go

# The image is already build for use. See https://hub.docker.com/repository/docker/dockerfornovices/api-server

# Run with

# `docker container run --publish 8089:8000 --rm --detach --name myAPIserver dockerfornovices/api-server:$VERSION`

# Test with `curl -v http://0.0.0.0:9089/people`

#Get Health check status with `docker container inspect --format '{{.State.Health.Status}}' <ID>"

docker container run --publish 8089:8000 --rm --detach --name myAPIserver dockerfornovices/api-server:$VERSION
