This command copies all the files, directories and subdirectories from the current directory where the Dockerfile is located and moves them to the WORKDIR defined above

This directory doesnвЂ™t already exist, so, it will be created.ДЄDD. WORKDIR /go/src//gilcrest/go-API-template - This command sets the working directory to the path given. LetвЂ™s break down whatвЂ™s happening in this file:ДЇROM golang:latest - This command tells Docker to pull the golang image with the latest tag from the official Docker repository as the first layer. userServer # Document that the container uses port 8080 EXPOSE 8080 # Document that the container uses port 5432 EXPOSE 5432 # runs command at most recent WORKDIR ENTRYPOINT. # Switch WORKDIR to directory where server main.go lives WORKDIR /go/src//gilcrest/go-API-template/cmd/server # Build the go-API-template userServer command inside the container # at the most recent WORKDIR RUN go build -o userServer # Run the userServer command by default when the container starts. FROM golang:latest # Create WORKDIR (working directory) for app WORKDIR /go/src//gilcrest/go-API-template # Copy the local package files to the container's workspace # (in the above WORKDIR) ADD. # Start from a Debian image with the latest version of Go installed # and a workspace (GOPATH) configured at /go. I do not change any of the default settings, which means Postgres listens on port 5432.ДЇor database configuration (dbname, host, port, user, password), IвЂ™m storing everything as environment variables and accessing them within my Go program via os.Getenv, e.g.:

I read a lot of different blogs and how-tos on Docker and wasnвЂ™t able to really put it all together until I read this book.ДЇor my database, I have PostgreSQL running locally on my Mac using Postgres.app - you can use whatever you like, but I find this product incredibly simple to use. Once installed, youвЂ™ll need to familiarize yourself with the various docker commands and idioms.

Part 1 - Simple build against local PostgreSQL, exposing ports 5432 for PostgreSQL and 8080 for http traffic from my local host to my containerДЇirst off, you must have Docker for Mac installed. Right now, from a networking perspective, my app is pretty simple - it needs connectivity on two ports: 1 port for database traffic, 1 port for http traffic.

This post is about вЂњcontainerizingвЂќ my API using Docker and getting it to work locally on my Mac. Baby steps for me though - I want to get everything working locally first. As part of it, I want to be able to вЂњContainerizeвЂќ my app using docker and deploy it to вЂњthe cloudвЂќ. IвЂ™m working through creating a RESTful API template.
