Containerized Golang and Vuejs applications

Sections:

• Preparations
• Assumptions
• Running the environment
• Setting up HTTPS for the Golang Server
• Gitbook for Docker

Preparations:

• Install Docker
• Clone this repo: git clone https://github.com/jbelmont/docker-workshop.git
• Docker Images:

docker pull mongo:3.4.5
docker pull golang:1.8.3
docker pull redis:3.2.9
docker pull mhart/alpine-node:8.0.0

Assumptions:

• During this workshop the following ports will be used: 8080, 8081, 3000, 3001.

If they are not available on your machine, adjust the Docker CLI commands accordingly.

Prerequisites

Since Docker leverages the Operating System's virtualization technologies, the install requirements for Docker are specific.

OS X requirements:

• 2010 or newer model with Intel's MMU virtualization
• OS X El Capitan 10.11 or newer

Windows requirements:

• 64-bit Windows
• Windows 10 Pro, Enterprise or Education (not Home, not Windows 7 or 8) to install Hyper-V
• Windows 10 Anniversary Update or better
• Access to your machine's BIOS to turn on virtualization

Install Docker

Running the environment

• Run the script npm run build in order to build the 2 images for the frontend and the backend

• Run the script npm run dev in order to actually spin up the containers

  • Under the hood this script runs docker-compose up frontend backend db redis

Setting up HTTPS for the Golang Server

• You will need to add a key and a certificate
• This can easily be done by using the following command:
  • go run $(go env GOROOT)/src/crypto/tls/generate_cert.go --host localhost
  • This will add a key.pem and cert.pem to the current directory
  • If running windows you should be able to the following command:
  • go run %go env GOROOT%/src/crypto/tls/generate_cert.go --host localhost
• Additionally you will have to update the http server in main.go
  • http.ListenAndServeTLS(":3001", "cert.pem", "key.pem", router)
