Docker部署go语言web服务器

一.准备

1.win10环境

2.下载建议迅雷

二.安装docker

1.右击开始->应用与功能->启用Hyper-V和容器功能

2.安装docker

官方地址：下载docker

安装后打开docker，在命令行输入 docker version查看client和server信息

 3.安装mingw使用make

下载地址： mingw    并加上环境变量

三.docker 部署

1.交叉编译

创建makefile文件，代码如下：主要使用 build-linux

# Go parameters
GOCMD=go
GOBUILD=$(GOCMD) build
GOCLEAN=$(GOCMD) clean
GOTEST=$(GOCMD) test
GOGET=$(GOCMD) get
PROJECT_DIR=..
BINARY_DIR=dist
BINARY_NAME=$(BINARY_DIR)/ams_backend
BINARY_LINUX=$(BINARY_NAME)_linux

all: test build
build: 
	$(GOBUILD) -o $(BINARY_NAME) -v $(PROJECT_DIR) && cp -rf $(PROJECT_DIR)/config $(PROJECT_DIR)/docs $(BINARY_DIR)
test:
	$(GOTEST) -v $(PROJECT_DIR)/...
test_coverage:
	$(GOTEST) $(PROJECT_DIR)/... -coverprofile=coverage.out
clean: 
	$(GOCLEAN)
	rm -f $(BINARY_NAME)
	rm -f $(BINARY_LINUX)
run:
	$(GOBUILD) -o $(BINARY_NAME) -v $(PROJECT_DIR)/...
	./$(BINARY_NAME)
tidy:
	go mod tidy
vet:
	go vet
lint:
	golangci-lint run --enable-all


# Cross compilation
build-linux:
	CGO_ENABLED=0 GOOS=linux GOARCH=amd64 $(GOBUILD) -o $(BINARY_LINUX) -v $(PROJECT_DIR) && cp -rf $(PROJECT_DIR)/config $(PROJECT_DIR)/docs $(BINARY_DIR)

2.服务器镜像配置文件

创建ams.dockerfile

dist文件夹包含 make build-linux的文件和服务器配置文件

        复制文件夹到镜像工作路径

        设置命令CMD

                初始化服务器，当前服务器需要参数：init -c ${E_CONFIG_FILE}

                启动服务器，当前服务器需要参数 ：server -c ${E_CONFIG_FILE}

FROM alpine:3.15.0

ARG RUN_ENV=test
ARG BIN_DIR=dist
ARG BIN_FILE=ams_backend_linux
ARG CONFIG_FILE=settings.${RUN_ENV}.yml
ARG WORK_DIR=/root


ENV E_WORK_DIR=${WORK_DIR}
ENV E_BIN_FILE=${BIN_FILE}
ENV E_CONFIG_FILE=config/${CONFIG_FILE}

COPY ${BIN_DIR}/ ${WORK_DIR}/

CMD ["sh", "-c", "cd ${E_WORK_DIR} && ./${E_BIN_FILE} init -c ${E_CONFIG_FILE} && ./${E_BIN_FILE} server -c ${E_CONFIG_FILE}"]

3.docker-compose 配置文件

创建docker-compose.yml

容器配置和镜像build配置

基础镜像大概使用了nginx，mariadb， redis，和前面的服务器基础镜像apline

version: "3.9"
services:
  # 网关服务，转发 文件服务请求 和 ams backend
  ams_proxy:
    depends_on:
      - ams_backend
      - nise_fileserv
    image: nginx:1.21.5-alpine
    volumes:
      - ./data/nginx/conf.d:/etc/nginx/conf.d:ro
      - ./data/nginx/logs:/var/log/nginx
    networks:
      - ams-backend
    ports:
      - "8080:80"
    deploy:
      placement:
        constraints:
          - node.role == manager
  # 数据库
  ams_db:
    image: mariadb:10.3.32
    volumes:
#      - ./data/mariadb/conf/conf.d:/etc/mysql/conf.d:ro
#      - ./data/mariadb/conf/mariadb.conf.d:/etc/mysql/mariadb.conf.d:ro
      - ./data/mariadb/data:/var/lib/mysql
      - ./data/mariadb/docker-entrypoint-initdb.d:/docker-entrypoint-initdb.d:ro
    env_file:
      - .env
    environment:
      # TODO: 使用输入加密密码
      - MYSQL_ROOT_PASSWORD=nzai123!@#
      - MYSQL_TZ=Asia/Shanghai
    networks:
      - ams-backend
    expose:
      - "3306"
    ports:
      - "13306:3306"
    restart: always

  # https://hub.docker.com/_/redis?tab=description
  # redis
  ams_redis:
    image: redis:6.2.6-alpine
    volumes:
      - ./data/redis/data:/data
      # TODO: password and other config items should be set
      # - ./data/redis/conf:/usr/local/etc/redis
    # command: redis-server /usr/local/etc/redis/redis.conf --save 300 1 --loglevel warning
    command: redis-server --save 300 1 --loglevel warning
    networks:
      - ams-backend
    ports:
      - "16379:6379"
    restart: always

  # 后台服务
  ams_backend:
    depends_on:
      - ams_db
    image: '${DOCKER_IMAGE_AMS_BACKEND?Variable not set}:${TAG-latest}'
    env_file:
      - .env
    environment:
      - AMS_DB_HOST=ams_db
      - AMS_DB_USER_HOST=ams_db
    networks:
      - ams-backend
    expose:
      - "8003"
    restart: always
    build:
      context: .
      dockerfile: ams.dockerfile
      args:
        RUN_ENV: ${RUN_ENV-test}
# 网络配置
networks:
  ams-backend:
    external: false

4.使用shell开始build

创建build.sh文件：docker-compose创建镜像配置

#! /usr/bin/env sh

# Exit in case of error
set -e

TAG=${TAG?Variable not set} \
DOCKER_IMAGE_AMS_BACKEND=${DOCKER_IMAGE_AMS_BACKEND?Variable not set} \
docker-compose \
-f docker-compose.yml -p ams-backend \
build

创建v1.0_build.sh文件：更新依赖，交叉编译，执行build.sh创建镜像

#! /usr/bin/env sh

# Exit in case of error
set -e

cur_dir=$(pwd)

# update dependencies
cd .. && go mod tidy && go mod vendor

cd "${cur_dir}"
# read Makefile
make build-linux

# execute build.sh with params
TAG=v1.0 DOCKER_IMAGE_AMS_BACKEND=nise/ams/backend ./build.sh

5.开启容器服务组

创建v1.0_start.sh文件：

#! /usr/bin/env sh

# Exit in case of error

TAG=v1.0 DOCKER_IMAGE_AMS_BACKEND=nise/ams/backend docker-compose -f docker-compose.yml -p nise_ams up -d

四.部署结果

1.nginx，redis，mariadb，ams/backend四个镜像

2. 一个容器组，里面这四个容器
