一、概述
这一章就把所有的项目工程都进行容器化，方便后续进行k8s的编排。
对于docker的使用和安装，可以查看我的另一篇文章# Docker的使用&制作Golang微服务镜像并运行
二、Docker搭建所需要的基础设施mysql、redis、kafka、nginx容器
注：一般来说考虑到大存储、安全性、高性能等等问题，不建议数据库进行容器化，我这里纯粹为了方便
1.Docker部署mysql参考
2.Docker部署redis参考
3.Docker部署nginx参考

复制代码<--创建容器命令-->

复制代码4.Docker部署kafka参考
<--创建kafka虚拟网络-->
[root@hecs-235091 kafka]# docker network create --driver bridge --subnet 172.18.0.0/24 --gateway 172.18.0.1 zookeeper_kafka
复制代码<--基于虚拟网络搭建kafka集群，使用docker compose-->
[root@hecs-235091 kafka]# cat docker-compose.yaml

三、项目进行容器化
<--grpc微服务使用goctl 自动生成Dockerfile文件-->
book-store@ubuntu:~/BookStore-Golang/Grpc/User$ goctl docker -go user.go
book-store@ubuntu:~/BookStore-Golang/Grpc/Book$ goctl docker -go book.go
book-store@ubuntu:~/BookStore-Golang/Grpc/Action$ goctl docker -go action.go
book-store@ubuntu:~/BookStore-Golang/Grpc/Order$ goctl docker -go order.go
复制代码<--例如： User-->
FROM golang:alpine AS builder
LABEL stage=gobuilder
ENV CGO_ENABLED 0
ENV GOOS linux
ENV GOPROXY https://goproxy.cn,direct
WORKDIR /build/zero
ADD go.mod .
ADD go.sum .
RUN go mod download
COPY . .
COPY ./etc /app/etc
RUN go build -ldflags="-s -w" -o /app/user ./user.go
FROM alpine
# 自己加入如下两句命令，不然可能不能成功
RUN sed -i 's/https/http/' /etc/apk/repositories
RUN apk add curl
RUN apk update --no-cache && apk add --no-cache ca-certificates tzdata
ENV TZ Asia/Shanghai
WORKDIR /app
COPY --from=builder /app/user /app/user
COPY --from=builder /app/etc /app/etc
CMD ["./user", "-f", "etc/user.yaml"]
复制代码<--webApi的Dockerfile也是进行仿写-->
FROM golang:alpine AS builder
LABEL stage=gobuilder
ENV CGO_ENABLED 0
ENV GOOS linux
ENV GOPROXY https://goproxy.cn,direct
WORKDIR /build/zero
ADD go.mod .
ADD go.sum .
RUN go mod download
COPY . .
COPY ./Etc /app/Etc
RUN go build -ldflags="-s -w" -o /app/bookstore ./bookstore.go
FROM alpine
RUN sed -i 's/https/http/' /etc/apk/repositories
RUN apk add curl
RUN apk update --no-cache && apk add --no-cache ca-certificates tzdata
ENV TZ Asia/Shanghai
WORKDIR /app
COPY --from=builder /app/bookstore /app/bookstore
COPY --from=builder /app/Etc /app/Etc
CMD ["./bookstore"]
复制代码<--进行容器创建命令，用Book举例-->
root@ubuntu:/home/book-store/BookStore-Golang/Grpc/Book# docker build -t caoxunaaa/bs-book-rpc -f Dockerfile .
复制代码<--上传到Docker Hub方便下载-->
root@ubuntu:/home/book-store/BookStore-Golang/Grpc/Book# docker push caoxunaaa/bs-book-rpc
复制代码<--在服务器上pull镜像，并运行容器，使用-v进行配置文件的修改-->
[root@hecs-235091 kafka]# docker pull caoxunaaa/bs-book-rpc
[root@hecs-235091 kafka]# docker run -p 8081:8080 --name book-rpc -v /home/MyProject/etc_conf/etc:/app/etc -d caoxunaaa/bs-book-rpc
复制代码<--配置文件如下，其他同理-->
[root@hecs-235091 MyProject]# cd etc_conf/
[root@hecs-235091 etc_conf]# ls
etc Etc
[root@hecs-235091 etc_conf]# cd etc/
[root@hecs-235091 etc]# ls
action.yaml book.yaml order.yaml user.yaml
[root@hecs-235091 etc]# cat book.yaml
Name: book.rpc
ListenOn: 0.0.0.0:8080
Mysql:
DataSource: bookstore:bookstore@tcp(114.115.169.233:3306)/bs-books?charset=utf8&parseTime=true
CacheRedis:
- Host: 114.115.169.233:6379
Type: node
