docker运行一个二进制文件(部署go)

1、项目目录结构

2、构建可执行二进制文件

#构建可执行二进制文件
CGO_ENABLED=0 GOARCH=amd64 go build -o bh-go-server-sms server.go

3、运行文件目录结构
go二进制文件bh-go-server-sms以及配置文件config.env

[root@bogon bh-go-server-sms]# tree
.
├── bh-go-server-sms
├── config
│?? ├── config.conf.go
│?? ├── config.env
│?? ├── config.env.example
│?? ├── readme_ssl.md
│?? ├── server.key
│?? └── server.pem
└── Dockerfile

1 directory, 8 files

4、通过Dockerfile创建镜像文件

[root@bogon bh-go-server-sms]# cat Dockerfile 
FROM busybox
LABEL RoES roes@163.com
WORKDIR /root
ADD ./bh-go-server-sms ./bh-go-server-sms
ADD ./config ./config
EXPOSE 51003
ENTRYPOINT  ["./bh-go-server-sms"]

# 基础镜像是docker仓库的busybox
 FROM busybox
#  作者签名
 MAINTAINER RoES roes@163.com
# WORKDIR 工作目录, 在docker中的目录，可以自己指定
# ADD [源文件] [目标文件]
# EXPOSE 80 端口号是多少
# ENTRYPOINT ["./bh-go-server-sms"] 这个是在运行容器时会执行的命令，运行二进制文件，容器运行go二进制文件跟随运行。

5、打包镜像
给go二进制文件授权执行权限

chmod 755 bh-go-server-sms

docker build -t go-server-sms .

. 表示使用当前上下文中的 Dockerfile 文件,创建镜像名为go-server-sms的镜像.

[root@bogon bh-go-server-sms]# docker build -t go-server-sms .

Step 7/7 : ENTRYPOINT ./bh-go-server-sms
 ---> Using cache
 ---> 52f8514d592a
Successfully built 52f8514d592a

出现Successfully built则创建镜像成功，镜像ID为52f8514d592a

root@bogon bh-go-server-sms]# docker images
REPOSITORY                                      TAG                 IMAGE ID            CREATED             SIZE
go-server-sms                                   latest              52f8514d592a        37 minutes ago      20 MB

6、启动镜像运行容器

docker run --name go-server-sms -d -p 51003:51003 bh-go-server-sms

7、查看

[root@bogon bh-go-server-sms]# docker ps -a
CONTAINER ID        IMAGE                                     COMMAND                  CREATED             STATUS                   PORTS                              NAMES
1e5d4f62c8dd        bh-go-server-sms                          "./bh-go-server-sms"     37 minutes ago      Up 37 minutes            0.0.0.0:51003->51003/tcp           bh-go-server-sms

[root@bogon bh-go-server-sms]# ps -ef|grep ./bh-go-server-sms 
root      3435  3418  0 15:49 ?        00:00:01 ./bh-go-server-sms
root      3539  1704  0 16:28 pts/0    00:00:00 grep --color=auto ./bh-go-server-sms

8、使用docker-compose部署
创建docker-compose.yml文件

[root@bogon bh-go-server-sms]# cat docker-compose.yml 
version: "3"
services:
  go-web:
    image: bh-go-server-sms
    ports:
      - "51003:51003"

运行docker-compose

• docker-compose up -d 后台运行

[root@bogon bh-go-server-sms]# docker-compose up
