最近需要一个文档应用，需要支持设置文档过期时间与文档打开次数，即阅后自焚，于是上github找到一个特别匹配的项目。pastme：https://github.com/LucienShui/PasteMe

项目部署教程

docker部署方式

通过查看项目部署方式，查找到该项目可通过docker镜像形式部署，只需要使用该docker配置文件，输入命令，即可一件部署：

js
version: "3"

services:
  pasteme-frontend:
    image: pasteme/frontend:3.4.1
    container_name: pasteme-frontend
    depends_on:
      - pasteme-backend
    healthcheck:
      test: ["CMD", "curl", "-so", "/dev/null", "localhost:8080/usr/config.json"]
      interval: 45s
      timeout: 3s
      retries: 3
    restart: always
    //前端页面端口可配置成其它端口,6001:8080
    ports:
      - 80:8080
    volumes:
      - ./data/nginx-logs/:/var/lib/pasteme/
      - ./data/frontend-usr/:/www/pasteme/usr/

  pasteme-backend:
    image: pasteme/go-backend:3.5.1
    container_name: pasteme-backend
    depends_on:
      - pasteme-mysql
    healthcheck:
      test: ["CMD", "wget", "-O", "/dev/null", "localhost:8000/api/v3/?method=beat"]
      interval: 45s
      timeout: 3s
      retries: 3
    restart: always
    volumes:
      - ./data/backend-config/:/etc/pastemed/
    logging:
      driver: "json-file"
      options:
        max-file: "3"
        max-size: "128m"

  pasteme-mysql:
    image: mysql:5.5
    container_name: pasteme-mysql
    healthcheck:
      test: ["CMD", "mysqladmin" ,"ping", "-h", "localhost"]
      interval: 45s
      timeout: 3s
      retries: 3
    restart: always
    command: [
      '--character-set-server=utf8mb4',
      '--collation-server=utf8mb4_unicode_ci'
    ]
    environment:
      MYSQL_USER: username
      MYSQL_PASSWORD: password
      MYSQL_ROOT_PASSWORD: password
      MYSQL_DATABASE: pasteme
      MYSQL_MAX_ALLOWED_PACKET: 128M
      MYSQL_INNODB_LOG_FILE_SIZE: 64M
    volumes:
      - ./data/mysql:/var/lib/mysql
    logging:
      driver: "json-file"
      options:
        max-file: "3"
        max-size: "128m"

配置提示

其中前端项目可更换其它对外端口，即将ports: - 80:8080 修改为 ports: - 6001:8080。这样对外端口就为6001

在当前目录下执行命令即可下载安装镜像文件。

shell
docker-compose up -d

在安装过程中由于docker镜像网站被国内封禁。可添加国内镜像。添加源后再安装镜像即可。

shell
sudo tee /etc/docker/daemon.json <<-'EOF'
{
    "registry-mirrors": [
     "https://docker.m.daocloud.io",
     "https://docker.imgdb.de",
     "https://docker-0.unsee.tech",
     "https://docker.hlmirror.com",
     "https://docker.1ms.run",
     "https://func.ink",
     "https://lispy.org",
     "https://docker.xiaogenban1993.com"
    ]
}
EOF
#重启docker服务
sudo systemctl daemon-reload && sudo systemctl restart docker
#验证源是否加载成功
sudo docker pull hello-world

项目部署后，发现文档有限制，只可创建最多查看3次的文档，需要修改后端代码，于是需要将docker内的开源后端项目改为本地编译的镜像。

修改后端项目docker-compose配置

将后端代码库通过git拉取到服务器内，后端开源项目地址https://github.com/PasteUs/PasteMeGoBackend 再将Dockerfile文件内的配置修改，添加go模块载入代理

config
go env -w GOPROXY=https://goproxy.cn

修改后配置文件

js
FROM pasteme/golang:1.16-alpine AS builder
COPY ./ /go/src/github.com/PasteUs/PasteMeGoBackend
WORKDIR /go/src/github.com/PasteUs/PasteMeGoBackend
go env -w GOPROXY=https://goproxy.cn
RUN go mod download
RUN go build main.go
RUN mkdir /pastemed && \
    cp config.example.json docker-entrypoint.sh /pastemed/ && \
    cp main /pastemed/pastemed

FROM alpine:3
LABEL maintainer="Lucien Shui" \
      email="lucien@lucien.ink"
ENV TZ=Asia/Shanghai
COPY --from=builder /pastemed /usr/local/pastemed
RUN chmod +x /usr/local/pastemed/pastemed && \
    mkdir /data && \
    mkdir -p /etc/pastemed/ && \
    apk --no-cache add build-base tzdata && \
    cp /usr/share/zoneinfo/Asia/Shanghai /etc/localtime && \
    echo "Asia/Shanghai" > /etc/timezone
CMD ["/usr/bin/env", "sh", "/usr/local/pastemed/docker-entrypoint.sh"]
EXPOSE 8000

再修改原始的docker-compose文件配置将加载的镜像修改为本地编译

config
修改前
image: pasteme/go-backend:3.5.1
修改后
build: ./pasteme-backend
#该目录为拉取的代码目录

修改后的配置文件

shell
version: "3"

services:
  pasteme-frontend:
    image: pasteme/frontend:3.4.1
    container_name: pasteme-frontend
    depends_on:
      - pasteme-backend
    healthcheck:
      test: ["CMD", "curl", "-so", "/dev/null", "localhost:8080/usr/config.json"]
      interval: 45s
      timeout: 3s
      retries: 3
    restart: always
    //前端页面端口可配置成其它端口,6001:8080
    ports:
      - 80:8080
    volumes:
      - ./data/nginx-logs/:/var/lib/pasteme/
      - ./data/frontend-usr/:/www/pasteme/usr/

  pasteme-backend:
    build: ./pasteme-backend
    container_name: pasteme-backend
    depends_on:
      - pasteme-mysql
    healthcheck:
      test: ["CMD", "wget", "-O", "/dev/null", "localhost:8000/api/v3/?method=beat"]
      interval: 45s
      timeout: 3s
      retries: 3
    restart: always
    volumes:
      - ./data/backend-config/:/etc/pastemed/
    logging:
      driver: "json-file"
      options:
        max-file: "3"
        max-size: "128m"

  pasteme-mysql:
    image: mysql:5.5
    container_name: pasteme-mysql
    healthcheck:
      test: ["CMD", "mysqladmin" ,"ping", "-h", "localhost"]
      interval: 45s
      timeout: 3s
      retries: 3
    restart: always
    command: [
      '--character-set-server=utf8mb4',
      '--collation-server=utf8mb4_unicode_ci'
    ]
    environment:
      MYSQL_USER: username
      MYSQL_PASSWORD: password
      MYSQL_ROOT_PASSWORD: password
      MYSQL_DATABASE: pasteme
      MYSQL_MAX_ALLOWED_PACKET: 128M
      MYSQL_INNODB_LOG_FILE_SIZE: 64M
    volumes:
      - ./data/mysql:/var/lib/mysql
    logging:
      driver: "json-file"
      options:
        max-file: "3"
        max-size: "128m"

重新安装项目

先删除原有的镜像再重新安装

shell
#查找原有镜像
docker images -a
#删除镜像
docker rmi -f  6d46013a1ed 915d0aad7a5 d404d78aa79

根据修改配置文件安装镜像

shell
docker-compose up -d

安装成功后即可看到部署修改后的后端服务
