### 前言 ###

前段时间, 有一个部署项目使用`Docker`进行部署. 其实部分命令和参数含义已经有点遗忘. 记在此处防止遗忘.

--------------------

### Docker命令 ###

##### docker run #####

*  `--rm`: 此参数表示.当使用容器结束后销毁.  
    [docker run的–rm选项详解][docker run_rm]
 *  `-v`: 此参数表示将本地磁盘挂载到`docker容器内部`.  
    [docker run -v参数][docker run -v]
 *  Others  
    [Docker命令详解（run篇）][Docker_run]  
    [Docker命令\_各种参数简介（run、v、rm、-w、-u、-e）][Docker_run_v_rm_-w_-u_-e]
 *  Docker 安装 Python3  
    [Docker安装Python3.5][Docker_Python3.5]

--------------------

### 实战命令 ###

*  Tips1

# 创建Docker网络
    docker network create qqbot
    
    # 拉取2个镜像. 默认版本为latest.
    docker pull alpine
    docker pull yobot/yobot

*  Tips2

# 运行python3镜像. 通关其处理一些文本操作. -v表示文件夹共享
    docker run --rm -v ${PWD}:/work -w /work python:3.7-slim-buster python3 -c "
    import json
    import urllib.request
    import ssl
    url = 'https://api.github.com/repos/Mrs4s/go-cqhttp/releases'
    resp = urllib.request.urlopen(url).read().decode('utf-8')
    assets = json.loads(resp)[0]['assets']
    for item in assets:
        if item['name'].endswith('linux-amd64.tar.gz'):
            download = item['browser_download_url']
            break
    resp = urllib.request.urlopen(download).read()
    f = open('go-cqhttp.tar.gz', 'wb')
    f.write(resp)
    f.close()
    "

*  Tips3

# 写入一个Dockerfile文件 
    # 随后通过docker build进行构建镜像
    # 随后删除Dockerfile文件
    echo "
    FROM alpine:latest
    ADD go-cqhttp /bin/go-cqhttp
    WORKDIR /bot
    ENTRYPOINT /bin/go-cqhttp
    ">Dockerfile
    docker build . -t gocqhttp
    rm Dockerfile -f

*  Tips4

# 初始化镜像. 其实为了go-cqhhtp初始化文件
    echo "initializing gocqhttp configure file"
    docker run --rm \
               -v ${PWD}/gocqhttp_data:/bot \
               gocqhttp >/dev/null 2>&1

*  Tips5

# 使用python3镜像更改配置文件
    docker run --rm -v ${PWD}:/work -w /work -e qqid -e qqpassword python:3.7-slim-buster python3 -c "
    import json, os, random, string
    access_token = ''.join(random.choices(string.ascii_uppercase + string.ascii_lowercase + string.digits, k=16))
    with open('yobot_data/yobot_config.json', 'w') as f:
        json.dump({'access_token': access_token}, f, indent=4)
    with open('gocqhttp_data/config.json', 'r+') as f:
        config = json.load(f)
        config['uin'] = int(os.environ['qqid'])
        config['password'] = os.environ['qqpassword']
        config['access_token'] = access_token
        config['enable_db'] = False
        config['web_ui']['enabled'] = False
        config['http_config']['enabled'] = False
        config['ws_config']['enabled'] = False
        config['ws_reverse_servers'] = [{
            'enabled': True,
            'reverse_url': 'ws://yobot:9222/ws/',
            'reverse_api_url': '',
            'reverse_event_url': '',
            'reverse_reconnect_interval': 3000
        }]
        f.seek(0)
        f.truncate()
        json.dump(config, f, indent=4)
    "

*  Tips6

# 启动镜像 开放端口9222 使用网络qqbot 使用共享文件夹 
    echo "starting yosbot"
    docker run -d \
               --name yobot \
               -p 9222:9222 \
               --network qqbot \
               -v ${PWD}/yobot_data:/yobot/yobot_data \
               yobot/yobot

*  Tips7

# 启动qqhttp镜像
    echo "starting gocqhttp"
    docker run -it \
               --name gocqhttp \
               --network qqbot \
               -v ${PWD}/gocqhttp_data:/bot \
               gocqhttp
