1.1 docker基础返回顶部
参考博客：https://blog.51cto.com/lizhenliang
1、什么是docker
1. Docker是使用最广泛的开源容器引擎
2. 一种操作系统基本的虚拟化技术
3. 一种简单的应用程序打包工具
4. 依赖Linux内核特性：Namespace(资源隔离) 和 Cgroup（资源限制）
注：每个容器拥有一套和宿主机完全隔离的文件系统（共用linux内核），程序在这个虚拟容器里运行，就好像在真实的物理机上运行一样。
容器：
1）容器是一个操作系统级别下的虚拟化技术，运行一个容器就行运行一个进程一样
2）容器依赖linux内核特性：Namespace（资源隔离）和Cgroups（资源限制）
资源隔离：
1）Linux Namespaces机制提供一种资源隔离方案，每个namespace看上去就像一个单独的Linux系统。
2）PID,IPC(进程通信),Network等系统资源不再是全局性的，而是属于某个特定的Namespace。
3）每个namespace下的资源对于其他namespace下的资源都是透明，不可见的。
4）系统中可以同时存在两个进程号为0,1,2的进程，由于属于不同的namespace，所以它们之间并不冲突。
5）而在用户层面上只能看到属于用户自己namespace下的资源，例如使用ps命令只能列出自己namespace下的进程。
6）这样每个namespace看上去就像一个单独的Linux系统。
资源限制：
1）为了让容器中的进程更加可控，Docker 使用 Linux cgroups 来限制容器中的进程允许使用的系统资源。
2）可以在启动容器是指定每个容器可以使用的 网络、磁盘、CPU以及内存 等
2、docker思想
1. Docker的思想源于集装箱，集装箱解决了什么问题呢？
2. 在早期运输货物需要不同分类的船，例如运输水果的船，运输生活用品的船
3. 有了集装箱后，在大船上，可以把货物分类到不同的集装箱中，水果一个集装箱，生活用品一个集装箱
4. 它们之间互不影响，只要把货物封装好集装箱里，就可以把不同类的货物一起运走。
5. 通过Docker logo也可以看出所以然来，Docker就像大船，集装箱就是容器。
6. 一条鲸鱼拖着若干个集装箱的经典形象已经深入人心。
3、docker 与 虚拟机比较
1. docker设计小巧，部署迁移快速，运行高效，按照应用隔离，管理人员可以看到所有容器的内容。
2. 虚拟化技术比较臃肿，需要先创建新的系统，按照系统隔离，管理员无法看到系统内部信息。
举例：
1）Docker就是手机中的各种APP，只需要一个系统就可以下载自己所需的应用
2）虚拟化技术相当于苹果手机安装一个庞大软件，这个软件上安装安卓系统、魅族系统等，每个系统上还要安装各类应用。
4、docker解决的问题
1. 高效的利用资源
2. 单台机器得部署多个应用；
3. 应用之间互相隔离（微服务）；
4. 应用之间不能发生资源抢占，每个应用只能使用事先注册申请的资源。
5、Docker架构
1. Docker客户端(Client): docker 命令行工具，用户也可以通过 REST API 与服务器通信
2. Docker服务器(Docker daemon): 服务器组件，以 Linux 后台服务的方式运行， Docker daemon 运行在 Docker host 上，负责创建、运行、监控容器，构建、存储镜像
3. Docker镜像(Image): 可将 Docker 镜像看着只读模板，通过它可以创建 Docker 容器
4. 镜像仓库(Registry): Registry 是存放 Docker 镜像的仓库，Registry 分私有和公有两种
5. Docker容器(Container): Docker 容器就是 Docker 镜像的运行实例
1.2 docker技术应用场景返回顶部
1、场景一：节省项目环境部署时间
1）单项目打包
1. 每次部署项目到测试、生产等环境，都要部署一大堆依赖的软件、工具，时间久，出错概率大。
2. Docker主要理念就是环境打包部署，可在任意Docker Engine运行。
3. 我们只需要将每个项目环境打包到镜像，push到镜像仓库，当有需要部署这个项目时，
直接pull镜像启动容器，这个项目就可以访问了！一次构建多次部署，一劳永逸。
2）整套项目打包
1. 比如有一个产品可以整套部署到客户那里，以往都是派一名实施工程师到客户那部署。
2. 如果用了Docker，我们可以前期将这套项目封装打包起来，实现一键部署，分分钟钟搞定，就不需要再派人过去了。比如官方的Docker Compose编排工具。
3）新开源技术试用
1. 有时，我们想调研一些开源项目，我们可以直接从公共镜像仓库pull项目官方做好镜像启动容器即可。
2、场景二：环境一致性
1. 项目在开发电脑本地运行没问题，到了测试或生产环境就运行不起来。
2. Docker将项目环境打包成镜像，可以在任何Docker Engine部署。
3、场景三：持续集成
1. 一个项目版本快速迭代的测试场景，需要一个合理的CI（持续集成）/CD（持续部署）环境支撑。
2. CI/CD是一个周期性自动化项目测试流程，包括构建、部署、测试、发布等工作，很少需要人工干预。
3. Docker通过项目镜像构建和快速部署，打通测试环境与生产环境，高度保持多个环境之间一致性。
4、场景四：微服务
1. 微服务指尽可能细粒度拆分业务程序架构，由多个独立服务组成业务系统。
2. Docker容器作为这些独立服务的部署单元，每个服务单独部署到一个docker容器中。
1.3 docker安装返回顶部
1、docker安装参考官方文档
1. docker官方文档：https://docs.docker.com/
2. centos安装docker：https://docs.docker.com/install/linux/docker-ce/centos/
注：docker CE只支持 centos7 不支持centos6
2、docker安装
# 1）安装依赖包
yum install -y yum-utils device-mapper-persistent-data lvm2
# 2）添加Docker软件包源(否则doker安装的不是新版本)
yum-config-manager \
--add-repo \
https://download.docker.com/linux/centos/docker-ce.repo
# 3）安装Docker CE
yum install -y docker-ce
# 4）启动Docker服务并设置开机启动
systemctl start docker
systemctl enable docker
# 5）测试docker是否安装成功（hello-world是官方提供的一个测试镜像）
docker run hello-world
# 6）查看docker基本信息
docker info
docker version
3、docker简单使用（创建一个ngixn容器）
# 1、创建一个nginx容器
docker run -it nginx # 2、查看docker运行的容器(可以获取到这个容器的id)
docker ps # 3、访问这个容器
# 进入这个nginx容器（进入的文件系统和宿主机是完全隔离的，有自己独立的文件系统）
docker exec -it 73877e65c07d bash # 4、查看当前容器的 IP
docker inspect 73877e65c07d # 73877e65c07d是通过docekr ps查看到的容器ID
curl 172.17.0.2 # 测试这个nginx容器是否可以访问
举例：创建一个nginx容器
4、docker默认是国外源可以设置成国内镜像源
root@linux-node1 django-docker]# vim /etc/docker/deamon.json # 设置docker镜像源
{
"registry-mirrors": ["http://hub-mirror.c.163.com"]
}
[root@linux-node2 ~]# systemctl restart docker # 重启docker生效
设置docker镜像源
1.4 镜像管理返回顶部
参考博客： https://www.cnblogs.com/sparkdev/p/9092082.html
1、什么是docker镜像
1. docker镜像不包含Linux内核而又精简的Linux操作系统
2. docker镜像是一个分层存储的文件，一个镜像可以创建N个容器
3. 可以这么理解，docker 镜像是 docker 容器的静态视角，docker 容器是 docker 镜像的运行状态。
4. 容器只是对docker镜像的引用，如果docker镜像删除，此镜像创建的容器也都失效
2、docker镜像与容器的区别
1. 当由 ubuntu:14.04 镜像启动容器时，ubuntu:14.04 镜像的镜像层内容将作为容器的 rootfs；
2. 而 ubuntu:14.04 镜像的 json 文件，会由 docker daemon 解析，并提取出其中的容器执行入口 CMD 信息，
以及容器进程的环境变量 ENV 信息，最终初始化容器进程。
3. 当然，容器进程的执行入口来源于镜像提供的 rootfs。
3、rootfs
1. rootfs 是 docker 容器在启动时内部进程可见的文件系统，即 docker 容器的根目录。
2. rootfs 通常包含一个操作系统运行所需的文件系统，例如可能包含典型的类 Unix 操作系统中的目录系统，
如 /dev、/proc、/bin、/etc、/lib、/usr、/tmp 及运行 docker 容器所需的配置文件、工具等。
3. 在传统的 Linux 操作系统内核启动时，首先挂载一个只读的 rootfs，当系统检测其完整性之后，再将其切换为读写模式。
4. 而在 docker 架构中，当 docker daemon 为 docker 容器挂载 rootfs 时，沿用了 Linux 内核启动时的做法，即将 rootfs 设为只读模式。
5. 在挂载完毕之后，利用联合挂载(union mount)技术在已有的只读 rootfs 上再挂载一个读写层。
6. 这样，可读写的层处于 docker 容器文件系统的最顶层，其下可能联合挂载了多个只读的层，
7. 只有在 docker 容器运行过程中文件系统发生变化时，才会把变化的文件内容写到可读写层，并隐藏只读层中的旧版本文件。
4、容器读写层
1. 容器其实是在镜像的最上面加了一层读写层，在运行容器里文件改动时，会先从镜像里要写的文件复制到容器自己的文件系统中（读写层）。
2. 如果容器删除了，最上面的读写层也就删除了，改动也就丢失了。
3. 所以无论多少个容器共享一个镜像，所做的写操作都是从镜像的文件系统中复制过来操作的，并不会修改镜像的源文件
4. 若想持久化这些改动，可以通过docker commit 将容器保存成一个新镜像

5、docker镜像从哪里来
1. Docker Hub是由Docker公司负责维护的公共注册中心，包含大量的容器镜像，Docker工具默认从这个公共镜像库下载镜像。
2. 地址：https://hub.docker.com/explore # docker官方镜像和使用方法参考地址
3. 配置镜像加速器：https://www.daocloud.io/mirror
[root@linux-node2 ~]# curl -sSL https://get.daocloud.io/daotools/set_mirror.sh | sh -s http://f1361db2.m.daocloud.io
[root@linux-node2 ~]# cat /etc/docker/daemon.json # 执行上面命令后就会将镜像源修改成国内的地址
{"registry-mirrors": ["http://f1361db2.m.daocloud.io"]}
[root@linux-node2 ~]# systemctl restart docker # 重启docker生效
1.5 docker常用命令返回顶部

3、容器资源限制
1. 内存限额： 允许容器最多使用500M内存和100M的Swap，并禁用 OOM Killer
docker run -d --name nginx03 --memory="500m" --memory-swap="600m" --oom-kill-disable nginx
2. CPU限额：

1.6 docker将数据挂载到容器的三种方式 返回顶部
1、Docker提供三种方式将数据从宿主机挂载到容器中
1）volumes：Docker管理宿主机文件系统的一部分（/var/lib/docker/volumes） 保存数据的最佳方式。
2）bind mounts：将宿主机上的任意位置的文件或者目录挂载到容器中， 就像软连接一样。
3）tmpfs：挂载存储在主机系统的内存中，而不会写入主机的文件系统（不常用）。
区别：
volume ： 是docker的宿主机文件系统一部分，只有docker可以进行更改，其他进程不能修改
bind mounts ： 是挂载在宿主机文件系统的任意位置，除了docker所有进程都可以进行修改、
2、管理卷
docker volume create nginx-vol # 创建一个数据卷 nginx-vol
docker volume ls # 查看宿主机数据卷信息
docker volume inspect nginx-vol # 查看 nginx-vol 这个数据卷详细信息
ls /var/lib/docker/volumes/nginx-vol/_data # 详细信息中会显示 nginx-vol 这个卷实际在宿主机位置
docker rm -f $(docker ps -a |awk '{print $1}') # 删除所有容器
3、volumes：将容器中的数据持久化到宿主机中
1）用卷创建一个容器：
docker run -d --name=nginx-test -p 88:80 --mount src=nginx-vol,dst=/usr/share/nginx/html nginx
run -d # 后台启动一个nginx容器
--name=nginx-test # 自定义容器名字(默认会是一段随机字符串)
-p 88:80 # 将宿主机的88端口映射到容器的80端口
--mount
src=nginx-vol, # 挂载数据卷名称nginx-vol
dst=/usr/share/nginx/html # 将/usr/share/nginx/html文件挂载到nginx-vol数据卷中
nginx # 使用这个nginx镜像启动容器
vim /var/lib/docker/volumes/nginx-vol/_data/index.html # 修改nginx的 index.html文件可以发现页面发生改变
http://192.168.56.12:88/
2）清理卷：
docker stop nginx-test # 关闭正在使用卷nginx-vol的容器nginx-test
docker rm nginx-test # 删除容器 nginx-test
docker volume rm nginx-vol # 删除卷 nginx-vol
4、bind mounts：将宿主机中的数据挂载到容器中
1）用卷创建一个容器：
docker run -d --name=nginx-test -p 88:80 --mount type=bind,src=/mnt/,dst=/usr/share/nginx/html nginx
run -d # 后台启动一个nginx容器
--name=nginx-test # 自定义容器名字(默认会是一段随机字符串)
-p 88:80 # 将宿主机的88端口映射到容器的80端口
--mount type=bind # 将/usr/share/nginx/html文件夹挂载到宿主机/mnt/文件夹中
src=/mnt/, # 宿主机中挂载目录 /mnt/
dst=/usr/share/nginx/html # 容器中/usr/share/nginx/html文件夹
nginx # 使用这个nginx镜像启动容器
docker exec -it nginx-test bash # 进入容器
cd /usr/share/nginx/html # 进入容器的挂载目录
echo "hello I come here" > index.html # 在目录中创建一个 index.html文件
http://192.168.56.12:88/ # 可以在页面访问到 index.html首页
vim /mnt/index.html # 修改 /mnt/index.html 就等同修改容器中的index.html页面
2）清理：
docker stop nginx-test # 关闭正在使用卷nginx-vol的容器nginx-test
docker rm nginx-test # 删除容器 nginx-test
注意：
1. 如果源文件/目录没有存在，不会自动创建，会抛出一个错误。
2. 如果挂载目标在容器中非空目录，则该目录现有内容将被隐藏。
5、Volume特点：
1. 多个运行容器之间共享数据。
2. 当容器停止或被移除时，该卷依然存在。
3. 多个容器可以同时挂载相同的卷。
4. 当明确删除卷时，卷才会被删除。
5. 将容器的数据存储在远程主机或其他存储上
6. 将数据从一台Docker主机迁移到另一台时，先停止容器，然后备份卷的目录（/var/lib/docker/volumes/）
6、Bind Mounts特点：
1. 从主机共享配置文件到容器。默认情况下，挂载主机/etc/resolv.conf到每个容器，提供DNS解析。
2. 在Docker主机上的开发环境和容器之间共享源代码。例如，可以将Maven target目录挂载到容器中，每次在Docker主机
上构建Maven项目时，容器都可以访问构建的项目包。
3. 当Docker主机的文件或目录结构保证与容器所需的绑定挂载一致时
1.7 容器网络
1、网络模式
• bridge（常用）
–net=bridge
默认网络，Docker启动后创建一个docker0网桥，默认创建的容器也是添加到这个网桥中。
• host（常用）
–net=host
容器不会获得一个独立的network namespace，而是与宿主机共用一个。这就意味着容器不会有自己的网卡信息，而是使用宿主
机的。容器除了网络，其他都是隔离的。
• none（不常用）
–net=none
获取独立的network namespace，但不为容器进行任何网络配置，需要我们手动配置。
• container（不常用）
–net=container:Name/ID
与指定的容器使用同一个network namespace，具有同样的网络配置信息，两个容器除了网络，其他都还是隔离的。
• 自定义网络（最佳方式）
与默认的bridge原理一样，但自定义网络具备内部DNS发现，可以通过容器名或者主机名容器之间网络通信。
'''开启Linux系统的IP转发功能 '''
# 1. 出于安全考虑，Linux系统默认是禁止数据包转发的。
# 2. 所谓转发即当主机拥有多于一块的网卡时，将收到的数据包转发给其他网卡
[root@linux-node4 ~]# vim /etc/sysctl.conf
net.ipv4.ip_forward=1
[root@linux-node4 ~]# systemctl restart network
[root@linux-node4 ~]# sysctl net.ipv4.ip_forward # 输出为1时则证明是成功的
##### 1、下载busybox镜像用于测试
docker pull busybox # 下载一个测试镜像，一些工具都有了
docker run -it busybox # 进入busybox 默认 bash
docker run -it --net=host busybox # 以 host 网络模式进入bash ##### 2、自定义网络模式
docker network create bs-test # 创建一个网络 bs-test
docker run -it --name bs3 --net bs-test busybox # 创建容器bst加入网络bs-test
docker run -it --name bs4 --net bs-test busybox # 创建容器bst加入网络bs-test
ping bs3 # 在bs3和bs4容器中可以通过主机名ping通
ping bs4
docker start bs3 # 启动容器bs3
docker exec -it bs3 sh # 进入bs3 bash环境 ####3、container网络模式
docker run -itd --name bs -p 99:80 busybox # 创建一个名字为bs的容器,并将宿主机99端口映射到80端口
docker run -d --name nginx01 --net container:bs nginx # 使用nginx镜像创建一个容器名nginx01，加入到bs容器中
http://192.168.56.12:99/
docker exec -it bs sh
# 注：bs容器中虽然没有nginx服务，但是可以访问nginx服务，因为nginx01容器加入了
测试 自定义网络 和 container
1.8 Dockerfile: 构建nginx项目镜像返回顶部
'''1.DOckerfile常用命令 '''
FROM python:3.6 # 指定拉取镜像版本
ENV PYTHONUNBUFFERED 1 # 不缓冲stdin、stdout和stderr，直接把输出重定向到文件
MAINITAINER zhangsan # 指定作者
RUN mkdri /code # 运行的linux命令
WORKDIR /code # 指定项目工作根路径
ADD . /code/ # 将宿主机文件复制到镜像中
COPY dj.conf /etc/nginx/conf.d # docker内部文件拷贝
VOLUME ["/data1","/data2"] # 将宿主机文件夹挂载到容器中
EXPOSE 8080 # 暴露端口
CMD ["sh","/code/start.sh"] # 容器启动时要运行的命令
CMD ["python", "manage.py", "runserver", "0:8000"] '''2.生成镜像并运行容器'''
docker build -t nginx:v1 -f Dockerfile-nginx . # 使用Dockerfile-nginx文件生成镜像 nginx:v1
docker push linux-node4.example.com/test/nginx:v1 # 推送镜像到harbor中
docker run -d -p 192.168.56.14:8000:8080 nginx:v1 # 运行docker容器
'''COPY与ADD指令比较 '''
#1.COPY指令：
能够将构建命令所在的主机本地的文件或目录，复制到镜像文件系统 #2.ADD指令：
不仅能够将构建命令所在的主机本地的文件或目录，复制到镜像文件系统
而且可以是一个 URL，这种情况下，Docker 引擎会试图去下载这个链接的文件放到 <目标路径> 去
所以，可以认为ADD是增强版的COPY，支持将远程URL的资源加入到镜像的文件系统
例：ADD http://example.com/big.tar.xz /usr/src/things/
COPY与ADD指令比较
1、使用 Dockerfile-nginx 文件构建一个基础镜像 nginx:v1

[PHP] ;;;;;;;;;;;;;;;;;;;
; About php.ini ;
;;;;;;;;;;;;;;;;;;;
; PHP's initialization file, generally called php.ini, is responsible for
; configuring many of the aspects of PHP's behavior. ; PHP attempts to find and load this configuration from a number of locations.
; The following is a summary of its search order:
; 1. SAPI module specific location.
; 2. The PHPRC environment variable. (As of PHP 5.2.0)
; 3. A number of predefined registry keys on Windows (As of PHP 5.2.0)
; 4. Current working directory (except CLI)
; 5. The web server's directory (for SAPI modules), or directory of PHP
; (otherwise in Windows)
; 6. The directory from the --with-config-file-path compile time option, or the
; Windows directory (C:\windows or C:\winnt)
; See the PHP docs for more specific information.
; http://php.net/configuration.file ; The syntax of the file is extremely simple. Whitespace and lines
; beginning with a semicolon are silently ignored (as you probably guessed).
; Section headers (e.g. [Foo]) are also silently ignored, even though
; they might mean something in the future. ; Directives following the section heading [PATH=/www/mysite] only
; apply to PHP files in the /www/mysite directory. Directives
; following the section heading [HOST=www.example.com] only apply to
; PHP files served from www.example.com. Directives set in these
; special sections cannot be overridden by user-defined INI files or
; at runtime. Currently, [PATH=] and [HOST=] sections only work under
; CGI/FastCGI.
; http://php.net/ini.sections ; Directives are specified using the following syntax:
; directive = value
; Directive names are *case sensitive* - foo=bar is different from FOO=bar.
; Directives are variables used to configure PHP or PHP extensions.
; There is no name validation. If PHP can't find an expected
; directive because it is not set or is mistyped, a default value will be used. ; The value can be a string, a number, a PHP constant (e.g. E_ALL or M_PI), one
; of the INI constants (On, Off, True, False, Yes, No and None) or an expression
; (e.g. E_ALL & ~E_NOTICE), a quoted string ("bar"), or a reference to a
; previously set variable or directive (e.g. ${foo}) ; Expressions in the INI file are limited to bitwise operators and parentheses:
; | bitwise OR
; ^ bitwise XOR
; & bitwise AND
; ~ bitwise NOT
; ! boolean NOT ; Boolean flags can be turned on using the values 1, On, True or Yes.
; They can be turned off using the values 0, Off, False or No. ; An empty string can be denoted by simply not writing anything after the equal
; sign, or by using the None keyword: ; foo = ; sets foo to an empty string
; foo = None ; sets foo to an empty string
; foo = "None" ; sets foo to the string 'None' ; If you use constants in your value, and these constants belong to a
; dynamically loaded extension (either a PHP extension or a Zend extension),
; you may only use these constants *after* the line that loads the extension. ;;;;;;;;;;;;;;;;;;;
; About this file ;
;;;;;;;;;;;;;;;;;;;
; PHP comes packaged with two INI files. One that is recommended to be used
; in production environments and one that is recommended to be used in
; development environments. ; php.ini-production contains settings which hold security, performance and
; best practices at its core. But please be aware, these settings may break
; compatibility with older or less security conscience applications. We
; recommending using the production ini in production and testing environments. ; php.ini-development is very similar to its production variant, except it is
; much more verbose when it comes to errors. We recommend using the
; development version only in development environments, as errors shown to
; application users can inadvertently leak otherwise secure information. ; This is php.ini-production INI file. ;;;;;;;;;;;;;;;;;;;
; Quick Reference ;
;;;;;;;;;;;;;;;;;;;
; The following are all the settings which are different in either the production
; or development versions of the INIs with respect to PHP's default behavior.
; Please see the actual settings later in the document for more details as to why
; we recommend these changes in PHP's behavior. ; display_errors

; Turning on this setting and managing its maximum buffer size can yield some
; interesting side-effects depending on your application and web server.
; You may be able to send headers and cookies after you've already sent output
; through print or echo. You also may see performance benefits if your server is
; emitting less packets due to buffered output versus PHP streaming the output
; as it gets it. On production servers, 4096 bytes is a good setting for performance
; reasons.
; Note: Output buffering can also be controlled via Output Buffering Control

; Error handling and logging ;
;;;;;;;;;;;;;;;;;;;;;;;;;;;;;; ; This directive informs PHP of which errors, warnings and notices you would like
; it to take action for. The recommended way of setting values for this
; directive is through the use of the error level constants and bitwise
; operators. The error level constants are below here for convenience as well as
; some common settings and their meanings.
; By default, PHP is set to take action on all errors, notices and warnings EXCEPT
; those related to E_NOTICE and E_STRICT, which together cover best practices and
; recommended coding standards in PHP. For performance reasons, this is the
; recommend error reporting setting. Your production server shouldn't be wasting
; resources complaining about best practices and coding standards. That's what
; development servers and development settings are for.
; Note: The php.ini-development file has this setting as E_ALL. This
; means it pretty much reports everything which is exactly what you want during
; development and early testing.
;
; Error Level Constants:
; E_ALL - All errors and warnings (includes E_STRICT as of PHP 5.4.0)
; E_ERROR - fatal run-time errors
; E_RECOVERABLE_ERROR - almost fatal run-time errors
; E_WARNING - run-time warnings (non-fatal errors)
; E_PARSE - compile-time parse errors
; E_NOTICE - run-time notices (these are warnings which often result
; from a bug in your code, but it's possible that it was
; intentional (e.g., using an uninitialized variable and
; relying on the fact it is automatically initialized to an
; empty string)
; E_STRICT - run-time notices, enable to have PHP suggest changes
; to your code which will ensure the best interoperability
; and forward compatibility of your code
; E_CORE_ERROR - fatal errors that occur during PHP's initial startup
; E_CORE_WARNING - warnings (non-fatal errors) that occur during PHP's
; initial startup
; E_COMPILE_ERROR - fatal compile-time errors
; E_COMPILE_WARNING - compile-time warnings (non-fatal errors)
; E_USER_ERROR - user-generated error message
; E_USER_WARNING - user-generated warning message
; E_USER_NOTICE - user-generated notice message
; E_DEPRECATED - warn about code that will not work in future versions
; of PHP
; E_USER_DEPRECATED - user-generated deprecation warnings
;
; Common Values:
; E_ALL (Show all errors, warnings and notices including coding standards.)
; E_ALL & ~E_NOTICE (Show all errors, except for notices)
; E_ALL & ~E_NOTICE & ~E_STRICT (Show all errors, except for notices and coding standards warnings.)
; E_COMPILE_ERROR|E_RECOVERABLE_ERROR|E_ERROR|E_CORE_ERROR (Show only errors)
; Default Value: E_ALL & ~E_NOTICE & ~E_STRICT & ~E_DEPRECATED
; Development Value: E_ALL

; http://php.net/error-reporting
error_reporting = E_ALL & ~E_DEPRECATED & ~E_STRICT ; This directive controls whether or not and where PHP will output errors,
; notices and warnings too. Error output is very useful during development, but
; it could be very dangerous in production environments. Depending on the code
; which is triggering the error, sensitive information could potentially leak
; out of your application such as database usernames and passwords or worse.
; For production environments, we recommend logging errors rather than
; sending them to STDOUT.
; Possible Values:
; Off = Do not display any errors
; stderr = Display errors to STDERR (affects only CGI/CLI binaries!)
; On or stdout = Display errors to STDOUT
; Default Value: On
; Development Value: On
; Production Value: Off
; http://php.net/display-errors

; always at least 1 children.
; pm.max_children - the maximum number of children that can
; be alive at the same time.
; pm.start_servers - the number of children created on startup.
; pm.min_spare_servers - the minimum number of children in 'idle'
; state (waiting to process). If the number
; of 'idle' processes is less than this
; number then some children will be created.
; pm.max_spare_servers - the maximum number of children in 'idle'
; state (waiting to process). If the number
; of 'idle' processes is greater than this
; number then some children will be killed.
; ondemand - no children are created at startup. Children will be forked when
; new requests will connect. The following parameter are used:
; pm.max_children - the maximum number of children that
; can be alive at the same time.
; pm.process_idle_timeout - The number of seconds after which
; an idle process will be killed.
; Note: This value is mandatory.
pm = dynamic ; The number of child processes to be created when pm is set to 'static' and the
; maximum number of child processes when pm is set to 'dynamic' or 'ondemand'.
; This value sets the limit on the number of simultaneous requests that will be
; served. Equivalent to the ApacheMaxClients directive with mpm_prefork.
; Equivalent to the PHP_FCGI_CHILDREN environment variable in the original PHP
; CGI. The below defaults are based on a server without much resources. Don't
; forget to tweak pm.* to fit your needs.
; Note: Used when pm is set to 'static', 'dynamic' or 'ondemand'
; Note: This value is mandatory.
pm.max_children = 200 ; The number of child processes created on startup.
; Note: Used only when pm is set to 'dynamic'

; pool - the name of the pool;
; process manager - static, dynamic or ondemand;
; start time - the date and time FPM has started;
; start since - number of seconds since FPM has started;
; accepted conn - the number of request accepted by the pool;
; listen queue - the number of request in the queue of pending
; connections (see backlog in listen(2));
; max listen queue - the maximum number of requests in the queue
; of pending connections since FPM has started;
; listen queue len - the size of the socket queue of pending connections;
; idle processes - the number of idle processes;
; active processes - the number of active processes;
; total processes - the number of idle + active processes;
; max active processes - the maximum number of active processes since FPM
; has started;
; max children reached - number of times, the process limit has been reached,
; when pm tries to start more children (works only for
; pm 'dynamic' and 'ondemand');
; Value are updated in real time.
; Example output:

;
; By default the status page output is formatted as text/plain. Passing either
; 'html', 'xml' or 'json' in the query string will return the corresponding
; output syntax. Example:
; http://www.foo.bar/status
; http://www.foo.bar/status?json
; http://www.foo.bar/status?html
; http://www.foo.bar/status?xml
;
; By default the status page only outputs short status. Passing 'full' in the
; query string will also return status for each pool process.
; Example:
; http://www.foo.bar/status?full
; http://www.foo.bar/status?json&full
; http://www.foo.bar/status?html&full
; http://www.foo.bar/status?xml&full
; The Full status returns for each process:
; pid - the PID of the process;
; state - the state of the process (Idle, Running, ...);
; start time - the date and time the process has started;
; start since - the number of seconds since the process has started;
; requests - the number of requests the process has served;
; request duration - the duration in µs of the requests;
; request method - the request method (GET, POST, ...);
; request URI - the request URI with the query string;
; content length - the content length of the request (only with POST);
; user - the user (PHP_AUTH_USER) (or '-' if not set);
; script - the main script called (or '-' if not set);
; last request cpu - the %cpu the last request consumed
; it's always 0 if the process is not in Idle state
; because CPU calculation is done when the request
; processing has terminated;
; last request memory - the max amount of memory the last request consumed
; it's always 0 if the process is not in Idle state
; because memory calculation is done when the request
; processing has terminated;
; If the process is in Idle state, then informations are related to the
; last request the process has served. Otherwise informations are related to
; the current request being served.
; Example output:

docker build -t php:v1 -f Dockerfile-php . # 使用 Dockerfile-nginx 文件构建一个基础镜像 php:v1
docker images #确认 php:v1镜像是否构建成功
docker run -d --name php01 php:v1 # 使用php:v1镜像启动一个容器 php01
docker ps -l # 确认 容器php01是否可以成功启动
docker exec -it php01 bash # 进入容器php01 bash环境，确定一下php是否安装成功
2、dockerfile的作用
docker可以根据Dockerfile中的指令来构建docker镜像。
Dockerfile是一个文本文件，其应当包含用户想要构建一个镜像的所有指令。
FROM # build是基于哪个镜像来构建新的镜像
ENV PATH $PATH:/usr/local/nginx/sbin # 配置环境变量，注意此配置会在container中生效
COPY src dest # docker内部文件系统中拷贝
ADD src dest # 将宿主机本地文件拷贝到docker中
RUN command # 执行linux命令
CMD ["sh","/code/start.sh"] # 启动服务
EXPOSE 8080 # 暴露端口
WORKDIR /path #在此指令之后的操作，以及container的默认进入路径都将时 /path目录
VOLUME ['/path1', '/path2'] # 基于此镜像创建的container都将拥有VOLUME中指定的挂在目录
3、Dockerfile编写优化
1. 一个docker image只负责一个职责。当有多个服务时，请将服务分别docker化，然后组合使用这些docker images。
2. 就像编程一样，当一个字符串出现多次时，请用ARG来声明变量取代hard code。
3. 拷贝文件到镜像时，ADD负责网络资源的拷贝，COPY负责本地文件的COPY。
4. 尽量使用cache，docker在build镜像时可以利用缓存，缓存的原则时：当重复构建时，如果单个指令的内容没有变化，则docker会默认使用cache。
5. 将相同变化频率的RUN指令合并成一个。注意，一定要是相同变化频率的RUN命令才能合并成一个，不然缓存的特性就无法使用了。
6. 合理使用.dockerignore，减少images的体积。
7. 尽量使用CMD，VOLUME将image进行服务化。
8. 使用LABEL对image进行元信息的描述。
9. 单一服务的基础镜像如何可以请使用alpine版本的镜像来减少image的体积。
