使用docker后,在项目代码目录下,写dockerfile文件,非常方便把项目代码直接打包到docker镜像中,如有哪些文件不想被打包进去,可以在.dockerignore文件中定义
dockerfile解析:
生成wordpress镜像
dockerbuild-tcsphere/wordpress:4.2.
查看当前主机本地都有哪些docker镜像
dockerimages
创建wordpress准备
查看主机ip地址
ifconfigeth0192.168.1.20
创建wordpress容器:
dockerrun-d-p80:80--namewordpress-ewordpress_db_host=192.168.1.20-ewordpress_db_user=admin-ewordpress_db_password=csphere2015csphere/wordpress:4.249d0cddb4e6998a43285fe09165030ba80485065867b9cb8fae9fbdb97cd077f
参数解析:
访问http://your_ip,选择语言,并进行设置wordpress
entrypoint解析
定义:
anentrypointallowsyoutoconfigureacontainerthatwillrunasanexecutable
运行一个docker容器像运行一个程序一样
entrypoint的使用方法:
1.entrypoint["executable","param1","param2"](thepreferredexecform)
推荐使用1方法,启动起来后,pid为1
2.entrypointcommandparam1param2(shellform)
启动起来后,pid号为shell命令执行完的pid号
cmd解析
cmd的使用方法:
1.cmd["executable","param1","param2"](execform,thisisthepreferredform)
运行一个可执行的文件并提供参数
2.cmd["param1","param2"](asdefaultparameterstoentrypoint)
为entrypoint指定参数
3.cmdcommandparam1param2(shellform)
是以”/bin/sh-c”的方法执行的命令
实战测试cmd
vimdockerfilefromcentos:centos7.1.1503cmd["/bin/echo","thisistestcmd"]
生成cmd镜像dockerbuild-tcsphere/cmd:0.1.生成cmd容器,进行测试dockerrun-it--rmcsphere/cmd:0.1thisistestcmd测试是否可以替换cmd的命令dockerrun-itcsphere/cmd:0.1/bin/bash[root@c1963a366319/]#
测试结果,在dockerfile中定义的cmd命令,在执行dockerrun的时候,cmd命令可以被替换。
实战测试entrypoint
fromcentos:centos7.1.1503entrypoint["/bin/echo","thisistestentrypoint"]
生成ent(entrypoint)镜像dockerbuild-tcsphere/ent:0.1.
生成ent容器,进行测试dockerrun-itcsphere/ent:0.1thisistestentrypoint测试是否可以替换entrypoint的命令dockerrun-itcsphere/ent:0.1/bin/bashthisistestentrypoint/bin/bash
测试结果,在dockerfile定义的entrypoint命令,通过以上方式不能被替换
实战再次测试entrypoint
