构建nginxDockerfile镜像

这里的nginx软件包使用nginx-1.12.2.tar.gz需要的私聊

[root@docker ~]# mkdir /nginx [root@docker ~]# cd /nginx/ [root@docker nginx]# vim Dockerfile FROM centos:7 RUN yum update -y RUN yum -y install gcc gcc-c++ make pcre-devel expat-devel perl zlib-devel pcre RUN useradd -M -s /sbin/nologin nginx ADD nginx-1.12.2.tar.gz /usr/local WORKDIR /usr/local/nginx-1.12.2 RUN (./configure --prefix=/usr/local/nginx --user=nginx --group=nginx --with-http_stub_status_module) && make && make install ENV PATH /usr/local/nginx/sbin/:$PATH EXPOSE 80 EXPOSE 443 RUN echo "daemon off;" >> /usr/local/nginx/conf/nginx.conf '关闭nginx自带的守护进程' CMD ["/usr/local/nginx/sbin/nginx"] 这里指定的是在centos7下安装 要指定版本 [root@docker nginx]# rz -E '//上传nginx源码包' rz waiting to receive. [root@docker nginx]# ls Dockerfile nginx-1.12.2.tar.gz [root@docker nginx]# docker build -t nginx:test . [root@docker nginx]# docker run -d -P nginx:test1 885cf9811be57e12690ce352fbd7c5011cefffece8b59a0d7317e12eb8955a70 [root@docker nginx]# docker ps -a CONTAINER ID IMAGE COMMAND CREATED STATUS PORTS NAMES e34b0c nginx:test1 "/usr/local/nginx/sb…" 2 minutes ago Up 2 minutes 0.0.0.0:32784->22/tcp, 0.0.0.0:32783->80/tcp, 0.0.0.0:32782->443/tcp zen_hellman 

创建容器，指定端口

[root@docker nginx]# docker run -d -P nginx:test1 885cf9811be57e12690ce352fbd7c5011cefffece8b59a0d7317e12eb8955a70 [root@docker nginx]# docker ps -a CONTAINER ID IMAGE COMMAND CREATED STATUS PORTS NAMES e34b0c nginx:test1 "/usr/local/nginx/sb…" 2 minutes ago Up 2 minutes 0.0.0.0:32784->22/tcp, 0.0.0.0:32783->80/tcp, 0.0.0.0:32782->443/tcp zen_hellman [root@docker nginx]# ip addr '//自己IP地址为 192.168.233.133' 1: lo: <LOOPBACK,UP,LOWER_UP> mtu 65536 qdisc noqueue state UNKNOWN group default qlen 1000 link/loopback 00:00:00:00:00:00 brd 00:00:00:00:00:00 inet 127.0.0.1/8 scope host lo valid_lft forever preferred_lft forever inet6 ::1/128 scope host valid_lft forever preferred_lft forever 2: ens33: <BROADCAST,MULTICAST,UP,LOWER_UP> mtu 1500 qdisc pfifo_fast state UP group default qlen 1000 link/ether 00:0c:29:68:b8:a6 brd ff:ff:ff:ff:ff:ff inet 192.168.233.133/24 brd 192.168.233.255 scope global noprefixroute ens33 valid_lft forever preferred_lft forever inet6 fe80::35a9:b12:5e2b:c44d/64 scope link noprefixroute valid_lft forever preferred_lft forever ...省略内容 

构建DockerfileTomcat

[root@docker nginx]# mkdir /tomcat [root@docker nginx]# cd /tomcat/ [root@docker tomcat]# vim Dockerfile FROM centos MAINTAINER this is tomcat ADD jdk-8u201-linux-x64.rpm /usr/local/ WORKDIR /usr/local/ RUN rpm -ivh jdk-8u201-linux-x64.rpm ENV JAVA_HOME /usr/java/jdk1.8.0_201-amd64 ENV CLASSPATH $JAVA_HOME/lib/tools.jar:$JAVA_HOME/lib/dt.jar ENV PATH $JAVA_HOME/bin:$PATH ADD apache-tomcat-9.0.16.tar.gz /usr/local WORKDIR /usr/local RUN mv apache-tomcat-9.0.16/ /usr/local/tomcat9 ENV PATH /usr/local/tomcat9/bin/:$PATH EXPOSE 8080 ENTRYPOINT ["/usr/local/tomcat9/bin/catalina.sh","run"] [root@docker tomcat]# docker build -t tomcat:test . '创建镜像' [root@docker tomcat]# docker run -d -P tomcat:test '启动镜像' [root@docker tomcat]# docker ps -a |grep tomcat f4afd19d14d3 tomcat:test1 "/usr/local/src/tomc…" 25 seconds ago Up 23 seconds 0.0.0.0:32788->22/tcp, 0.0.0.0:32787->8080/tcp lucid_tesla 

1、ENRYPOINT指开启容器前镜像就已经执行了括号内的命令

2、CMD是开启容器时，要执行的指令，设置容器启动后默认执行的命令及其参数，但 CMD 能够被 docker run 后面跟的命令行参数替换

3、基于Dockerfile内有CMD或者ENTRYPOINT创建镜像时，docker run 后面就不要加指令(/bin/bash)了，会覆盖掉Dockerfile中的指令或者语法报错
