07容器与自动化第03章构建ker实战

1、第 03 章：构建 Docker 容器实战一：案例-构建 nginx 容器1：将 centos 镜像导入到 docker 中rootlocalhost # docker load -inpentos7.3.tard69483a6face: Loading layer209.5MB/209.5MBLoaded image: centos:latest2：创建 dockerfile 工作目录rootlocalhost # mkdir /opt/nginx rootlocalhost # cd /opt/nginx3：创建 dockerfilerootlocalhost nginx# vim doc

2、kerfile FROM centosRUN rm -rf /etc/yum.re.d/*ADD my163.repo /etc/yum.re.d/myrepo.repoRUN yum clel#RUN yum makecacheRUN yum -y install pcre-devel zlib-devel zlib gcc* make openssl-devel ADD nginx-1.12.0.tar.gz /optWORKDIR /opt/nginx-1.12.0RUN ./configure -prefix=/usr/local/nginx & make & make install

3、EXEXE 80E 443RUN echo daemon off;/usr/local/nginx/conf/nginx.conf#WORKDIR /root/nginx ADD run.sh /run.shRUNod 775 /run.shCMD /run.sh注释：使用 ADD 想容器添加压缩包时，在容器中会自动解压，使用COPY 则不会4：将 163 的 yum 源文件拷贝到 dockerfile 的 nginx 目录中5：编写 nginx 启动rootlocalhost nginx# vim run.sh #!/bin/bash/usr/local/nginx/sbin/nginx6：

4、用 dockerfile 创建镜像rootlocalhost nginx# docker build -t mynginx .7：启动容器rootlocalhost nginx# docker run -d -i -p 8080:80 mynginx注意：此处不带-t 选项，容器中有一个 run.sh 的或者，带上-t 选项，这个就不执行了rootlocalhost nginx# docker run -d -it -p 8080:80 mynginx /bin/bash -c /run.sh此处使用 bash 执行 run.sh 的另一种启动方法rootlocalhost nginx# do

5、cker run -d -i -v /nginx/conf/nginx.conf:/usr/local/nginx/conf/nginx.conf -v/nginx/html/:/usr/local/nginx/html/ -p 80:80 mynginx002注释：这个方法是将本机上的配置文件挂在到容器中，将本机的目录挂在到容器中需要提前在挂在配置文件的目录下存在 nginx 的配置文件，这样就可以不进入容器，直接在主机上修改配置文件了8：nginx二：案例构建 Tomcat 容器1：创建工作目录rootlocalhost # mkdir /opt/tomcat/ rootlocalhost

6、 # cd /opt/tomcat/2：将 jdk 解压，并移动到工作目录rootlocalhost # tar zxvf jdk-8u91-linux-x64.tar.gz -C /opt/tomcat/3：创建 dockerfile 文件rootlocalhost tomcat# vim dockerfileFROM centosADD jdk1.8.0_91 /usr/local/jdk-8u91ENV JAVA_HOME /usr/local/jdk-8u91ENV JAVA_BIN /usr/local/jdk-8u91 ENV JRE_HOME /usr/local/jdk-8u9

8、run.sh4：创建启动rootlocalhost tomcat# vim run.sh #!/bin/bash/usr/local/tomcat/bin/startup.shtailf /run5：用 dockerfile 生成镜像rootlocalhost tomcat# docker build -t mytomcat .6：运行容器rootlocalhost tomcat# docker run -d -i -p 8080:8080 mytomcat7：tomcat三：案例-构建容器1：创建工作目录rootlocalhost # mkdir /opt/2：创建 dockerfile 文
