Dockerfile安装源码nginx

一、准备工作

1、下载基础镜像

[root@localhost ~]# docker pull centos
[root@localhost ~]# docker images
REPOSITORY          TAG                 IMAGE ID            CREATED             SIZE
centos              latest              9f38484d220f        2 months ago        202MB

2、创建存放nginx的目录和Dockerfile文件（注意Dockerfile的D需要大写）

[root@localhost ~]# mkdir docker_nginx
[root@localhost ~]# cd docker_nginx/
[root@localhost docker_nginx]# touch Dockerfile
[root@localhost docker_nginx]# pwd
/root/docker_nginx
[root@localhost docker_nginx]# ll
total 0
-rw-r--r-- 1 root root 0 Jun 14 02:48 Dockerfile

3、下载nginx源码包到docker_nginx目录下

[root@localhost docker_nginx]# wget http://nginx.org/download/nginx-1.12.2.tar.gz

二、编写Dockerfile

1、配置文件，注意添加daemon off;不是以守护进程启动，否则进程进行完成会自动关闭，容器无法再访问

[root@localhost docker_nginx]# cat Dockerfile 
FROM centos

MAINTAINER [email protected]

ADD nginx-1.12.2.tar.gz /usr/local/src

RUN yum install -y gcc gcc-c++  glibc make autoconf openssl openssl-devel
RUN yum install -y libxslt-devel -y gd gd-devel GeoIP GeoIP-devel pcre pcre-devel
RUN useradd -M -s /sbin/nologin nginx

WORKDIR /usr/local/src/nginx-1.12.2

RUN ./configure --user=nginx --group=nginx --prefix=/usr/local/nginx && make && make install

ENV PATH /usr/local/nginx/sbin:$PATH

EXPOSE 80

ENTRYPOINT ["nginx"]

CMD ["-g","daemon off;"]

2、查看docker_nginx目录情况

[root@localhost docker_nginx]# pwd
/root/docker_nginx
[root@localhost docker_nginx]# ll
total 964
-rw-r--r-- 1 root root    509 Jun 14 03:17 Dockerfile
-rw-r--r-- 1 root root 981687 Oct 17  2017 nginx-1.12.2.tar.gz

3、执行docker build进行构建

[root@localhost docker_nginx]# docker build -t centos_nginx:v1 .

4、构建成功提示，并查看

Removing intermediate container 9976df44f135
Successfully built 18be94a7553b
[root@localhost docker_nginx]# docker images
REPOSITORY          TAG                 IMAGE ID            CREATED             SIZE
centos_nginx        v1                  18be94a7553b        4 minutes ago       524 MB

三、启动新镜像并映射端口到宿主机

1、-d后台运行，-p指定端口

[root@localhost docker_nginx]# docker run -d -p 80:80 centos_nginx:v1 
80c508a81a1b2d5f9ecbd6359d16652e1f0c7d8b4cff19035e49351ba84b3921

2、查看容器，可以看到映射端口

[root@localhost docker_nginx]# docker ps -a
CONTAINER ID        IMAGE               COMMAND                  CREATED             STATUS              PORTS                NAMES
80c508a81a1b        centos_nginx:v1     "nginx -g 'daemon ..."   20 seconds ago      Up 19 seconds       0.0.0.0:80->80/tcp   ecstatic_clarke

3、容器名称更改:rename  旧名称 新名称

[root@localhost docker_nginx]# docker rename ecstatic_clarke nginx_v1
[root@localhost docker_nginx]# docker ps -a
CONTAINER ID        IMAGE               COMMAND                  CREATED             STATUS              PORTS                NAMES
80c508a81a1b        centos_nginx:v1     "nginx -g 'daemon ..."   7 minutes ago       Up 7 minutes        0.0.0.0:80->80/tcp   nginx_v1

4、网页访问
