Dockerfile

———————————————————————————————————————

首先需要的包和dockerfile放在一起

[root@localhost docker-file]# ls

Dockerfile nginx-1.9.3.tar.gz pcre-8.37.tar.gz

[root@localhost docker-file]# pwd

/opt/docker-file

[root@localhost docker-file]#

———————————————————————————————————————

建立dockerfile

[root@localhost docker-file]# vim Dockerfile

#base images,name or id 可以是映象名字或者映象ID

FROM 3bee3060bfc8

#add 把包新增到容器的指定目錄，如果是tar包會自動解壓

ADD pcre-8.37.tar.gz /usr/local/src

ADD nginx-1.9.3.tar.gz /usr/local/src

#run 在容器裡執行命令安裝nginx需要軟體

RUN yum install -y wget gcc gcc-c++ make openssl-devel

#run 在容器裡執行命令建立使用者

RUN useradd -s /sbin/nologin -M www

#workdir 相當於cd到這個目錄

WORKDIR /usr/local/src/nginx-1.9.3

#run 在容器裡執行命令進行編譯安裝

RUN ./configure –prefix=/usr/local/nginx –user=www –group=www –with-http_ssl_module –with-http_stub_status_module –with-pcre=/usr/local/src/pcre-8.37 && make && make install

#run 在容器裡執行命令更改nginx配置檔案，使其前臺執行

RUN echo “daemon off;” >> /usr/local/nginx/conf/nginx.conf

#env 將nginx啟動命令加到環境變數裡

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

#對映80埠

EXPOSE 80

執行nginx命令

CMD [“nginx”]

———————————————————————————————————————

執行dockerfile

[root@localhost docker-file]# docker build -t my-nginx-1:v1 /opt/docker-file/

當成功後會出現這個，說明執行成功

Successfully built 21273b8e163a

———————————————————————————————————————

檢視映象

[root@localhost docker-file]# docker images

REPOSITORY TAG IMAGE ID CREATED SIZE

my-nginx-1 v1 21273b8e163a 14 minutes ago 429.1 MB

———————————————————————————————————————

使用建立好的映象啟動容器

[root@localhost docker-file]# docker run -dit –name mynginx 21273b8e163a

———————————————————————————————————————

檢視執行的容器

[root@localhost docker-file]# docker ps

CONTAINER ID IMAGE COMMAND CREATED STATUS PORTS NAMES

aa30accbfc06 21273b8e163a “nginx” 3 seconds ago Up 2 seconds 80/tcp mynginx

———————————————————————————————————————

訪問這個容器的80埠，看nginx是否安裝啟動成功

[root@localhost docker-file]# curl 172.17.0.3
