Docker 安裝 Nginx

方法1、docker pull nginx(推薦)

查找 Docker Hub 上的 nginx 鏡像php

runoob@runoob:~/nginx$ docker search nginx

 這裏咱們拉取官方的鏡像nginx

runoob@runoob:~/nginx$ docker pull nginx

 等待下載完成後，咱們就能夠在本地鏡像列表裏查到 REPOSITORY 爲 nginx 的鏡像。web

runoob@runoob:~/nginx$ docker images nginx
REPOSITORY          TAG                 IMAGE ID            CREATED             SIZE
nginx               latest              555bbd91e13c        3 days ago          182.8 MB

方法2、經過 Dockerfile 構建(不推薦)

建立 Dockerfiledocker

首先，建立目錄 nginx, 用於存放後面的相關東西。ubuntu

runoob@runoob:~$ mkdir -p ~/nginx/www ~/nginx/logs ~/nginx/conf

www: 目錄將映射爲 nginx 容器配置的虛擬目錄。瀏覽器

logs: 目錄將映射爲 nginx 容器的日誌目錄。tomcat

conf: 目錄裏的配置文件將映射爲 nginx 容器的配置文件。app

進入建立的 nginx 目錄，建立 Dockerfile 文件，內容以下：tcp

FROM debian:stretch-slim

LABEL maintainer="NGINX Docker Maintainers <docker-maint@nginx.com>"

ENV NGINX_VERSION 1.14.0-1~stretch
ENV NJS_VERSION   1.14.0.0.2.0-1~stretch

        echo "Fetching GPG key $NGINX_GPGKEY from $server"; \
        apt-key adv --keyserver "$server" --keyserver-options timeout=10 --recv-keys "$NGINX_GPGKEY" && found=yes && break; \

    test -z "$found" && echo >&2 "error: failed to fetch GPG key $NGINX_GPGKEY" && exit 1; \

            && ( \

                && DEB_BUILD_OPTIONS="nocheck parallel=$(nproc)" \
                    apt-get source --compile $nginxPackages \
            ) \
# we don't remove APT lists here because they get re-downloaded and removed later
            \
# reset apt-mark's "manual" list so that "purge --auto-remove" will remove all build dependencies
# (which is done after we install the built packages so we don't have to redownload any overlapping dependencies)
            && apt-mark showmanual | xargs apt-mark auto > /dev/null \
            && { [ -z "$savedAptMark" ] || apt-mark manual $savedAptMark; } \
            \

            && ls -lAFh "$tempDir" \
            && ( cd "$tempDir" && dpkg-scanpackages . > Packages ) \

# forward request and error logs to docker log collector
RUN ln -sf /dev/stdout /var/log/nginx/access.log \
    && ln -sf /dev/stderr /var/log/nginx/error.log

EXPOSE 80

STOPSIGNAL SIGTERM

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

 經過 Dockerfile 建立一個鏡像，替換成你本身的名字。php-fpm

docker build -t nginx .

 建立完成後，咱們能夠在本地的鏡像列表裏查找到剛剛建立的鏡像

runoob@runoob:~/nginx$ docker images nginx
REPOSITORY          TAG                 IMAGE ID            CREATED             SIZE
nginx               latest              555bbd91e13c        3 days ago          182.8 MB

使用 nginx 鏡像

運行容器

runoob@runoob:~/nginx$ docker run -p 80:80 --name mynginx -v $PWD/www:/www -v $PWD/conf/nginx.conf:/etc/nginx/nginx.conf -v $PWD/logs:/wwwlogs  -d nginx  
45c89fab0bf9ad643bc7ab571f3ccd65379b844498f54a7c8a4e7ca1dc3a2c1e
runoob@runoob:~/nginx$

命令說明：

  • -p 80:80：將容器的80端口映射到主機的80端口

  • --name mynginx：將容器命名爲mynginx

  • -v $PWD/www:/www：將主機中當前目錄下的www掛載到容器的/www

  • -v $PWD/conf/nginx.conf:/etc/nginx/nginx.conf：將主機中當前目錄下的nginx.conf掛載到容器的/etc/nginx/nginx.conf

  • -v $PWD/logs:/wwwlogs：將主機中當前目錄下的logs掛載到容器的/wwwlogs

查看容器啓動狀況

runoob@runoob:~/nginx$ docker ps
CONTAINER ID        IMAGE        COMMAND                      PORTS                         NAMES
45c89fab0bf9        nginx        "nginx -g 'daemon off"  ...  0.0.0.0:80->80/tcp, 443/tcp   mynginx
f2fa96138d71        tomcat       "catalina.sh run"       ...  0.0.0.0:81->8080/tcp          tomcat
