Docker 安装 Nginx
Docker 安装 Nginx
标签（空格分隔）： Docker nginx
在docker中创建镜像有两种方式:一:使用Dockfile文件创建;二:从Docker hub 镜像仓库拉取.
就像我们在 史上最简单的Docker入门教程中了解的那样:
为了简单起见,像这种常见的容器,我们没必要从新写Dockerfile文件去创建image文件.直接使用docker image pull从docker hub拉取一个就可以.
第一步:搜索
首先通过 docker search [imageName] 命令搜索一下docker hub有没有我们想要的镜像.
ig:~ itguang$ docker search nginx

ig:~ itguang$NAME:镜像仓库源的名称
DESCRIPTION:镜像的描述
STARS: 点赞数
OFFICIAL:是否docker官方发布
第二步:拉取
接下来我们使用 docker pull [imageName]命令拉取我们想要的镜像:
ig:~ itguang$ docker pull nginx
Using default tag: latest
latest: Pulling from library/nginx
f2aa67a397c4: Pull complete
3c091c23e29d: Pull complete
4a99993b8636: Pull complete
Digest: sha256:0fb320e2a1b1620b4905facb3447e3d84ad36da0b2c8aa8fe3a5a81d1187b884
Status: Downloaded newer image for nginx:latest
ig:~ itguang$拉取完毕,使用 docker images或者docker image ls命令查看当前镜像文件:
ig:~ itguang$ docker images
REPOSITORY TAG IMAGE ID CREATED SIZE
nginx latest ae513a47849c 7 days ago 109MB
ig:~ itguang$ docker image ls
REPOSITORY TAG IMAGE ID CREATED SIZE
nginx latest ae513a47849c 7 days ago 109MB
ig:~ itguang$第三步:使用nginx镜像
运行容器:
首先我们现在当前目录创建几个目录
$PWD/www:/www
$PWD/logs
$PWD/conf/nginx.conf接下来运行下面的命令
ig:nginx itguang$ docker run -p 8000:80 --name mynginx -v $PWD/www:/www -v $PWD/conf/nginx.conf:/etc/nginx/nginx.conf -v $PWD/logs:/wwwlogs -d nginx
ad6de61641e02bfcec56a44c2ba51c4f42f9e4bb47d0c3ca67390d4d4676c750
ig:nginx itguang$
解释一下上面的参数:
-p 8000:80：将容器的80端口映射到主机的80端口.
–name mynginx: 将容器命名为 mynginx.
-v $PWD/www:/www: 将主机当前目录下的www目录挂在到容器的/www目录下.
-v $PWD/logs:/wwwlogs: 将主机当前目录下的logs目录挂在到容器的/wwwlogs目录下
-v $PWD/conf/nginx.conf:/etc/nginx/nginx.conf:将主机当前目录下的nginx.conf挂在到容器目录下的etc/nginx/nginx.conf 文件.
-d nginx: 后台运行nginx容器,并且打印containerID.
使用docker ps或者docker container ls
ig:~ itguang$ docker ps
CONTAINER ID IMAGE COMMAND CREATED STATUS PORTS NAMES
e8c8fae59eaf nginx "nginx -g 'daemon of…" About a minute ago Up About a minute 0.0.0.0:8000->80/tcp mynginx
ig:~ itguang$测试: 浏览器访问 : http://172.18.21.142:8000/
可以看到nginx的欢迎页,证明docker安装nginx容器已经成功.
