1、下载alpine镜像

[root@docker43 ~]# docker pull alpine
Using default tag: latest
Trying to pull repository docker.io/library/alpine ...
latest: Pulling from docker.io/library/alpine
4fe2ade4980c: Pull complete
Digest: sha256:621c2f39f8133acb8e64023a94dbdf0d5ca81896102b9e57c0dc184cadaf5528
Status: Downloaded newer image for docker.io/alpine:latest
[root@docker43 ~]# docker images
REPOSITORY TAG IMAGE ID CREATED SIZE
docker.io/alpine latest 196d12cf6ab1 3 weeks ago 4.41 MB

2、编写dockerfile(一)

2.1.创建存放文件目录

[root@docker43 ~]# cd /opt/
[root@docker43 opt]# mkdir alpine_nginx && cd alpine_nginx && touch Dockerfile && touch nginx.conf && touch nginx.vh.default.conf
[root@docker43 alpine_nginx]# ll
总用量 16
-rw-r--r-- 1 root root 5652 10月 4 18:15 Dockerfile
-rw-r--r-- 1 root root 638 10月 4 15:23 nginx.conf
-rw-r--r-- 1 root root 472 10月 4 15:24 nginx.vh.default.conf

2.2. 准备nginx.conf文件

[root@docker43 alpine_nginx]# cat nginx.conf
user nginx;
worker_processes 1;
error_log /var/log/nginx/error.log warn;
pid /var/run/nginx.pid;
events {
worker_connections 10240;
}
http {
include /etc/nginx/mime.types;
default_type application/octet-stream; log_format main '$remote_addr - $remote_user [$time_local] "$request" '
'$status $body_bytes_sent "$http_referer" '
'"$http_user_agent" "$http_x_forwarded_for"'; access_log /var/log/nginx/access.log main; sendfile on;
#tcp_nopush on; keepalive_timeout 65; #gzip on; include /etc/nginx/conf.d/*.conf;
}

2.3.准备nginx.vh.default.conf文件

[root@docker43 alpine_nginx]# cat nginx.vh.default.conf
server {
listen 80;
server_name localhost; #charset koi8-r;
#access_log /var/log/nginx/log/host.access.log main; location / {
root /usr/share/nginx/html;
index index.html index.htm;
} #error_page 404 /404.html; # redirect server error pages to the static page /50x.html
#
error_page 500 502 503 504 /50x.html;
location = /50x.html {
root /usr/share/nginx/html;
}
}

2.4.dockerfile文件

2.5.创建镜像

[root@docker43 alpine_nginx]# docker build -t alpine:nginx .

2.6.创建容器

# 不进行宿主配置文件日志文件挂载
docker run -tid --name zjznginx -p 80:80 -m 2048m --memory-swap=2048m --cpu-shares=256 alpine:nginx # 挂载配置文件和日志
docker run -tid --name zjznginx -p 80:80 -v /opt/Webs/nginx/nginx.conf:/etc/nginx/nginx.conf -v /opt/Webs/nginx/logs/:/var/log/nginx -m 2048m --memory-swap=2048m --cpu-shares=256 alpine:nginx

查看容器

3、编写dockerfile(二)

3.1.创建存放文件目录

[root@docker43 ~]# cd /opt/
[root@docker43 opt]# mkdir alpine_nginx && cd alpine_nginx && touch Dockerfile && touch nginx.conf && touch nginx.vh.default.conf
[root@docker43 alpine_nginx]# ll

-rw-r--r-- 1 root root 472 10月 4 15:24 nginx.vh.default.conf

3.2.准备nginx.conf文件

[root@docker43 alpine_nginx]# cat nginx.conf
user nginx;
worker_processes 1;
error_log /var/log/nginx/error.log warn;
pid /var/run/nginx.pid;
events {
worker_connections 10240;

#tcp_nopush on; keepalive_timeout 65; #gzip on; include /etc/nginx/conf.d/*.conf;
}

3.3. 准备nginx.vh.default.conf文件

[root@docker43 alpine_nginx]# cat nginx.vh.default.conf
server {
listen 80;
server_name localhost; #charset koi8-r;
#access_log /var/log/nginx/log/host.access.log main; location / {

3.5.创建镜像

[root@docker43 alpine_nginx]# docker build -t alpine:nginx .

3.6.创建容器

# 不进行宿主配置文件日志文件挂载
docker run -ti --restart=always --name zjznginx -p 80:80 -m 2048m --memory-swap=2048m --cpu-shares=256 alpine:nginx bash # 挂载配置文件和日志
docker run -ti --restart=always --name zjznginx -p 80:80 -v /opt/Webs/nginx/nginx.conf:/etc/nginx/nginx.conf -v /opt/Webs/nginx/logs/:/var/log/nginx -m 2048m --memory-swap=2048m --cpu-shares=256 alpine:nginx bash

PS:因为用的是脚本命令的方式启动的,没有守护进程 ,最后使用bash或者sh进入容器启动然后ctrl+p ctrl+q 退出

具体的解释:docker运行nginx为什么要使用 daemon off

启动nginx

[root@docker43 alpine_nginx]# docker run -ti --restart=always --name zjznginx  -p 80:80 -m 2048m  --memory-swap=2048m  --cpu-shares=256 alpine:nginx bash
bash-4.4# /bin/sh /etc/start.sh

查看容器
