docker-compose快速部署nginx

一、概述

bitnami镜像

https://registry.hub.docker.com/r/bitnami/nginx

准备

目前docker-compose创建nginx脚本不支持直接挂载文件，只能挂载文件夹，通常我们需要挂载nginx.conf文件，所以必须先在宿主机上生成同名文件。

# 先用docker创建nginx，复制对应文件
mkdir -p nginx/conf nginx/conf.d && cd nginx
docker run --name nginx-demo -d nginx
# 复制文件
docker cp nginx-demo:/etc/nginx/nginx.conf ./conf/nginx.conf
docker cp nginx-demo:/etc/nginx/conf.d/default.conf ./conf.d/default.conf
docker cp nginx-demo:/usr/share/nginx/html .
# 删除容器
docker stop nginx-demo && docker rm nginx-demo

否则报错：

[root@VM_80_127_linux nginx]# docker-compose up -d 
Starting nginx ... error

二、docker-compose

vim docker-compose.yml

version: '3.1'

services:
  nginx:
    image: nginx
    container_name: nginx
    environment:
      - TZ=Asia/Shanghai
    ports:
      - 11086:11086
    volumes:
      - ./conf.d:/etc/nginx/conf.d
      - ./conf/nginx.conf:/etc/nginx/nginx.conf
      - ./logs:/var/log/nginx
      - ./html:/etc/nginx/html
