可根据配置文件变化自动reload的openresty docker镜像制作

1. 创建工作目录

mkdir openresty && cd openresty

2. 编写使用inotify监控配置文件变化并自动reload的脚本auto-reload.sh：

#!/bin/shinotifywait -e modify,move,create,delete -mr --timefmt '%d/%m/%y %H:%M' --format '%T %f %e' \/usr/local/openresty/nginx/conf/conf.d | while read event; do    echo "$event"    /usr/local/openresty/nginx/sbin/nginx -s reloaddone

3. 编写镜像启动脚本start.sh：

#!/bin/bash/usr/bin/openresty -g "daemon off;" &/auto-reload.sh

4. 编写配置文件nginx.conf：

user nobody;worker_processes  auto;#worker_cpu_affinity 01 10;worker_rlimit_nofile 65535;events {    use epoll;    worker_connections  60000;}http {    include       mime.types;    default_type  application/octet-stream;    tcp_nodelay   on;    log_format  main  '$status $host $remote_addr $request_time - '                      '$upstream_status $upstream_addr $upstream_response_time '                      '[$time_local] $request '                      '$bytes_sent $body_bytes_sent "$http_referer" '                      '"$http_user_agent" "$http_x_forwarded_for"';    access_log /usr/local/openresty/nginx/logs/access.log main;    error_log /usr/local/openresty/nginx/logs/error.log;    log_not_found  off;    sendfile        on;    keepalive_timeout  15;    server_names_hash_bucket_size 4096;    client_header_buffer_size 16k;    large_client_header_buffers 4 64k;    gzip on;    gzip_http_version 1.0;    gzip_proxied     expired no-cache no-store private auth;    gzip_types       text/plain application/x-javascript text/css  application/xml text/javascript;    gzip_min_length  1000;    gzip_comp_level 5;    gzip_buffers    4 8k;    gzip_disable "MSIE [1-6]\.(?!.*SV1)";    include localenv.d/*.conf;    include env.d/*.conf;    include conf.d/*.backend.cfg;    include conf.d/*.server.cfg;    server {        listen       80;        server_name  localhost;        #access_log  logs/host.access.log  main;        location / {            root   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   html;        }    }}

5. 编写dockerfile：

FROM centos:7.6.1810 MAINTAINER openresty1.15.8.2  ADD auto-reload.sh auto-reload.shADD start.sh start.shRUN yum -y install epel-release && yum install inotify-tools -y && yum install -y yum-utils && yum-config-manager --add-repo https://openresty.org/package/centos/openresty.repo && yum install -y openresty && yum clean all && chmod +x start.sh && chmod +x auto-reload.shADD nginx.conf /usr/local/openresty/nginx/conf/nginx.confEXPOSE 80EXPOSE 443CMD ["./start.sh"]

6. 执行docker build命令：

docker build -t openresty:1.15.8.2 -f ./dockerfile .

上述命令执行完后，就可以通过docker images看到刚制作好的openresty镜像了

7. 验证，用以下命令运行容器：

docker run -itd -p 8080:80 -v /data/logs:/usr/local/openresty/nginx/logs -v /data/nginx/conf.d:/usr/local/openresty/nginx/conf/conf.d openresty:1.15.8.2

在宿主机目录/data/nginx/conf.d下新增或修改配置文件，容器中的openresty会自动reload，镜像制作成功。
