The openresty docker image of reload can be created automatically according to the change of configuration file.

1. Create a working directory

Mkdir openresty & & cd openresty2. Write a script that uses inotify to monitor configuration file changes and automatically reload auto-reload.sh:

#! / bin/shinotifywait-e modify,move,create,delete-mr-- timefmt'% d/%m/%y% HV% 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 reloaddone3. Write the image startup script start.sh:

#! / bin/bash/usr/bin/openresty-g "daemon off;" & / auto-reload.sh4. Write the configuration file nginx.conf:

User nobody;worker_processes auto;#worker_cpu_affinity 01 10 http workers are responsible for events {use epoll; worker_connections 6000;} 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 48k; 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 500502503504 / 50x.htl; location = / 50x.html {root html;}} 5. Write a 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. Execute the docker build command:

Docker build-t openresty:1.15.8.2-f. / dockerfile. After the above command is executed, you can see the newly created openresty image through docker images.

7. Verify and run the container with the following command:

Docker run-itd-p 8080 data/logs:/usr/local/openresty/nginx/logs 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 adds or modifies the configuration file in the host directory / data/nginx/conf.d, and the openresty in the container will automatically reload, and the image will be created successfully.
