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/sh
inotifywait -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 "$event"
/usr/local/openresty/nginx/sbin/nginx -s reload
done
3. 编写镜像启动脚本start.sh:
#!/bin/bash
/usr/bin/openresty -g "daemon off;" &
/auto-reload.sh
4. 编写配置文件nginx.conf:
user nobody;
worker_processes auto;
#worker_cpu_affinity 01 10;
worker_rlimit_nofile 65535;
events {
use epoll;
worker_connections 60000;
}
http {
include mime.types;
default_type application/octet-stream;
tcp_nodelay on;
log_format main '$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 <xxx@xxx.com>
ADD auto-reload.sh auto-reload.sh
ADD start.sh start.sh
RUN 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.sh
ADD nginx.conf /usr/local/openresty/nginx/conf/nginx.conf
EXPOSE 80
EXPOSE 443
CMD ["./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。
