适用于sealos的方案

[flt6]

修改自docker

镜像：nginx
CPU和内存拉到最小
网络配置：暴露80开启公网访问

高级配置：

启动命令：/bin/bash
运行参数：/app/start.sh
环境变量：

HOSTNAME=公网访问处显示的地址
PASSWORD=自己设的密码
CONTEXT_PATH=自己设随机字符串
SSL_CERTIFICATE=/app/ssl/cert.crt
SSL_CERTIFICATE_KEY=/app/ssl/cert.key

配置文件：

• /app/ssl/cert.crt 内容任意
• /app/ssl/cert.key 内容任意
• /app/start.sh 和docker相同

cp -f  '/etc/nginx/nginx-template.conf' '/etc/nginx/nginx.conf'
sed -i 's#${SSL_CERTIFICATE}#'"$SSL_CERTIFICATE"'#g' '/etc/nginx/nginx.conf'
sed -i 's#${SSL_CERTIFICATE_KEY}#'"$SSL_CERTIFICATE_KEY"'#g' '/etc/nginx/nginx.conf'
sed -i 's#${HOSTNAME}#'"$HOSTNAME"'#g' '/etc/nginx/nginx.conf'
sed -i 's#${PASSWORD}#'"$PASSWORD"'#g' '/etc/nginx/nginx.conf'
sed -i 's#${CONTEXT_PATH}#'"$CONTEXT_PATH"'#g' '/etc/nginx/nginx.conf'
nginx -g 'daemon off;'
