我需要一个基于nginx:alpine的Docker容器,该容器从端口8080提供HTTP内容,但是默认情况下nginx:alpine会在端口80上进行监听。
构建自定义容器时如何更改端口?
答案 0 :(得分:3)
选项1(推荐):设置新的配置文件
创建具有以下内容的本地 default.conf * 文件:
server {
listen 8080;
server_name localhost;
location / {
root /usr/share/nginx/html;
index index.html index.htm;
}
# redirect server error pages to the static page /50x.html
#
error_page 500 502 503 504 /50x.html;
location = /50x.html {
root /usr/share/nginx/html;
}
}
*超出端口8080,根据您的需要自定义上述内容
将 default.conf 复制到自定义容器[Dockerfile]:
FROM nginx:alpine
## Copy a new configuration file setting listen port to 8080
COPY ./default.conf /etc/nginx/conf.d/
EXPOSE 8080
CMD ["nginx", "-g", "daemon off;"]
选项2:更改nginx默认配置[Dockerfile]
FROM nginx:alpine
## Make a copy of default configuration file and change listen port to 8080
RUN cp /etc/nginx/conf.d/default.conf /etc/nginx/conf.d/default.conf.orig && \
sed -i 's/listen[[:space:]]*80;/listen 8080;/g' /etc/nginx/conf.d/default.conf
EXPOSE 8080
CMD ["nginx", "-g", "daemon off;"]
当然,备份原始配置是可选的
