修改 nginx 配置文件

如果要更新nginx根配置，您将使用错误的Docker目录进行挂载。

Nginx配置文件

Docker工具会安装自己的nginx.conf文件。如果您想要直接覆盖它，可以在自己的Dockerfile中或通过卷绑定挂载来替换它。

对于Linux映像，该nginx.conf具有包含/etc/nginx/conf.d/*.conf指令;因此，该目录中的所有nginx配置都将包括在内。默认虚拟主机配置具有原始的OpenResty配置，并被复制到/etc/nginx/conf.d/default.conf中。

docker run -v /my/custom/conf.d:/etc/nginx/conf.d openresty/openresty:alpine

其次，最好使用绝对路径进行挂载。

docker run -v $PWD/conf/nginx.conf:/etc/nginx/nginx.conf openresty/openresty:1.15.8.2-1-alpine

或者

docker run -v abs_path/nginx.conf:/etc/nginx/nginx.conf openresty/openresty:1.15.8.2-1-alpine

Openresty配置

docker run -v $PWD/conf/nginx.conf:/usr/local/openresty/nginx/conf/nginx.conf openresty/openresty:1.15.8.2-1-alpine

您应该挂载确切的文件，否则它将破坏容器。

这是/usr/local/openresty/nginx/conf/nginx.conf的默认配置

# nginx.conf  --  docker-openresty
#
# This file is installed to:
#   `/usr/local/openresty/nginx/conf/nginx.conf`
# and is the file loaded by nginx at startup,
# unless the user specifies otherwise.
#
# It tracks the upstream OpenResty's `nginx.conf`, but removes the `server`
# section and adds this directive:
#     `include /etc/nginx/conf.d/*.conf;`
#
# The `docker-openresty` file `nginx.vh.default.conf` is copied to
# `/etc/nginx/conf.d/default.conf`.  It contains the `server section
# of the upstream `nginx.conf`.
#
# See https://github.com/openresty/docker-openresty/blob/master/README.md#nginx-config-files
