Bash 错误："；“用户”；指令只有在主进程以超级用户权限运行时才有意义

嗨，当我尝试在dockerfile中实现一个新用户而不是使用根用户时，我遇到了以下错误

2020-10-16T09:28:04.554363522Z nginx: [warn] the "user" directive makes sense only if the master process runs with super-user privileges, ignored in /etc/nginx/nginx.conf:5
2020-10-16T09:28:04.564383012Z nginx: [emerg] mkdir() "/var/lib/nginx/tmp/client_body" failed (13: Permission denied)

2020-10-16T09:28:06.891084727Z nginx: [emerg] mkdir() "/var/lib/nginx/tmp/client_body" failed (13: Permission denied)
2020-10-16T09:28:09.331807870Z nginx: [warn] the "user" directive makes sense only if the master process runs with super-user privileges, ignored in /etc/nginx/nginx.conf:5
2020-10-16T09:28:09.342560643Z nginx: [emerg] mkdir() "/var/lib/nginx/tmp/client_body" failed (13: Permission denied)

下面是我创建的以下dockerfile。我已经创建了一个新的api网关，但是，当我构建docker映像并运行容器时，会出现上述错误

对于我需要实现哪些更改才能让用户而不是根用户工作，有什么建议吗

USER root
RUN microdnf --setopt=tsflags=nodocs install -y nginx procps shadow-utils net-tools ca-certificates dirmngr gnupg wget vim\
            && microdnf clean all \
            && rpm -q procps-ng

ENV NGINX_USER="api-gatway" \
    NGINXR_UID="8987" \
    NGINX_GROUP="api-gatway" \
    NGINX_GID="8987"     

RUN set -ex; \
  groupadd -r --gid "$NGINX_GID" "$NGINX_GROUP"; \
  useradd -r --uid "$NGINXR_UID" --gid "$NGINX_GID" "$NGINX_USER" 

#To start up NGINX 
EXPOSE 80
RUN mkdir -p /var/lib/nginx/
RUN mkdir -p /var/log/nginx/

RUN mkdir -p /var/lib/nginx/tmp/

RUN chown api-gatway /var/lib/nginx/
RUN chownd api-gatway /var/log/nginx/
USER api-gatway
CMD ["nginx", "-g", "daemon off;"]

由于您在Dockerfile中指定了备用

用户

，因此nginx无法在启动时切换用户。您可以在Dockerfile或nginx配置中指定一个用户，但这两者都没有意义。嗯，我已经在Kubernates集群上运行了docker映像，用户错误似乎消失了。但是权限被拒绝的错误仍然存在nginx:[emerg]mkdir（）“/var/lib/nginx/tmp/client_body”失败（13：权限被拒绝）您是否修复了此问题？
