我正在关注如何使用 Kubernetes 在 Google Cloud 上创建具有微服务的可扩展 API 的精彩教程。

我创建了 4 个微服务并公开了我正在使用 NGINX Plus 的服务。

注意: 这里 NGINX Plus / NGINX 的目的是作为反向代理。

下面是目录结构:

-nginx

--Dockerfile

--deployment.yaml

--index.html

--nginx-repo.crt

--nginx-repo.key

--nginx.conf

--svc.yaml

可以在此处查看文件的详细信息。我在这里粘贴 Docker 文件和 nginx.conf:

Dockerfile(NGINX Plus 原创):

FROM debian:8.3

RUN apt-get update && apt-get -y install wget

RUN mkdir -p /etc/ssl/nginx && wget -P /etc/ssl/nginx https://cs.nginx.com/static/files/CA.crt

COPY nginx-repo.key /etc/ssl/nginx/nginx-repo.key
COPY nginx-repo.crt /etc/ssl/nginx/nginx-repo.crt

RUN wget http://nginx.org/keys/nginx_signing.key && apt-key add nginx_signing.key

RUN apt-get -y install apt-transport-https libcurl3-gnutls lsb-release
RUN printf "deb https://plus-pkgs.nginx.com/debian `lsb_release -cs` nginx-plus\n" | tee /etc/apt/sources.list.d/nginx-plus.list
RUN wget -P /etc/apt/apt.conf.d https://cs.nginx.com/static/files/90nginx

RUN apt-get update && apt-get -y install nginx-plus

RUN mkdir /data
COPY index.html /data/index.html

COPY nginx.conf /etc/nginx/conf.d/backend.conf
RUN rm /etc/nginx/conf.d/default.conf

CMD ["nginx", "-g", "daemon off;"]

nginx.conf(NGINX Plus 原创):

resolver 10.11.240.10 valid=5s;

upstream reverse-backend {
    zone reverse-backend 64k;
    server reverse.default.svc.cluster.local resolve;
}

upstream arrayify-backend {
    zone arrayify-backend 64k;
    server arrayify.default.svc.cluster.local resolve;
}

upstream lower-backend {
    zone lower-backend 64k;
    server lower.default.svc.cluster.local resolve;
}

upstream upper-backend {
    zone upper-backend 64k;
    server upper.default.svc.cluster.local resolve;
}

server {
    listen 80;

    root /data;

    location / {
        index  index.html index.htm;
    }

    status_zone backend-servers;

    location /reverse/ {
        proxy_pass http://reverse-backend/;
    }

    location /arrayify/ {
        proxy_pass http://arrayify-backend/;
    }

    location /lower/ {
        proxy_pass http://lower-backend/;
    }

    location /upper/ {
        proxy_pass http://upper-backend/;
    }

}

server {
    listen 8080;

    root /usr/share/nginx/html;

    location = /status.html { }

    location /status {
        status;
    }
}

NGINX Plus 似乎一切正常,我可以使用 url 访问所有 4 个微服务,例如。http://xyzw/service[1|2|3|4]/?str=testnginx,其中http://xyzw是我的外部 IP,NGINX 负责内部路由请求。现在我愿意在没有 NGINX Plus 的情况下只使用 NGINX 来做同样的工作。

以下是 NGINX 的更新文件:

Dockerfile(为 NGINX 更新):

    FROM debian:8.3
    RUN apt-get update && apt-get -y install wget
    RUN mkdir -p /etc/ssl/nginx && wget -P /etc/ssl/nginx https://cs.nginx.com/static/files/CA.crt
    #COPY nginx-repo.key /etc/ssl/nginx/nginx-repo.key
    #COPY nginx-repo.crt /etc/ssl/nginx/nginx-repo.crt
    #RUN wget http://nginx.org/keys/nginx_signing.key && apt-key add nginx_signing.key
    RUN apt-get -y install apt-transport-https libcurl3-gnutls lsb-release
    #RUN printf "deb https://plus-pkgs.nginx.com/debian `lsb_release -cs` nginx-plus\n" | tee /etc/apt/sources.list.d/nginx-plus.list
    RUN wget -P /etc/apt/apt.conf.d https://cs.nginx.com/static/files/90nginx
    RUN apt-get update && apt-get -y install nginx
    RUN mkdir /data
    COPY index.html /data/index.html
    COPY nginx.conf /etc/nginx/conf.d/backend.conf
    #RUN rm /etc/nginx/conf.d/default.conf
    CMD ["nginx", "-g", "daemon off;"]

nginx.conf(为 NGINX 更新):

resolver 10.3.240.10 valid=5s;

upstream reverse-backend {
    zone reverse-backend 64k;
    server reverse.default.svc.cluster.local;
}

upstream arrayify-backend {
    zone arrayify-backend 64k;
    server arrayify.default.svc.cluster.local;
}
upstream lower-backend {
    zone lower-backend 64k;
    server lower.default.svc.cluster.local;
}
upstream upper-backend {
    zone upper-backend 64k;
    server upper.default.svc.cluster.local;
}
server {
    listen 80;
    root /data;
    location / {
        index  index.html index.htm;
    }
#    status_zone backend-servers;
    location /reverse/ {
        proxy_pass http://reverse-backend/;
    }
    location /arrayify/ {
        proxy_pass http://arrayify-backend/;
    }
    location /lower/ {
        proxy_pass http://lower-backend/;
    }
    location /upper/ {
        proxy_pass http://upper-backend/;
    }
}
#server {
#    listen 8080;
#
#    root /usr/share/nginx/html;
#
#    location = /status.html { }
#
#    location /status {
#        status;
#    }
#}

基本上,我已经删除了解析和服务器语句,它们是 NGINX Plus 的功能并且能够创建 docker 映像,将其上传到谷歌容器并创建我的部署和服务,但得到404 not found

我在这里遗漏了什么还是这是 NGINX 的限制?

如果有人对在 Google Cloud 上使用 NGINX、Docker 和 Kubernetes 有任何建议或先前的经验,请提出建议。
