The process of making nginx image is divided into three steps
1. Make dockerfile file
2. Make nginx installation script of nginx.sh
3. Make ngx-depolyment.yaml file
Here are the details
#mkdir /root/dockerfile #cd /root/dockerfile #touch Dockerfile #mkdir nginx //Making a dockerfile file root@<cc_172.16.0.2|~/dockerfile/nginx>:#cat Dockerfile #Centos based container with tengine2.2 FROM docker.io/centos MAINTAINER wbb-20181207 wbb@qq.com #prepare java environment ENV LD_LIBRARY_PATH /usr/local/luajit/lib:$LD_LIBRARY_PATH ENV LUAJIT_INC /usr/local/luajit/include/luajit-2.0 ENV LUAJIT_LIB /usr/local/luajit/lib #copy jdk tomcat to container ADD nginx.tar.gz /root/ RUN cd /root/nginx/ \ && sh ngxinstall.sh \ #The nginx.sh installation script is written in script separately, as shown below && ln -sf /dev/stdout /var/log/nginx/access.log \ #Let nginx log be displayed in k8s Web UI, as shown below && ln -sf /dev/stderr /var/log/nginx/error.log #private expose EXPOSE 80 #START NGINX #ENTRYPOINT [ "/usr/local/nginx/sbin/nginx", "-g", "daemon off;" ] CMD ["/usr/local/nginx/sbin/nginx", "-g", "daemon off;"] Be sure to run at the front desk,Otherwise k8s stay deploy Cannot create successfully in
cd /root/dockerfile docker build -t nginx:v4 .
Screenshot of installation process
The installation script of ngxinstall.sh is referenced in the dockerfile. It is better to test the following installation script on one machine first. If there is no problem, you can directly reference it in the dockerfile
Make nginx installation script of nginx.sh

The generated nginx pod displayed in k8s dashboard,
Internet access display test page
nginx logs are displayed in the Web UI. To display logs here, you must define them in the dockerfile. Otherwise, they will be displayed. Because the logs displayed in k8s are obtained from / dev/stdout /dev/stderr
