寫在前面
看完Dokcer相關的書籍，正好有個項目要這樣搞，所以自己練習一下。
當作一百世一樣。這里的道理很明白:我思故我在,既然我存在,就不能裝作不存在。無論如何,我要為自己負起責任。——王小波《三十而立》
結構圖：
這里僅作為一種學習，一般這種負載的話，Nginx是放到主機側的， JavaWeb(Tomcat)應用放到容器里。
效果
新建文件夾。
D=uag;mkdir $D;cd $D;mkdir uag_nginx uag_tomcat8;
ls
uag_nginx uag_tomcat8
一，Ngixn 鏡像制作
cd uag_nginx/
# 用于存放配置文件
mkdir nginx
vim Dockerfile
Dockerfile 文件內容
FROM nginx
LABEL maintainer="uag"
ENV REFRESHED_AT 2021-08-27
EXPOSE 8099
構建nginx配置文件內容
這個的配置文件，在容器運行的時候通過 -v參數與 容器內部共享。方便后期參數更改
cd ./nginx
vim nginx.conf
nginx.conf 配置文件內容
user nginx;
worker_processes auto;
error_log /var/log/nginx/error.log notice;
pid /var/run/nginx.pid;
daemon off;
events {
worker_connections 1024;
}
http {
include /etc/nginx/mime.types;
default_type application/octet-stream;
log_format main '$upstream_addr - $remote_addr - $remote_user [$time_local] "$request" '
'$status $body_bytes_sent "$http_referer" '
'"$http_user_agent" "$http_x_forwarded_for"';
access_log /var/log/nginx/access.log main;
sendfile on;
#tcp_nopush on;
keepalive_timeout 65;
#gzip on;
include /etc/nginx/conf.d/*.conf;
server {
listen 8099;
server_name localhost;
root /var/www/html/;
index index.html index.htm;
access_log /var/log/nginx/default_access.log main;
error_log /var/log/nginx/default_error.log;
location / {
proxy_pass http://backend;
}
location ~ .* {
proxy_pass http://backend;
proxy_set_header Host $http_host;
proxy_set_header X-Real-IP $remote_addr;
proxy_set_header X-Forwarded-For $proxy_add_x_forwarded_for;
}
}
# 這里配置負載
upstream backend {
server 172.23.231.190:8069;
server 172.23.231.190:8079;
server 172.23.231.190:8089;
}
}
配置負載:172.23.231.190為宿主機IP,8069,8079,8089為對應的Java Web 暴露的應用端口。
# 這里配置負載
upstream backend {
server 172.23.231.190:8069;
server 172.23.231.190:8079;
server 172.23.231.190:8089;
}
構建Nginx鏡像
docker build -t uag/uag_nginx .
二，java Web(Tomcat)應用鏡像構建
cd uag_tomcat8/
vim Dockerfile
Dockerfile 文件內容
FROM dordoka/tomcat
MAINTAINER LIRUILONG
COPY UAWeb.war /opt/tomcat/webapps/UAWeb.war
EXPOSE 8080
ENTRYPOINT [ "/opt/tomcat/bin/catalina.sh", "run" ]
上傳對應的War包
構建鏡像
docker build -t uag/uag_tomcat .
三，運行容器 Nginx鏡像
docker run -d -p 8099:8099 --name uag_nginx -v $PWD/nginx/nginx.conf:/etc/nginx/nginx.conf uag/uag_nginx nginx
java Web(Tomcat)鏡像
docker run -it -d -p 8089:8080 --name uag_app_1 uag/uag_tomcat
docker run -it -d -p 8079:8080 --name uag_app_2 uag/uag_tomcat
docker run -it -d -p 8069:8080 --name uag_app_3 uag/uag_tomcat

構建好鏡像上傳倉庫：
嗯，需要注冊一個Docker Hub賬號，然后登錄，需要鏡像前面加 賬戶名/
