寫在前面
看完Dokcer相關(guān)的書籍，正好有個(gè)項(xiàng)目要這樣搞，所以自己練習(xí)一下。
當(dāng)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(wú)論如何,我要為自己負(fù)起責(zé)任。——王小波《三十而立》
結(jié)構(gòu)圖：
這里僅作為一種學(xué)習(xí)，一般這種負(fù)載的話，Nginx是放到主機(jī)側(cè)的， JavaWeb(Tomcat)應(yīng)用放到容器里。
效果
新建文件夾。
D=uag;mkdir $D;cd $D;mkdir uag_nginx uag_tomcat8;
ls
uag_nginx uag_tomcat8
一，Ngixn 鏡像制作
cd uag_nginx/
# 用于存放配置文件
mkdir nginx
vim Dockerfile
Dockerfile 文件內(nèi)容
FROM nginx
LABEL maintainer="uag"
ENV REFRESHED_AT 2021-08-27
EXPOSE 8099
構(gòu)建nginx配置文件內(nèi)容
這個(gè)的配置文件，在容器運(yùn)行的時(shí)候通過(guò) -v參數(shù)與 容器內(nèi)部共享。方便后期參數(shù)更改
cd ./nginx
vim nginx.conf
nginx.conf 配置文件內(nèi)容
user nginx;
worker_processes auto;
error_log /var/log/nginx/error.log notice;
pid /var/run/nginx.pid;
daemon off;
events {
worker_connections 1024;
}
http {
include /etc/nginx/mime.types;
default_type application/octet-stream;
log_format main '$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(fù)載
upstream backend {
server 172.23.231.190:8069;
server 172.23.231.190:8079;
server 172.23.231.190:8089;
}
}
配置負(fù)載:172.23.231.190為宿主機(jī)IP,8069,8079,8089為對(duì)應(yīng)的Java Web 暴露的應(yīng)用端口。
# 這里配置負(fù)載
upstream backend {
server 172.23.231.190:8069;
server 172.23.231.190:8079;
server 172.23.231.190:8089;
}
構(gòu)建Nginx鏡像
docker build -t uag/uag_nginx .
二，java Web(Tomcat)應(yīng)用鏡像構(gòu)建
cd uag_tomcat8/
vim Dockerfile
Dockerfile 文件內(nèi)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(duì)應(yīng)的War包
構(gòu)建鏡像
docker build -t uag/uag_tomcat .
三，運(yùn)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

查看負(fù)載方式:–volumes-from 方式
