1.制作2個jar-srpingboot demo包
這里我分享現(xiàn)成的jar包
2. 編寫Dockerfile
FROM java:alpine
RUN mkdir -p /app
WORKDIR /app
EXPOSE 8080
ENV LANG en_US.UTF-8
#RUN apk add --update --no-cache ttf-dejavu fontconfig && rm -rf /var/cache/apk/*
ADD demo.jar ./demo.jar
ENTRYPOINT ["java","-Djava.security.egd=file:/dev/./urandom","-jar","/app/demo.jar"]
3.構(gòu)建鏡像
docker build -t demo:v1.0 .
4.運行容器
docker container run -dit -p:8080 -m 1G -e "SPRING_PROFILES_ACTIVE=test" -e "SERVICE_IP=內(nèi)/外網(wǎng)IP" -e "SERVICE_CHECK_HTTP=/actuator/health/" --name demo demo:v1.0 /bin/bash
5.檢測consul注冊服務(wù)情況

6.瀏覽器輸入域名
輪詢獲取2個jar輸出內(nèi)容

再刷新就只獲取jar包2 因為jar包1停了 掂恕，那么在jar包1停的時候程序自動更換獲取到j(luò)ar包2的過程并沒有發(fā)生客戶端異常就說明滾動無感更新成功

nginx配置如下：
upstream demoapi {
server 127.0.0.1:2365;
upsync 127.0.0.1:8500/v1/catalog/service/demo upsync_timeout=20m upsync_interval=500ms upsync_type=consul_services strong_dependency=off;
upsync_dump_path /etc/nginx/servers/www.demo.com.conf;
check interval=3000 rise=2 fall=5 timeout=10000;
keepalive 20000;
}
server {
listen 80;
server_name demo.xxx.com;
large_client_header_buffers 4 128k;
location / {
client_body_buffer_size 1024k;
client_max_body_size 0;
proxy_connect_timeout 300s;

proxy_buffer_size 64k;
proxy_buffers 4 32k;
proxy_busy_buffers_size 64k;
proxy_redirect off;
proxy_hide_header Vary;
proxy_set_header Accept-Encoding '';
proxy_set_header Host $host;
proxy_set_header Referer $http_referer;
proxy_set_header Cookie $http_cookie;
proxy_set_header X-Real-IP $remote_addr;
proxy_set_header X-Forwarded-For $proxy_add_x_forwarded_for;
proxy_buffering off;
proxy_headers_hash_max_size 51200;
proxy_headers_hash_bucket_size 6400;
proxy_temp_file_write_size 64k;
proxy_http_version 1.1;
proxy_set_header Connection "";
proxy_pass http://demoapi/;
}
}
jenkins pipeline流水線版本化發(fā)布更新 ----后續(xù)可以把打好的包傳到指定多臺服務(wù)器上然后依次主機上去docker run容器 更新發(fā)布從而實現(xiàn)無感發(fā)布更新 -可以通過ansible 或者 shell腳本 或者pipeline自帶
