hj_服務器操作記錄03_jdk11安裝,podman運行springboot--jar包程序
主機環境安裝jdk11;
官網下載: https://www.oracle.com/java/technologies/downloads/#java11
本機是centos8 64位系統的.選擇的是x64 Compressed Archive jdk-11.0.13_linux-x64_bin.tar.gz ;
上傳此安裝包到 /home下解壓暫放. tar zxf jdk-11.0.13_linux-x64_bin.tar.gz 得到 jdk-11.0.13 文件目錄;
拷貝此目錄到 usr/local/jdk 下. mkdir /usr/local/jdk ; cp -r /home/jdk-11.0.13 /usr/local/jdk ;
設置環境變量,配置 /etc/profile 文件, 文件尾部添加:
# JAVA11_HOME
export JAVA11_HOME=/usr/local/jdk/jdk-11.0.13 export CLASSPATH=$JAVA11_HOME/lib export PATH=$JAVA11_HOME/bin:$PATH
刷新此配置文件: source /etc/profile ;
檢查是否安裝成功: java javac java -version
宿主機安裝jdk11 over.
創建Dockerfile 上傳springboot-jar包,運行...
[root@iZc3hwg7f2i7mfZ jdk]# cd /home/ [root@iZc3hwg7f2i7mfZ home]# mkdir hj_docker_01 [root@iZc3hwg7f2i7mfZ home]# cd hj_docker_01/ [root@iZc3hwg7f2i7mfZ hj_docker_01]# touch Dockerfile [root@iZc3hwg7f2i7mfZ hj_docker_01]# ls Dockerfile hj1208-0.0.1-SNAPSHOT.jar
不使用宿主機jdk,拉取openjdk11的鏡像掛載jar包..直接run

配置 Dockerfile運行..還是得使用那個openjdk11...宿主機的jdk白裝啦,不會用
# 基礎鏡像使用java FROM docker.io/library/openjdk:11 # 作者 MAINTAINER hj # VOLUME 容器掛載目錄/tmp。 VOLUME /opt/hj/tmp # 將jar包添加到容器中并更名為hj1209.jar ADD hj1208-0.0.1-SNAPSHOT.jar hj1209.jar # 時區 RUN echo "Asia/Shanghai" > /etc/localtime_bak # 暴露端口 EXPOSE 8888 # 包前面的add命令把jar復制添加,這個touch命令的作用是修改這個文件的(訪問,修改時間)為當前時間,可有可無 RUN bash -c 'touch /hj1209.jar' # 運行jar ENTRYPOINT ["java","-jar","/hj1209.jar"]

怎么使用宿主機的jdk 有待進一步研究...
