docker内部的Spring Shell应用

Question

我正在尝试在docker容器内部署/运行spring shell应用程序。它正在启动，但是在尝试打开CLI时正在归档。

这可能是因为它无法对docker内部的任何终端进行罚款。我们该如何克服呢？

docker文件

FROM frolvlad/alpine-oraclejdk8:slim
VOLUME /tmp
ADD simulator-0.0.1-SNAPSHOT.jar app.jar
RUN sh -c 'touch /app.jar'
ENV JAVA_OPTS=""
EXPOSE 5432
ENTRYPOINT [ "sh", "-c", "java $JAVA_OPTS -Djava.security.egd=file:/dev/./urandom -Dspring.profiles.active=uat -jar /app.jar" ]

Answer 1

我使用-t选项运行容器以跳过该错误。 如果您想与容器-it

进行交互

编译图像

$ docker build -f Dockerfile -t my-spring-shell-image .

查看图片注册表

$ docker images

运行图像！

$ docker run -t -p 5432: 5432 my-spring-shell-image

如果要访问终端，则必须输入

$ docker run -it -p 5432: 5432 my-spring-shell-image
