通过Dockerfile创建项目部署镜像超时

首先将j项目jar包和Dockerfile文件:放于目录
/var/lib/docker/tmp
我的Dockerfile文件:
FROM java:8
EXPOSE 8080
VOLUME /tmp
ENV TZ=Asia/Shanghai
RUN ln- sf /usr/share/zoneinfo/{TZ} /etc/locatime && echo “{TZ}” > /etc/timezone
ADD myshop.war /app.jar
RUN bash -c ‘touch /app.jar’
ENTRYPOINT “java”,"-jar",“app.jar”
运行命令
docker build -t myshop .
运行结果
Sending build context to Docker daemon 3.072kB
Step 1/8 : FROM java:8
Get https://registry-1.docker.io/v2/library/java/manifests/8: Get https://auth.docker.io/token?scope=repository%3Alibrary%2Fjava%3Apull&service=registry.docker.io: net/http: TLS handshake timeout
错误分析:步骤1即出错，文件在基础镜像 java:8，查看是否镜像不存在或镜像名出错

更正或下载基础镜像后重新创建镜像(FROM jdk8)
创建成功
