Docker：来自守护程序的响应错误：rpc error：code = 2 desc =“oci运行时错误：exec格式错误”

问题描述

我写了以下docker文件

I wrote the following docker file

FROM cloudera/quickstart

MAINTAINER abhishek "http://www.foobar.com"

ADD ./SparkIntegrationTestsAssembly.jar /
ADD ./entrypoint.sh /
ADD ./twitter.avro /

EXPOSE 8020 50070 50010 50020 50075 8030 8031 8032 8033 8088 8040 8042 10020 19888 11000 8888 18080 7077

RUN chmod +x /entrypoint.sh
ENTRYPOINT ["/entrypoint.sh"]

我使用命令构建了我的图像

i built my image using the command

docker build --tag foobar:auto .

此命令的输出是

但是当我尝试运行我的容器使用

But when i try to run my container using

docker run --hostname=quickstart.cloudera --rm --privileged=true -t -i  -p "8020:8020" -p "50070:50070" -p "50010:50010" -p "50020:50020" -p "50075:50075" -p "8030:8030" -p "8031:8031" -p "8032:8032" -p "8033:8033" -p "8088:8088" -p "8040:8040" -p "8042:8042" -p "10020:10020" -p "19888:19888" -p "11000:11000" -p "8888:8888" -p "18080:18080" -p "7077:7077" foobar:auto

我收到错误

docker: Error response from daemon: rpc error: code = 2 desc = "oci runtime error: exec format error".

我的entrypoint.sh文件看起来像

My entrypoint.sh file looks like

/usr/bin/docker-quickstart
service hadoop-hdfs-namenode restart
hdfs dfs -mkdir -p input
hdfs dfs -put /twitter.avro /input/twitter.avro
spark-submit --class com.abhi.HelloWorld --master local[1] SparkIntegrationTestsAssembly.jar /input/twitter.avro /output

推荐答案

您是否发布了完整的 entrypoint.sh ？
内核尝试通过查看可执行文件的第一个字节来识别文件类型。对于脚本，您需要添加所谓的行。您可能需要在 entrypoint.sh 的顶部添加一条shebang行，例如：

Did you post your complete entrypoint.sh?The kernel tries to recognize the file type by looking at the first bytes of the executable. For scripts you need to add a so-called shebang line. You might need to add a shebang line at the very top of your entrypoint.sh, e.g.:

#!/bin/sh
/usr/bin/docker-quickstart
service hadoop-hdfs-namenode restart
hdfs dfs -mkdir -p input
hdfs dfs -put /twitter.avro /input/twitter.avro
spark-submit --class com.abhi.HelloWorld --master local[1] SparkIntegrationTestsAssembly.jar /input/twitter.avro /output
