Windows環境搞好的Dockerfile文件 在Linux上報錯了

錯誤1：
standard_init_linux.go:187: exec user process caused "no such file or directory"

[root@izbp1dcscvry6tnoiqx8stz manager]# docker run --name managerV1 newhub.zkh360.com/zkh360/otter-manager-uat:v0.1
standard_init_linux.go:187: exec user process caused "no such file or directory"
[root@izbp1dcscvry6tnoiqx8stz manager]#
[root@izbp1dcscvry6tnoiqx8stz manager]# docker logs managerV1
standard_init_linux.go:187: exec user process caused "no such file or directory"
[root@izbp1dcscvry6tnoiqx8stz manager]#

原因： 鏡像的entrypoint設置的啟動腳本格式是dos，在linux系統上用vi修改成unix格式即可 【windows下操作之傷】
把.sh文件逐個執行以下操作：

1）用vi打開文件
2）執行 :set ff 然后回車，可以看到fileformat=dos

3)修改成unix
:set ff=unix 回車
4）執行:set ff，可以看到已經改為 fileformat=unix

錯誤2：

[root@izbp1dcscvry6tnoiqx8stz manager]# docker run 793059909/otter-manager-uat:v0.2 -it bash
DOCKER_DEPLOY_TYPE=VM
==> INIT /alidata/init/02init-sshd.sh
==> EXIT CODE: 0

[root@izbp1dcscvry6tnoiqx8stz manager]#

 

看了下main.sh的第27行是：

 

 

#!/bin/bash

[ -n "${DOCKER_DEPLOY_TYPE}" ] || DOCKER_DEPLOY_TYPE="VM"
echo "DOCKER_DEPLOY_TYPE=${DOCKER_DEPLOY_TYPE}"

# run init scripts
for e in $(ls /alidata/init/*) ; do
    [ -x "${e}" ] || continue
    echo "==> INIT $e"
    $e
    echo "==> EXIT CODE: $?"
done

echo "==> INIT DEFAULT"
service sshd start
service crond start

#echo "check hostname -i: `hostname -i`"
#hti_num=`hostname -i|awk '{print NF}'`
#if [ $hti_num -gt 1 ];then
#    echo "hostname -i result error:`hostname -i`"
#    exit 120
#fi

echo "==> INIT DONE"
echo "==> RUN ${*}"
exec "${@}"

先解決Py報錯的事，相關也是文件格式的事。果然：

仔細檢查報錯內容，並不會發現任何語句錯誤或者路徑錯誤，注意^m，這是windows下的斷元字符。所以問題就是，在多個環境上進行編寫，可能會因為字符（win/unix換行符不一樣）、縮進（兩個編輯環境的縮進tab/space不一致）均易導致這種神不知鬼不覺的錯誤，很難找到。

解決方法見上面*.sh腳本的解決辦法
