docker - 退出代码127和 ': No such file or directory`

Question

下面的容器``正在退出，代码为127，消息为': No such file or directory。

What specific changes need to be made in order for this error to resolve so that the container can run successfully?

docker 检查

以下是 docker ps -a -q的结果，然后是 docker inspect 1d86d855a3d1

C:\projects\docker\crowd\atlassian-crowd-docker>docker ps -a -q
1d86d855a3d1

C:\projects\docker\crowd\atlassian-crowd-docker>docker inspect 1d86d855a3d1

CharlesDuffy的建议

进行@CharlesDuffy的建议更改以将打印错误打印到stderr的结果如下:

C:\projects\docker\crowd\atlassian-crowd-docker>docker run -p 8443:8443 mycrowd  
+ PS4=':$BASH_SOURCE:$LINENO+'  
:/opt/start.sh:2+set -x  
:/opt/start.sh:2+$':\r'  
/opt/start.sh: line 2: $':\r': command not found  
:/opt/start.sh:3+set -euo $'pipefail\r'  
: invalid option name: set: pipefail  

然后，下一次迭代导致:

C:\projects\docker\crowd\atlassian-crowd-docker>docker run -p 8443:8443 mycrowd
+ PS4=':$BASH_SOURCE:$LINENO+'
:/opt/start.sh:2+set -x
:/opt/start.sh:2+:
:/opt/start.sh:3+set -euo pipefail
:/opt/start.sh:4+IFS='
    '
/opt/start.sh: line 6: DATABASE_CONFIG_OBJECT: unbound variable

Answer 1

start.sh显然包含DOS换行符。添加新命令:

RUN dos2unix /opt/start.sh

...在 COPY之后。
