Copy with wildcard fails

[yossicohn]

Actual behavior Does not COPY or fails Tested with KANIKO 1.22 still a bug both will fail: COPY ./* ./ or COPY ./*.json ./

Expected behavior Copy all Files as defined by the wildcard btw, COPY ./ ./ used to work once

To Reproduce Steps to reproduce the behavior:

1. Docker file with COPY ./* ./ or COPY ./*.json ./
2. content of files in the context

Additional Information This is painful bug

Thanks for filing the bug @yossicohn ; could you specify the version of kaniko you're using and which release is the workable one?

[yossicohn]

@JeromeJu the latest I know of working is v1.12.0, in the process of upgrade to the latest I got all the issues of the COPY I mentioned above

Hi @yossicohn could you provide whats is the error or the behavior in your case? is it file not found, is it error or something else?

[yossicohn]

@prima101112 Examples and most painful COPY . . I get no error, but it does not copy anything vs. the original behavior of copying all the context files.

if I do COPY ./ssh/* ./ssh I get an error {"level":"info","msg":"Resolving srcs [.ssh/*]...","time":"2024-04-02T08:40:22Z"} error building image: error building stage: failed to get files used from context: copy failed: no source files specified

Same for other wildcards usages like *.json etc. btw, the following does work COPY ./ssh ./ssh

[prima101112]

tested master branch with

COPY ./* ./

its copy all files. but dunno with COPY ./ ./ is the docker behavior will copy all files?

@prima101112 as far as I can see the copied content via COPY ./* ./ is not really working, as it is not available. I tried it and the Folders are not available, cd into the folders fails

drwxrwxrwx    1 root     root            31 Apr 24 06:52 .
drwxr-xr-x    1 root     root            40 Apr 24 06:53 ..
lrwxrwxrwx    1 root     root            51 Apr 24 06:52 myfolder -> .worktrees/e15ba753ddeafecc38225a329b90f69a9ef70545
# cd myfolder
/bin/sh: cd: can't cd to myfolder: No such file or directory

Regarding COPY ./ ./ or COPY ./ssh/* ./ssh or COPY ./*.json ./ all these are not working as for v1.22 and are very needed behavior and feature

Can you recheck this?

[yossicohn]

@prima101112 hi, FYI I've just tested the version v1.23.0 and the issues describes still persist

[prima101112]

@yossicohn will check it

Hi @yossicohn just try and test using latest 1.23 and its work fine

I got similar error but related to --from. Issue seems that kaniko does not support fully qualified image names including registry. adding FROM as bla and then use COPY --from=bla enabled me to use wildcards.

Wildcard in copy still seems to fail, even in the latest version
