'I don't want to ignore a file with no extension

I have a credentials file with no extension.

I would like to add this file to the docker to be available in the app directory.

Right now I have a file added in the root of the application but after building the image the file is missing

My dockerignore

**/.classpath
**/.dockerignore
**/.env
**/.git
**/.gitignore
**/.project
**/.settings
**/.toolstarget
**/.vs
**/.vscode
**/*.*proj.user
**/*.dbmdl
**/*.jfm
**/azds.yaml
**/bin
**/charts
**/docker-compose*
**/Dockerfile*
**/node_modules
**/npm-debug.log
**/obj
**/secrets.dev.yaml
**/values.dev.yaml

Try +([^.])

https://unix.stackexchange.com/a/87649

The bash extended glob +([^.]) will match files without any . in their name. It requires that you have not unset shopt extglob (on modern bash installations, it should be set by default). The pattern means:

any number (but at least one) of characters other than .
