docker - Docker中的Subshel​​l命令

Question

在构建过程中，我需要调用zipalign，它位于我正在使用的docker容器中的某个路径上:

$ docker run nathansamson/flutter-builder-docker:v0.7.3 find . -iname zipalign
./opt/android-sdk-linux/build-tools/28.0.1/zipalign

如果docker容器已更新并且有新的android sdk，则此路径可以更改。例如，这可能是将来的道路:

$ docker run nathansamson/flutter-builder-docker:v0.9.9 find . -iname zipalign
./opt/android-sdk-linux/build-tools/42.0.0/zipalign

因此，与其硬编码对

docker run nathansamson/flutter-builder-docker:v0.7.3 \
/opt/android-sdk-linux/build-tools/28.0.1/zipalign -h 

我想要一个通用的解决方案，该解决方案可以自动找到zipalign的路径。我已经尝试过一个subshel​​l

$ docker run nathansamson/flutter-builder-docker:v0.7.3 $(find . -iname zipalign) -h
docker: Error response from daemon: OCI runtime create failed: 
container_linux.go:348: starting container process caused "exec: \"-h\": 
executable file not found in $PATH": unknown.
ERRO[0001] error waiting for container: context canceled 

并为该文件夹添加通配符:

$ docker run nathansamson/flutter-builder-docker:v0.7.3 /opt/android-sdk-linux/build-tools/*/zipalign -h 
docker: Error response from daemon: OCI runtime create failed: 
container_linux.go:348: starting container process caused "exec: 
\"/opt/android-sdk-linux/build-tools/*/zipalign\": stat /opt/android- 
sdk-linux/build-tools/*/zipalign: no such file or directory": unknown.
ERRO[0001] error waiting for container: context canceled 

因此，子shell和通配符在Docker中不起作用。有什么想法可以在我每次打电话时找到zipalign的路径吗？

find可以使用-exec选项执行某些操作。

find . -name zipalign -exec bash -c '"$0"' {} \;

在您的示例中:

docker run nathansamson/flutter-builder-docker:v0.7.3 find . -name zipalign -exec bash -c '"$0"' {} \;
