컨테이너 fedora-toolbox-32의 DEBU 진입점은 도구 상자(PID=0)입니다.
오류: 컨테이너 fedora-toolbox-32의 잘못된 진입점 PID

컨테이너 시작에 실패한 것 같습니다.

네, 좋지 않습니다. 기본적으로 Toolbox 코드에서 가져온 일부 라이브러리는 cgo를 사용해야 하는 C 코드를 사용합니다. cgo 가 빌드 중에 사용되고 시스템에서 libc 라이브러리가 발견되면 바이너리는 libc 라이브러리에 동적으로 링크됩니다. 이것은 일반적으로 괜찮지만 Toolbox가 컨테이너의 진입점으로 사용되기 때문에 다른 버전의 libc(resp. glibc)가 이를 깨뜨릴 수 있습니다. 수정 제안(#531)이 있지만 @debarshiray와 더 논의해야 합니다.

예, @HarryMichal이 언급했듯이 이것이 문제가 되는 부분입니다.

[vagrant@ci-node-33 ~]$ podman start --attach fedora-toolbox-32
toolbox: /lib64/libc.so.6: version `GLIBC_2.32' not found (required by toolbox)

이는 호스트의 Fedora 33의 glibc-2.32 에 대해 링크된 /usr/bin/toolbox 바이너리가 컨테이너 내부의 이전 Fedora 릴리스의 이전 glibc 에서 작동하지 않음을 의미합니다.

컨테이너의 진입점으로 사용할 수 있도록 호스트에서 컨테이너로 마운트 /usr/bin/toolbox 를 바인딩하기 때문에 이러한 상황이 발생합니다. 이것은 Toolbox가 POSIX 셸에서 구현되었을 때 과거에 잘 작동했으며 환경의 /bin/sh . 그러나 ELF 바이너리일 때는 잘 작동하지 않습니다.

나는 Fedora 33 바이너리를 잡고 압축을 풀고 조금 찔렀다.

$ rpm2cpio ./toolbox-0.0.93-2.fc33.x86_64.rpm | cpio -idmv
...
...
$ objdump -T ./usr/bin/toolbox | grep GLIBC_2.32
0000000000000000      DO *UND*  0000000000000000  GLIBC_2.32  pthread_sigmask

glibc-2.32 에 pthread_sigmask 의 새로운 구현이 있는 것 같습니다.

glibc-2.32 에서 pthread_sigmask 기호의 새 버전을 피하도록 Go 도구 모음에 지시하는 방법을 찾았습니다. 참조: https://github.com/containers/toolbox/pull/534
