podman 容器在运行 ENTRYPOINT 脚本时崩溃

Question

我想根据 这些说明为 podman (almalinux:8) 容器内的 rhel8 构建 haproxy。

从这样构建的镜像运行容器

FROM almalinux:8

COPY make_ha_proxy.sh /usr/local/bin
ENTRYPOINT ["make_ha_proxy.sh"]

构建 hopraxy 时会崩溃。

当我这样做时

podman run -tdi --rm --name test -v ./return:/tmp/binary_return almalinux:8
podman cp make_ha_proxy.sh test:/usr/local/bin
podman exec -it test2 bash /usr/local/bin/make_ha_proxy.sh

相反，我可以随后从

./return

目录收集我的二进制文件，因此我的脚本总体上似乎可以工作。

#!/usr/bin/bash

HAPROXY_MINOR='2.8.2'
HAPROXY_MAJOR='2.8'
LUA_VERSION='5.4.6'
RETURN_DIR='/tmp/binary_return/'

   mkdir -p -- "${RETURN_DIR}"
fi

# copying the created binary to the return directory
if [ $(file -b --mime-type /opt/haproxy/haproxy-${HAPROXY_MINOR}/haproxy | sed 's|/.*||') == application ] ; then
   cp /opt/haproxy/haproxy-${HAPROXY_MINOR}/haproxy "${RETURN_DIR}"/
else
   exit 1
fi

exit 0

任何提示，我的问题可能是什么？

似乎我的 Dockerfile 中的

ENTRYPOINT

需要整个路径，而不仅仅是脚本的名称

FROM almalinux:8

COPY make_ha_proxy.sh /usr/local/bin
ENTRYPOINT ["/usr/local/bin/make_ha_proxy.sh"]
