libdl.so.2 error in postgres container #758

Closed spencergilbert closed 4 years ago

spencergilbert commented 4 years ago

/bin/sh: error while loading shared libraries: libdl.so.2: cannot open shared object file: No such file or directory

Images in use:

Running in kubernetes 1.16.2 - rancher on bare metal Ubuntu 18.04.3 LTS machines. Any ideas on what the issue or fix might be? Not sure if this issue should be here or in the spilo/patroni repos.

Thanks!

The image works perfectly:

$ docker run --rm -ti registry.opensource.zalan.do/acid/spilo-11:1.6-p1

exciting! I got onto one of our physical nodes and did that...

so i'm assuming something about how are machines are setup/or security hardened has messed with that lib I guess...

Figured this out! We're running Aqua for security and removing that resolves the issue. Thanks!

I faced a similar issue. For those who cant stop aqua agents. you can update aqua enforcers configmap - with AQUA_PRELOAD_NO_LIBDL: "true"
