Igor Ostapenko commented on TINKERPOP-2685:
-------------------------------------------
I'm running Docker Desktop @ macOS Catalina with docker engine 19.03.5 inside.
According to the facts I have, this is not a Tinkerpop's bug. I think it's
somehow related to older Linux version + recent Alpine + recent bash.
{code:java}
bash-5.1$ uname -a
Linux 2fefbc3bd3c4 4.9.184-linuxkit #1 SMP Tue Jul 2 22:58:16 UTC 2019 x86_64
Linux {code}
Bash from official packages for Alpine 3.14 or 3.15 shows the same problem:
{code:java}
> docker run --rm -it alpine:3.14.3 sh
/ # apk add bash
fetch https://dl-cdn.alpinelinux.org/alpine/v3.14/main/x86_64/APKINDEX.tar.gz

1 {code}
But bash with Alpine 3.12 (what tinkerpop/gremlin-server:3.5.0 is based on)
works correctly:
{code:java}
> docker run --rm -it alpine:3.12.9 sh

Well, I should be told to upgrade the kernel (aka "upgrade Docker Desktop"),
but... this is the host what works with Docker without issues for ~3 years for
different projects and modern tech stacks. It's hard to state that kernel is
"not enough", such times passed when Docker was evolving actively and kernel
upgrades were required from time to time.
Okay, I guess you may close this issue and I will try to find Alpine/Bash guys
to discuss this, probably there is an official reason why it does not work with
4.x kernel. If I have updates I will post it here for completeness of the
history :).
P.S. Please excuse me if it took a lot of your time.
