Which version of Alpine is this with, what is the SHA256 image digest of the image?

I played with Alpine 3.17 — docker run -it --rm --pull=always alpine:3.17 sh -i — and it seems fine:

# cat /etc/os-release 
NAME="Alpine Linux"
ID=alpine
VERSION_ID=3.17.7
PRETTY_NAME="Alpine Linux v3.17"
HOME_URL="https://alpinelinux.org/"
BUG_REPORT_URL="https://gitlab.alpinelinux.org/alpine/aports/-/issues"

# apk add supervisor
OK: 74 MiB in 33 packages

# python3 --version
Python 3.10.14

# grep -F XML_SetReparseDeferralEnabled /usr/lib/python3.10/lib-dynload/pyexpat.cpython-310-x86_64-linux-gnu.so 
XML_SetReparseDeferralEnabled

# grep -F XML_SetReparseDeferralEnabled /usr/lib/libexpat.so.1.9.2
XML_SetReparseDeferralEnabled

# python3 -c 'from pyexpat import *' && echo GOOD.
GOOD.

@hartwork

Thank you very much for being included!

I use alpine:3, 3.16, 3.16.3, latest

Install the supervisor: apk add supervisor

@unlike777 even with Alpine 3.16 things seem to work fine over here:

# docker run -it --rm --pull=always alpine:3.16 sh -c 'apk add -q supervisor ; python3 -c "from pyexpat import *" && echo GOOD.'
3.16: Pulling from library/alpine
Digest: sha256:452e7292acee0ee16c332324d7de05fa2c99f9994ecc9f0779c602916a672ae4
Status: Image is up to date for alpine:3.16
GOOD.

[unlike777]

The solution is to rebuild Alpine image

Closing since the above comments indicate this is not a bug in Supervisor.
