Use 'bullseye' Debian version instead of unspecified one

[Van0SS]

This change is solving #262

Debian 12 "Bookworm" was released in early June, which was picked up by python docker image and as a result it broke Azure client.

This change would specify precise version of Debian, which is a good practice anyway. After the issue is solved version could be upgraded to 12.

Running in the container:
Before:

# cat /etc/os-release
PRETTY_NAME="Debian GNU/Linux 12 (bookworm)"
NAME="Debian GNU/Linux"
VERSION_ID="12"
VERSION="12 (bookworm)"
VERSION_CODENAME=bookworm
ID=debian
HOME_URL="https://www.debian.org/"
SUPPORT_URL="https://www.debian.org/support"
BUG_REPORT_URL="https://bugs.debian.org/"

# openssl version
OpenSSL 3.0.9 30 May 2023 (Library: OpenSSL 3.0.9 30 May 2023)

After:

# cat /etc/os-release
PRETTY_NAME="Debian GNU/Linux 11 (bullseye)"
NAME="Debian GNU/Linux"
VERSION_ID="11"
VERSION="11 (bullseye)"
VERSION_CODENAME=bullseye
ID=debian
HOME_URL="https://www.debian.org/"
SUPPORT_URL="https://www.debian.org/support"
BUG_REPORT_URL="https://bugs.debian.org/"

# openssl version

The azure SDK setup guide lists a bunch of dependencies to install on Debian. Do you need to add any of those to the Dockerfile too?

[Van0SS]

It works with current Dockerfile after the change, so I think it should be fine, good catch though

[ajar98]

agreed - particularly this is necessary because the azure SDK does not support openssl 3.0
