Recent upgrade removes apt-get

[ifmason2]

We have been building an image based on mysql:5.7, where we pull in git, python 3.9 and the AWS commandline.
Since the update of 05/07/2022 (docker-library/official-images#12743), when we launch our docker file we get

Status: Downloaded newer image for mysql:5.7 ---> 34e82e623818 Step 2/14 : RUN apt-get update && apt-get upgrade -y && apt-get install -y python-pip python-dev build-essential git ---> Running in b21557a71b92 /bin/sh: apt-get: command not found

Creating a local docker based on mysql:5.7 we find that apt-get does not exist in /usr/bin or /usr/local/bin

@ifmason2 If it is urgent you can try using mysql:5.7-debian, which should always support apt-get.

Looking at this PR (line 19 and 25), it seems like they intentionally move the tag of 5.7 from debian to oracle.

[magnusbarata]

It seems they already decided to move to "oracle" variants by default. (see here)
So it is either you adapt to use yum as a package manager, or use "debian" variants image explicitly.

Quoting from the link above, the rationale for this decision were:

Update "oracle" variants to be the default variants

To reiterate the rationale:

more "upstream-supported" configuration
more architectures (hello, arm64v8!)
smaller images 👀

I will try with the debian variant. If that works, I will close the ticket.
Thanks @magnusbarata.

@magnusbarata,
That worked well, so I am happy to close the ticket.
Thanks for the quick response.
