Docker base image for perl; E: Package 'libssl1.0.0' has no installation candidate

Question

I have a dockerfile that uses perl:5.22 as the base image When I do:

#Dockerfile:

From perl:5.22
RUN apt-get update && apt-get install libssl1.0.0 libssl-dev

I get this error: When I do: sudo apt-cache policy libssl1.0.0 in the dockerfile, like this:

#Dockerfile:

From perl:5.22
RUN apt-cache policy libssl1.0.0 && \
    apt-cache policy libssl-dev
RUN apt-get update && apt-get install libssl1.0.0

I get:

Step 2/3 : RUN apt-cache policy libssl1.0.0 && apt-cache policy libssl-dev ---> Running in a60f0185ef5a libssl1.0.0:
Installed: (none) Candidate: (none)
Version table: libssl-dev:

There's no available candidate to install libssl1.0.0; I get:

E: Package 'libssl1.0.0' has no installation candidate

However there's a candidate to install the libssl-dev package, but none for the libssl1.0.0

I'm new with docker; does the perl 5.22 base image already come with libssl1.0.0 already preinstalled in the image? I couldn't see it in their base image and secondly, *how do I install this package (libssl1.0.0) in my dockerfile if there's no candidate available to install it*?

Lastly, since the base image already comes preinstalled with the libssl-dev could I use this package, libssl-dev, instead of the libssl1.0.0, is there a difference between libssl-dev and libssl1.0.0 ?

Actually, it is already installed by default.

$ docker run -it perl:5.22 /bin/bash
root@e5315bc25223:~# apt search libssl

libssl-dev/now 1.1.0f-3+deb9u2 amd64 [installed,local]
  Secure Sockets Layer toolkit - development files

libssl1.0.0/now 1.0.1t-1+deb8u8 amd64 [installed,local]
  Secure Sockets Layer toolkit - shared libraries

~~The perl image is based on debian:stretch, which no longer supports libssl1.0.0. You can pull the package from jessie (https://packages.debian.org/jessie/libssl1.0.0) and install with dpkg.~~

Sample Dockerfile addition:

RUN wget "http://security.debian.org/debian-security/pool/updates/main/o/openssl/libssl1.0.0_1.0.1t-1+deb8u8_amd64.deb" \
    && dpkg -i libssl1.0.0_1.0.1t-1+deb8u8_amd64.deb

Regarding the version, apt show libssl-dev gives:

Package: libssl-dev

Version: 1.1.0f-3+deb9u2

As far as if you can use 1.1.0 instead of 1.0.0, that really depends on your software's requirements.
