The credentials for all Payara Server docker images are admin/admin for the username and password. You can find this out in the README in the GitHub repositories (also available in Docker Hub):
https://github.com/payara/docker-payaraserver-full/blob/5.183/README.md
...the admin interface is secured by default (in both the default domain1 as well as payaradomain), accessible using HTTPS on the host machine: https://localhost:4848 The default user and password is admin.
You can also see this is the case from the actual Dockerfile at line 34:
https://github.com/payara/docker-payaraserver-full/blob/5.183/Dockerfile#L34
ENV ADMIN_PASSWORD admin
If this isn't working for you, then something else is probably going on.
I tested this myself using docker run -it -p 4848:4848 payara/server-full:5.183
and found I could log in with admin/admin. For reference, here is the exact image I was using:
REPOSITORY TAG IMAGE ID CREATED SIZE
payara/server-full 5.183 b216dd970898 3 months ago 973MB
Check that your ID matches to verify that it is the same image.
