10.1.0.1 Release - Container is unhealthy when running docker-compose up

[eriktbe]

I'm trying to setup a Sitecore XP 10.1.2 single instance development machine, but I'm encountering an issue with the 10.1.0.1 release/tag of the docker-examples solution.

Steps to reproduce:

1. Download the 10.1.0.1 release or clone the 10.1.0.1 tag
2. In the custom-images folder, run init.ps1
3. Next, run docker-compose up -d

Expected result:
The containers get build and start successfully.

Actual result:
The docker-compose up command exits with the following errors:

Creating network "docker-examples_default" with the default driver
Creating docker-examples_mssql_1 ... done
Creating docker-examples_solr_1 ... done
Creating docker-examples_solr-init_1 ... done
Creating docker-examples_xconnect_1 ... done
Creating docker-examples_id_1 ... done

Additional information:
Container "f08699d12809" is the xconnect container. When checking the logs for that container, the following errors are displayed in the logs:

When checking the docker\data\solr folder, there are no solr indexes present.

@eriktbe It might be related to a weak SQL admin password that is set in ".init.ps1" script. https://doc.sitecore.com/xp/en/developers/102/developer-tools/troubleshooting-docker.html#errors-due-to-an-invalid-sql-server-admin-password_body
