[HTCondor-users] Basic Docker Build

[James Lord <james.lord@xxxxxxxxxxxxxxxxxxx>]

I am attempting to connect an execute node to either a cm or mini node per here: https://github.com/htcondor/htcondor/blob/master/build/docker/services/README.md

execute node:
```
docker run --rm -d \
 --name=condor-ex \
 -v /opt/containers/mini-condor/ex_config:/etc/condor/condor_config.local \
 -v /opt/containers/mini-condor/condor_pool_password:/etc/condor/passwords.d/POOL \
 htcondor/execute
```

mini node:
```
docker run --rm -d \
 --name=condor-mc \
 -p 9618:9618 \
 -p 8080:8080 \
 -v /opt/containers/mini-condor/mini_config:/etc/condor/condor_config.local \
 -v /opt/containers/mini-condor/condor_pool_password:/etc/condor/passwords.d/POOL \
 htcondor/mini
```
When I spin up both instances and try to run `condor_status` I get the following error on the execute node:
```
# condor_status
Error: communication error
AUTHENTICATE:1003:Failed to authenticate with any method
AUTHENTICATE:1004:Failed to authenticate using IDTOKENS
AUTHENTICATE:1004:Failed to authenticate using FS
```

What is the bare min I need to get another execute node (outside of ` htcondor/mini` itself) to connect to mini?
