Error #1:
```
Error response from daemon: network with name local_testnet already exists
```
Fixed by stopping and removing local_testnet containers and removing
the network
Error #2:
```
docker: Error response from daemon: Conflict. The name "/test_container_basic" is already in use by container a7cd15d479a964675e7f259de4ed852e7dfef85b447514728f437cd0b980a709. You have to remove (or rename) that container to beable to reuse that name..
```
Fixed by adding `--rm` flag.
