Develop Pipeline Debugging Notes

Comman errors we run into on our develop pipelibe

## Service broker url is taken
The error messgae is like this:

```Server error, status code: 400, error code: 270003, message: The service broker url is taken: url```

**Solutions**

The servive broker registered in the last run is not cleaned up. We do not have ensure broker deregistrar task in our pipleline. 
We can run the following commands to deregister service broker.

```
   bosh target develop_pipeline
   bosh download manifest <deployment_name> deployment_name.yml
   bosh deployment deployment_name.yml
   bosh run errand broker_deregistrar
 ```
If this failed to work, we can also target to rdpg-cf bosh-director, then set cf api, directy run 

`cf delete-service-broker rdpg-sb`.

## IP address is in use
The error message is like this

```
Failed creating bound missing vms > rdpg/2: Unknown CPI error 'Unknown' with message 'Address 10.10.1.12 is in use.' (00:10:26)
Failed creating bound missing vms > rdpg/3: Unknown CPI error 'Unknown' with message 'Address 10.10.1.21 is in use.' (00:10:26)
...
```
Solution
Check if any other deployments already used the Ips, delete the deployment which used the IPs we are going to use or change network setting to use different Ips.
