@flow()
def obtain_kerberos_ticket(kerberos_block: KerberosCredentials) -> None:
logger = get_run_logger()
shell_run_command(
command='echo "${PASSWORD}" | kinit USERNAME; klist',
env={
'USERNAME': kerberos_block.username,
'PASSWORD': kerberos_block.password,
},
return_all=True)

10/28/2022, 9:18 PMHey Luca I think after you load the block you also need to call .get() to return the value for the secret str.
Something Like this assuming your loading the block earlier
Copy code
@flow()
def obtain_kerberos_ticket(kerberos_block: KerberosCredentials) -> None:
logger = get_run_logger()
shell_run_command(
command='echo "${PASSWORD}" | kinit USERNAME; klist',
env={
'USERNAME': kerberos_block.get("username"),
'PASSWORD': kerberos_block.get("password"),
},
return_all=True)

10/28/2022, 10:12 PM@Mason Menges it doesnt seem to be this.
Copy code
'USERNAME': kerberos_block.get('username'),
AttributeError: 'KerberosCredentials' object has no attribute 'get'Luca Schneider
10/28/2022, 10:13 PMThis is how I defined the block:
Copy code
from pydantic import SecretStr
from prefect.blocks.core import Block
class KerberosCredentials(Block):
username: str
password: SecretStr4 Views
