Downstream work

• Support for the experimental Databricks CLI launcher databrickslabs/ucx#517
• Added Databricks CLI installer PoC databrickslabs/dlt-meta#19
• Added entrypoint for Databricks CLI databrickslabs/discoverx#84

Downstream command router can be really trivial:

importloggingimportsys, jsonfromdatabricks.sdkimportWorkspaceClientfromdatabricks.labs.ucx.installimportWorkspaceInstallerdefjobs():
ws=WorkspaceClient()
installer=WorkspaceInstaller(ws)
forstep, job_idininstaller.deployed_steps().items():
print(step, job_id)
defme():
ws=WorkspaceClient()
my_user=ws.current_user.me()
print(my_user.user_name)
MAPPING= {
'jobs': jobs,
'me': me,
}
defmain(raw):
payload=json.loads(raw)
command=payload['command']
ifcommandnotinMAPPING:
raiseKeyError(f'cannot find command: {command}')
flags=payload['flags']
log_level=flags.pop('log_level')
iflog_level!='disabled':
databricks_logger=logging.getLogger("databricks")
databricks_logger.setLevel(log_level.upper())
kwargs= {k.replace('-', '_'): vfork,vinflags.items()}
MAPPING[command](**kwargs)
if__name__=="__main__":
main(*sys.argv[1:])

#914 (comment) - fixed

these two are related to dev mode, that we'll fix by talking with dev - #914 (comment)#914 (comment)

This change LGTM and acknowledge there will be follop-ups on the UX.

Would appreciate a second pair of eyes before a stamp.

[pietern]

These won't be cleared in the environment because they are zero. That means they are not returned from e.environmentFromConfig below and are not cleared for the subprocess, which could confuse downstream programs.

[nfx]

@pietern the only case possible when we have --profile (DATABRICKS_CONFIG_PROFILE) is the local dev machine. Github actions (and likes) won't have the DATABRICKS_CONFIG_PROFILE / DATABRICKS_CONFIG_FILE envs set, but rather direct ones, like client ids or hosts. there are tests that verify this to work from github actions-like environments

@pietern and I reviewed this together this afternoon and feel generally good about it. Let's get labs on the road!

[pietern]

Removed from the merge queue if you want to take a look at the issue above.

[nfx]

@pietern that permutation of configuration flags is very unlikely to happen and has unit tests already. going ahead with the merge :)
