Another question is in the previous version. I have used the variables 
PREFECT_URL_UI_API_URL
to set the config of the remote server and 
PREFECT_API_URL
from my local to set the IP address. After updating this version I try to set the same but got some errors with the same variables. And after reading the docs I found this. I am not sure how to set the other server apart from the Prefect Cloud and the Local.
Copy code
# use a local Orion API server
prefect config set PREFECT_API_URL=<http://127.0.0.1:4200/api>

# use Prefect Cloud
prefect config set PREFECT_API_URL=<http://app.prefect.cloud/api>

Hi Surawut, did you try specifying the block type with a capital S? Like S3: 
--storage-block S3/mlflow-artifacts-prem
s
Hi. I try it and got this new error:
Copy code
raise ValueError(
ValueError: Unable to find block document named mlflow-artifacts-prem for block type S3
t
In the UI is it showing an S3 block with the exact name 
mlflow-artifacts-prem
?
s
let me check the UI a bit.
Yeah. The UI already showing the S3 block.
t
Are you using cloud? Or did you run 
prefect orion start
?
s
just 
prefect orion start
but using S3 for storage.
t
hmm, I wonder if you may have logged into cloud in the terminal and now can not access this local block?
I would also try creating a new block in the UI and trying again.
I am not sure for now, but let me know if you find anything out!
Have you run 
prefect cloud login
at all?
s
No. I haven’t used Prefect cloud.
I want to try with my remote server first. but I don’t know how to set the config variable for 
PREFECT_ORION_URL_UI_URL
that one is the variable that I used before in Prefect 2.0b5 or 6.
the error I got after assigning to the old variable.
Copy code
(base) ubuntu@ip-172-31-26-134:~/course-mlops-zoomcamp/03-orchestration$ prefect config set PREFECT_ORION_URL_UI_URL="<http://54.193.87.108:4200/api>"
Unknown setting name 'PREFECT_ORION_URL_UI_URL'.
Trying to find the new one to set it.
t
Here is some documentation that you may find helpful. Regarding the S3 block as I said, it wouldn’t hurt to recreate the S3 block in the UI and try again with that. Overall just verify that your cli commands (flows you run, workqueues listed) match what you see in the UI. Regarding the config variable, My other colleagues may be around later who know more about this, but I would ask it as a separate question in the channel.
s
Yeah, I read from this one. found some commands that I think should be the ones that I looking for.
Copy code
# use a local Orion API server
prefect config set PREFECT_API_URL=<http://127.0.0.1:4200/api>

# use Prefect Cloud
prefect config set PREFECT_API_URL=<http://app.prefect.cloud/api>
Yeah, It works well. I can use Prefect with my remote server now. but it seems like the new one.
No block and no run.
I got connect error for now. after using my remote server and run the command to build deployment

Hi @Surawut Jirasaktavee - you should be able to see what settings options there are here: https://github.com/PrefectHQ/prefect/blob/ea6f062d5005096ff890aab9595cecc1e4bde9ed/src/prefect/settings.py
gratitude thank you 1

Hi, Jenny. Thank you. I will check this.
Now I can use my remote server to open the Prefect UI. but when I run the command to build the deployment. I get the connection error.

For now, I think I can use my local connect with Prefect remote server perfectly but I am stuck with the error about 
S3
:
Copy code
botocore.exceptions.ParamValidationError: Parameter validation failed:
Invalid bucket name "s3:": Bucket name must match the regex "^[a-zA-Z0-9.\-_]{1,255}$" or be an ARN matching the regex "^arn:(aws).*:(s3|s3-object-lambda):[a-z\-0-9]*:[0-9]{12}:accesspoint[/:][a-zA-Z0-9\-.]{1,63}$|^arn:(aws).*:s3-outposts:[a-z\-0-9]+:[0-9]{12}:outpost[/:][a-zA-Z0-9\-]{1,63}[/:]accesspoint[/:][a-zA-Z0-9\-]{1,63}$"
An exception occurred.
my command to run:
Copy code
(course-mlops-zoomcamp)  ✘ 🇹🇭   ~/Github/MLOps/course-mlops-zoomcamp/03-orchestration   main ±  prefect deployment build ./prefect_deploy.py:main \
--name xgboost_optimization \
--tag dev \
--infra process \
--storage-block s3/mlflow-artifacts-prem
I used the above command to run and check the status of the Prefect server in the terminal as the image below shows the status seems to work well. but when I go to Prefect UI. It shows nothing from today’s command that I have run. I have filtered only for today’s date. I have tried to change a lot for the s3 but the result is still the same. even for the path from the Prefect UI.
k
Did you run 
prefect deployment apply
after the build command?
s
If I don’t misunderstand. I should have the 
deployment.yaml
in order to run the command 
prefect deployment apply
right? but because of the issue above from the command:
Copy code
prefect deployment build ./prefect_deploy.py:main \
--name xgboost_optimization \
--tag dev \
--infra process \
--storage-block s3/mlflow-artifacts-prem
the command above only generates a 
JSON
file for me. I think it is because the command did not completed yet. For now, I can prove that my flow can run and the Prefect & MLflow remote server works well. my s3 bucket store the artifacts as they should be. but only the deployment build command that is not complete according to the issue from 
S3
name. So the command did not generate 
deployment.yaml
for me. Any ideas about this issue? I took a few days to work with it but still got nothing.
k
Can you show the configuration of your S3 block? It could be that the path you set in the S3 block is the problem
s
This is my block configuration function.
Copy code
bucket_name = "mlflow-artifacts-prem"
AWS_ACCESS_KEY_ID = os.getenv("AWS_ACCESS_KEY_ID")
AWS_SECRET_ACCESS_KEY = os.getenv("AWS_SECRET_ACCESS_KEY")

def get_storage(s3_bucket: str, 
                AWS_ACCESS_KEY_ID: str,
                AWS_SECRET_ACCESS_KEY: str):

    block = S3(bucket_path=s3_bucket, 
            aws_access_key_id=AWS_ACCESS_KEY_ID, 
            aws_secret_access_key=AWS_SECRET_ACCESS_KEY)
    return block

block = get_storage(bucket_name, AWS_ACCESS_KEY_ID, AWS_SECRET_ACCESS_KEY)
Anyway, can I solve this issue? or Am I missing something in my code block?
k
So you bucket path is mlflow-artifacts-prem? Do you have that bucket in your S3
s
yeah. I have already created the S3 before referring to it.
k
Have you tried to add block configuration on the UI?
s
It is already shown in the Prefect UI as well.
but it will show fail of invalid name s3 then the command cannot complete and not generate the deployment.yaml to me.
k
could you take a screenshot of your configuration in the S3 block? You can blur out your configurations if you want to. I just want to double check
s
Hi, Here is my block page in the Prefect UI.
k
ah I see the problem. Your bucket path should be 
mlflow-artifacts-prem
, not 
<s3://mlflow-artifacts-prem>
s
Hmm. I think I have tried this way before. but I will try again.
I’ll update you.
wait. I think my bucket path is as below:
```bucket_name = "mlflow-artifacts-prem"
AWS_ACCESS_KEY_ID = os.getenv("AWS_ACCESS_KEY_ID")
AWS_SECRET_ACCESS_KEY = os.getenv("AWS_SECRET_ACCESS_KEY")
def get_storage(s3_bucket: str,
AWS_ACCESS_KEY_ID: str,
AWS_SECRET_ACCESS_KEY: str):
block = S3(bucket_path=s3_bucket,
aws_access_key_id=AWS_ACCESS_KEY_ID,
aws_secret_access_key=AWS_SECRET_ACCESS_KEY)
return block
block = get_storage(bucket_name, AWS_ACCESS_KEY_ID, AWS_SECRET_ACCESS_KEY)```
Actually, my bucket path doesn’t include the 
s3://
. like the first line from the code snippet above. I think the 
s3://
return from the Class S3 from Prefect docs. prefect.filesystems - Prefect 2.0
k
Hmm. That’s weird. I don’t have 
s3://
when creating an S3 block though
Can you create one directly from the UI?
s
Hi, @Khuyen Tran It’s work now. I think this is my misunderstanding from the first time I created the bucket. Thank you for supporting me. really appreciated. after applying the deployment I should create the work queue and agent to run the pipeline, right?
k
I’m glad that you figured it out. I’m always happy to help. Yes, that’s would be the next step
