Question

hey I am trying to do prefect deployment build with github and docker blocks I am getting a `too many values to unpack expected 2 ` error anyone know what I might be doing wrong im on version 2 8 6

Adam · Answer

I think it has to do with my first line getting the flow from a file in git

Nate · Answer

hi < Adam> can you share your `prefect deployment build` command

Adam · Answer

```prefect deployment build <https github com docker prefect test py run dbt> n dbt deploy docker sb github repository git repo ib docker container prefect docker o prefect docker deployment apply```

Adam · Answer

I ran this with a local file and it was fine so im pretty sure it has to do with me trying to pull it from github

Nate · Answer

yep we interpret that first argument like `local filepath containing flow flow fn` so when <https github com PrefectHQ prefect blob main src prefect cli deployment py L1106|this> happens a link wouldn t work

Adam · Answer

so then how do I deploy a flow needs to be version controlled on git

Adam · Answer

I think thats where I am getting tripped up want to store it in git so when we change its version controlled

Nate · Answer

the github block is nice in this regard you can just pass a relative path if you run `deployment build` from that repo or if you clone the repo in CI or something and then when your deployment runs and clones your repo via your github storage block it will know where to look relative your repo root so in your case if you re at your local `bi etl` repo root you can do ```prefect deployment build prefect docker prefect test py run dbt n dbt deploy docker sb github repository git repo ib docker container prefect docker o prefect docker deployment apply``` assuming your project is organized like ```bi etl prefect docker prefect test py```

Nate · Answer

worth noting that we re about to release a simplified pattern for git based deployments like this in the very near future like in the next week or so

Adam · Answer

ahhh so run this from my repo it should work with the relative path maybe thats what I was also missing

Adam · Answer

and awesome I look forward to it It seems like this docker block is already going to save me some time from figuring out how to do that stuff lol

Adam · Answer

Appreciate your help on this

Nate · Answer

sure thing smile anytime

Adam · Answer

and that worked thanks

Adam · Answer

the blocks seem to be having issues or i dont know how to use them lol so really looking forward to it being simplified

Adam · Answer

getting an `KeyError No class found for dispatch key github repository in registry for type Block ` error when I run the deploy

Nate · Answer

ahh sorry this confusion is part of the motivation behind the simplification we re rolling out `github repository` is a block that s defined in the `prefect github` collection a separate pypi package that would need to be installed where your agent runs there is another block `github` that I would recommend using instead its a part of prefect core so nothing else to install I will go ahead and raise this so we can remove `github repository` from the block catalogue here since that is definitely confusing

Adam · Answer

yeah I was playing with both as I had issues different ones on each

Adam · Answer

im having fun over here if you cant tell laughing

Adam · Answer

and finally success

Nate · Answer

ayy glad you got it working do you might sharing what your final hurdle was here in case someone else runs into a similar problem before we roll out the simplified pattern smile

Adam · Answer

I was an idiot and had the git repo wrong and then missed a in the pip packages for dbt
