docker build error (2).jpg

Hello, I've been running into this error trying to login to prefect cloud via docker image.
The Dockerfile is simple:

FROM prefecthq/prefect:2.3.2-python3.10
RUN prefect cloud login -k &lt;my api key&gt;

I get the following attached error when running docker build .
I tried using different prefect images with different prefect2 and python versions, but get the same error.

Any idea what could be causing this?

I ran into the same problem. Running those commands instead fixed it for me:
`prefect config set PREFECT_API_KEY=...`
`prefect config set PREFECT_API_URL=...`

To follow up on the cause: the `prefect cloud login` command expects an interactive terminal, because it asks you to pick a workspace and then enter a profile name.

The Docker build environment doesn't provide `/dev/tty`, so the command fails.
