Hi ! I have tried to install Metaflow in an on-prem fashion following this guide :

<https://github.com/outerbounds/metaflow-with-airflow-minio>

• created a cluster using microk8s (because i had other apps running but deployment went just fine) • installed and forwarded MinIO and ran the

create-bucket.py

script without problem • created the secret using my own secrets • installed the metaflow suite using the command described in step

9

and tried to run a flow. (i forwarded all ports manually before creating the ingress routes just to be sure) the flow runs just fine and i can see the results by browsing the MinIO interface. But i cant access it from the UI. the

pod/metaflow-metaflow-ui

keeps on crashing with this trace :

wich resembles this issue on the metaflow-tools github https://github.com/outerbounds/metaflow-tools/issues/48 Does anyone knows how to fix it ?
