Unable to install Dagster via HELM

I am trying to install Dagster via HELM on AWS EKS by following this documentation: https://docs.dagster.io/deployment/guides/kubernetes/deploying-with-helm

I am using EKS version 1.23 and the Dagster HELM chart version 1.0.12

I install dagster and then get the following errors, but I’m not sure why this is happening.

All three pods have one failed container: Daemon -

Dagit -

Dagster user deployments -

The error log in all the Daemon and Dagit failed containers is: exec /bin/bash: exec format error

The error log in the user deployment container is: exec /usr/local/bin/dagster: exec format error I am not sure as to what the problem could be given that I am following the tutorial. Is it an EKS / HELM incompatibility issue?

@madhur-tandon You are right 😃 My EC2 instances were of type “g” which are ARM based, and the official Dagster images are built on AMD architectures. Switching to type “a” EC2 solved it for me. I am closing this issue.

It’s probably because you guys are building the docker image on an M1 Mac i.e. ARM architecture while the EC2 machines on the EKS cluster are Linux machines with the x86 or perhaps amd64 architecture. You should probably use the --platform argument while building your image with docker.
