Hi @mindovermiles262, since Dapr CLI is a self-contained binary available for all platforms, what is the purpose for having a docker image?

[mindovermiles262]

I have a use case where I want to run a job on my kubernetes cluster using dapr cli. Something like:

apiVersion: batch/v1
kind: Job
metadata:
  name: dapr-cli
spec:
  template:
    spec:
      containers:
      - name: dapr-cli
        image: daprio/cli
        command: ["dapr", "..."]

I did a quick search but couldn't find any existing image with dapr-cli already installed.

@mindovermiles262 how about a workaround like the following?

apiVersion: batch/v1
kind: Job
metadata:
  name: dapr-cli
spec:
  template:
    spec:
      containers:
      - name: dapr-container
        image: alpine:latest  # Maybe try distroless if not alpine, commands below are roughly written
        command:
          - "/bin/sh"
          - "-c"
          - |
            apk add --update --no-cache curl
            curl -fsSL https://raw.githubusercontent.com/dapr/cli/master/install/install.sh | /bin/sh # or you can simply wget the binary
            dapr command
      restartPolicy: Never
  backoffLimit: 1

Sure, that would work, but it seems like the cli should be available as a container

If there are more use-cases or requirements from the community I'd be happy to vote in favor. For one specific use case it might be an overkill to maintain yet another GitHub pipeline and have yet another Docker image (which will support a single platform - linux/amd64 as per this PR).

^Just my opinion, maintainers might have something else to add.

Fair enough. Let me move this to an Issue for future reference. Thanks
