When deploying kubeless throws: spec.template.spec.containers[0].image: Required value
When attempting to deploy a simple, health check application, kubeless throws the following errors:
time="2021-06-02T00:40:54Z" level=error msg="Function can not be created/updated: Deployment.apps \"hello\" is invalid: spec.template.spec.containers[0].image: Required value" pkg=function-controller
time="2021-06-02T00:40:54Z" level=error msg="Error processing kubeless/hello (giving up): Deployment.apps \"hello\" is invalid: spec.template.spec.containers[0].image: Required value" pkg=function-controller
ERROR: logging before flag.Parse: E0602 00:40:54.927898 1 function_controller.go:185] Deployment.apps "hello" is invalid: spec.template.spec.containers[0].image: Required value
Meanwhile the sls command line sits and waits for the hello application to start up, looking for the pod. I thought that this initially was something simple, like #165 but then I restructured my application to not have folders and got the exact same errors. Any Ideas?
For reference, my serverless.yml, kubeless-deployment and file are pasted below:
