  • Temporary Namespace for Kubernetes

    To set a temporary namespace for k8s simply create an alias like so:

  • 413 Request Entity Too Large in nginx k8s ingress

    I wanted to enable a file upload. Whenever I was uploading I received the error code “413 Request Entity Too Large” from the nginx ingress controller in kubernetes. I found the solution here. Use the following annotation to allow unlimited upload size: "0"
    In my case, the ingress file definition now looks like this:
    apiVersion: # for versions before 1.14 use extensions/v1beta1
    kind: Ingress
      name: my-name
      namespace: my-namespace
      annotations: /$1 "0"
      # The specs, omitted for readability
