Steps to Reproduce:
Create product

   Create repository and sync to source

1. hammer repository create \
   --content-type "docker" \
   --organization myorg \
   --product "Product_Busybox_Container" \
   --url "https://registry-1.docker.io" \
   --name "library/busybox" \
   --docker-upstream-name "library/busybox" \
   --label "library_busybox" \
   --include-tags "stable, 1.35.0"

1. hammer repository synchronize --name "library/busybox" --product "Product_Busybox_Container" --organization myorg

Create content view
