Travis will not work :)

Can you test in your own repo and confirm if the GHCR image looks as expected?

Please could you use GHCR instead of Docker Hub?

[cpanato]

@alexellis updated to use GHCR instead of docker.io

No need to change this now, but if github.repository_owner gives the same value as steps.get_repo_owner.outputs.repo_owner, then we could probably remove that step in the future. I think github.repository_owner must be new, because we didn't find it when looking before? cc @utsavanand2

i thought that, but i saw an existing example in another openfaas repo that I followed, but I think we can update all to use the envs the github provide, including the tag

I can open a follow up or if you would like

Let's see if it worked? https://github.com/alexellis/derek/actions/runs/658244376
