Update dockerhub to 1.7

[hsharrison]

Hi, thanks for the tool! This would be really useful for my team, but the feature in 1.7 is key for us. Can you build and push that version to dockerhub please?

@hsharrison Hi, will do this over the weekend.

Hi @sukeesh, just a friendly reminder about this 😄

Could you please push the button so 1.7 gets pushed up to dockerhub? Thanks :)

FYI we've been using Robusta instead, obviously quite heavy if your use case is narrow but if you're lacking a monitoring solution more generally then Robusta is great and has a useful failed job alert.
