[rusenask]

There was a bug in version parsing, fixed it with #18. But there is another issue here - looks like your currently deployed image is untagged: gcr.io/stemnapp/alpine-ap should be something like gcr.io/stemnapp/alpine-ap:v0.0.824.

Furthermore, I am refactoring image parsing so it's a lot more robust.

[rusenask]

should be fixed in #26
