How to draw a gradient border button?

My Problem

Last week, my partner showed me his design for our application. Everything is great, easily implemented with some custom controls. But wait, something is not in my knowledge.

A button with gradient border. Never try it before. Up to now, I just created gradient background views 2 times in previous projects. Googled and found some good results.

Attach a shell to the docker container

Install GDB (needed by pyrasite)

apt-get update && apt-get install gdb

French Press Coffee

• grind super coarse
• add just enough boiling water to cover grounds. Steep for 30s.
• fill press to top. Stir to get a good vortex, which will pull the grounds down into a "cone" on the bottom.
• Leave for ~5mins
• skim floating grounds off the top with a spoon
• press
