TL;DR: Check your
Dockerfile (try to build it manually) before anything else!
Today I was struggling with a 400 error:
Exception caught: Request error: POST
https://192.168.99.101:2376/build?t=localhost:5000/eris-django:2.0.1-ivanlla: 400: HTTP 400 Bad Request -> [Help 1]
when building an image with the docker-maven-plugin. After installing and uninstalling docker, cleaning up certificates etc, I figured out my setup had nothing to do with it. Instead, there was a configuration error or the docker file. More specific, I was using
alpine and I forgot the
RUN prefix to a command.
I've tried to dun the build manually and failed. Once I've fixed my
Dockerfile, could run the maven build without a hitch.
