Have you had a proper look at Gitlab CI? It know, it's hard to make that sound credible with all that's going on with Gitlab right now but I found their CI to be the best around and you can even use your own machines to run stuff on.
To be fair, GitLab's current issues are purely operational on the GitLab.com side: their backup strategy and testing needs some work, but the product is really solid and most of the features are already there in GitLab CE.
For me, getting GitLab up and running on kubernetes was a breeze (using the popular docker image [1]) and my `pg_dump; duplicity;` backups are chugging right along. I haven't played with their CI yet, but I'm pretty excited to see how much it can do for me automatically managing my cluster.
Yes, out of all solutions I'm most excited about GitlabCI and Drone.io
I've worked with a self hosted Gitlab instance before and that was nice, but I'm not quite sure how well the Gitlab CI would integrate when the code is on github.
