Hello, With some effort, I figured it out myself. I'll reply my own question here for future reference:
The thing that made the difference is to use the right directory structure. If you check out a working copy of the heapster code below $GOPATH/src/k8s.io/heapster, things work smoothly. Perhaps this is obvious for experienced go developers, but it wasn't for me. On my linux box, the following commands are sufficient to build heapster: # Install go apt install golang-go # Edit .profile to set GOPATH and update PATH cat >> ~/.profile <<EOF export GOPATH=$HOME/go export PATH=$GOPATH/bin:$PATH EOF source ~/.profile mkdir -p ~/go/src/k8s.io # Install godep tool go get -u github.com/tools/godep # Check out heapster repository cd ~/go/src/k8s.io git clone https://github.com/kubernetes/heapster.git # Build cd ~/go/src/k8s.io/heapster make regards, Martijn On Monday, 5 December 2016 15:24:33 UTC+1, [email protected] wrote: > Hey all > > I'd like to make some changes to heapster and create a new docker image for > it.
