Slow build time on Minikube reported

[nicolaferraro]

I've got some reports of build time on Minikube taking more than 10 mins recently.

The slowest phase seems to be Kaniko downloading the base image and pushing to the internal registry. It may also be slow because the Kaniko cache is now disabled, but 10 mins with a fast internet connection (200 Mbps) is not acceptable even for the first build.

I wonder if we can find a faster strategy for Minikube users or for the development phase, when you want to run everything as soon as possible.

Running into very slow builds on my local machine using minikube.

1. hello.groovy example initially took over 5 minutes to get started.
2. Rest-with-undertow is taking a massive amount of time and I gave up after 10 minutes.

See my log below;

I am on a 100 Mbps fibre connection. I checked and downloads where not bad on other sites.

So I did some digging.

I had Istio installed in demo mode(learning Knative,Istio, Kamel and Quarkus atm) and this seems to have affected the build times.

Installing Istio with a minimal profile sped up the quite a bit.

Note that the KNative documentation uses Helm install for Istio which is being deprecated.

@Namphibian we are working on #1256 that should ideally improve the build time and open new possibilities, like possibly interacting directly with the Docker daemon on Minikube for faster development cycles.

[astefanutti]

Buildah support has been merged in #1256, which now becomes the default builder on Minikube. It should improve the average build time. More optimisations will be delivered as part of #681, in order to achieve average build time below a minute.

[nicolaferraro]

Fixed by #1259
