Skaffold supports building in cluster via [Kaniko]({{< relref "/docs/builders/builder-types/docker#dockerfile-in-cluster-with-kaniko" >}}) or [Custom Build Script]({{<relref "/docs/builders/builder-types/custom#custom-build-script-in-cluster" >}}).
To configure in-cluster Build, add build type cluster to the build section of skaffold.yaml.
build:
cluster: {}
The following options can optionally be configured:
{{< schema root="ClusterDetails" >}}
Skaffold can build multiple artifacts in parallel, by settings a value higher than 1 to concurrency.
For in-cluster builds, the default is to build all the artifacts in parallel. If your cluster is too
small, you might want to reduce the concurrency. Setting concurrency to 1 will cause artifacts to be built sequentially.
{{<alert title="Note">}} When artifacts are built in parallel, the build logs are still printed in sequence to make them easier to read. {{</alert>}}
