BuildKit

This Task builds source into a container image using Moby BuildKit.

See also buildkit-daemonless for the daemonless version of this task.

Install

Step 0: Create mTLS secrets

You need to determine the SAN of the BuildKit daemon Service and create mTLS certificates. In this example, we use buildkitd as the SAN.

$ ./create-certs.sh buildkitd
$ kubectl apply -f .certs/buildkit-daemon-certs.yaml
secret/buildkit-daemon-certs created
$ kubectl apply -f .certs/buildkit-client-certs.yaml
secret/buildkit-client-certs created
$ rm -rf .certs

Step 1: Deploy BuildKit daemon

Two types of the daemon manifests are included:

deployment+service.rootless.yaml (recommended): Run the daemon as a non-root user. Using Ubuntu nodes is recommended. Needs sysctl configuration for Debian hosts and RHEL/CentOS 7 hosts. Does not work on Google COS.
deployment+service.privileged.yaml: Run the daemon as the root user with securityContext.privileged=true. Try this version if deployment+service.rootless.yaml does not work or too slow.

$ kubectl apply -f deployment+service.rootless.yaml
deployment.apps/buildkitd created
service/buildkitd created

The number of replicas can be adjusted as you like:

$ kubectl scale --replicas=10 deployment/buildkitd

See also BuildKit documentation for the further information about the manifests.

Step 2: Install the task

$ kubectl apply -f task.yaml
task.tekton.dev/buildkit created

Inputs

Parameters

DOCKERFILE: The path to the Dockerfile to execute (default: ./Dockerfile)
