Example Build¶

This example uses the vh_dbus template from the c3-templates repository to demonstrate a VHT 2.0 image build and registry push.

Clone the Example¶

git clone git@bitbucket.org:veea/c3-templates.git
git checkout feature/VHP-7404-vht-2.0-extensions
cd c3-template/vh_dbus

Note

If the VHT 2.0 template branch or directory layout has moved, use the current vh_dbus VHT 2.0 template location. The build and registry commands below stay the same.

Build for an Insecure Registry¶

Build and push a multi-architecture image:

docker buildx build \
  --builder insecure-builder \
  --platform linux/amd64,linux/arm/v7,linux/arm64/v8 \
  --push -t 192.168.1.29:5001/<namespace>/vh_dbus:latest .

Inspect the pushed manifest:

docker manifest inspect --insecure 192.168.1.29:5001/<namespace>/vh_dbus:latest

The --insecure flag is required for an insecure registry.

Build for a Secure Registry¶

Login to Docker Hub:

docker login

Or use a PAT from an environment variable:

export DOCKER_CONTEXT=default
echo ${PAT} | docker login -u <username> --password-stdin docker.io

Build and push:

docker buildx build \
  --builder secure-builder-using-public-trusted-certs \
  --platform linux/amd64,linux/arm/v7,linux/arm64/v8 \
  --push -t docker.io/<namespace>/vh_dbus:latest .

Inspect the pushed manifest:

docker manifest inspect docker.io/<namespace>/vh_dbus:latest

Expected manifest platforms include linux/amd64, linux/arm/v7, and linux/arm64.
