unikraft images build

Build a Unikraft project into a container image.

Code
unikraft images build [<input>] [flags]

Examples

Build the project in the current directory:

Code
unikraft image build .

Build and publish an image from a Kraftfile:

Code
unikraft image build . --output my-org/my-app:latest

Build from a Dockerfile without a Kraftfile:

Code
unikraft image build ./Dockerfile --arch x86_64 --output my-org/my-app:latest

Build with custom build arguments:

Code
unikraft image build ./app --build-arg VERSION=1.2.3 --build-arg COMMIT=abc123

Build with secret and SSH access:

Code
unikraft image build . --secret id=npm,src=$HOME/.npmrc --ssh default=$SSH_AUTH_SOCK

Build for arm64 and publish the image:

Code
unikraft image build . --arch arm64 --output my-org/my-app:latest

Build and save to a local OCI archive:

Code
unikraft image build . --output ./dist/my-app.oci.tar

Options

Code
  --arch ARCH                 Only build the Kraftfile targets of these architectures. Defaults to every declared target. Required when the project declares no targets and no runtime, such as a bare Dockerfile.
  --build-arg BUILD-ARG       Set build-time variables.
  --insecure INSECURE         Allow insecure (HTTP/unverified TLS) connections to registries. Specify hostnames to restrict, or omit to apply to all.

  -o, --output OUTPUT         Output destination
  --secret SECRET             Secret to expose to the build (format: "id=mysecret[,src=/local/secret]").
  --ssh SSH                   SSH agent socket or keys to expose to the build (format: "default|<id>[=<socket>|<key>[,<key>]]").
