Test the registry

Pre-requisites

Open a port forward

kubectl port-forward -nlocal-container-registry svc/local-container-registry 5000:5000

Optional: Open the logs

kubectl logs -f -nlocal-container-registry deploy/local-container-registry

Login to the registry, push and pull image

LCR_ENDPOINT="local-container-registry.local-container-registry.svc.cluster.local:5000"
LCR_CONFIG=".ignore.local-container-registry.yaml"

read -rp "container engine? (docker, podman) " CONTAINER_ENGINE

curl -k -u"$(yq '"\(.username):\(.password)"' "${LCR_CONFIG}")" \
    "https://${LCR_ENDPOINT}/v2/"

ADDITIONAL_FLAGS=""

if [ "${CONTAINER_ENGINE}" == "podman" ]; then
  ADDITIONAL_FLAGS="--tls-verify=false"
fi

yq '.password' "${LCR_CONFIG}" \
    | ${CONTAINER_ENGINE} login \
        "${LCR_ENDPOINT}" \
        -u="$(yq '.username' "${LCR_CONFIG}")" \
        --password-stdin \
        ${ADDITIONAL_FLAGS}

NEW_IMAGE="${LCR_ENDPOINT}/registry"

${CONTAINER_ENGINE} tag registry:2 "${NEW_IMAGE}"
${CONTAINER_ENGINE} push "${NEW_IMAGE}" ${ADDITIONAL_FLAGS}
${CONTAINER_ENGINE} pull "${NEW_IMAGE}" ${ADDITIONAL_FLAGS}

Simply curl the registry

LCR_ENDPOINT="local-container-registry.local-container-registry.svc.cluster.local:5000"
LCR_CONFIG=".ignore.local-container-registry.yaml"
CREDENTIALS="$(yq '"\(.username):\(.password)"' "${LCR_CONFIG}")"

curl -k -u"${CREDENTIALS}" "https://${LCR_ENDPOINT}/v2/"
