Building k8s-dns-node-cache-arm64

TurnToJPG -->

Steps

Clone the source code from github:

# git clone https://github.com/kubernetes/dns.git
# git checkout tags/1.15.1 -b local_1.15.1

Modify the source code:

# vim Makefile
BINARIES := \
    node-cache
#    e2e \
#    ginkgo \
#    sidecar-e2e


CONTAINER_BINARIES := \
    node-cache

ARCH ?= arm64

Now building via:

# make build
# make containers

Will get error, now copy the generated node-cache file into destination directory:

# cp ./.go/bin/node-cache bin/arm64/

Edit the dnsmasq’s Makefile via:

# vim images/dnsmasq/Makefile

make will also get error, manually compile the dnsmasq:

# cd ./images/dnsmasq/_output/arm64/dnsmasq-2.78
# make
# cp src/dnsmasq ../docker

Now go the project root directory and make containers:

# make containers
# docker images  | grep dns
staging-k8s.gcr.io/k8s-dns-dnsmasq-arm64      1.15.1-dirty         fbb04ccb60e6        About an hour ago   3.63MB
staging-k8s.gcr.io/k8s-dns-node-cache-arm64   1.15.1-dirty         bf6131745b5e        About an hour ago   71.9MB

Now replace the dns-node-cache default to our own build-out version we could enable node-cache working on arm64.
