Simple apk package cache for Alpine Linux
Start apk-cache container:
docker run -d --name=apk-cache quay.io/vektorcloud/apk-cache:latest
After apk-cache is up, start any subsquent containers with a link to the cache:
docker run -ti --link apk-cache:dl-cdn.alpinelinux.org alpine:latest /bin/sh
To alternatively avoid having to link every running container, publish port 80 to the host:
docker run -d -p 80:80 --name=apk-cache quay.io/vektorcloud/apk-cache:latest
and override resolution of dl-cdn.alpinelinux.org using the IP of the Docker host via dnsmasq or the docker run option --add-host dl-cdn.alpinelinux.org:<HOST-IP>
