Install 'locales' on alpine (node:8-latest) Docker image

Question

I'm trying to use alpine (nodeJS) docker image, but I do get the error /bin/sh: apt-get: not found. So what would be the equivalent commands for doing this in alpine?

FROM node:8.6-alpine
ARG APP_LOCALE=en_US
ARG APP_CHARSET=UTF-8

RUN apt-get install locales
RUN locale-gen ${APP_LOCALE}
RUN localedef ${APP_LOCALE}.${APP_CHARSET} -i ${APP_LOCALE} -f ${APP_CHARSET}

Alpine linux uses another package manager. https://wiki.alpinelinux.org/wiki/Alpine_Linux_package_management
