Description
Thanks to #28 it is possible to install additional packages using --build-arg ADDITIONAL_PACKAGE=<package-names>
. However, you can only install packages from the default repositories defined in /etc/apk/repositories
.
Possible Solution
Add another build argument ADDITIONAL_REPOSITORY
, whose content is appended to /etc/apk/repositories
and update the package list. This might be accomplished by modifying an existing installation statement in the Dockerfile
RUN apk --no-cache add ca-certificates ${ADDITIONAL_PACKAGE}
to
ARG ADDITIONAL_REPOSITORY
RUN printf ${ADDITIONAL_REPOSITORY} >> /etc/apk/repositories && \
apk --update --no-cache add ca-certificates ${ADDITIONAL_PACKAGE}
Thereby, you can build it using two additional repositories
faas-cli build \
--build-arg ADDITIONAL_REPOSITORY="http://dl-cdn.alpinelinux.org/alpine/edge/main\nhttp://dl-cdn.alpinelinux.org/alpine/edge/community" \
--build-arg ADDITIONAL_PACKAGE=<package-name> \
-f <yml>
