问题
If I'm using Alpine 3.8, how can I add a specific package from the Alpine Edge repository? Is this even supported? There is no equivalent of backports, from what I can see.
I want to add the new version of this: https://pkgs.alpinelinux.org/package/edge/community/armhf/librdkafka
And not the older version in the 3.8 repo: https://pkgs.alpinelinux.org/package/v3.8/community/s390x/librdkafka
回答1:
You could specify the exact repo to apk, using the --repository parameter.
In your case:
apk add librdkafka --repository=http://dl-cdn.alpinelinux.org/alpine/edge/main
回答2:
Edge repository may be enabled permanently. Just do the following:
sed -i '/edge/s/^#//' /etc/apk/repositories

You can also add the repo:
echo "@testing http://dl-cdn.alpinelinux.org/alpine/edge/main" >> /etc/apk/repositories
and reference it with apk via @testing. Example:
apk add package-name@testing
