What is Alpine Linux?
Alpine Linux is a Linux distribution built around musl libc and BusyBox. The image is only 5 MB in size and has access to a package repository that is much more complete than other BusyBox based images. This makes Alpine Linux a great image base for utilities and even production applications. Read more about Alpine Linux here and you can see how their mantra fits in right at home with Docker images.
How to use this image
Use like you would any other base image:
FROM alpine:3.3 RUN apk add --no-cache mysql-client ENTRYPOINT ["mysql"]
This example has a virtual image size of only 16 MB. Compare that to our good friend Ubuntu:
FROM ubuntu:14.04 RUN apt-get update \ && apt-get install -y mysql-client \ && rm -rf /var/lib/apt/lists/* ENTRYPOINT ["mysql"]
This yields us a virtual image size of about 232 MB image.
This image is well documented. Check out the documentation at Viewdocs.

This image is officially supported on Docker version 17.03.0-ce.

With the latest version (3.5), I am experiencing below error.

Can anyone please help me on resolving it and moving forward
does anyone know what the root password is ?
I search php7-redis and found this:
In Dockerfile I do apk update && apk upgrade.
But alpine:latest and alpine:edge can't find this package.
May be I doing something wrong?
And thank you for avesome distrib, for your job.
Hi! Is there any plan to officially support a "glibc" version any time in the future? The official busybox images have a "glibc" version, but they don't have a default package manager like y'all, and I doubt the same community support. Official support for a solution that has "glibc" and a package manager would really help me make a case for my company to adopt this as a viable base image for our production needs. Thanks in advance!!!
I was trying the docker tutorial (self paced) and was unable to complete the tutorial's first docker app creation due to the builder failed at RUN APK ADD PY-PIP STEP giving unsatisfiable constraint error.
I resolved this issue by building the docker with 3.4 image instead of latest (3.5) which just goes fine.
Thanks!!! Kudos to the team for quick Response !!!
Please upgrade the image to v3.5 as we are not able to use php7 on v3.4. When can we expect an upgrade on this.
Please update the image to v3.5.
Alpine 3.5 was released yesterday. Waiting for docker image update!
