I’ve been having a bit of trouble with this myself and, long story short, I would encourage you to ask if it’s really worth the hassle. Numpy is enormous when you start adding things to the stack like pandas, gpus, and scipy so the benefit of building it on alpine is limited, the savings over … Read more
Debian based images use only python pip to install packages with .whl format: Downloading pandas-0.22.0-cp36-cp36m-manylinux1_x86_64.whl (26.2MB) Downloading numpy-1.14.1-cp36-cp36m-manylinux1_x86_64.whl (12.2MB) WHL format was developed as a quicker and more reliable method of installing Python software than re-building from source code every time. WHL files only have to be moved to the correct location on the target … Read more
By default, if using the net package a build will likely produce a binary with some dynamic linking, e.g. to libc. You can inspect dynamically vs. statically link by viewing the result of ldd output.bin There are two solutions I’ve come across: Disable CGO, via CGO_ENABLED=0 Force the use of the Go implementation of net … Read more
Alpine docker image doesn’t have bash installed by default. You will need to add the following commands to get bash: RUN apk update && apk add bash If you’re using Alpine 3.3+ then you can just do: RUN apk add –no-cache bash To keep the docker image size small. (Thanks to comment from @sprkysnrky) If … Read more
On Alpine Linux, the not found error is a typical symptom of dynamic link failure. It is indeed a rather confusing error by musl’s ldd linker. Most of the world Linux software is linked against glibc, the GNU libc library (libc provides the standard C library and POSIX API). Most Linux distributions are based on … Read more
Yes there is, I’ve used a custom built glibc to install a JRE on it. You can find it here You can use wget or curl to get the code and apk to install them UPDATED commands see comments below apk –no-cache add ca-certificates wget wget -q -O /etc/apk/keys/sgerrand.rsa.pub https://alpine-pkgs.sgerrand.com/sgerrand.rsa.pub wget https://github.com/sgerrand/alpine-pkg-glibc/releases/download/2.28-r0/glibc-2.28-r0.apk apk add glibc-2.28-r0.apk … Read more
