As mentioned in the documentation, Additional Extensions section:

When using the Alpine variants, any postgres extension not listed in postgres-contrib will need to be compiled in your own image (again, see github.com/appropriate/docker-postgis for a concrete example).

For debian based here is the docker image:

https://github.com/appropriate/docker-postgis/blob/f6d28e4a1871b1f72e1c893ff103f10b6d7cb6e1/10-2.4/Dockerfile

If you want to bundle Postgis with PostgreSQL Alpine image you have build it.

In short:

To get the latest list of available packages, use the update command.

it is similar to the Debian apt-get update that you do before apt-get install my_package.

from https://wiki.alpinelinux.org/wiki/Alpine_Linux_package_management#Update_the_Package_list:

Update the Package list

Remote repositories change as packages are added and upgraded. To get the latest list of available packages, use the update command. The command downloads the APKINDEX.tar.gz from each repository and stores it in the local cache, typically /var/cache/apk/, /var/lib/apk/ or /etc/apk/cache/.

apk update

Tip: If using remote repositories, it is a good idea to do an update just before doing an add or upgrade command. That way you know you are using the latest software available.

If you want to get puppeteer to work on alpine, try using an older version of puppeteer that works with an older version of Chrome. The newest version of Chrome supported on Alpine is 63, which was the version of Chrome used during the development of puppeteer version 0.11.0.

You can easily create your own Alpine Linux ISO image using script alpine-make-vm-image.

Example:

python:3.5-alpine3.4 docker image is based on Alpine v3.4. lapack-dev package was appeared only in Alpine v3.5. So, my suggestion is to install lapack-dev package from the nearest repository by time. In this case you shouldn't face issues with outdated dependencies. And it works pretty well.

The final Dockerfile is:

You have an issue with the following packages: apache2-suexec, host, lpr and time.

Alpine has some other package structure than main Linux OSs:

• apache2-suexec is a part of apache2 package;
• host is a part of bind-tools package;
• lpr is a part of cups-client package;
• time is already in alpine image. It uses busybox's time utility.

So, the final Dockerfile is:

os.stat resolves its target. Use os.lstat when you want info on the symlink itself.

Here's the documentation:

os.stat(path)

Perform the equivalent of a stat() system call on the given path. (This function follows symlinks; to stat a symlink use lstat().)

vs

os.lstat(path)

Perform the equivalent of an lstat() system call on the given path. Similar to stat(), but does not follow symbolic links. On platforms that do not support symbolic links, this is an alias for stat().
