This is all resolved with the addition of curl and tar.

This is clearly not the experience we want our users to have when targeting nanoserver-they’d end up having to download the much larger servercore image. Instead, users would have to rely on using a separate image with PowerShell as the “builder” image to accomplish constructing an image. If you’re familiar with writing dockerfiles, you’ll know that it’s common practice to pull in all the packages (node, mongo, etc.) you need and install them. PowerShell is a whopping 56 Mb (given that the total size of the nanoserver image is 200 Mb…that’s quite the savings!) But the consequence of removing PowerShell meant there was no way to pull down a package and unzip it from within the container. PowerShell was one of the components that was put on the chopping block for our nanoserver image. We threw out all components we felt were not mission-critical for the container image. NET core but, in keeping with the minimalism, we’ve tried to slim down the image size as much as possible. On the opposite end of the spectrum is nanoserver, which is built to be lightweight with as minimal a memory footprint as possible. The servercore image is the larger of the two and has support for such things as the full. We offer two base images for our containers: windowsservercore and nanoserver. Instead, we can invoke the tools like so: Background Now that we’re shipping these tools inbox, you no longer need to worry about using a separate container image as the builder when targeting nanoserver-based containers. PowerShell does already offer similar functionality (it has curl and it's own file extraction utilities), but we recognize that there might be instances where PowerShell is not readily available or the user wants to stay in cmd. Now not only will you be able to perform file transfers from the command line, you'll also be able to extract files in formats in addition to.

Pro tip: "tar" is not POSIX either! Use " pax" instead.Beginning in Insider Build 17063, we’re introducing two command-line tools to the Windows toolchain: curl and bsdtar. Note: As of 2022, Project Gutenberg no longer seems to support insecure downloads over Port 80, so the script example below has been updated with a HTTP mirror. Pretty sure POSIX awk does not support networking and I do not recall seeing anything about it in " The AWK Programming Language" but it has been a while. GNU awk ("gawk") can do it, however the odds of having gawk and nothing more convenient like curl or wget seems slim to me. Of course, you still need the proper permissions to read / write to the socket. You can test for both of them (as many have suggested), but to be certain you would either need to install something or write something.Ī shell with tcp socket support (like ksh93 or Bash) should let you write a function call in a pinch. uucp is standard, but I do not know if you could even make that work without config changes on both ends. To my knowledge, there is no "tcp" file transfer tool defined by POSIX at all. Various GNU/Linux distros may include curl and/or wget, but YMMV.įreeBSD comes standard with the " fetch" tool for cases like this and OpenBSD comes with a souped-up " ftp" client that can do the job with it's "AUTO-FETCHING" feature.
It seems like an odd oversight to me, but that is how it is. Neither is ftp, ssh / scp / sftp, rsync, telnet, nc / netcat, openssl, or probably any related tool that comes to mind. Neither curl nor wget are "guaranteed" to be installed anywhere, especially on proper UNIX systems.
