⁠Note about image size

All images are built to have the smallest image size possible without sacrificing functionality. To that end, almost every image begins either with the Alpine Linux base image or from scratch.

⁠Note about autobuilds on DockerHub

DockerHub currently supports autobuilding images for the x86 architecture only. Therefore, autobuilds will not be used. The images will be built elsewhere and pushed to DockerHub.

⁠Image Variants

⁠openssh

The openssh image comes in two variants(and three tags) currently.

• openssh:alpine (based on Alpine Linux⁠)
• openssh:alpine-bash (based on Alpine Linux⁠, with bash installed)
• openssh:debian (based on Debian Stretch⁠)

⁠openssh:alpine

This is the defacto image. If you are unsure about what your needs are, you probably want to use this one.

This image is based on the popular Alpine Linux project⁠, available in the alpine official image⁠. Alpine Linux is much smaller than most distribution base images (~5MB), and thus leads to much slimmer images in general.

This variant is highly recommended when final image size being as small as possible is desired. The main caveat to note is that it does use musl libc⁠ instead of glibc and friends⁠, so certain software might run into issues depending on the depth of their libc requirements. However, most software doesn't have an issue with this, so this variant is usually a very safe choice. See this Hacker News comment thread⁠ for more discussion of the issues that might arise and some pro/con comparisons of using Alpine-based images.

To minimize image size, it's uncommon for additional related tools (such as git or bash) to be included in Alpine-based images. Using this image as a base, add the things you need in your own Dockerfile (see the alpine image description⁠ for examples of how to install packages if you are unfamiliar).

⁠openssh:alpine-bash

This image is slightly larger than the default alpine image as it has bash installed in the image. For most cases, you will not need to use this image unless you need something that requires the presence of bash. In the future, this image will be removed.

⁠openssh:debian

This image is based on the Debian Stretch Slim distribution. This image is considerably larger than the Alpine Linux image.

⁠License

As with all Docker images, these likely also contain other software which may be under other licenses (such as Bash, etc from the base distribution, along with any direct or indirect dependencies of the primary software being contained).

As for any pre-built image usage, it is the image user's responsibility to ensure that any use of this image complies with any relevant licenses for all software contained within.
