radial/busyboxplus repository overview

⁠Busyboxplus Images

This repository creates multiple flavors of busybox images with full-chains from scratch using Buildroot⁠. It is part of the Radial⁠ suite of images and tools and was compiled to make use of the small size of Busybox with some additional specialty items.

My goal was to make lightweight busybox-based volume-containers solely for managing the configuration "Hub" containers and shared/bind-mounted volume "Axle" containers for the container that actually runs the application, or "Spoke" container.

The Busyboxplus flavors are:

###Base Image

Available via docker pull radial/busyboxplus:base.

• System
  • Wide character support
• Internet/networking
  • IPV4, IPV6

This image is the basis for the axle-base⁠ image. At 1.27mb, it is the smallest busybox build of all the flavors.

###cURL Image

Available via docker pull radial/busyboxplus:curl. In addition to the base image, the cURL image adds:

• Curl (7.35.0)/libcurl (7.35.0), built with OpenSSL (1.0.1f, includes ca-certificates), zlib (1.2.8), and Libssh2 (1.4.3)
  • Protocols: dict file ftp ftps gopher http https imap imaps pop3 pop3s rtsp scp sftp smtp smtps telnet tftp
  • Features: IPv6 Largefile NTLM SSL libz TLS-SRP

This image was created as an alternate for those only needing to use cURL to extract their configuration in their Hub containers⁠. This image, at 4.23mb, is a significant size savings over the following git image.

###Git Image

Available via docker pull radial/busyboxplus:git. In addition to the base and cURL image (git requires cURL anyway for http/s support), the git image adds:

• Git (1.8.3.5)
  • built with OpenSSL (1.0.1f, includes ca-certificates) and zlib (1.2.8)
  • Protocols: local, git, http, https, (no SSH)
    • This build is made for importing repositories securely, so the above protocols will work for git clone and git fetch for example but will be lacking if you attempt a standard workflow (cannot push new commits securly to remote server).
  • This is a bare minimum package made to support all the core git functions as found in git --help. All other tools and extras found in the git suite have been stripped to keep the image size to a minimum. Additional git features such as the server backends, cvs and shell login, svn support, and some others can be easily added back in at a cost of about 0.5 - 1mb of image size per item. Feel free to reach out with requests for custom git builds.

The git image is default Hub container⁠ image and weighs in at around 12.86mb. Hub containers have the ability to access other containers/servers/web-locations to grab and update configuration using git and/or cURL. The possibilities are pretty extensive!
