default to Fedora 24 Using 24 works around a bug in 25 that prevents `dnf` from working unless you import the Fedora GPG key, which is hard to instruct users to do due to the interactive nature of toolbox
toolbox is a small script that launches a container to let you bring in your favorite debugging or admin tools.
$ /usr/bin/toolbox Spawning container core-fedora-latest on /var/lib/toolbox/core-fedora-latest. Press ^] three times within 1s to kill container. -bash-4.3# yum install tcpdump ... -bash-4.3# tcpdump -i ens3 tcpdump: verbose output suppressed, use -v or -vv for full protocol decode listening on ens3, link-type EN10MB (Ethernet), capture size 65535 bytes
toolbox uses a Fedora-based userspace environment by default, but this can be changed to any Docker image. Simply override environment variables in $HOME/.toolboxrc:
core@core-01 ~ $ cat ~/.toolboxrc TOOLBOX_DOCKER_IMAGE=ubuntu-debootstrap TOOLBOX_DOCKER_TAG=14.04 core@core-01 ~ $ toolbox Spawning container core-ubuntu-debootstrap-14.04 on /var/lib/toolbox/core-ubuntu-debootstrap-14.04. Press ^] three times within 1s to kill container. root@core-01:~# apt-get update && apt-get install tcpdump
Set an /etc/passwd entry for one of the users to /usr/bin/toolbox:
useradd bob -m -p '*' -s /usr/bin/toolbox -U -G sudo,docker
Now when SSHing into the system as that user, toolbox will automatically be started:
$ ssh bob@hostname.example.com CoreOS alpha (633.1.0) ... Spawning container core-fedora-latest on /var/lib/toolbox/core-fedora-latest. -bash-4.3 # yum install emacs -bash-4.3 # emacs /media/root/etc/systemd/system/docker.service
Please use the CoreOS issue tracker to report all bugs, issues, and feature requests.
