Merge pull request #78 from aaradhak/toolboxarcreate Bug 2093040: Unable to start `toolbox` on RHCOS using `podman` 4.0
rhcos-toolbox is a small script, designed for RHEL CoreOS, that launches a podman 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. [root@localhost ~]# dnf -y install tcpdump ... [root@localhost ~]# 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 REGISTRY=registry.redhat.io IMAGE=rhel7/rhel-tools:latest core@core-01 ~ $ toolbox Spawning a container 'toolbox-test' with image 'registry.redhat.io/rhel7/rhel-tools:latest'
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,rkt
Now when SSHing into the system as that user, toolbox will automatically be started:
$ ssh bob@hostname.example.com Container Linux by CoreOS alpha (1284.0.0) ... Spawning container bob-fedora-latest on /var/lib/toolbox/bob-fedora-latest. Press ^] three times within 1s to kill container. [root@localhost ~]# dnf -y install emacs-nox ... [root@localhost ~]# emacs /media/root/etc/systemd/system/docker.service
