Important note: By design, OpenShift 4.x clusters are immutable and rely on Operators to apply cluster changes. In turn, this means that accessing the underlying nodes directly by SSH is not the recommended procedure. Additionally, the nodes will be tainted as accessed.
Therefore, whenever possible, generate a sosreport without using SSH, by spawning a debug pod directly from the
occommand line. See How to generate SOSREPORT within OpenShift4 nodes without SSH for further information.
Only if it's not possible to generate a sosreport without SSH, connect to the OpenShift Container Platform 4.x node where a sosreport shall be generated via SSH. After that, become
root and run the
$ ssh core@NODE # ssh with core user using ssh key specified in install-config.yaml [core@node ~]$ sudo -i [root@node ~]# toolbox Spawning a container 'toolbox-root' with image 'registry.redhat.io/rhel8/support-tools' Detected RUN label in the container image. Using that as the default... Command: /proc/self/exe run -it --name toolbox-root --privileged --ipc=host --net=host --pid=host -e HOST=/host -e NAME=toolbox-root -e IMAGE=registry.redhat.io/rhel8/support-tools:latest -v /run:/run -v /var/log:/var/log -v /etc/machine-id:/etc/machine-id -v /etc/localtime:/etc/localtime -v /:/host registry.redhat.io/rhel8/support-tools:latest
Note: in disconnected environments, it's needed to have the
registry.redhat.io/rhel8/support-toolsmirrored. If the image is already available, create a
/root/.toolboxrcfile within the node as follows before running
$ vi /root/.toolboxrc REGISTRY=private-registry.example.com:5000 IMAGE=rhel8/support-tools
The CLI is now attached to a new bash session within the container and one can execute
[root@node ~]# sosreport -k crio.all=on -k crio.logs=on -k podman.all=on -k podman.logs=on
This will generate the sosreport in
/host/var/tmp directory on the container which maps to
/var/tmp/ on the host.
Once the sosreport was created, run
exit to exit from the container:
[root@node ~]# exit [root@node ~]#
toolbox command runs
podman container runlabel run registry.redhat.io/rhel8/support-tools, which is the replacement for
atomic run registry.redhat.io/rhel7/support-tools from RHEL Atomic Host.
toolbox does not start the debug container as expected, check for a user-created
$HOME/.toolboxrc file that could be overriding the default values of the
In disconnected environments, it will be needed to create that file to refer to the mirrored image.
