This page contains a few commonly occurring questions.
keadm init failed to download release¶
If you have issue about connection to github, please follow below guide with proxy before do setup, take
v1.4.0 as example:
download release pkgs from release page
download crds yamls matches the release version you downloaded, links as below:
put them under
$ tree -L 3 . ├── crds │ ├── devices │ │ ├── devices_v1alpha2_devicemodel.yaml │ │ └── devices_v1alpha2_device.yaml │ └── reliablesyncs │ ├── cluster_objectsync_v1alpha1.yaml │ └── objectsync_v1alpha1.yaml └── kubeedge-v1.4.0-linux-amd64.tar.gz 3 directories, 5 files
Then you can do setup without any network issue,
keadm would detect them and not download again(make sure you specify
v1.4.0 with option
Container keeps pending/ terminating¶
Check the output of
kubectl get nodes, whether the node is running healthy. Note that nodes in unreachable, offline status cannot complete graceful/soft pod deletion until they come back to normal.
Check the output of
kubectl describe pod <your-pod>, whether the pod is scheduled successfully.
edgecorelogs for any errors.
Check the architecture of the node running
edgecoreand make sure that container image you are trying to run is of the same architecture. For example, if you are running
edgecoreon Raspberry Pi 4, which is of
arm64v8architecture, the nginx image to be executed would be
arm64v8/nginxfrom the docker hub.
Also, check that the
podSandboxImageis correctly set as defined in Modification in edgecore.yaml.
If all of the above is correctly set, login manually to your edge node and run your docker image manually by
docker run <your-container-image>
If the docker container image is not pulled from the docker hub, please check that there is enough space on the edge node.
Where do we find cloudcore/edgecore logs¶
This depends on the how cloudcore/ edgecore has been executed.
systemdwas used to start the cloudcore/ edgecore? then use
journalctl --unit <name of the service probably edgecore.service>to view the logs.
nohupwas used to start the cloudcore/ edgecore, either a path would have been added where the log is located, Otherwise, if the log file wasn’t provided, the logs would be written to stdout.
Where do we find the pod logs¶
Connect to the edge node and then either
- use the log file located in
- use commands like
docker logs <container id>
kubectl logs is not yet supported by KubeEdge.
