kubectl¶

get kubernetes event log¶

...sorted by timestamp

kubectl get events --sort-by=.metadata.creationTimestamp

tail logs¶

this will read the last 100 log entries and also keep following the log for new entries

kubectl logs -f --tail=100 <pod-name>

download kubectl for arm architecture, like an raspberry pi¶

I don't know why they make it so hard, but here you go:

curl -LO "https://dl.k8s.io/release/$(curl -L -s https://dl.k8s.io/release/stable.txt)/bin/linux/arm/kubectl"

run cronjob manually¶

get list of cron jobs:

kubectl get cronjob
# gickup   0 4 * * * [...]

run a manual job:

kubectl create job --from=cronjob/gickup gickup-run-manual

you might want to delete the job afterwards:

kubectl delete job gickup-run-manual

run one-off pod¶

example, run the minio/mc container and override the command to end up in a shell instead of the default mc entrypoint

kubectl run -i --tty mc --image=minio/mc --command /bin/sh

run pod with registry secrets¶

update / replace registry-secret-name and specify your image after --image

kubectl run -i --tty my-container --image=ghcr.io/example/private-image:latest --command /bin/sh --overrides='{ "spec": { "imagePullSecrets": [{"name": "registry-secret-name"}] } }'

port forwarding¶

you may want to omit --address=0.0.0.0

kubectl port-forward pod-name-here --address=0.0.0.0 8384:8384

get a random local port:

kubectl port-forward pod-name-here --address=0.0.0.0 :8384
