  • Print the Logs of a Container in a cluster

Summarizing Resources


Debugging Workloads by printing out the Logs of containers in a cluster.

Print the logs for a Pod running a single Container

kubectl logs echo-c6bc8ccff-nnj52

Crash Looping Containers

If a container is crash looping and you want to print its logs after it exits, use the -p flag to look at the logs from containers that have exited. e.g. kubectl logs -p -c ruby web-1

Print the logs for all Pods for a Workload

# Print logs from all containers matching label
kubectl logs -l app=nginx

Workloads Logs

Print all logs from all containers for a Workload by passing the Workload label selector to the -l flag. e.g. if your Workload label selector is app=nginx usie -l "app=nginx" to print logs for all the Pods from that Workload.

Follow Logs for a Container

Stream logs from a container.

# Follow logs from container
kubectl logs nginx-78f5d695bd-czm8z -f

Printing Logs for a Container that has exited

Print the logs for the previously running container. This is useful for printing containers that have crashed or are crash looping.

# Print logs from exited container
kubectl logs nginx-78f5d695bd-czm8z -p

Selecting a Container in a Pod

Print the logs from a specific container within a Pod. This is necessary for Pods running multiple containers.

# Print logs from the nginx container in the nginx-78f5d695bd-czm8z Pod
kubectl logs nginx-78f5d695bd-czm8z -c nginx

Printing Logs After a Time

Print the logs that occurred after an absolute time.

# Print logs since a date
kubectl logs nginx-78f5d695bd-czm8z --since-time=2018-11-01T15:00:00Z

Printing Logs Since a Time

Print the logs that are newer than a duration.


  • 0s: 0 seconds
  • 1m: 1 minute
  • 2h: 2 hours
# Print logs for the past hour
kubectl logs nginx-78f5d695bd-czm8z --since=1h

Include Timestamps

Include timestamps in the log lines

# Print logs with timestamps
kubectl logs -l app=echo --timestamps
