kf logs

Name

kf logs - Show logs for an App.

Synopsis

kf logs APP_NAME [flags]

Description

Logs are streamed from the Kubernetes log endpoint for each running App instance.

If App instances change or the connection to Kubernetes times out the log stream may show duplicate logs.

Logs are retained for App instances as space permits on the cluster, but will be deleted if space is low or past their retention date. Cloud Logging is a more reliable mechanism to access historical logs.

If you need logs for a particular instance use the kubectl CLI.

Examples

# Follow/tail the log stream
kf logs myapp

# Follow/tail the log stream with 20 lines of context
kf logs myapp -n 20

# Get recent logs from the App
kf logs myapp --recent

# Get the most recent 200 lines of logs from the App
kf logs myapp --recent -n 200

# Get the logs of Tasks running from the App
kf logs myapp --task
