Probe

import "github.com/tilt-dev/tilt/pkg/apis/core/v1alpha1"

Probe describes a health check to be performed to determine whether it is alive or ready to receive traffic.

---

• exec (ExecAction)

  One and only one of the following should be specified. Exec specifies the action to take.

  ExecAction describes a “run in container” action.

  • exec.command ([]string)

    Command is the command line to execute inside the container, the working directory for the command is root (‘/’) in the container’s filesystem. The command is simply exec’d, it is not run inside a shell, so traditional shell instructions (‘|’, etc) won’t work. To use a shell, you need to explicitly call out to that shell. Exit status of 0 is treated as live/healthy and non-zero is unhealthy.

• failureThreshold (int32)

  Minimum consecutive failures for the probe to be considered failed after having succeeded. Defaults to 3. Minimum value is 1.

• httpGet (HTTPGetAction)

  HTTPGet specifies the http request to perform.

  HTTPGetAction describes an action based on HTTP Get requests.

  • httpGet.port (int32), required

    Name or number of the port to access on the container. Number must be in the range 1 to 65535.

  • httpGet.host (string)

    Host name to connect to, defaults to the pod IP. You probably want to set “Host” in httpHeaders instead.

  • httpGet.httpHeaders ([]HTTPHeader)

    Custom headers to set in the request. HTTP allows repeated headers.

    HTTPHeader describes a custom header to be used in HTTP probes

  • httpGet.httpHeaders.name (string), required

    The header field name

  • httpGet.httpHeaders.value (string), required

    The header field value

  • httpGet.path (string)

    Path to access on the HTTP server.

  • httpGet.scheme (string)

    Scheme to use for connecting to the host. Defaults to HTTP.

• initialDelaySeconds (int32)

  Number of seconds after the container has started before liveness probes are initiated. More info: https://kubernetes.io/docs/concepts/workloads/pods/pod-lifecycle#container-probes

• periodSeconds (int32)

  How often (in seconds) to perform the probe. Default to 10 seconds. Minimum value is 1.

• successThreshold (int32)

  Minimum consecutive successes for the probe to be considered successful after having failed. Defaults to 1. Must be 1 for liveness and startup. Minimum value is 1.

• tcpSocket (TCPSocketAction)

  TCPSocket specifies an action involving a TCP port. TCP hooks not yet supported

  TCPSocketAction describes an action based on opening a socket

  • tcpSocket.port (int32), required

    Number or name of the port to access on the container. Number must be in the range 1 to 65535.

  • tcpSocket.host (string)

    Optional: Host name to connect to, defaults to the pod IP.

• timeoutSeconds (int32)

  Number of seconds after which the probe times out. Defaults to 1 second. Minimum value is 1. More info: https://kubernetes.io/docs/concepts/workloads/pods/pod-lifecycle#container-probes
