Overview

Note:

When making an API call, you may pass HealthCheck data as a hash:

{
  command: ["String"], # required
  interval: 1,
  timeout: 1,
  retries: 1,
  start_period: 1,
}

An object representing a container health check. Health check parameters that are specified in a container definition override any Docker health checks that exist in the container image (such as those specified in a parent image or from the image’s Dockerfile).

Instance Attribute Summary

• #command ⇒ Array<String>

  A string array representing the command that the container runs to determine if it is healthy.

• #interval ⇒ Integer

  The time period in seconds between each health check execution.

• #retries ⇒ Integer

  The number of times to retry a failed health check before the container is considered unhealthy.

• #start_period ⇒ Integer

  The optional grace period within which to provide containers time to bootstrap before failed health checks count towards the maximum number of retries.

• #timeout ⇒ Integer

  The time period in seconds to wait for a health check to succeed before it is considered a failure.

Instance Attribute Details

#command ⇒ Array<String>

A string array representing the command that the container runs to determine if it is healthy. The string array must start with ‘CMD` to execute the command arguments directly, or `CMD-SHELL` to run the command with the container’s default shell. For example:

‘[ “CMD-SHELL”, “curl -f localhost/ || exit 1” ]`

An exit code of 0 indicates success, and non-zero exit code indicates failure. For more information, see ‘HealthCheck` in the

section of the [Docker Remote API].

class HealthCheck < Struct.new(
  :command,
  :interval,
  :timeout,
  :retries,
  :start_period)
  include Aws::Structure
end

#interval ⇒ Integer

The time period in seconds between each health check execution. You may specify between 5 and 300 seconds. The default value is 30 seconds.

Returns:

• (Integer)

# File 'lib/aws-sdk-ecs/types.rb', line 2344

class HealthCheck < Struct.new(
  :command,
  :interval,
  :timeout,
  :retries,
  :start_period)
  include Aws::Structure
end

#retries ⇒ Integer

The number of times to retry a failed health check before the container is considered unhealthy. You may specify between 1 and 10 retries. The default value is 3 retries.

Returns:

• (Integer)

# File 'lib/aws-sdk-ecs/types.rb', line 2344

class HealthCheck < Struct.new(
  :command,
  :interval,
  :timeout,
  :retries,
  :start_period)
  include Aws::Structure
end

#start_period ⇒ Integer

The optional grace period within which to provide containers time to bootstrap before failed health checks count towards the maximum number of retries. You may specify between 0 and 300 seconds. The ‘startPeriod` is disabled by default.

<note markdown=“1”> If a health check succeeds within the ‘startPeriod`, then the container is considered healthy and any subsequent failures count toward the maximum number of retries.

#timeout ⇒ Integer

The time period in seconds to wait for a health check to succeed before it is considered a failure. You may specify between 2 and 60 seconds. The default value is 5 seconds.
