Options for applying CloudFormation init to an instance or instance group.

  • Method Details

    • getConfigSets

      @Stability(Stable) @Nullable default List<String> getConfigSets()
      ConfigSet to activate.

      Default: ['default']

    • getEmbedFingerprint

      @Stability(Stable) @Nullable default Boolean getEmbedFingerprint()
      Force instance replacement by embedding a config fingerprint.

      If true (the default), a hash of the config will be embedded into the UserData, so that if the config changes, the UserData changes and instances will be replaced (given an UpdatePolicy has been configured on the AutoScalingGroup).

      If false, no such hash will be embedded, and if the CloudFormation Init config changes nothing will happen to the running instances. If a config update introduces errors, you will not notice until after the CloudFormation deployment successfully finishes and the next instance fails to launch.

      Default: true

    • getIgnoreFailures

      @Stability(Stable) @Nullable default Boolean getIgnoreFailures()
      Don't fail the instance creation when cfn-init fails.

      You can use this to prevent CloudFormation from rolling back when instances fail to start up, to help in debugging.

      Default: false

    • getIncludeRole

      @Stability(Stable) @Nullable default Boolean getIncludeRole()
      Include --role argument when running cfn-init and cfn-signal commands.

      This will be the IAM instance profile attached to the EC2 instance

      Default: false

    • getIncludeUrl

      @Stability(Stable) @Nullable default Boolean getIncludeUrl()
      Include --url argument when running cfn-init and cfn-signal commands.

      This will be the cloudformation endpoint in the deployed region e.g. https://cloudformation.us-east-1.amazonaws.com

      Default: false

    • getPrintLog

      @Stability(Stable) @Nullable default Boolean getPrintLog()
      Print the results of running cfn-init to the Instance System Log.

      By default, the output of running cfn-init is written to a log file on the instance. Set this to true to print it to the System Log (visible from the EC2 Console), false to not print it.

      (Be aware that the system log is refreshed at certain points in time of the instance life cycle, and successful execution may not always show up).

      Default: true

    • builder

      @Stability(Stable) static ApplyCloudFormationInitOptions.Builder builder()
      Returns:
      a ApplyCloudFormationInitOptions.Builder of ApplyCloudFormationInitOptions
