I'm trying to assign a service on hosts that includes the name of the service in their vars.
service.conf -
apply Service "check_service1"{
check_command = this.name
assign where this.name in host.vars.service_list
}
hosts.conf -
object Host "test" {
display_name = "Test Site"
check_command = "dummy"
vars.service_list = ["check_service1"]
}
after restarting i tried to execute icinga2 object list --type service but it returns nothing.
in addition, when trying assign expression like this - "check_service1" in host.vars.service_list it works but i don't want to use it because i want it to be in a template.
thanks to anyone answering!

I have written some Terraform code to create some servers. For AMI I was using the Terraform data module to get the latest Ubuntu 16.04 image ID and assign it to the EC2 instances.
Recently I wanted to add another EC2 instance to this environment, however when I run terraform plan I can see that Terraform is trying to delete the existing EC2 instance and recreate them. The reason being that a new Ubuntu image has been released and it is trying to delete the old instance and create new ones with the new AMI ID.
Is there any chance I can address this issue as I don't want to accidentally delete our production servers?
data "aws_ami" "ubuntu" {
most_recent = true
filter {
name = "name"
values = ["ubuntu/images/hvm-ssd/ubuntu-xenial-16.04-amd64-server-*"]
}
filter {
name = "virtualization-type"
values = ["hvm"]
}
}
module "jenkins" {
source = "terraform-aws-modules/ec2-instance/aws"
name = "Jenkins"
instance_count = 1
ami = "${data.aws_ami.ubuntu.id}"
instance_type = "t2.small"
associate_public_ip_address = true
disable_api_termination = true
key_name = "${aws_key_pair.ssh_key.key_name}"
monitoring = false
vpc_security_group_ids = "${module.jenkins_http_sg.this_security_group_id}", "${module.jenkins_https_sg.this_security_group_id}", "${module.ssh_sg.this_security_group_id}"]
subnet_id = "${module.vpc.public_subnets[0]}"
iam_instance_profile = "${aws_iam_instance_profile.update-dns-profile.name}"
tags = {
Terraform = "true"
}
}
While the answer above helps, I solved the problem by adding the following to the aws_instance resource.
lifecycle {
ignore_changes = ["ami"]
}
Please note if you are using the AWS module like I am using, you will have to enter this code to the main.tf file in .terraform/modules/.
Terraform is doing exactly as you asked it to do. Each time it runs it looks for the most recent AMI with a name beginning with ubuntu/images/hvm-ssd/ubuntu-xenial-16.04-amd64-server-* and then passes that AMI ID to the aws_instance resource. As it's not possibly to modify the image ID of an instance, Terraform correctly determines it must destroy the old instances and rebuild them from the new AMI.
If you want to specify a specific AMI then you should either make the data source only return a single AMI (eg by specifying the date stamp in the name filter) or you should hardcode the AMI ID you want to use.
data "aws_ami" "ubuntu" {
most_recent = true
owners = ["099720109477"] # Canonical
filter {
name = "name"
values = ["ubuntu/images/hvm-ssd/ubuntu-xenial-16.04-amd64-server-20190403"]
}
filter {
name = "virtualization-type"
values = ["hvm"]
}
}
or:
variable "ami" {
default = "ami-0727f3c2d4b0226d5"
}
If you were to remove the most_recent = true parameter then instead your data source would find multiple images that match those criteria and then fail as the aws_ami data source can only return a single AMI:
NOTE: If more or less than a single match is returned by the search, Terraform will fail. Ensure that your search is specific enough to return a single AMI ID only, or use most_recent to choose the most recent one. If you want to match multiple AMIs, use the aws_ami_ids data source instead.
Also note that I added the owners field to your data source. This is now required since version 2.0.0 because otherwise this was very insecure as your data source could return any public image that uses that naming scheme.
I am beginning to use the sample IBM-IOT C# sample code as per
https://github.com/ibm-watson-iot/iot-csharp/blob/master/docs/Gateway.rst
however I get "An invalid IP address was specified." thrown when the gateway constructor is called using the org id.
I'm using an orgid of 'p3wg4w' (set in config and accessed as a string property Globals.WatsonOrgID" )
my code is
private static void InitGatewayClient()
{
if (gw == null)
{
gw = new GatewayClient(Globals.WatsonOrgID,
Globals.WatsonGatewayDeviceType,
Globals.WatsonGatewayDeviceID,
Globals.WatsonAuthMethod,
Globals.WatsonToken);
gw.commandCallback += processCommand;
gw.errorCallback += processError;
gw.connect();
Console.WriteLine("Gateway connected");
Console.WriteLine("publishing gateway events..");
}
}
Has anyone seen this before ?
check if you can access or if you can:
telnet p3wg4w.messaging.internetofthings.ibmcloud.com 8883
The libraries aren't using any IP to create the connection, it is using the below vars
public static string DOMAIN = ".messaging.internetofthings.ibmcloud.com";
public static int MQTTS_PORT = 8883;
I can only think that your firewall is blocking the connection
I've used the below sample and worked just fine for me:
https://github.com/ibm-watson-iot/iot-csharp/blob/master/sample/Gateway/SampleGateway.cs
I have been working on a skill where I am using Login With Amazon account linking so I can grab the user email address and name to use in my skill. I am doing something similar to the scoreKeeper sample, using the eventHandlers.js and the storage.js for saving items to a database. In the eventHandlers.onLaunch I am successfully getting the profile name and email address from Amazon and I save it to the session.attributes like this:
var profile = JSON.parse(body);
speechOutput="Hello, " + profile.name.split(" ")[0] + ".";
var sessionAttributes = {};
sessionAttributes = { name: profile.name, email: profile.email };
session.attributes = sessionAttributes;
console.log("Name in session:", session.attributes.name);
The console log shows the name so I know it is being saved in the session.attributes, but when I try to access the session.attributes in my storage.js or intentHandlers.js, it shows it as being empty. What am I missing? Thanks in advance. This has been driving me crazy.
I got this working by adding session to the callback of the response.ask function, like this:
ask: function (speechOutput, repromptSpeech, _session) {
this._context.succeed(buildSpeechletResponse({
session: _session,
output: speechOutput,
reprompt: repromptSpeech,
shouldEndSession: false
}));
},
It had session: this._session for saving the session, but that didn't seem to be working for me. Passing it as a variable did.
Let's say you want to obtain city name from the user and be able to access that value later in the Alexa session:
1) Pre-define your key/value pairs in the JSON response:
def build_response(session_attributes, speechlet_response):
return {
'version': '1.0',
'sessionAttributes': {
"session_attributes": {
'NameOfCity': city_name,
}
},
'response': speechlet_response
}
2) In global scope, declare the variable as an empty string:
city_name = "",
3) Whenever you update that variable within a function, make sure you reference that variable as global. For example:
def set_city_name_in_session(intent, session):
card_title = intent['name']
session_attributes = {}
should_end_session = False
if 'CityIntent' in intent['slots']:
global city_name
city_name = intent['slots']['CityIntent']['value']
4) When creating a function that needs to access this variable, pass the global variable as an argument into the function then, within the function, expose all session key/pair values like so:
def access_variables(intent, session, city_name):
card_title = intent['name']
session_attributes = {}
should_end_session = False
exposed_attributes = session['attributes']['session_attributes']
city_name_attribute_value = exposed_attributes.get('NameOfCity')
if (some_kind_of_condition):
do something awesome with city_name_attribute_value
To test, enter sample utterances into Service Simulator then check if values are persisting in your Lambda JSON response.
I'm trying to use the attributes of an EC2 instance as a variable, but it keeps failing or otherwise not working. As you can see below, I want to insert the private IP of the instance into a config file that will get copied to the instance. The remote-exec script will then move the file into place (/etc/vault.d/server-config.json)
instances.tf
resource "template_file" "tpl-vault-server-config" {
template = "${file("${path.module}/templates/files/vault-server-config.json.tpl")}"
vars {
aws_private_ip = "${aws_instance.ec2-consul-server.private_ip}"
}
}
provisioner "file" {
source = "${template_file.tpl-vault-server-config.rendered}"
destination = "/tmp/vault-server-config.json"
}
vault-server-config.json.tpl
backend "consul" {
address = "127.0.0.1:8500"
path = "vault"
tls_enable = 1
tls_ca_file = "/etc/consul.d/ssl/ca.cert"
tls_cert_file = "/etc/consul.d/ssl/consul.cert"
tls_key_file = "/etc/consul.d/ssl/consul.key"
}
listener "tcp" {
address = "${aws_private_ip}:8200"
tls_cert_file = "/etc/consul.d/ssl/consul.cert"
tls_key_file = "/etc/consul.d/ssl/consul.key"
}
The error on terraform plan is:
* aws_instance.ec2-consul-server: missing dependency: template_file.tpl-vault-server-config
Questions:
Am I taking the wrong approach?
Am I missing something basic?
How do you get an instance's attributes into a file?
Thanks in advance.
I realized that I was defining the template_file resource within the current resource and this was part of the problem. When I fixed that, things worked much easier.
Is there any way to get all the Microsoft-Azure service bus queues name using crated namespace endpoint.
Using namespaceManager we can get all the queue's name.
string connectionString = CloudConfigurationManager.GetSetting("Microsoft.ServiceBus.ConnectionString");
var namespaceManager = NamespaceManager.CreateFromConnectionString(connectionString);
//Getting all available queue's.
IEnumerable<QueueDescription> queueList = namespaceManager.GetQueues();
foreach (QueueDescription qd in queueList)
{
Console.WriteLine("Queue name {0}", qd.Path, qd.MessageCount);
}
