  • Domain by GoDaddy, DNS by Route53; HOW TO Enable DNSSEC in your domains

    Introduction The Domain Name System Security Extensions (DNSSEC) is a set of specifications that extend the DNS protocol by adding cryptographic authentication for responses received from authoritative DNS servers. Its goal is to defend against techniques that hackers use to direct computers to rogue websites and servers. DNSSEC adds two important features to the DNS protocol: Data origin authentication allows a resolver to cryptographically verify that the data it received came from the zone where it believes the data originated. Data integrity protection lets the resolver know that the data hasn't been modified in transit since it was originally signed by the zone owner with the zone's private key. How do DNS resolvers know how to trust in the DNSSEC keys? A zone's public key is signed, just like the other data in the zone. However, the public key is not signed by the zone's private key, but by the parent zone's private key. Every zone's public key is signed by its  parent zone, except for the root zone: it has no parent to sign its key. Therefore, the root zone's public key is an important starting point for validating DNS data. If a resolver trusts the root zone's public key, it can trust the public keys of top-level zones signed by the root's private key, such as the public key for the org zone. And because the resolver can trust the public key for the org zone, it can trust public keys signed by their respective private key, such as the public key for icann.org. (In actual practice, the parent zone doesn't sign the child zone's key directly--the actual mechanism is more complicated--but the effect is the same as if the parent had signed the child's key.) The sequence of cryptographic key signing is called a chain of trust. How much does it cost to enable DNSSEC in AWS? Amazon Route 53 does not charge you to enable DNSSEC signing on your public hosted zones or to enable DNSSEC validation for Amazon Route 53 Resolver. However, when you enable DNSSEC signing on your public hosted zones, you incur AWS Key Management Service (KMS) charges for storing the private key and using the instances of the key to sign your zones. For more information about KMS charges, see the AWS KMS pricing page. Note that you can choose to use a single customer-managed AWS KMS key that is stored in KMS across multiple public hosted zones. How do we enable DNSSEC? Let’s consider we have a root zone in AWS, where we host all our domains, but it still depends on GoDaddy, for example, how could we enable DNSSEC in this case? First of all, we need to take some considerations: DNS propagation can take anywhere from a few minutes to 24 hours, depending on the geographical location of the user, the type of DNS record being updated, and the TTL (time to live) value set for the record. During this time, the updated DNS information may not be available to all users and systems immediately. Pre-requisites To configure DNSSEC for a domain, your domain, and DNS service provider must meet the following prerequisites: The registry for the top-level domain (TLD) must support DNSSEC. To determine whether the registry for your TLD supports DNSSEC, see Domains that you can register with Amazon Route 53. The DNS service provider for the domain must support DNSSEC. You must configure DNSSEC with the DNS service provider for your domain before you add public keys for the domain to Route 53. The number of public keys that you can add to a domain depends on the TLD for the domain: .com and .net domains – up to thirteen keys All other domains – up to four keys Before start recommendations Lowering the zone's maximum TTL will help reduce the wait time between enabling signing and the insertion of the Delegation Signer (DS) record. Lowering the zone's maximum TTL to 1 hour (3600 seconds) allows us to roll back after only an hour if any resolver has problems caching signed records. Lower the SOA TTL and SOA minimum field. The SOA minimum field is the last field in the SOA record data. The SOA TTL and SOA minimum field determines how long resolvers remember negative answers. After you enable signing, Route 53 name servers start returning NSEC records for negative answers. The NSEC contains information that resolvers might use to synthesize a negative answer. If you have to roll back because the NSEC information caused a resolver to assume a negative answer for a name, then you only have to wait for the maximum of the SOA TTL and SOA minimum field for the resolver to stop the assumption. Make sure the TTL and SOA minimum field changes are effective.Use GetChange to ensure that your changes have been propagated to all Route 53 DNS servers. Enabling DNSSEC signing at Route 53 Click on Enable DNSSEC signing at the DNSSEC signing tab, in the hosted zone console. Choose to create a customer-managed CMK Create KSK and enable signing After enabling DNSSEC, click on View Information to Create a DS Record. Check on Establish a chain of trust -> Another Domain Registrar section. Go Daddy configuration steps Go to Domain Portfolio -> Domain Settings for your domain and select DNSSEC. Create a new DS record with the following information: Key Tag: Key Tag in AWS Algorithm: Signing Algorithm Type in AWS Digest Type: Digest Algorithm Type in AWS Digest: Digest in AWS Testing To check if the new configuration is properly set up and the DNS is answering as expected: dig dnskey +dnssec We should receive two DNSKEYs (one for ZSK and another for KSK) and a signed resource record (RRSIG), confirming that the DNS servers are successfully using DNSSEC. To check the chain of trust with the TLD: dig com NS +short The answer should retrieve the TLD server name dig DS +short To make sure we get the DS record for the journeytrack domain from TLD. You should get the DS record shown in the DNSSEC recommendations to create the record. dig A +dnssec To check if the resource record is set with signatures. Answers must return A and RRSIG info. dig DNSKEY journeytrack.io +short To validate the DS public key Rollback If any problem or issue arises during the implementation, DNSSEC can be easily reverted: Disable DNSSEC from go Daddy and Route53 Restore SOA changes Undo NS TTL changes Lourdes Dorado Cloud Engineer Teracloud

  • How to configure ArgoCD OIDC with Google Workspace in 5 simple steps

    There are different ways to handle authentication in ArgoCD, but indeed using the admin password is not secure enough. For this reason, we’ll learn how to configure your ArgoCD to integrate with Google Workspace for Login. In this TeraTip we’ll cover one of the approaches for authentication, using ‌groups from Google Workspace. Before you get started… In order to get the SSO working you need to have the SSL and URL for your server already configured, otherwise, you’ll get errors during the authentication. Step #1: Create the OAuth Screen First, you create a project with any name you want and configure the OAuth screen as follows: In the Authorized domains section, it is important to configure the domain for the email your users have, in this case, we add the domain for our organization. Finally, on the Scopes tab select the userinfo.profile and the openid scopes. Those are the scopes ArgoCD needs for the log in. Step #2: Create the OAuth Client ID On the Credentials tab, click on + Create Credentials and OAuth client ID. Then select on Application type, Web Application, and configure the JavaScript origins and redirect URIs. In the Authorized JavaScripts origins section, configure the root URL for your ArgoCD. Then in Authorized redirect URIs copy this URL but append the /api/dex/callback path. Then click on create and save your Client ID and Client Secret for later. Step #3: Configure the Service Account on Google Workspace Now create the Service Account and configure the Domain Wide delegation, in order to make ArgoCD able to read the groups. On the Service Account section of the Google Console we click on + CREATE SERVICE ACCOUNT. You only need to enter a name for the service account and enter any name you like. Enter ‌your service account, go to the Keys tab, click on Add Key, and select JSON as format. Save the keys, we will use them later for configuring the OIDC. Step #4: Set up Domain Wide delegation and enabling Admin SDK To close with the Google configuration you’ll now have to configure Domain Wide delegation and enable the Admin SDK. First head to the Google Cloud Admin console, and then go to Security, Access and data control, API controls, and, lastly, then click on manage domain wide delegation. Click on Add Client, and then on Client ID paste the Client ID of your service account, and on the scopes section paste this: https://www.googleapis.com/auth/admin.directory.group.readonly Finally, head to https://console.cloud.google.com/apis/library/admin.googleapis.com and enable the Admin SDK for your project. Step #5: Configure ArgoCD To configure the OIDC create two secrets on your cluster, one for the Client Secret we got on Step 2 and one for the JSON we got on Step 3. For the client secret: For the JSON: Now if you are using the ArgoCD Helm Chart, you can use the following values, tested on version 5.27.1: Now you have your ArgoCD configured with Google SSO!

  • Get your first job in IT with AWS Certifications

    Could you land your first job with just AWS certifications and no experience at all? Almost… but not exactly. The following explores how helpful an AWS Certification is when landing your first job in IT, and why it’s so important not to fall for the “only certifications will guarantee you a job” trap. An AWS certification is a professional credential offered by Amazon Web Services (AWS) that validates an individual's knowledge and expertise in various AWS cloud computing services and technologies. These certifications are designed to demonstrate a person's proficiency in using AWS services and solutions to design, deploy, and manage cloud-based applications and infrastructure. It's proof that you know how to use Amazon Web Services and understand cloud concepts. That said, one could deduce that obtaining these certifications is a really good way to demonstrate your knowledge, and stand out among your peers. But is that all? AWS Partners would disagree. What are AWS Partners? AWS partners are organizations that collaborate with AWS to offer a wide range of services, solutions, and expertise related to AWS cloud computing. AWS partners come in various forms and play critical roles in helping businesses leverage AWS services to meet their unique needs. In other words, partners are companies that help AWS implement their services. You have different partner tiers: AWS Select Tier Services Partners AWS Advanced Tier Services Partners AWS Premier Tier Services Partners The equation is really simple: The more qualified you are, the more clients you get. The more clients you get, the more money the company makes. Therefore it’s in an AWS Partner's best interest to become more specialized, and that's where certifications come into play. To become a specialized partner among other things, you need technical certified individuals. As you can see, being an AWS Premier Partner, companies require 25 individuals be certified. And that’s why having a certification becomes really valuable, even more if it’s a Professional or Specialty one. Other Benefits There are even badges for how many certifications a partner has, which give more credibility to the provided service. There are other benefits as a partner such as being eligible to earn credits for the client. That means, receiving hundreds or even thousands in financing through credits for you to offer your clients. Final thoughts To sum up, if you don’t have any experience at all, having an AWS Certification will really help you to obtain interviews and if you combine the knowledge acquired with real case scenarios you’ll be closer to landing your dream job. If on the other hand you only obtain the certification yet don’t have any practical abilities or field work, the certificate won’t really help at all. Strategize. Find companies that are AWS Partners and apply to them. They’re looking for technical individuals and you’re looking for real case scenarios. It’s in real-life Cloud challenges where you actually get to apply your knowledge and ultimately gain the confidence and proof you’ll need to continue developing your professional skills.

  • How to integrate Prometheus in an EKS Cluster as a Data Source in AWS Managed Grafana

    Whether you're an experienced DevOps engineer or just starting your cloud journey, this article will equip you with the knowledge and tools needed to effectively monitor and optimize your EKS environment. Objective Configure and use Prometheus to collect metrics on an Amazon EKS cluster and view those metrics in AWS Managed Grafana (AMG). Provide usage instructions and an estimate of the costs of connecting Prometheus metrics as an AMG data source. Let’s assume that fluentbit is already configured on the EKS cluster. Step #1: Prometheus Configuration Ensure Prometheus is installed and running in your Amazon EKS cluster. You can install via Terraform using helm chart. Verify that Prometheus is successfully collecting metrics from your cluster nodes and applications. Step #2: Configure the data source in Grafana Now you’ll need to configure the data source in Grafana. (Here the created LoadBalancer will serve as a reference) Make sure the AWS Route53 console is open, and a private Hosted Zone named "monitoring.domainname" is created. Inside this Hosted Zone, create an Alias record pointing to the LoadBalancer previously mentioned. This data will be used to configure the Prometheus service as the data source in AMG. AWS Managed Grafana Configuration Provision an instance of AWS Managed Grafana. Access the AWS Managed Grafana console and obtain the URL to access the Grafana instance. Ensure you have the necessary permissions to manage data sources in AWS Managed Grafana. Configure Prometheus as a Data Source in AWS Managed Grafana: Access the AWS Managed Grafana console using the URL obtained in step 2. Navigate to the "Configuration" section and select "Data sources". Click on "Add data source" and choose "Prometheus" as the data source type. Complete the required fields, including the Prometheus endpoint URL and authentication credentials if applicable, or a Workspace IAM Role. Save the data source configuration. Visualizing Metrics in Grafana: Identify the KPIs needed to visualize in the dashboard Create dashboards in Grafana to visualize the metrics collected by Prometheus. Utilize Grafana's query and visualization options to create customized visualizations of your metrics. Explore different panel types such as graphs, tables, and text panels to present the information in a clear and understandable manner. Step #3: Estimate costs To estimate the costs associated with integrating Prometheus as a data source in AWS Managed Grafana, consider the following: AWS Managed Grafana Costs: Refer to the AWS documentation to understand the details and pricing associated with AWS Managed Grafana. According to the following documentation, the price is per license, either editor or user. The editor can create and edit both the workspace and the metric display and the user can only view the panels and metrics previously configured by the editor. (https://aws.amazon.com/es/grafana/pricing/). Today, the editor license cost $9 and the user license cost $5 Storage Costs: If AWS Managed Grafana utilizes additional storage to store metrics collected by Prometheus, refer to the AWS documentation for information on pricing and available storage options. Remember that costs may vary depending on your specific configuration and the AWS region where your AWS Managed Grafana instance is located. Consult the documentation and updated pricing details for accurate cost estimation. Final thoughts In conclusion, this is a very interesting and easy-to-implement alternative to replace solutions in clusters that have a large number of running pods. This scenario generates an even larger number of metrics, and that's where this processing-based and licensed solution becomes much more cost-effective compared to a metric-based pricing model.

  • How to use a secondary CIDR in EKS

    In this Teratip, we’ll deep dive into the realm of secondary CIDR blocks in AWS EKS and explore how they can empower you to enhance your cluster's flexibility and scalability. We’ll uncover the benefits of leveraging secondary CIDR blocks and walk you through the process of configuring them. Introduction As you expand your applications and services, you may face scenarios where the primary CIDR block assigned to your EKS cluster becomes insufficient. Perhaps you're introducing additional microservices, deploying multiple VPC peering connections, or integrating with legacy systems that have their own IP address requirements. These situations call for a solution that allows you to allocate more IP addresses to your cluster without sacrificing stability or network performance. Secondary CIDR blocks provide an elegant solution by enabling you to attach additional IP address ranges to your existing VPC, thereby expanding the available address space for your EKS cluster. Throughout this post, we’ll go over the step-by-step process of adding secondary CIDR blocks to your AWS EKS cluster. Create the EKS cluster For this demonstration, I created a simple EKS cluster with only one node and deployed the famous game 2048 which can be accessed through an Internet-face Application Load Balancer. So, the EKS cluster and workload looks like this: And this is the VPC where the cluster is located: As you can see, this VPC has the 10.0.0.0/16 IPv4 CIDR block assigned. Keeping this in consideration, all pods into the cluster will get an IP address within this range: Next, we will configure this same cluster to use a secondary CIDR block in the same VPC. In this way, almost all pods will get IP addresses from the new CIDR. Step by step process Step #1: Create the secondary CIDR within our VPC RESTRICTION: EKS supports additional IPv4 CIDR blocks in the 100.64.0.0/16 range. It’s possible to add a second CIDR to the current VPC, and of course create subnets within this VPC using the new range. I did it through Terraform but this can be done using the AWS Console as well. The code that I used to create the VPC is the following: module "vpc" { source = "terraform-aws-modules/vpc/aws" version = "3.19.0" name = "teratip-eks-2cidr-vpc" cidr = "10.0.0.0/16" secondary_cidr_blocks = ["100.64.0.0/16"] azs = slice(data.aws_availability_zones.available.names, 0, 2) private_subnets = ["10.0.1.0/24", "10.0.2.0/24", "100.64.1.0/24", "100.64.2.0/24"] public_subnets = ["10.0.4.0/24", "10.0.5.0/24"] enable_nat_gateway = true single_nat_gateway = true enable_dns_hostnames = true public_subnet_tags = { "kubernetes.io/cluster/${local.cluster_name}" = "shared" "kubernetes.io/role/elb" = 1 } private_subnet_tags = { "kubernetes.io/cluster/${local.cluster_name}" = "shared" "kubernetes.io/role/internal-elb" = 1 } } Take a look to the line secondary_cidr_blocks = ["100.64.0.0/16"] and the private subnets (the last two) created into this CIDR: private_subnets = ["10.0.1.0/24", "10.0.2.0/24", "100.64.1.0/24", "100.64.2.0/24"] The obtained VPC looks like this: Step #2: Configure the CNI DEFINITION: CNI (Container Network Interface), concerns itself with network connectivity of containers and removing allocated resources when the container is deleted. In order to use a secondary CIDR into the cluster it’s needed to configure some environment variables in the CNI daemonset configuration, by running the following commands: 1. To turn on custom network configuration for the CNI plugin, run the following command: kubectl set env ds aws-node-n kube-system AWS_VPC_K8S_CNI_CUSTOM_NETWORK_CFG=true 2. To add the ENIConfig label for identifying your worker nodes, run the following command: kubectl set env daemonset aws-node-n kube-system ENI_CONFIG_LABEL_DEF=topology.kubernetes.io/zone 3. Enable the parameter to assign prefixes to network interfaces for the Amazon VPC CNI DaemonSet. kubectl set env daemonset aws-node-n kube-system ENABLE_PREFIX_DELEGATION=true Terminate worker nodes so that Autoscaling launches newer nodes that come bootstrapped with custom network config. Step #3: Create the ENIconfig resources for the new subnets As next step, we will add custom resources to ENIConfig custom resource definition (CRD). In this case, we will store VPC Subnet and SecurityGroup configuration information in these CRDs so that Worker nodes can access them to configure VPC CNI plugin. Create custom resources for each subnet by replacing Subnet and SecurityGroup IDs. Since we created two secondary subnets, we need to create three custom resources. --- apiVersion: crd.k8s.amazonaws.com/v1alpha1 kind: ENIConfig metadata: name: us-east-2a spec: securityGroups: -sg-087d0a0ece9800b00 subnet: subnet-0fabe93c6f43f492b --- apiVersion: crd.k8s.amazonaws.com/v1alpha1 kind: ENIConfig metadata: name: us-east-2b spec: securityGroups: -sg-087d0a0ece9800b00 subnet: subnet-0484194486fad2ce3 Note: The ENIConfig name must match the Availability Zone of your subnets. You can get the Cluster security group included in the ENIConfigs in the EKS Console or by running the following command: aws eks describe-cluster --name $cluster_name --querycluster.resourcesVpcConfig.clusterSecurityGroupId --output text Once ENIConfigs YAML is created apply them: kubectl apply -f Check the new network configuration Finally, all the pods running into your worker nodes should have IP addresses within the secondary CIDR. As you can see in the screenshot below, the service is still working as it should be: Also, notice that the EC2 worker node has now an ENI (Elastic Network Interface) with and IP address within the secondary CIDR: Configure max-pods per node Enabling a custom network removes an available network interface from each node that uses it and the primary network interface for the node is not used for pod placement when a custom network is enabled. In this case, you must update max-pods: To do this step I used Terraform to update the node group increasing the max-pods parameter: Following is the IaC for the EKS cluster: module "eks" { source = "terraform-aws-modules/eks/aws" version = "19.5.1" cluster_name = local.cluster_name cluster_version = "1.24" vpc_id = module.vpc.vpc_id subnet_ids = [module.vpc.private_subnets[0], module.vpc.private_subnets[1]] cluster_endpoint_public_access = true eks_managed_node_group_defaults = { ami_type = "AL2_x86_64" } eks_managed_node_groups = { one = { name = "node-group-1" instance_types = ["t3.small"] min_size = 1 max_size = 1 desired_size = 1 bootstrap_extra_args = "--container-runtime containerd --kubelet-extra-args '--max-pods=110'" pre_bootstrap_user_data = <<-EOT export CONTAINER_RUNTIME="containerd" export USE_MAX_PODS=false EOT } } } In the example I set up max-pods = 110, which is too much for this type of EC2 instance but is a hard limit. This node will allocate as many pods as its resources allow. If you’re interested in learning more about how to Increase the amount of available IP addresses for your nodes, here is an interesting guide from AWS that you can read. Just in case… If for some reason, something goes wrong and your pods aren’t getting IP addresses, you can easily rollback your changes by running the following command and launching new nodes: kubectl set env ds aws-node-n kube-system AWS_VPC_K8S_CNI_CUSTOM_NETWORK_CFG=false After running the command, the whole cluster will come back using the primary CIDR again. Final Thoughts By diligently following the step-by-step instructions provided in this guide, you have acquired the knowledge to effectively set up and supervise secondary CIDR blocks, tailoring your network to harmonize precisely with the needs of your applications. This newfound adaptability not only simplifies the allocation of resources but also grants you the capability to seamlessly adjust your infrastructure in response to evolving requirements.
