Lattice is a powerful open-source platform designed to simplify the deployment and management of containerized applications. It provides features like service discovery, routing, load balancing, and automated container orchestration, making it ideal for developers and DevOps teams looking to streamline their workflows. This comprehensive guide will walk you through the installation process, covering different methods and configurations to suit your specific needs.
## Understanding Lattice Architecture
Before diving into the installation process, it’s crucial to understand the core components of Lattice. This understanding will help you troubleshoot potential issues and make informed decisions during the setup.
* **Lattice API (LAPI):** The central API server that manages the Lattice cluster. It handles requests for deploying, scaling, and managing applications.
* **Receptor:** Agents deployed on each machine in the cluster. They execute tasks assigned by the LAPI, such as starting and stopping containers.
* **Auctioneer:** Responsible for scheduling tasks (e.g., running containers) across the available machines based on resource availability and constraints.
* **Rep:** A process that manages the lifecycle of individual containers, ensuring they are running as expected.
* **Router:** Responsible for routing traffic to the appropriate containers based on configured routes.
* **NATS:** A lightweight messaging system used for communication between Lattice components.
* **Diego Cells:** These are the virtual machines or physical machines that host the containers. Lattice leverages Diego for container management.
## Prerequisites
Before starting the installation, ensure you have the following prerequisites in place:
* **Operating System:** Lattice is typically deployed on Linux-based systems. Popular choices include Ubuntu, CentOS, and RHEL. This guide will generally focus on Ubuntu, but the principles apply to other distributions as well.
* **Virtualization:** Lattice often runs within a virtualized environment. You can use tools like VirtualBox, VMware, or a cloud platform like AWS, Google Cloud Platform, or Azure.
* **Docker:** Docker is essential for running containerized applications. Make sure Docker is installed and running on all machines in the cluster. The specific version of Docker required may depend on the Lattice version you’re installing, so consult the official Lattice documentation for compatibility.
* **Go:** Go programming language is required to build Lattice from source code. Verify that Go is installed and properly configured in your environment.
* **BOSH CLI (Optional):** While not strictly required for all installation methods, BOSH is a powerful tool for managing Lattice deployments, especially in production environments. It provides a consistent way to deploy, update, and manage complex systems.
* **CF CLI (Optional):** If you plan to deploy Cloud Foundry applications on Lattice, you’ll need the Cloud Foundry Command Line Interface (CF CLI).
* **Sufficient Resources:** Ensure your machines have enough CPU, memory, and disk space to run the Lattice components and your containerized applications. Resource requirements will vary depending on the size and complexity of your deployments.
* **Network Connectivity:** Proper network connectivity is crucial for communication between Lattice components. Ensure that all machines in the cluster can communicate with each other on the necessary ports.
* **DNS Configuration:** Proper DNS resolution is required for service discovery and routing. You may need to configure DNS records to point to the Lattice Router.
* **Internet Access:** The installation process may require downloading packages and dependencies from the internet. Ensure your machines have internet access.
## Installation Methods
There are several ways to install Lattice, each with its own advantages and disadvantages:
1. **BOSH:** This is the recommended method for production deployments. BOSH provides a robust and automated way to deploy, update, and manage Lattice. It handles complex configurations and dependencies, making it easier to maintain the system over time.
2. **Vagrant:** Vagrant is a convenient tool for development and testing environments. It allows you to create a virtual machine with Lattice pre-configured, making it easy to get started quickly.
3. **Manual Installation:** This method involves manually installing and configuring each Lattice component. It provides the most control over the installation process but is also the most complex and time-consuming.
4. **Minikube (For specific use cases):** Lattice components can be deployed within a Minikube Kubernetes cluster for experimentation and local development. However, this is not a typical or fully supported production deployment scenario.
This guide will primarily focus on the BOSH installation method, as it’s the most common and recommended for production environments. We will also provide a brief overview of the Vagrant method for development purposes.
## Installing Lattice with BOSH
BOSH (BOSH Outer Shell) is a powerful open-source toolchain for release engineering, deployment, lifecycle management, and monitoring of distributed systems. It’s particularly well-suited for deploying complex applications like Lattice.
### Step 1: Install BOSH CLI
The first step is to install the BOSH CLI on your workstation. You can download the BOSH CLI from the official BOSH website or use a package manager.
**For Ubuntu/Debian:**
bash
sudo apt-get update
sudo apt-get install ruby ruby-dev build-essential zlib1g-dev
sudo gem install bosh_cli
**For macOS:**
bash
brew install ruby
sudo gem install bosh_cli
After installing the BOSH CLI, verify that it’s working correctly by running:
bash
bosh version
You should see the BOSH CLI version information.
### Step 2: Choose an Infrastructure Provider
BOSH supports various infrastructure providers, including AWS, Google Cloud Platform, Azure, and OpenStack. Choose the provider that best suits your needs. This guide will focus on AWS, but the general principles apply to other providers as well.
### Step 3: Create a BOSH Director
The BOSH Director is the central component of the BOSH system. It’s responsible for managing deployments and monitoring the health of the system. You’ll need to create a BOSH Director in your chosen infrastructure provider. The process of creating a BOSH director is quite involved, but here’s a general outline. Specific details will depend on your IaaS (Infrastructure as a Service) provider.
1. **Create Cloud Config:** Define your infrastructure specifics. This includes details like network configurations, security groups, instance sizes, and availability zones. This configuration is typically stored in a `cloud-config.yml` file.
2. **Create a BOSH environment:** Use `bosh create-env` command, providing the cloud config and a BOSH deployment manifest (often referencing a stemcell).
3. **Secure your BOSH director:** Implement proper security measures, including securing the SSH access and configuring appropriate firewall rules.
For AWS, you can use the AWS CloudFormation template provided by the BOSH team to create a BOSH Director. This usually creates a VPC, security groups, IAM roles, and the BOSH Director VM.
Detailed instructions for creating a BOSH Director on each infrastructure provider can be found in the official BOSH documentation.
### Step 4: Configure the BOSH CLI
Once the BOSH Director is running, you need to configure the BOSH CLI to connect to it. You’ll typically need the following information:
* **BOSH Director Address:** The IP address or hostname of the BOSH Director.
* **BOSH Director Username:** The username for accessing the BOSH Director (usually `admin`).
* **BOSH Director Password:** The password for accessing the BOSH Director.
* **CA Certificate:** The CA certificate for verifying the BOSH Director’s SSL certificate.
Use the following commands to configure the BOSH CLI:
bash
bosh alias-alias director
bosh login
The `bosh login` command will prompt you for the username and password.
### Step 5: Download the Lattice Release
Download the latest Lattice release from the Cloud Foundry GitHub repository:
bash
wget https://github.com/cloudfoundry/lattice-release/releases/download/v
Replace `
### Step 6: Upload the Lattice Release to the BOSH Director
Upload the Lattice release to the BOSH Director using the following command:
bash
bosh upload-release lattice-
### Step 7: Download a Stemcell
A stemcell is a base operating system image that BOSH uses to create virtual machines. Download a stemcell that’s compatible with your infrastructure provider and the Lattice release.
bash
wget https://bosh.io/d/stemcells/bosh-stemcell-ubuntu-trusty-go_agent?v=
Replace `
### Step 8: Upload the Stemcell to the BOSH Director
Upload the stemcell to the BOSH Director using the following command:
bash
bosh upload-stemcell stemcell.tgz
### Step 9: Create a Deployment Manifest
A deployment manifest is a YAML file that describes the configuration of your Lattice deployment. It specifies the number of instances, the resources allocated to each instance, and other settings. You can find example deployment manifests in the Lattice documentation or generate one using a tool like `bosh create-env` with a suitable template.
A typical deployment manifest will include sections for:
* **`name`:** The name of the deployment.
* **`releases`:** The Lattice release you uploaded.
* **`stemcells`:** The stemcell you uploaded.
* **`instance_groups`:** The different types of instances in the deployment (e.g., `lapi`, `receptor`, `auctioneer`).
* **`networks`:** The network configuration for the deployment.
* **`properties`:** Configuration properties for the Lattice components.
**Example Snippet (Illustrative):**
yaml
name: lattice
releases:
– name: lattice
version: latest
stemcells:
– alias: default
os: ubuntu-trusty
version: latest
instance_groups:
– name: lapi
instances: 1
vm_type: default
stemcell: default
networks:
– name: default
jobs:
– name: lapi
release: lattice
# … (other instance groups)
**Important properties to configure include:**
* **`lattice.subnet`:** The subnet for the Lattice network.
* **`lattice.external_domain`:** The external domain name for accessing Lattice applications.
* **`lattice.receptor_count`:** The number of Receptor instances.
### Step 10: Deploy Lattice
Deploy Lattice using the following command:
bash
bosh deploy
Replace `
BOSH will now start deploying Lattice. This process may take some time, depending on the size and complexity of your deployment. You can monitor the progress by watching the BOSH logs.
### Step 11: Verify the Installation
After the deployment is complete, verify that Lattice is running correctly by checking the status of the BOSH deployments:
bash
bosh deployments
You should see the `lattice` deployment listed with a `deployed` status. You can also check the status of individual instances using:
bash
bosh instances
This command will show the status of each instance in the deployment, including the `lapi`, `receptor`, `auctioneer`, and other components.
Finally, you can try deploying a simple containerized application to Lattice to ensure that everything is working correctly. Use the `cf push` command (if you have the CF CLI installed) or use the Lattice API directly to deploy an application.
## Installing Lattice with Vagrant
Vagrant is a tool for building and managing virtual machine environments. It provides a convenient way to get started with Lattice quickly, especially for development and testing purposes.
### Step 1: Install Vagrant and VirtualBox
Download and install Vagrant and VirtualBox from their respective websites.
### Step 2: Clone the Lattice Vagrant Repository
Clone the Lattice Vagrant repository from GitHub:
bash
git clone https://github.com/cloudfoundry/lattice-vagrant
cd lattice-vagrant
### Step 3: Start the Vagrant Environment
Start the Vagrant environment using the following command:
bash
vagrant up
Vagrant will now create a virtual machine with Lattice pre-configured. This process may take some time, as it needs to download and install the necessary dependencies.
### Step 4: Access the Lattice Environment
Once the Vagrant environment is running, you can access it using SSH:
bash
vagrant ssh
You are now logged into the Lattice virtual machine. You can use the Lattice CLI (if installed) or the Lattice API to deploy and manage containerized applications.
## Troubleshooting
Here are some common issues you might encounter during the Lattice installation process and how to resolve them:
* **BOSH Director Connection Issues:** If you’re unable to connect to the BOSH Director, check the BOSH Director address, username, password, and CA certificate. Ensure that the BOSH Director is running and accessible from your workstation.
* **Stemcell or Release Upload Errors:** If you encounter errors while uploading the stemcell or release, verify that the files are not corrupted and that you have sufficient permissions to upload them to the BOSH Director.
* **Deployment Failures:** If the deployment fails, examine the BOSH logs for error messages. Common causes of deployment failures include incorrect configuration settings, resource limitations, and network connectivity issues.
* **Container Deployment Issues:** If you’re unable to deploy containers to Lattice, check the Lattice API endpoint, network configuration, and resource availability. Ensure that the Lattice components are running correctly and that the containers have access to the necessary resources.
* **DNS Resolution Problems:** If you experience DNS resolution problems, verify that the DNS records are configured correctly and that the Lattice Router is able to resolve the domain names.
