Introduction: Vmware ESXI 


What is VMware ESXi?


VMware ESXi, also called VMware ESXi Server, is a bare-metal hypervisor developed by VMware for vSphere. ESXi is one of the primary components in the VMware infrastructure software suite.


ESXi is a Type 1 hypervisor, meaning it runs directly on system hardware without the need for an OS. Type 1 hypervisors are also referred to as bare-metal hypervisors because they run directly on hardware. Hypervisors help run multiple VMs efficiently on a physical server.


What is VMware ESXi Server?


VMware ESXi server is a bare-metal hypervisor (without running an operating system) that can run Virtual Machines.




Key features of VMware ESXi


As a component of vSphere, VMware ESXi supports the following key features:


  • Traffic shaping,

  • Memory ballooning,

  • Role-based security access,

  • Logging and auditing,

  • A GUI,

  • vSphere PowerCLI, and

  • Configuration of up to 768 processor cores.

ESXi benefits and drawbacks


ESXi offers the following advantages:


  • Quick installation: Installing ESXi in a data center is quick and easy because of its lightweight footprint.

  • Fewer patches: ESXi's lightweight format of 150 MB requires fewer patches.

  • ESXi is considered more secure because of its small attack surface. In addition, encryption role-based access, logging, and auditing capabilities are built into the VMkernel.


  • Simplified GUI: ESXi offers the direct console user interface, the vSphere client and a web client that can configure the vSphere environment. The web client, for example, enables an administrator to manage virtual infrastructures without installing vSphere.

How to Use Ansible to Install and Set Up Docker on Ubuntu 22.04

IntroductionServer automation now plays an essential role in systems administration, due to the disposable nature of modern application environments.&nbsp;Configuration management&nbsp;tools such as&nbsp;Ansible&nbsp;are typically used to streamline the process of automating server setup by establishing standard procedures for new servers while also reducing human error associated with manual setups.Ansible offers a simple architecture that doesn’t require special software to be installed on nodes. It also provides a robust set of features and built-in modules which facilitate writing automation scripts.This guide explains how to use Ansible to automate the steps contained in our guide on&nbsp;How To Install and Use Docker on Ubuntu 22.04.&nbsp;Docker&nbsp;is an application that simplifies the process of managing&nbsp;containers, resource-isolated processes that behave in a similar way to virtual machines, but are more portable, more resource-friendly, and depend more heavily on the host operating system.PrerequisitesIn order to execute the automated setup provided by the playbook in this guide, you’ll need:One Ansible control node: an Ubuntu 22.04 machine with Ansible installed and configured to connect to your Ansible hosts using SSH keys. Make sure the control node has a regular user with sudo permissions and a firewall enabled, as explained in our&nbsp;Initial Server Setup&nbsp;guide. To set up Ansible, please follow our guide on&nbsp;How to Install and Configure Ansible on Ubuntu 22.04.One or more Ansible Hosts: one or more remote Ubuntu 22.04 servers previously set up following the guide on&nbsp;How to Use Ansible to Automate Initial Server Setup on Ubuntu 22.04.Before proceeding, you first need to make sure your Ansible control node is able to connect and execute commands on your Ansible host(s). For a connection test, check&nbsp;Step 3&nbsp;of&nbsp;How to Install and Configure Ansible on Ubuntu 22.04.What Does this Playbook Do?This Ansible playbook provides an alternative to manually running through the procedure outlined in our guide on&nbsp;How To Install and Use Docker on Ubuntu 22.04. Set up your playbook once, and use it for every installation after.Running this playbook will perform the following actions on your Ansible hosts:Install&nbsp;aptitude, which is preferred by Ansible as an alternative to the&nbsp;apt&nbsp;package manager.Install the required system packages.Install the Docker GPG APT key.Add the official Docker repository to the&nbsp;apt&nbsp;sources.Install Docker.Install the Python Docker module via&nbsp;pip.Pull the default image specified by&nbsp;default_container_image&nbsp;from Docker Hub.Create the number of containers defined by the&nbsp;container_count&nbsp;variable, each using the image defined by&nbsp;default_container_image, and execute the command defined in&nbsp;default_container_command&nbsp;in each new container.Once the playbook has finished running, you will have a number of containers created based on the options you defined within your configuration variables.To begin, log into a&nbsp;sudo&nbsp;enabled user on your Ansible control node server.Step 1 — Preparing your PlaybookThe&nbsp;playbook.yml&nbsp;file is where all your&nbsp;tasks&nbsp;are defined. A task is the smallest unit of action you can automate using an Ansible playbook. But first, create your playbook file using your preferred text editor:nano playbook.yml CopyThis will open an empty YAML file. Before diving into adding tasks to your playbook, start by adding the following:playbook.yml--- - hosts: all become: true vars: container_count: 4 default_container_name: docker default_container_image: ubuntu default_container_command: sleep 1 CopyAlmost every playbook you come across will begin with declarations similar to this.&nbsp;hosts&nbsp;declares which servers the Ansible control node will target with this playbook.&nbsp;become&nbsp;states whether all commands will be done with escalated&nbsp;root&nbsp;privileges.vars&nbsp;allows you to store data in variables. If you decide to change these in the future, you will only have to edit these single lines in your file. Here’s a brief explanation of each variable:container_count: The number of containers to create.default_container_name: Default container name.default_container_image: Default Docker image to be used when creating containers.default_container_command: Default command to run on new containers.Note:&nbsp;If you want to see the playbook file in its final finished state, jump to&nbsp;Step 5. YAML files can be particular with their indentation structure, so you may want to double-check your playbook once you’ve added all your tasks.Step 2 — Adding Packages Installation Tasks to your PlaybookBy default, tasks are executed synchronously by Ansible in order from top to bottom in your playbook. This means task ordering is important, and you can safely assume one task will finish executing before the next task begins.All tasks in this playbook can stand alone and be re-used in your other playbooks.Add your first tasks of installing&nbsp;aptitude, a tool for interfacing with the Linux package manager, and installing the required system packages. Ansible will ensure these packages are always installed on your server:playbook.yml tasks: - name: Install aptitude apt: name: aptitude state: latest update_cache: true - name: Install required system packages apt: pkg: - apt-transport-https - ca-certificates - curl - software-properties-common - python3-pip - virtualenv - python3-setuptools state: latest update_cache: true CopyHere, you’re using the&nbsp;apt&nbsp;Ansible built-in&nbsp;module&nbsp;to direct Ansible to install your packages. Modules in Ansible are shortcuts to execute operations that you would otherwise have to run as raw bash commands. Ansible safely falls back onto&nbsp;apt&nbsp;for installing packages if&nbsp;aptitude&nbsp;is not available, but Ansible has historically preferred&nbsp;aptitude.You can add or remove packages to your liking. This will ensure all packages are not only present, but on the latest version, and do after an update with&nbsp;apt&nbsp;is called.Step 3 — Adding Docker Installation Tasks to your PlaybookYour task will install the latest version of Docker from the official repository. The Docker GPG key is added to verify the download, the official repository is added as a new package source, and Docker will be installed. Additionally, the Docker module for Python will be installed as well:playbook.yml - name: Add Docker GPG apt Key apt_key: url: https://download.docker.com/linux/ubuntu/gpg state: present - name: Add Docker Repository apt_repository: repo: deb https://download.docker.com/linux/ubuntu jammy stable state: present - name: Update apt and install docker-ce apt: name: docker-ce state: latest update_cache: true - name: Install Docker Module for Python pip: name: docker CopyYou’ll see that&nbsp;&nbsp;apt_key&nbsp;and&nbsp;apt_repository&nbsp;built-in Ansible modules are first pointed at the correct URLs, then tasked to ensure they are present. This allows installation of the latest version of Docker, along with using&nbsp;pip&nbsp;to install of the module for Python.Step 4 — Adding Docker Image and Container Tasks to your PlaybookThe actual creation of your Docker containers starts here with the pulling of your desired Docker image. By default, these images come from the official&nbsp;Docker Hub. Using this image, containers will be created according to the specifications laid out by the variables declared at the top of your playbook:playbook.yml - name: Pull default Docker image community.docker.docker_image: name: "{{ default_container_image }}" source: pull - name: Create default containers community.docker.docker_container: name: "{{ default_container_name }}{{ item }}" image: "{{ default_container_image }}" command: "{{ default_container_command }}" state: present with_sequence: count={{ container_count }} Copydocker_image&nbsp;is used to pull the Docker image you want to use as the base for your containers.&nbsp;docker_container&nbsp;allows you to specify the specifics of the containers you create, along with the command you want to pass them.with_sequence&nbsp;is the Ansible way of creating a loop, and in this case, it will loop the creation of your containers according to the count you specified. This is a basic count loop, so the&nbsp;item&nbsp;variable here provides a number representing the current loop iteration. This number is used here to name your containers.Step 5 — Reviewing your Complete PlaybookYour playbook should look roughly like the following, with minor differences depending on your customizations:playbook.yml--- - hosts: all become: true vars: container_count: 4 default_container_name: docker default_container_image: ubuntu default_container_command: sleep 1d tasks: - name: Install aptitude apt: name: aptitude state: latest update_cache: true - name: Install required system packages apt: pkg: - apt-transport-https - ca-certificates - curl - software-properties-common - python3-pip - virtualenv - python3-setuptools state: latest update_cache: true - name: Add Docker GPG apt Key apt_key: url: https://download.docker.com/linux/ubuntu/gpg state: present - name: Add Docker Repository apt_repository: repo: deb https://download.docker.com/linux/ubuntu jammy stable state: present - name: Update apt and install docker-ce apt: name: docker-ce state: latest update_cache: true - name: Install Docker Module for Python pip: name: docker - name: Pull default Docker image community.docker.docker_image: name: "{{ default_container_image }}" source: pull - name: Create default containers community.docker.docker_container: name: "{{ default_container_name }}{{ item }}" image: "{{ default_container_image }}" command: "{{ default_container_command }}" state: present with_sequence: count={{ container_count }} CopyFeel free to modify this playbook to best suit your individual needs within your own workflow. For example, you could use the&nbsp;docker_image&nbsp;module to push images to Docker Hub or the&nbsp;docker_container&nbsp;module to set up container networks.Note:&nbsp;This is a gentle reminder to be mindful of your indentations. If you run into an error, this is very likely the culprit. YAML suggests using 2 spaces as an indent, as was done in this example.Once you’re satisfied with your playbook, you can exit your text editor and save.Step 6 — Running your PlaybookYou’re now ready to run this playbook on one or more servers. Most playbooks are configured to be executed on every server in your inventory by default, but you’ll specify your server this time.To execute the playbook only on&nbsp;server1, connecting as&nbsp;sammy, you can use the following command:ansible-playbook playbook.yml -l server1 -u sammy CopyThe&nbsp;-l&nbsp;flag specifies your server and the&nbsp;-u&nbsp;flag specifies which user to log into on the remote server. You will get output similar to this:Output. . . changed: [server1] TASK [Create default containers] ***************************************************************************************************************** changed: [server1] =&gt; (item=1) changed: [server1] =&gt; (item=2) changed: [server1] =&gt; (item=3) changed: [server1] =&gt; (item=4) PLAY RECAP *************************************************************************************************************************************** server1 : ok=9 changed=8 unreachable=0 failed=0 skipped=0 rescued=0 ignored=0 Note: For more information on how to run Ansible playbooks, check our&nbsp;Ansible Cheat Sheet Guide.This indicates your server setup is complete! Your output doesn’t have to be exactly the same, but it is important that you have zero failures.When the playbook is finished running, log in via SSH to the server provisioned by Ansible to check if the containers were successfully created.Log in to the remote server with:ssh sammy@your_remote_server_ip CopyAnd list your Docker containers on the remote server:sudo docker ps -a CopyYou should see output similar to this:OutputCONTAINER ID IMAGE COMMAND CREATED STATUS PORTS NAMES a3fe9bfb89cf ubuntu "sleep 1d" 5 minutes ago Created docker4 8799c16cde1e ubuntu "sleep 1d" 5 minutes ago Created docker3 ad0c2123b183 ubuntu "sleep 1d" 5 minutes ago Created docker2 b9350916ffd8 ubuntu "sleep 1d" 5 minutes ago Created docker1 This means the containers defined in the playbook were created successfully. Since this was the last task in the playbook, it also confirms that the playbook was fully executed on this server.ConclusionAutomating your infrastructure setup can not only save you time, but it also helps to ensure that your servers will follow a standard configuration that can be customized to your needs. With the distributed nature of modern applications and the need for consistency between different staging environments, automation like this has become a central component in many teams’ development processes.In this guide, you demonstrated how to use Ansible to automate the process of installing and setting up Docker on a remote server. Because each individual typically has different needs when working with containers, we encourage you to check out the&nbsp;official Ansible documentation&nbsp;for more information and use cases of the&nbsp;docker_container&nbsp;Ansible module.If you’d like to include other tasks in this playbook to further customize your initial server setup, please refer to our introductory Ansible guide&nbsp;Configuration Management 101: Writing Ansible Playbooks.
