Downloading specific VCF bundles via CLI

I wanted to reuse my VCF downloaded bundles on another SDDC Manager system so that i wont have to download it from internet again. I found an easy guide here in the VMware documentation. My goal was to download the specific bundle once and upload it on other SDDC Managers.

The first command from SDDC manager was to list the bundles. The lcm bundle transfer utility can be found in /opt/vmware/vcf/lcm/lcm-tools/bin

./lcm-bundle-transfer-util -du ${depotUser} -l -p ${product_version}

I replaced the ${depotUser} with my vmware email address and ${product_version} with the version of the VCF product i wanted to install in my case 5.0.0.0. I was greeted with a list of bundle IDs and the specific component that it was for:

Enter Myvmware user password:
Validating the depot user credentials...

Bundle         Product  Bundle Size  Components
               Version  (in MB)
bundle-80035   5.0.0.0  599.5 MB     ESX_HOST-8.0.1-21813344
bundle-80031   5.0.0.0  10089.9 MB   NSX_T_MANAGER-4.1.0.2.0-21761691
bundle-80029   5.0.0.0  2044.7 MB    SDDC_MANAGER_VCF-5.0.0.0-21822418
bundle-80030   5.0.0.0  251.3 MB     SDDC_MANAGER_VCF-5.0.0.0-21822418
bundle-80033   5.0.0.0  9867.6 MB    VCENTER-8.0.1.00100-21815093

In my case i need the installer. To download a specific bundle we run

./lcm-bundle-transfer-util --download --outputDirectory ${absolute-path-output-dir} --depotUser ${depotUser} -b ${bundle_name}

in my case it was:

./lcm-bundle-transfer-util --download --outputDirectory /some/temporary/location --depotUser [email protected] -b bundle-80029

This allowed me to grab the download from /some/temporary/path and save it/upload it on my other SDDC Managers that were missing it.

Finally before the patch can be used in SDDC Manager we need to upload it to the repo. Please note that once we issue the upload command the download gets deleted, so make sure you save the download ahead of time

./lcm-bundle-transfer-util --upload --bundleDirectory /some/temporary/path -b bundle-80029

Once the upload was complete i was able to see it in SDDC Manager as an package that i can apply.

SaltStack Config vs. Ansible Tower: A Comparison of Two Powerful Configuration Management Solutions

SaltStack Config and Ansible Tower are two powerful configuration management and infrastructure automation tools that cater to the needs of DevOps teams across the globe. While SaltStack Config is an open-source solution, Ansible Tower is the commercial, enterprise-ready version of Ansible Open Source. In this blog post, we will compare SaltStack Config and Ansible Tower in terms of architecture, ease of use, scalability, and features to help you make an informed decision on which tool is best suited for your requirements.

  1. Architecture:

SaltStack Config: SaltStack Config employs a master-minion architecture, where a central master server controls multiple minion nodes. This structure enables powerful parallel processing, as the master server can send commands to all connected minions simultaneously. SaltStack uses a ZeroMQ-based messaging protocol for communication between the master and minions, ensuring better performance and lower latency compared to SSH-based solutions.

Ansible Tower: Ansible Tower is built on top of the open-source Ansible project and retains its agentless architecture, where all operations are executed on target nodes via SSH (or WinRM for Windows hosts). However, Ansible Tower adds a powerful web-based user interface, role-based access control, and centralized management capabilities to the core Ansible features.

  1. Ease of Use:

SaltStack Config: SaltStack Config utilizes YAML-based configuration files called “states” to define the desired configuration of a system. The tool uses Jinja2 templating, allowing for dynamic configuration generation and flexibility in managing complex environments. SaltStack Config also offers a secure data management system called “Pillar” for storing and handling sensitive data.

Ansible Tower: Ansible Tower provides a user-friendly web interface, making it easier for teams to manage their infrastructure without requiring deep knowledge of the underlying Ansible Open Source technology. Like SaltStack Config, Ansible Tower also uses YAML-based configuration files (playbooks) and supports Jinja2 templating.

  1. Scalability:

SaltStack Config: The master-minion architecture of SaltStack Config allows it to handle thousands of nodes efficiently, making it a popular choice for large-scale deployments. While a single master server can become a bottleneck in very large environments, this issue can be mitigated using techniques like multi-master setups or syndics.

Ansible Tower: Ansible Tower enhances the scalability of Ansible Open Source through features like clustering, which allows multiple Tower instances to work together to manage large-scale infrastructures. While the underlying agentless architecture still presents some scalability challenges, Ansible Tower addresses them to a significant extent with enterprise-grade features.

  1. Features:

SaltStack Config: SaltStack Config offers powerful features like parallel execution, event-driven automation, and remote execution, making it a versatile and efficient choice for configuration management and infrastructure automation. Additionally, the tool provides extensive support for cloud platforms, container management, and network automation.

SaltStack Config vs. Ansible Open Source: A Technical Comparison

SaltStack Config and Ansible Open Source are two popular configuration management and infrastructure automation tools used by DevOps teams across the globe. Both solutions have their own unique set of features, advantages, and drawbacks. In this blog post, we will compare SaltStack Config (formerly known as Salt) and Ansible Open Source in terms of their architecture, ease of use, scalability, and community support, to help you make an informed decision on which tool is best suited for your needs.

  1. Architecture:

SaltStack Config: SaltStack Config is built on a master-minion architecture, where a central master server controls multiple minion nodes. This structure enables powerful parallel processing, as the master server can send commands to all connected minions simultaneously. SaltStack uses a ZeroMQ-based messaging protocol for communication between the master and minions.

Ansible Open Source: Ansible, on the other hand, relies on an agentless architecture, where all operations are executed on the target nodes via SSH (or WinRM for Windows hosts). This approach simplifies deployment and reduces overhead, as there is no need to install any software on the target nodes.

  1. Ease of Use:

SaltStack Config: SaltStack Config utilizes YAML-based configuration files called “states” to define the desired configuration of a system. The tool uses Jinja2 templating, which allows for dynamic configuration generation. Additionally, SaltStack Config offers a feature called “Pillar” for securely managing sensitive data.

Ansible Open Source: Ansible also uses YAML-based configuration files called “playbooks” to define the desired state of a system. The tool supports Jinja2 templating as well and has a built-in mechanism for managing sensitive data called “Ansible Vault.” The learning curve for Ansible is generally considered to be lower than that of SaltStack Config, mainly because of its agentless architecture and more straightforward syntax.

  1. Scalability:

SaltStack Config: Due to its master-minion architecture, SaltStack Config can handle thousands of nodes efficiently. The parallel execution of tasks significantly reduces the time required for configuration management and orchestration. However, a single master server can become a bottleneck in very large-scale deployments.

Ansible Open Source: Ansible’s agentless architecture can make it less scalable than SaltStack Config in large environments. The performance of Ansible largely depends on the resources available on the control node, as it must establish and maintain SSH connections with each target host. Nevertheless, it is possible to mitigate scalability issues by using tools like Ansible Tower or by employing techniques such as parallelism and batching.

  1. Community Support:

SaltStack Config: SaltStack Config has a robust and active community that regularly contributes to its development. However, since the acquisition of SaltStack by VMware in 2020, the future of the open-source edition is uncertain, and the community may become more fragmented.

Ansible Open Source: Ansible has a large and active community of users and contributors, and it is backed by Red Hat, which was acquired by IBM in 2019. The tool has continued to grow in popularity, and the open-source edition enjoys regular updates and a rich ecosystem of third-party modules and plugins.

Conclusion:

Both SaltStack Config and Ansible Open Source are powerful configuration management and infrastructure automation tools, each with its own strengths and weaknesses. The choice between the two largely depends on your specific requirements, infrastructure size, and familiarity with the tools. While SaltStack Config offers better scalability and parallel execution, Ansible Open Source provides a more straightforward learning curve and agentless architecture. Ultimately, you should evaluate both tools within the context of your environment to determine the best fit.
