Description:	Kubernetes is an open source software for automating deployment, scaling, and management of containerized applications. This technology groups containers that make an application into logical units and offers features such as service discovery and load balancing, automatic binpacking, storage orchestration, and batch execution. Additionally, this technology can be used on-premises, hybrid, or on public cloud infrastructure. The TRM decisions in this entry only apply to technologies and versions owned, operated, managed, patched, and version-controlled by VA. This includes technologies deployed as software installations on VMs within VA-controlled cloud environments (e.g. VA Enterprise Cloud (VAEC)). Cloud services provided by the VAEC, which are listed in the VAEC Service Catalog, and those controlled and managed by an external Cloud Service Provider (i.e. SaaS) are not in the purview of the TRM. For more information on the use of cloud services and cloud-based products within VA, including VA private clouds, please see the Enterprise Cloud Solutions Office (ECSO) Portal at: https://dvagov.sharepoint.com/sites/OITEPMOECSO

Release/Version Information:

VA decisions for specific versions may include a ‘.x’ wildcard, which denotes a decision that pertains to a range of multiple versions.

For example, a technology approved with a decision for 7.x would cover any version of 7.(Anything) - 7.(Anything). However, a 7.4.x decision would cover any version of 7.4.(Anything), but would not cover any version of 7.5.x or 7.6.x on the TRM.

VA decisions for specific versions may include ‘+’ symbols; which denotes that the decision for the version specified also includes versions greater than what is specified but is not to exceed or affect previous decimal places.

For example, a technology approved with a decision for 12.6.4+ would cover any version that is greater than 12.6.4, but would not exceed the .6 decimal ie: 12.6.401 is ok, 12.6.5 is ok, 12.6.9 is ok, however 12.7.0 or 13.0 is not.

Decision Constraints


[1]	Due to potential information security risks, cloud based technologies may not be used without the approval of the Enterprise Cloud Solution Office (ECSO). This body is in part responsible for ensuring organizational information, Personally Identifiable Information (PII), Protected Health Information (PHI), and VA sensitive data are not compromised. (Ref: VA Directive 6004, VA Directive 6517, VA Directive 6513 and VA Directive 6102).

[2]	Users should check with their supervisor, Information Security Office (ISO) or local OIT representative for permission to download and use this software. Downloaded software must always be scanned for viruses prior to installation to prevent adware or malware. Freeware may only be downloaded directly from the primary site that the creator of the software has advertised for public download and user or development community engagement. Users should note, any attempt by the installation process to install any additional, unrelated software is not approved and the user should take the proper steps to decline those installations.

[3]	Due to National Institute of Standards and Technology (NIST) identified security vulnerabilities, extra vigilance should be applied to ensure the versions remain properly patched to mitigate known and future vulnerabilities. The local ISO can provide assistance in reviewing the NIST vulnerabilities.

[4]	Based on the IPR findings from Security Engineering and pending required VA security policy guidance from OIS DevSecOps on container and orchestrator technology, this technology is only approved for Development and Test systems usage. Production system use of this technology is considered TRM unapproved must have an approved TRM waiver to accept the risks of using this technology in production without required policy and configuration standards. This constraint will be revisited after VA determines relevant policy and creates configuration standard(s). See the reference section and the Baseline Configuration Management website for more information: https://vaww.vashare.oit.va.gov/sites/itops/svcs/sma/BCM/Pages/BCM.aspx Per the Initial Product Review, users must abide by the following constraints: Kubernetes should not be used until the VA develops a container strategy and establishes an enterprise orchestration solution. Kubernetes should not be used to process, store, or transmit VA sensitive information. This technology is currently unapproved due to VA standardization and the lack of a required VA baseline. In order to reduce costs, risk and overhead in many areas including: training, patching, configuration standards, and documentation, VA has standardized the types and configurations of the platforms/technologies it uses and maintains baselines for in its internal operating environment. Without a published DISA STIG or NIST validated checklist, creating a baseline requires substantial effort and significant time and cost. The project team will require written vendor commitment for assistance and continued vendor support and a VA Subject Matter Expert (SME) point of contact with a signed Baseline ownership Memorandum of Understanding (MOU). To begin exploring baseline creation, the project team requesting to use this technology must submit a request for a new product or technology review to Solution Delivery, Security Engineering via the following link: https://vaww.portal2.va.gov/sites/infosecurity/ess/Lists/Request%20New%20ProductTechnology%20Review/AllItems.aspx Security Engineering will work with the project team and the SD Baseline and Configuration Management (BCM) team to identify the appropriate foundational checklist (e.g. DISA SRG, DISA STIG, or NIST Validated Checklist) to use as a basis for the VA security controls checklist. Once provided, the project team will be responsible for working with the product vendor to complete the checklist with special emphasis on VA Check Content and VA Fix text columns with specific commands related to the product. Due to potential information security risks, cloud based technologies may not be used without the approval of the VA Enterprise Cloud Services (ECS) Group. This body is in part responsible for ensuring organizational information, Personally Identifiable Information (PII), Protected Health Information (PHI), and VA sensitive data are not compromised. (Ref: VA Directive 6004, VA Directive 6517, VA Directive 6513 and VA Directive 6102). Open source software may be obtained at no cost. The VA requires support for all software used on the VA network. Vendor or third-party support at an enterprise level is not free and must be acquired for any open source product to be deployed on the VA network. Support for Kubernetes is offered through vendors designated as Kubernetes Certified Service Providers, the Kubernetes community forum, and Kubernetes’ Slack channel.

[5]	Due to potential information security risks for cloud-based technologies, users should coordinate closely with their facility ISSO for guidance and assistance on cloud products. If further guidance is needed contact the Enterprise Cloud Solution Office (ECSO), which is the body responsible for new software development in and migration of existing systems to the VA Enterprise Cloud (VAEC) and ensuring organizational information, Personally Identifiable Information (PII), Protected Health Information (PHI), and VA sensitive data are not compromised within the VAEC. For information about Software as a Service (SaaS) products or to submit a SaaS product request with the Project Special Forces (SPF) team, please use their online form.
