This blog post describes the procedure we followed to use the beta BOSH command line interface (CLI) to deploy an nginx webserver with a native IPv6 address (i.e. 2600:1f16:0a62:5c00::4) to AWS in addition to its IPv4 Elastic IP address (i.e. 52.15.73.90). We were then able to browse the webserver via the IPv6 protocol. BOSH does not support IPv6. This is a proof-of-concept. Do not apply IPv6 to your production BOSH Directors or to BOSH CLI-deployed systems. ...

VMWare NSX is a network virtualization platform (frequently paired with the vSphere IaaS (Infrastructure as a Service)). It includes features such as Load Balancers (LBs) and firewall rules, features often found in public-facing IaaSes (e.g. AWS (Amazon Web Services), GCE (Google Compute Engine), and Microsoft Azure) but not native to vSphere. BOSH, a VM orchestrator, includes hooks to interoperate with NSX’s LB and Distributed Firewall features. These hooks enable BOSH to attach created VMs to existing NSX Load Balancer Pools and NSX Distributed Firewall rulesets. BOSH uses NSX’s Security Groups [NSX Security Groups] as the underlying mechanism. ...

In this blog post, we describe the procedure we followed in order to create a custom Google Compute Engine (GCE) stemcell with a user cunnie whose ~/.ssh/authorized_keys is pre-populated with a specific public key. Customizing stemcells is highly discouraged — it voids your warranty, and opens a host of problems which will only cause pain. This post is intended as an educational demonstration of the stemcell building process. You have been warned. ...

When PowerDNS released version 4.0.1 of their authoritative nameserver, we rushed to update our BOSH Release (which was at version 4.0.0). We thought it would be a walk in the park, but instead it was an epic fail (a final release which couldn’t be deployed because the blobs were broken). In this blog post we describe the procedure we ultimately followed to successfully create an updated BOSH final release of version 4.0.1 of the PowerDNS authoritative nameserver, highlighting some of the tricky and non-obvious steps. ...

The Concourse Continuous Integration (CI) server has an API endpoint that displays a badge which shows health of your project: http(s)://concourse-server/api/v1/pipelines/pipeline-name/jobs/job-name/badge 0. Abstract Open Source projects that have CI (e.g. Bootstrap, Node.js) often feature status badges (also known as images or icons) to display the health of their projects. CI servers such as Travis CI offer status badges. Concourse CI also offers status badges. The status badge is a Scalable Vector Graphics (SVG) image available from the Concourse API. [Concourse versions] ...
