Abstract Concourse is a continuous integration (CI) server. It can be deployed manually or via BOSH. In this blog post, we describe the BOSH deployment of a Concourse CI server to natively accept Secure Sockets Layer (SSL) connections without using a load balancer. This may reduce the complexity and cost [ELB-pricing] of a Concourse deployment. 2016-09-12: This blog post is obsolete. Newer (v2.0.0+) versions of Concourse allow binding to the privileged ports 80 and 443, eliminating the need for an nginx proxy. Here is an example of a BOSH-deployed Concourse server that binds natively to ports 80 & 443: BOSH manifest. 0. Pre-requisites Deploy Concourse with BOSH. Follow the instructions here. ...

vSphere users ask, “How do I configure my BOSH director so that it can communicate with my vCenter but the director’s deployed VMs can’t?” One technique is to use a multi-homed BOSH director combined with the BOSH Networking Release (a BOSH release which enables customization of the VM’s routing table, allowing more routes than the default gateway). Network Diagram The following is a network diagram of our deployment. We want to protect the assets at the top (in blue): the vCenter server and its associated ESXi servers. These machines are particularly sensitive as they control hundreds of VMs. ...

[2016-04-06: This Blog Post is out-of-date; Please refer to the official Concourse documentation for instructions how to install a Concourse server] Continuous Integration (CI) is often used in conjunction with test-driven development (TDD); however, CI servers often bring their own set of challenges: they are usually “snowflakes”, uniquely configured machines that are difficult to upgrade, re-configure, or re-install. [snowflakes] In this blog post, we describe deploying a publicly-accessible, lean (1GB RAM, 1 vCPU, 15GB disk) Concourse CI server using a 350-line manifest. Upgrades/re-configurations/re-installs are as simple as editing a file and typing one command (bosh-init). ...
