Normally the named pipe would buffer up to 64k, but in some cases when a soft limit is reached, they will start only buffering up to 4k. In either case, we should not deadlock. This commit changes the pipe-bootstrap command to first buffer all of stdin into the process, before trying to write it to the named pipe. This allows the process memory to act as the buffer, instead of the named pipe. Also changed the order of operations in `makeBootstrapPipe`. The new test added in this PR showed that simply buffering in the process memory was not enough to fix the issue. We also need to ensure that the `pipe-bootstrap` process is started before we try to write to its stdin. Otherwise the write will still block. Also set stdout/stderr on the subprocess, so that any errors are visible to the user. |

Consul 
- Website: https://www.consul.io
- Tutorials: HashiCorp Learn
- Forum: Discuss
Consul is a distributed, highly available, and data center aware solution to connect and configure applications across dynamic, distributed infrastructure.
Consul provides several key features:
-
Multi-Datacenter - Consul is built to be datacenter aware, and can support any number of regions without complex configuration.
-
Service Mesh/Service Segmentation - Consul Connect enables secure service-to-service communication with automatic TLS encryption and identity-based authorization. Applications can use sidecar proxies in a service mesh configuration to establish TLS connections for inbound and outbound connections without being aware of Connect at all.
-
Service Discovery - Consul makes it simple for services to register themselves and to discover other services via a DNS or HTTP interface. External services such as SaaS providers can be registered as well.
-
Health Checking - Health Checking enables Consul to quickly alert operators about any issues in a cluster. The integration with service discovery prevents routing traffic to unhealthy hosts and enables service level circuit breakers.
-
Key/Value Storage - A flexible key/value store enables storing dynamic configuration, feature flagging, coordination, leader election and more. The simple HTTP API makes it easy to use anywhere.
Consul runs on Linux, Mac OS X, FreeBSD, Solaris, and Windows. A commercial version called Consul Enterprise is also available.
Please note: We take Consul's security and our users' trust very seriously. If you believe you have found a security issue in Consul, please responsibly disclose by contacting us at security@hashicorp.com.
