* Rename Intermediate cert references to LeafSigningCert Within the Consul CA subsystem, the term "Intermediate" is confusing because the meaning changes depending on provider and datacenter (primary vs secondary). For example, when using the Consul CA the "ActiveIntermediate" may return the root certificate in a primary datacenter. At a high level, we are interested in knowing which CA is responsible for signing leaf certs, regardless of its position in a certificate chain. This rename makes the intent clearer. * Move provider state check earlier * Remove calls to GenerateLeafSigningCert GenerateLeafSigningCert (formerly known as GenerateIntermediate) is vestigial in non-Vault providers, as it simply returns the root certificate in primary datacenters. By folding Vault's intermediate cert logic into `GenerateRoot` we can encapsulate the intermediate cert handling within `newCARoot`. * Move GenerateLeafSigningCert out of PrimaryProvidder Now that the Vault Provider calls GenerateLeafSigningCert within GenerateRoot, we can remove the method from all other providers that never used it in a meaningful way. * Add test for IntermediatePEM * Rename GenerateRoot to GenerateCAChain "Root" was being overloaded in the Consul CA context, as different providers and configs resulted in a single root certificate or a chain originating from an external trusted CA. Since the Vault provider also generates intermediates, it seems more accurate to call this a CAChain. |

Consul
Consul is a distributed, highly available, and data center aware solution to connect and configure applications across dynamic, distributed infrastructure.
- Website: https://www.consul.io
- Tutorials: HashiCorp Learn
- Forum: Discuss
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 - Consul Service Mesh 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 with Transparent Proxy.
-
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, macOS, FreeBSD, Solaris, and Windows and includes an optional browser based UI. 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.
