that performs the health check, exits with an appropriate exit code, and potentially
generates some output. A script is paired with an invocation interval (e.g.
every 30 seconds). This is similar to the Nagios plugin system. The output of
a script check is limited to 4KB. Output larger than this will be truncated.
By default, Script checks will be configured with a timeout equal to 30 seconds.
It is possible to configure a custom Script check timeout value by specifying the
`timeout` field in the check definition. When the timeout is reached on Windows,
Consul will wait for any child processes spawned by the script to finish. For any
other system, Consul will attempt to force-kill the script and any child processes
it has spawned once the timeout has passed.
In Consul 0.9.0 and later, script checks are not enabled by default. To use them you
can either use :
- [`enable_local_script_checks`](/docs/agent/config/cli-flags#_enable_local_script_checks):
enable script checks defined in local config files. Script checks defined via the HTTP
API will not be allowed.
- [`enable_script_checks`](/docs/agent/config/cli-flags#_enable_script_checks): enable
script checks regardless of how they are defined.
~> **Security Warning:** Enabling script checks in some configurations may
introduce a remote execution vulnerability which is known to be targeted by
malware. We strongly recommend `enable_local_script_checks` instead. See [this
blog post](https://www.hashicorp.com/blog/protecting-consul-from-rce-risk-in-specific-configurations)
for more details.
- `HTTP + Interval` - These checks make an HTTP `GET` request to the specified URL,
waiting the specified `interval` amount of time between requests (eg. 30 seconds).
The status of the service depends on the HTTP response code: any `2xx` code is
considered passing, a `429 Too ManyRequests` is a warning, and anything else is
a failure. This type of check
should be preferred over a script that uses `curl` or another external process
to check a simple HTTP operation. By default, HTTP checks are `GET` requests
unless the `method` field specifies a different method. Additional header
fields can be set through the `header` field which is a map of lists of
strings, e.g. `{"x-foo": ["bar", "baz"]}`. By default, HTTP checks will be
configured with a request timeout equal to 10 seconds.
It is possible to configure a custom HTTP check timeout value by
specifying the `timeout` field in the check definition. The output of the
check is limited to roughly 4KB. Responses larger than this will be truncated.
HTTP checks also support TLS. By default, a valid TLS certificate is expected.
Certificate verification can be turned off by setting the `tls_skip_verify`
field to `true` in the check definition. When using TLS, the SNI will be set
automatically from the URL if it uses a hostname (as opposed to an IP address);
the value can be overridden by setting `tls_server_name`.
Consul follows HTTP redirects by default. Set the `disable_redirects` field to
`true` to disable redirects.
- `TCP + Interval` - These checks make a TCP connection attempt to the specified
IP/hostname and port, waiting `interval` amount of time between attempts
(e.g. 30 seconds). If no hostname
is specified, it defaults to "localhost". The status of the service depends on
whether the connection attempt is successful (ie - the port is currently
accepting connections). If the connection is accepted, the status is
`success`, otherwise the status is `critical`. In the case of a hostname that
resolves to both IPv4 and IPv6 addresses, an attempt will be made to both
addresses, and the first successful connection attempt will result in a
successful check. This type of check should be preferred over a script that
uses `netcat` or another external process to check a simple socket operation.
By default, TCP checks will be configured with a request timeout of 10 seconds.
It is possible to configure a custom TCP check timeout value by specifying the
`timeout` field in the check definition.
- `UDP + Interval` - These checks direct the client to periodically send UDP datagrams
to the specified IP/hostname and port. The duration specified in the `interval` field sets the amount of time
between attempts, such as `30s` to indicate 30 seconds. The check is logged as healthy if any response from the UDP server is received. Any other result sets the status to `critical`.
The default interval for, UDP checks is `10s`, but you can configure a custom UDP check timeout value by specifying the
`timeout` field in the check definition. If any timeout on read exists, the check is still considered healthy.
- `Time to Live (TTL)` ((#ttl)) - These checks retain their last known state
for a given TTL. The state of the check must be updated periodically over the HTTP
interface. If an external system fails to update the status within a given TTL,
the check is set to the failed state. This mechanism, conceptually similar to a
dead man's switch, relies on the application to directly report its health. For
example, a healthy app can periodically `PUT` a status update to the HTTP endpoint;
if the app fails, the TTL will expire and the health check enters a critical state.
The endpoints used to update health information for a given check are: [pass](/api-docs/agent/check#ttl-check-pass),
[warn](/api-docs/agent/check#ttl-check-warn), [fail](/api-docs/agent/check#ttl-check-fail),
and [update](/api-docs/agent/check#ttl-check-update). TTL checks also persist their
last known status to disk. This allows the Consul agent to restore the last known
status of the check across restarts. Persisted check status is valid through the
end of the TTL from the time of the last check.
- `Docker + Interval` - These checks depend on invoking an external application which
is packaged within a Docker Container. The application is triggered within the running
container via the Docker Exec API. We expect that the Consul agent user has access
to either the Docker HTTP API or the unix socket. Consul uses `$DOCKER_HOST` to
determine the Docker API endpoint. The application is expected to run, perform a health
check of the service running inside the container, and exit with an appropriate exit code.
The check should be paired with an invocation interval. The shell on which the check
has to be performed is configurable which makes it possible to run containers which
have different shells on the same host. Check output for Docker is limited to
4KB. Any output larger than this will be truncated. In Consul 0.9.0 and later, the agent
must be configured with [`enable_script_checks`](/docs/agent/config/cli-flags#_enable_script_checks)
set to `true` in order to enable Docker health checks.
- `gRPC + Interval` - These checks are intended for applications that support the standard
[gRPC health checking protocol](https://github.com/grpc/grpc/blob/master/doc/health-checking.md).
The state of the check will be updated by probing the configured endpoint, waiting `interval`
amount of time between probes (eg. 30 seconds). By default, gRPC checks will be configured
with a default timeout of 10 seconds.
It is possible to configure a custom timeout value by specifying the `timeout` field in
the check definition. gRPC checks will default to not using TLS, but TLS can be enabled by
setting `grpc_use_tls` in the check definition. If TLS is enabled, then by default, a valid
TLS certificate is expected. Certificate verification can be turned off by setting the
`tls_skip_verify` field to `true` in the check definition.
To check on a specific service instead of the whole gRPC server, add the service identifier after the `gRPC` check's endpoint in the following format `/:service_identifier`.
- `H2ping + Interval` - These checks test an endpoint that uses http2
by connecting to the endpoint and sending a ping frame. TLS is assumed to be configured by default.
To disable TLS and use h2c, set `h2ping_use_tls` to `false`. If the ping is successful
within a specified timeout, then the check is updated as passing.
The timeout defaults to 10 seconds, but is configurable using the `timeout` field. If TLS is enabled a valid
certificate is required, unless `tls_skip_verify` is set to `true`.
The check will be run on the interval specified by the `interval` field.
- `Alias` - These checks alias the health state of another registered
node or service. The state of the check will be updated asynchronously, but is
nearly instant. For aliased services on the same agent, the local state is monitored
and no additional network resources are consumed. For other services and nodes,
the check maintains a blocking query over the agent's connection with a current
server and allows stale requests. If there are any errors in watching the aliased
node or service, the check state will be critical. For the blocking query, the
check will use the ACL token set on the service or check definition or otherwise
will fall back to the default ACL token set with the agent (`acl_token`).

Consul-Terraform-Sync compatible modules follow the [standard module structure](https://www.terraform.io/docs/modules/index.html#standard-module-structure). Modules can use syntax supported by Terraform version 0.13, or higher. Consul-Terraform-Sync is designed to integrate with any module that satisfies these [specifications](/docs/nia/terraform-modules#module-specifications). The guide will give you an introduction of the code structure and the basics of authoring a plugin that Terraform can interact with.
It is recommended that partners develop modules that cater to specific workflows on an individual platform in their product portfolio rather than having overarching modules that try to cover multiple workflows across different platforms. This is to keep the automation modular and adoptable by a broad set of users with varying network infrastructure topologies. Partners are encouraged to test the functionality of the modules against their supported platforms.

**Data Plane**: These integrations extend Consul’s certificate management, secure ACL configuration, observability metrics and logging, and service discovery that allows for dynamic service mapping APM and logging tools, extend sidecar proxies to support Consul connect, and extend API gateways to allow Consul to route incoming traffic to the proxies for Connect-enabled services.

**Control Plane**: Consul has a client-server architecture and is the control plane for the service mesh.
**Platform**: These integrations leverage automation of Consul agent deployment, configuration, and management. Designed to be platform agnostic, Consul can be deployed in a variety of form factors, including major Public Cloud providers (AWS, GCP, Azure) as well as in bare-metal, virtual machine, and container (Docker, Kubernetes) environments. They include the Consul agent running in both client and server mode.
**Infrastructure**: There are two integration options in this category: natively through a direct integration with Consul or via Consul-Terraform-Sync (CTS). By leveraging Consul’s powerful **Network Infrastructure Automation (NIA)*** capabilities through CTS, changes in an infrastructure are seamlessly automated when Consul detects a change in its service catalog. For example, these integrations could be used to automate IP updates of load balancers or firewall security policies by leveraging Consul service discovery.

**HCP Consul**: The process to configure a testing instance of HCP consul [is very simple](https://learn.hashicorp.com/tutorials/cloud/get-started-consul). HCP has been designed as a HashiCorp managed service so configuration is minimal as only Consul client agents need to be installed. Furthermore, HashiCorp provides all new users an initial credit which should last approximately 2 months using a [development cluster](https://cloud.hashicorp.com/pricing/consul). When deployed with AWS free tier services, there should be no cost beyond the time spent by the designated tester.

CTS is a daemon that runs alongside Consul, similar to other Consul ecosystem tools like Consul Template. CTS is not included with the Consul binary and needs to be installed separately.

### Run an Agent
The Consul agent must be running in order to dynamically update network devices. To run the local Consul agent, you can run Consul in development mode which can be started with `consul agent -dev` for simplicity. For more details on running Consul agent, refer to the [Getting Started: Run the Consul Agent Tutorial](https://learn.hashicorp.com/tutorials/consul/get-started-agent?in=consul/getting-started).

When running a Consul agent with CTS in production, we suggest to keep a few considerations in mind. CTS uses [blocking queries](/api-docs/features/blocking) to monitor task dependencies, like changes to registered services. This results in multiple long running TCP connections between CTS and the agent to poll changes for each dependency. Monitoring a high number of services may quickly hit the default Consul agent connection limits.

This will walk you through the steps of running multiple Consul agents and then joining them together into a cluster.

### How to Create a Provider
If there is no existing Terraform provider, a new Terraform provider can be [created](https://learn.hashicorp.com/tutorials/terraform/provider-setup) and [published](https://www.terraform.io/docs/registry/providers/publishing.html). The provider can then be used within a network integration task by authoring a compatible Terraform module.

- **Streaming Enabled by Default for Service Health:** Streaming is a major architectural enhancement in how update notifications for blocking queries are delivered within the cluster which significantly reduces CPU and network bandwidth usage for large-scale Consul deployments. In Consul 1.10, streaming is now available for the service health HTTP endpoint and is enabled by default.
- **Redesigned UI and Observability Enhancements:** The Consul UI has been redesigned with a new sidebar layout. Additionally, Kubernetes users now have the ability to deploy Prometheus via the Consul Helm chart which automatically integrates it with Consul’s Service Visualization UI for displaying traffic metrics between services. Lastly, Pod and Envoy metrics can now be exposed to Prometheus using Kubernetes annotations via a single aggregated endpoint.

- **Deprecation of Legacy ACL System:** In Consul 1.4, we upgraded to a new Access Controls (ACLs) system. This upgrade made improvements in Consul’s ACL system handles the API, Tokens, and Policies. With Consul 1.10, the legacy system is officially deprecated, and will be removed from Consul in a later release. We strongly recommend that users begin the process of migrating to the newer ACL system.

- **Application-Aware Intentions:** A new set of capabilities that extends Consul’s intentions model to support Layer 7 request information. Intentions now provide the ability for operators to construct policies which evaluate application-layer information such as HTTP Path, Headers, or Method – in addition to service identity – when authorizing HTTP-based (HTTP/1.1, HTTP/2, gRPC) service-to-service communication.

- **Service Mesh Visualization:** This addition provides a new topology tab to the Consul UI which displays topology diagrams and key service mesh metrics like request, error rates, and timing metrics. These new features will assist developers and operators in verifying configuration and troubleshooting issues within the service mesh. The UI also supports deep linking into your external metrics dashboards.
