Consul Peering Establish

Command: consul peering establish

Corresponding HTTP API Endpoint: [POST] /v1/peering/establish

The peering establish starts a peering connection with the cluster that generated the peering token. You can generate cluster peering tokens using the consul peering generate-token command or the HTTP API.

You can only use a peering token to establish the connection once. If you need to reestablish a peering connection, you must generate a new token.

The table below shows this command's required ACLs.

ACL Required
`peering:write`

Usage

Usage: consul peering establish [options] -name <peer name> -peering-token <token>

Command Options

-name=<string> - (Required) Specifies a local name for the cluster you are establishing a connection with. The name is only used to identify the connection with the peer.
-peering-token=<string> - (Required) Specifies the peering token from the cluster that generated the token.
-meta=<string>=<string> - Specifies key/value pairs to associate with the peering connection in -meta="key"="value" format. You can use the flag multiple times to set multiple metadata fields.

Enterprise Options

-partition=<string> - Enterprise Specifies the admin partition to query. If not provided, the partition is inferred from the request's ACL token, or defaults to the default partition.

API Options

-ca-file=<value> - Path to a CA file to use for TLS when communicating with Consul. This can also be specified via the CONSUL_CACERT environment variable.
-ca-path=<value> - Path to a directory of CA certificates to use for TLS when communicating with Consul. This can also be specified via the CONSUL_CAPATH environment variable.
-client-cert=<value> - Path to a client cert file to use for TLS when verify_incoming is enabled. This can also be specified via the CONSUL_CLIENT_CERT environment variable.
-client-key=<value> - Path to a client key file to use for TLS when verify_incoming is enabled. This can also be specified via the CONSUL_CLIENT_KEY environment variable.
-http-addr=<addr> - Address of the Consul agent with the port. This can be an IP address or DNS address, but it must include the port. This can also be specified via the CONSUL_HTTP_ADDR environment variable. In Consul 0.8 and later, the default value is http://127.0.0.1:8500, and https can optionally be used instead. The scheme can also be set to HTTPS by setting the environment variable CONSUL_HTTP_SSL=true. This may be a unix domain socket using unix:///path/to/socket if the agent is configured to listen that way.
-tls-server-name=<value> - The server name to use as the SNI host when connecting via TLS. This can also be specified via the CONSUL_TLS_SERVER_NAME environment variable.
-token=<value> - ACL token to use in the request. This can also be specified via the CONSUL_HTTP_TOKEN environment variable. If unspecified, the query will default to the token of the Consul agent at the HTTP address.
-token-file=<value> - File containing the ACL token to use in the request instead of one specified via the -token argument or CONSUL_HTTP_TOKEN environment variable. This can also be specified via the CONSUL_HTTP_TOKEN_FILE environment variable.

Examples

The following examples establishes a peering connection with a cluster locally referred to as "cluster-01":

$ consul peering establish -name cluster-01 -peering-token eyJDQSI6bnVs...5Yi0wNzk5NTA1YTRmYjYifQ==
Successfully established peering connection with cluster-01
