/*
|
|
|
|
The goal here is to map a hostname:port combination to another hostname:port
|
|
combination. The original hostname:port gives the name and regular KV port
|
|
of a couchbase server. We want to determine the corresponding SSL KV port.
|
|
|
|
To do this, we have a pool services structure, as obtained from
|
|
the /pools/default/nodeServices API.
|
|
|
|
For a fully configured two-node system, the structure may look like this:
|
|
{"rev":32,"nodesExt":[
|
|
{"services":{"mgmt":8091,"mgmtSSL":18091,"fts":8094,"ftsSSL":18094,"indexAdmin":9100,"indexScan":9101,"indexHttp":9102,"indexStreamInit":9103,"indexStreamCatchup":9104,"indexStreamMaint":9105,"indexHttps":19102,"capiSSL":18092,"capi":8092,"kvSSL":11207,"projector":9999,"kv":11210,"moxi":11211},"hostname":"172.23.123.101"},
|
|
{"services":{"mgmt":8091,"mgmtSSL":18091,"indexAdmin":9100,"indexScan":9101,"indexHttp":9102,"indexStreamInit":9103,"indexStreamCatchup":9104,"indexStreamMaint":9105,"indexHttps":19102,"capiSSL":18092,"capi":8092,"kvSSL":11207,"projector":9999,"kv":11210,"moxi":11211,"n1ql":8093,"n1qlSSL":18093},"thisNode":true,"hostname":"172.23.123.102"}]}
|
|
|
|
In this case, note the "hostname" fields, and the "kv" and "kvSSL" fields.
|
|
|
|
For a single-node system, perhaps brought up for testing, the structure may look like this:
|
|
{"rev":66,"nodesExt":[
|
|
{"services":{"mgmt":8091,"mgmtSSL":18091,"indexAdmin":9100,"indexScan":9101,"indexHttp":9102,"indexStreamInit":9103,"indexStreamCatchup":9104,"indexStreamMaint":9105,"indexHttps":19102,"kv":11210,"kvSSL":11207,"capi":8092,"capiSSL":18092,"projector":9999,"n1ql":8093,"n1qlSSL":18093},"thisNode":true}],"clusterCapabilitiesVer":[1,0],"clusterCapabilities":{"n1ql":["enhancedPreparedStatements"]}}
|
|
|
|
Here, note that there is only a single entry in the "nodeExt" array and that it does not have a "hostname" field.
|
|
We will assume that either hostname fields are present, or there is only a single node.
