Support 'aliases' option on indices.create

[labrown]

This works on elasticsearch 0.90.7 to create an alias at the same time an index is created.

curl -XPUT "https://localhost/foo/" -d'
{
aliases: [ "foo-alias" ]
}'

It would be nice to have this in the Perl API as well.

Hi @labrown

You can already do this. Anything in the request body should be passed in the body parameter:

$e->indices->create(index=>'foo', body=>{ aliases=>['foo-alias']})

But beware... adding aliases at index creation time is not currently supported. In fact, we weren't aware that this would work at all. There's a PR open at the moment to add this exact functionality: elastic/elasticsearch#4920

I've played around with this and found that combining aliases with settings doesn't set the aliases:

curl -XPUT "http://localhost:9200/foo/" -d'
{
  "aliases": [
    "foo-alias"
  ],
  "settings": {
    "number_of_shards": 1
  }
}'

But, including it in the settings DOES work:

curl -XPUT "http://localhost:9200/foo/" -d'
{
  "settings": {
    "number_of_shards": 1,
    "aliases": [
      "foo-alias"
    ]
  }
}'

Interesting. Thanks for letting me know
