Shell JQ : Format output to specific string with delimeter

I want to have an output that instead of delimeter space it should be like this ", " using jq

nodes.json

{
  "nodes": {
    "node1.local": {
      ":ip": "10.0.0.1",
      "ports": [],
      ":memory": 1024,
      ":bootstrap": "bootstrap.sh"
    },
    "node2.local": {
      ":ip": "10.0.0.2",
      "ports": [],
      ":memory": 1024,
      ":bootstrap": "bootstrap.sh"
    },
    "node3.local": {
      ":ip": "10.0.0.3",
      "ports": [],
      ":memory": 1024,
      ":bootstrap": "bootstrap.sh"
    }
  }
}

here is my command use

ips=`cat /vagrant/nodes.json | jq -r '.nodes | to_entries[] | [.value.":ip"] | @tsv'`
echo [\"$ips\"]

where the output is 

["10.0.0.1 10.0.0.2 10.0.0.3"]

and i want it to be like this

["10.0.0.1", "10.0.0.2", "10.0.0.3"]

$ jq -c '.nodes | to_entries | map(.value.":ip")' input
["10.0.0.1","10.0.0.2","10.0.0.3"]
