Sending jq via SSH

Question

When I running jq command locally it works:

jq --arg ip "$IP" '.nodes|.app|.ip = $ip' nodes.json

Output:

{ "nodes": 1, "is_manager": true, "ip": "127.0.0.1", "cpus": 16, "memory": 64 }

But I can't figure out how do I send it remotely via ssh, for example this command returns an error:

 ssh -o StrictHostKeyChecking=no -i key.pem user@"172.13.1.23" "jq --arg ip "127.0.0.1" '.nodes|.app|.ip = $ip' nodes.json"

Output:

jq: error: syntax error, unexpected $end (Unix shell quoting issues?) at , line 1: .nodes|.app|.ip = jq: 1 compile error

Answer 1

$ip is in double quotes, and so is expanded locally. You need to escape the dollar sign.

ssh -o StrictHostKeyChecking=no -i key.pem user@"172.13.1.23" \
  "jq --arg ip "127.0.0.1" '.nodes|.app|.ip = \$ip' nodes.json"
