Command-Cluster

You can use the Zero Trust Host Access capability to send "commands" to a target cluster(s).

Command Payload

In this example, we want to send a command to "ping google.com" from target clusters. The command is base64 encoded before being sent over this control channel.

curl --location --request POST 'https://app.phani-ptnr-1219.dev.rafay-edge.net/cmdexec/v1/projects/j2q4j5k/edges/3mxg7ek/execute/' \
--header 'X-RAFAY-API-KEYID: g5439debbd24b1c876aa79b4d2997bdca7009f3g' \
--header 'Content-Type: application/json' \
--data-raw '{
    "target_type" : "cluster",
    "command": "cGluZyAtYyAxIGdvb2dsZS5jb20KaWYgWyAkPyA9PSAwIF07IHRoZW4KICAgIGVjaG8gJ0Nvbm5lY3Rpb24gd29ya2luZycKZWxzZQogICAgZWNobyAnRXJyb3IgaW4gY29ubmVjdGlvbiB0byBVUkwnCmZpCg==",
    "content_type": "base64",
    "timeout": 120
}'

Once submitted, a response with a "Job ID" is returned. This Job ID should be used to query for results.

}

Retrieve Results

Use a GET request to the API Endpoint with the "Job ID" to retrieve results.

curl --location --request GET 'https://app.phani-ptnr-1219.dev.rafay-edge.net/cmdexec/v1/projects/j2q4j5k/edges/3mxg7ek/execution/dpkv0mn/' \
--header 'X-RAFAY-API-KEYID: g5439debbd24b1c876aa79b4d2997bdca7009f3g'
