Multiple Command-Node
This is an example of a multiple commands sent via the "zero trust host access" control channel to specific nodes in clusters.
Send Query¶
We want to send two distinct commands to the specified nodes
- free -h
- lsblk
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" : ["madhuarm-ubuntu201","madhuamd-ubuntu201"],
"target_type" : "node",
"command": "free -h ;lsblk",
"content_type": "string",
"timeout": 360
}'
Example Output
The output returns data and a "Job ID" which can then be used to query for results of the responses.
Retrieve Results¶
We will use 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/q6kn4ml/' \
--header 'X-RAFAY-API-KEYID: fg5439debbd24b1c876aa79b4d2997bdca7009f3g'
